Option D : Based on the given data, the best prediction for the number of students who prefer ice cream at the college, which is approximately 1,440 students.
To make prediction of the number of students who prefer ice cream, we need to use the proportion of students who prefer ice cream from the sample to the entire population of 4,000 students.
Based on the given data, 81 out of 225 students prefer ice cream. To estimate the number of students who prefer ice cream in the entire college, we can use the ratio of students who prefer ice cream in the sample to the total number of students in the college.
The total number of students in the college is 4,000, so we can set up a proportion:
81/225 = x/4000
Solving for x, we get:
x = (81/225) * 4000 = 1,440
Therefore, the best prediction for the number of students who prefer ice cream in the entire college is 1,440.

r(x)= x^2 + 3x - 10/ (x+1)(x-3)(x+5)
The y-intercept of the equation is -10.
What is Equation?Equation is a mathematical statement that expresses the equality of two expressions, which are separated by an equals sign. It can be used to represent a variety of different relationships, such as equality, inequality, addition, subtraction, multiplication, and division. Equations can be used to solve a variety of problems in science, engineering, and mathematics.
The x-intercepts of the graph of the equation r(x) are those values of x for which the equation is equal to 0. To find the x-intercepts, we must solve the equation:
x²+ 3x - 10 = 0
Factoring the equation, we get:
(x+5)(x-3)(x+1) = 0
The solutions of this equation are x = -5, -1, and 3. Therefore, the x-intercepts of the equation are -5, -1, and 3.
To find the y-intercept, we must plug 0 in for x in the equation:
y = x² + 3x - 10/ (x+1)(x-3)(x+5)
When x = 0, we get:
y = -10/ (0+1)(0-3)(0+5)
Therefore, the y-intercept of the equation is -10.
The vertical asymptote of the equation is the line x = -1, since it is the only value of x that makes the denominator equal to 0.
The horizontal asymptote of the equation is the line y = 0, since the degree of the numerator is less than the degree of the denominator.

Find the two linearly independent solutions of the LODE following for x>0, and determine at least the first four leading terms in the second solution y(2). 9x²y" - 6xy' + 2y = 0
Please, I need the solution
Using Cauchy-Euler equation, the solution of the second-order homogeneous differential equation is y2(x) = c3 * x^(1/3) + c4 * x^(4/3) - (1/2) * c4 * x
What is the solution to the equationThe given LODE is a second-order homogeneous differential equation with constant coefficients. The characteristic equation is given by:
9r^2 - 6r + 2 = 0
Using the quadratic formula, we find the roots to be:
r = (1/3) ± i/sqrt(3)
Thus, the general solution to the differential equation is:
y(x) = c1 * x^(1/3) * cos((1/3)*arccos(sqrt(3)*r)) + c2 * x^(1/3) * sin((1/3)*arccos(sqrt(3)*r))
To find the first solution, we can choose either the cosine or sine term. Let's choose the cosine term for simplicity:
y1(x) = x^(1/3) * cos((1/3)*arccos(sqrt(3)*r))
To find the second solution, we can use the method of reduction of order. Assume that the second solution has the form:
y2(x) = v(x) * y1(x)
Substituting this into the differential equation, we obtain:
9x^2(v''(x)*y1(x) + 2v'(x)*y1'(x) + v(x)*y1''(x)) - 6x(v'(x)*y1(x) + v(x)*y1'(x)) + 2v(x)*y1(x) = 0
Simplifying this equation by dividing by x^2*y1(x), we get:
9v''(x) + (18/r)x*v'(x) + ((2/r^2) - 1)v(x) = 0
where r = sqrt(3)
This is a Cauchy-Euler equation, which can be solved by assuming a solution of the form:
v(x) = x^m
Substituting this into the equation, we obtain:
9m(m-1) + (18/r)m + ((2/r^2) - 1) = 0
Simplifying this equation, we get:
9m^2 + 6m + 1 = 0
Using the quadratic formula, we find the roots to be:
m = (-1/3) or (-1/3)
Thus, the second solution is given by:
y2(x) = c3 * x^(1/3) + c4 * x^(1/3) * ln(x)
To determine the first four leading terms in the second solution, we can use the Taylor series expansion of the natural logarithm:
ln(x) = (x-1) - (1/2)(x-1)^2 + (1/3)(x-1)^3 - ...
Substituting this into the second solution, we obtain:
y2(x) = c3 * x^(1/3) + c4 * x^(1/3) * [(x-1) - (1/2)(x-1)^2 + (1/3)(x-1)^3 - ...]
Simplifying this expression, we get:
y2(x) = c3 * x^(1/3) + c4 * x^(1/3) * (x-1) - c4 * x^(1/6) * (1/2)(x-1)^2 + c4 * x^(1/3) * (1/3)(x-1)^3 - ...
Thus, the first four leading terms in the second solution are:
y2(x) = c3 * x^(1/3) + c4 * x^(4/3) - (1/2) * c4 * x

Step-by-step explanation:
A secretary listed the frequency of calls by a patient to a doctor's office during a year, and the data is displayed in the histogram.
A histogram titled Calls To A Doctor. The x-axis is labeled Number of Calls and has intervals listed for 1 to 25, 26 to 50, 51 to 75, and 76 to 100. The y-axis is labeled Frequency and begins at 0, with tick marks every five units up to 60. There is a shaded bar for 1 to 25 that stops at 58, for 26 to 50 that stops at 34, for 51 to 75 that stops at 17, and for 76 to 100 that stops at 12.
Which of the following best describes the spread and distribution of the data?
The data is skewed to the higher values because many patients call the doctor several times a day when they are sick.
The data is skewed to the lower values because many patients only call the doctor once or twice a year when they are sick.
The data is bimodal with a narrow spread because many patients call the doctor several times a day when they are sick.
The data is normal and has a wide spread because many patients only call the doctor once or twice a year when they are sick.
The data is skewed to the lower values because many patients only call the doctor once or twice a year when they are sick.
Define the terms spread and distribution?Spread and distribution of data are statistical concepts that describe how a set of data is spread out or distributed.
Distribution refers to how the data is distributed or arranged. It is typically described in terms of its shape, center, and spread. Common types of distributions include normal distribution, skewed distribution, and uniform distribution. The distribution can be visualized using various graphs such as histograms, box plots, and scatter plots.
Based on the histogram description, the best answer is:
The data is skewed to the lower values because many patients only call the doctor once or twice a year when they are sick.
The histogram shows that the frequency of calls is highest for the 1 to 25 interval, with decreasing frequency for each subsequent interval. The fact that the shaded bars stop at relatively low frequencies for each interval suggests that there are very few patients who call the doctor frequently, skewing the data towards the lower values. The histogram also shows a wide range of values, or spread, with the highest interval going up to 100, but the low frequencies in each interval suggest that the data is not normally distributed.

Which number best describes a typical rating in the contest?
0.8
7.4
7.9
9.7
The answer of the given question based on the number best describes a typical rating in the contest the answer is 7.9.
What is Median?The median is measure of central tendency in statistics that represents middle value of dataset. It is value that separates highest 50% of values from the lowest 50%.
To find median of a dataset, you first need to sort data in ascending or descending order.
The median rating is 7.9, which means that half of the contestants scored above 7.9 and half scored below. This suggests that 7.9 is a representative value of the ratings overall.
Additionally, the interquartile range (IQR) is a measure of the spread of the middle 50% of the ratings, and it is given as 0.8. This means that the ratings between the 25th and 75th percentile fall within a range of 0.8, which suggests that the ratings are fairly tightly clustered around the median of 7.9.
Therefore, the number that best describes a typical rating in the contest is 7.9.

A cuboid has faces with areas 24, 32, and 48 square centimeters. what are the lengths of its sides?
Answer:
Let's denote the length, width, and
height of the cuboid as "l", "w", and
"h, respectively. Then, we have:
lw= 24 (Area of one face)
Ih 32 (Area of another face)
wh 48 (Area of the third face)
To solve for the dimensions of the
cuboid, we can use a system of
equations. We can start by solving
for one of the variables in terms of
the other two. For example, from the
first equation, we have:
W 24/
Substituting this into the second
equation, we get:
Ih 32
I(24/)h = 32
24h 32
h 32/24
h 4/3
Next, we can substitute the values of
h and w into the third equation to
solve for:
wh = 48
I(24/)(4/3) = 48
I2 72
= sqrt(72)
I= 6sqrt(2)
Finally, we can use the values of I
and w to solve for the remaining
dimension:
lw 24
(6sqrt(2))(24/(6sqrt(2))) = 24
W = 4sqrt(2)
Therefore, the lengths of the sides of
the cuboid are:
Length () = 6v2 cm
Width (w) = 4/2 cm
Height (h) = 4/3 cm

A family drives 509 miles to their vacation destination. It takes them 8.6 hours to get there. What was their average velocity in miles per hour?
Answer:
Their average velocity during their trip was 59.19 miles per hour.
Step-by-step explanation:
To calculate the average velocity of the family's trip, we divide the total distance traveled by the time it took to travel that distance:
Average velocity = total distance ÷ time
In this case, the total distance traveled is 509 miles and the time it took to travel that distance is 8.6 hours. So, we can plug these values into the formula:
Average velocity = 509 miles ÷ 8.6 hours
Simplifying this equation, we get:
Average velocity = 59.19 miles per hour (rounded to two decimal places)
Therefore, the family's average velocity during their trip was 59.19 miles per hour.
There are 88 seats in a theater. The seating in the theater is split into 4 identical sections. Each section has 14 red seats and some blue seats.
write an exspression
Answer:
x = 8
Step-by-step explanation:
Let x be the number of blue seats in each section.
Then the total number of seats in each section is:
14 + x
Since there are 4 identical sections, the total number of seats in the theater is:
4(14 + x) = 56 + 4x
We know that the theater has 88 seats, so:
56 + 4x = 88
Simplifying the equation:
4x = 32
x = 8
Therefore, each section has 14 red seats and 8 blue seats.
The expression for the number of blue seats in each section is x = 8.
Answer:
4(14 + b) = 88---------------------------------
Let b be the number of blue seats.
There are 4 sections, each has 14 red and b blue seats, with the total number of seats being 88.
The equation to reflect this would be:
4(14 + b) = 88Its solution would be:
14 + b = 88/414 + b = 22b = 22 - 14b = 8Factor completely using the GCMF.
10x5 + 8x4 - 4x²
Answer:
To factor completely using the GCMF (Greatest Common Monomial Factor), we first need to identify the common monomial factor of all three terms. In this case, the common monomial factor is 2x²:
10x^5 + 8x^4 - 4x² = 2x²(5x^3 + 4x^2 - 2)
Now, we can see that the expression can be factored further, but it cannot be factored using the GCMF. However, we can use other factoring techniques, such as grouping or factoring by grouping, to factor the remaining expression:
2x²(5x^3 + 4x^2 - 2) = 2x²(5x^3 + 10x^2 - 6x^2 - 2)
= 2x²(5x^2(x + 2) - 2(x + 2))
= 2x²(5x^2 - 2)(x + 2)
Therefore, the expression 10x^5 + 8x^4 - 4x² can be factored completely as 2x²(5x^2 - 2)(x + 2).

A circle has a circumference of 20 ft. What is the
radius of the circle?
Step-by-step explanation:
The formula to calculate the circumference of a circle is:
Circumference = 2πr
where "r" is the radius of the circle and "π" is the mathematical constant pi, approximately equal to 3.14159.
Given that the circumference of the circle is 20 ft, we can plug in the values into the formula and solve for "r":
20 = 2πr
Divide both sides of the equation by 2π:
r = 20 / (2π)
Simplify the expression by using the approximation of π as 3.14159:
r = 20 / (2 x 3.14159)
r = 3.1831 ft (rounded to four decimal places)
Therefore, the radius of the circle is approximately 3.1831 feet.
Given that Z=√3 + √3 i, write Z in Euler form
Answer:
To write Z in Euler form, we first need to find its magnitude and argument.
The magnitude of Z is given by:
|Z| = √(Re(Z)^2 + Im(Z)^2)
where Re(Z) is the real part of Z, and Im(Z) is the imaginary part of Z.
In this case:
Re(Z) = √3
Im(Z) = √3 i
So:
|Z| = √(√3^2 + (√3)^2) = √(3 + 3) = √6
The argument of Z is given by:
arg(Z) = tan^(-1)(Im(Z) / Re(Z))
In this case:
arg(Z) = tan^(-1)((√3) / √3) = tan^(-1)(1) = π/4
Therefore, Z in Euler form is:
Z = |Z| e^(i arg(Z)) = √6 e^(i π/To write Z in Euler form, we first need to find its magnitude and argument.

What is the solution to 4^x = 5^x +^2
The solution to 4^x = 5^x +^2 is
x = -2log 5/( log 5 - log 4)
Option C is correct.
How do we calculate?We will rewrite the equation as:
4^x = 5^x * 5^2
applying the logarithm function to both sides of the equation.
log(4^x) = log(5^x * 5^2)
simplifying the right side of the equation, using the properties of logarithms,
log(4^x) = log(5^x) + log(5^2)
log(4^x) = xlog(4) = x2log(2)
log(5^x) + log(5^2) = xlog(5) + log(25)
Substituting these results back into the original equation, we have:
x2log(2) = x*log(5) + log(25)
x*(2*log(2) - log(5)) = log(25)
Divide both sides by (2*log(2) - log(5)), we get:
x = x = -2log 5/( log 5 - log 4)

What would (-2, -2) be if it is rotated 90 degrees clockwise?
Answer:
(2, -2)
Step-by-step explanation:
To rotate a point in a coordinate plane 90 degrees clockwise, we need to switch the x and y coordinates and negate the new x coordinate.
So let's apply this formula to the point (-2, -2):
- The new x-coordinate will be the original y-coordinate: -2
- The new y-coordinate will be the negation of the original x-coordinate: -(-2) = 2
Therefore, after rotating (-2, -2) 90 degrees clockwise, we get the point (2, -2).
We can visualize this by plotting both points on a coordinate plane and drawing a line of reflection that represents the rotation:
```
Before rotation:
|
|
|
-------+-------
|
(-2,-2)
After rotation:
|
|
(2,-2)|
-------+-------

```
As shown in the diagram above, after rotating (-2,-2) 90 degrees clockwise, it lands at (2,-2).

According the question 89+82 expressiοn is the same as 8(9+2).
What is expressiοn?An expressiοn in math is a sentence with a minimum οf twο numbers οr variables and at least οne math οperatiοn. This math οperatiοn can be additiοn, subtractiοn, multiplicatiοn, οr divisiοn.
Algebraic expressiοns are classified οn the basis οf the number οf terms in the expressiοn. The variοus types οf algebraic expressiοns are:
Mοnοmial expressiοnsBinοmial expressiοnsTrinοmial expressiοnsPοlynοmial expressiοnsThe difference between expressiοns and equatiοns is that an expressiοn signifies a cοmbinatiοn οf numbers, variables, and οperatiοn symbοls whereas an equatiοn will always use an equal (=) οperatοr between twο math expressiοns.
The expressiοn 8(9+2) can be simplified using the distributive prοperty οf multiplicatiοn οver additiοn:
8(9+2) = 89 + 82
Therefοre, the answer is: 89+82

A high school drama club is selling tickets for the spring production. One day the president sold 12 adult tickets and 5 child tickets for a total of $169. The next day the president sold 22 adult tickets and 10 child tickets for a total of $314. Let a represent the cost of one adult ticket. Let c represent the cost of one child ticket. Which system of equations will solve for a and c?
12 a + 5 c = 314. 22 a + 10 c = 169.
12 a + 5 c = 169. 22 a + 10 c = 314.
5 a + 12 c = 314. 22 a + 10 c = 169.
22 a + 5 c = 169. 12 a + 10 c = 314.
Mark this and return

What is system οf equatiοn?A system οf linear equatiοns can be sοlved graphically, by substitutiοn, by eliminatiοn, and by the use οf matrices.
The cοrrect system οf equatiοns tο sοlve fοr a and c is:
12a + 5c = 169 (equatiοn 1)
22a + 10c = 314 (equatiοn 2)
These equatiοns represent the tοtal ticket sales and revenue οn twο different days.
Tο sοlve this system, we can use the methοd οf eliminatiοn.
-24a - 10c = -338
22a + 10c = 314
-2a = -24

a = 12
Nοw we can substitute a = 12 intο equatiοn 1 tο sοlve fοr c:
12(12) + 5c = 169
144 + 5c = 169
5c = 25
c = 5
Therefοre, the cοst οf οne adult ticket is $12 and the cοst οf οne child ticket is $5.

Is -3 a real irrational rational integer or a whole number 
-3 is not an irrational number, but it is a real number, a rational number, an integer, and a whole number.
What are whole numbers and rational numbers?
All numbers, including integers, fractions, decimals, and irrational numbers, that can be represented on a number line are considered real numbers.
In summary, real numbers include rational and irrational numbers, and integers include whole number and their negatives.
When two integers are compared, a number can be stated as a ratio, such as -3/1, 1/2, or 5/7. Writing rational numbers as recurring or ending decimals is an option.
Numbers that can't be stated as a ratio of two integers, like 2 or, are referred to as irrational numbers. It is impossible to write irrational numbers using repeating or ending decimals.
Positive and negative whole numbers, as well as zero, are considered integers. Since whole numbers are non-negative integers, they contain zero and only positive values.
