I need help working this out, I only need help with question a.

Step-by-step explanation:

To determine whether the ice cream scoop will fit in the cone or overflow, we need to compare the volume of the scoop to the volume of the cone. If the volume of the scoop is less than or equal to the volume of the cone, the scoop will fit in the cone. If the volume of the scoop is greater than the volume of the cone, the scoop will overflow.

The formula for the volume of a sphere is:

V_sphere = (4/3)πr³

where r is the radius of the sphere. In this case, the radius of the ice cream scoop is 3 cm, so:

V_sphere = (4/3)π(3 cm)³ ≈ 113.1 cm³

The formula for the volume of a cone is:

V_cone = (1/3)πr²h

where r is the radius of the base of the cone and h is the height of the cone. In this case, the radius of the cone is also 3 cm and the height of the cone is 5 cm, so:

V_cone = (1/3)π(3 cm)²(5 cm) ≈ 47.1 cm³

Therefore, the volume of the ice cream scoop is greater than the volume of the cone, and the ice cream will overflow when it melts.

To explain this result, we can note that the volume of the ice cream scoop is determined by its shape and size, which cannot be changed. However, the volume of the cone is determined by both its shape and size, as well as the amount of space available inside it. When the ice cream melts, it will fill up the cone and displace the air inside, increasing the volume of the cone. However, the volume of the ice cream scoop will not change, so it will overflow the cone.

We don't know if she will reject the null hypothesis without knowing the level of significance. But if the p-value is smaller than the level of significance, she would reject the null hypothesis

The correct explanation for the P-value is option B: "If the​ P-value for a particular test statistic is ​, she expects results at least as extreme as the test statistic in about of 100 samples if the null hypothesis is true."

This means that if the null hypothesis is true, there is a certain probability (represented by the P-value) that we would observe a test statistic as extreme or more extreme than the one we observed in our sample.

As for the conclusion, we cannot determine whether or not the researcher would reject the null hypothesis based solely on the P-value. The decision to reject or not reject the null hypothesis depends on the level of significance (alpha) chosen by the researcher. If the P-value is smaller than the chosen alpha, then the researcher would reject the null hypothesis.

Otherwise, she would fail to reject it. Without knowing the level of significance chosen, we cannot determine the conclusion.

p(x), first, we need to divide the polynomials. Division of polynomials can be done by long division method. So, let's solve the problem and find the quotient and remainder of the polynomial.

In long division, first, we divide the first term of dividend by the first term of divisor.

3x^4/x^2 = 3x^2

Now we multiply this result (3x^2) with divisor and subtract from dividend.

3x^4 + 2x^3 - x^2 - x - 6 - (3x^2(x^2 + 1))= -3x^3 - x - 6

Next, we bring down the next term of the dividend. And repeat the process until we cannot divide further.

-3x^3/x^2 = -3x

Now, we multiply this result (-3x) with divisor and subtract from the last dividend.

The set of sample means generated by Mark may not be representative of the population of the city.

This is because Mark's sampling method is not random and may introduce bias into the sample. By only surveying bypassers in the central street, the sample may not be representative of the whole population of the city. On the other hand, Judy's random sampling method has a higher chance of capturing a representative sample of the population.

To confirm this, we can compare the sampling distributions generated by both methods. We can calculate the mean and standard deviation of the sample means for each method and compare them. If the means and standard deviations are significantly different, it may suggest that Mark's sampling method is biased.

To calculate the standard deviation of the sampling distribution, we can use the formula:

Since the population standard deviation is not given, we can use the sample standard deviation as an estimate. Assuming the sample standard deviation is 2, we can calculate the standard deviation of the sampling distribution as follows:

For Judy's method:

For Mark's method:

Assuming that the central street has a population size of 1000, we can calculate the standard deviation as:

y ≥ 0                     Non-negativity constraint

(3)
See attached graph

Step-by-step explanation:

(1)
Let x represent the number of HD Big View TV models produced
let y represent the number of MegaTeleBox models produced

(2)

Constraints
There are a total of 192 person hours per day to manufacture both models so this is the upper limit on the person-hours resource

Each unit of HD Big View takes 2 person-hours so x units will require 2x person-hours

Each unit of MegaTeleBox   takes 3 person-hours so y units will require 3y person-hours

Total person-hours to produce x and y units
= 2x + 3y
and this cannot exceed 192.

Therefore the first inequality is manpower resource constraint:
2x + 3y ≤ 192     [1]

Total manufacturing capacity is 72 units. The actual total production is
x + y and this cannot exceed 72

Second inequality is
x + y = 72             [2]

In addition the number of units produced cannot be less than zero. These are the non-negativity constraints:
x ≥ 0, y ≥ 0    [3]

Plugging in all these constraints we get the following system of inequalities

2x + 3y ≤ 192       [1]  manpower constraint
x + y = 72             [2]  production capacity constraint
x ≥ 0                     Non-negativity constraint

The minimum value of the function is 9, and the function never stops increasing.

The given function is y=(x−9)²+9.

We need to find the minimum and maximum value of the function. The given function is a quadratic function whose graph is a parabola. Since the coefficient of x² is positive, the graph of the quadratic function will be in the form of an upward parabola whose vertex is at the point (h,k).

The vertex form of the quadratic function is given byy = a(x - h)² + k, where(h,k) is the vertex of the parabola.

a is the coefficient of (x - h)².

In the given function,y = (x-9)² + 9, the vertex of this function is (9,9) and a=1.

Therefore, the minimum value of the function is 9 at x=9, which is the vertex of the parabola.

The function y=(x−9)²+9 is an upward parabola, and hence it never stops increasing, which means that the function has no maximum value.

Therefore the total cost for 18 months of membership is[tex]$742.50[/tex].The equation to find the cost of initiation and x months of membership is y + 59x = 742.50

The equation to find the cost of initiation and x months of membership is y + 59x = 742.50. Since the cost for one year of membership is known, the cost for initiation can be found by subtracting 59x from both sides of the equation, resulting in y = 742.50 - 59x. To find the total cost for 18 months of membership, we plug x = 18 into the equation, resulting in y + 59(18) = 742.50. This can be simplified to y + 1062 = 742.50, which means that y = -319.50. Therefore, the total cost for 18 months of membership is[tex]$742.50 - $319.50[/tex], which equals [tex]$423.00[/tex]. This calculation can be represented by the equation y + 59x = 742.50, where y is the cost of initiation and x is the number of months of membership. Plugging in the number of months of membership (x = 18) gives us the total cost for 18 months of membership (y + 1062 = 742.50).

Step-by-step explanation:

In this question we know 66 is 100% of the fraction, so we can start the process of converting a fraction into a percent, by figuring out how to adjust the fraction so that the denominator will be 100. First, divide 100 by the denominator.

100/66 = 1.515

Now we want to multiply denominator and numerator by 100.

34 × 1.515 = 51.515

66 × 1.515 = 100

Therefore, 34/66 as a percentage will be 51.515%

Now we want to convert 32/66. We will do the same for this equation.

100/66 = 1.515

32 × 1.515 = 48.485

66 × 1.515 = 100

Therefore 32/66 as a percentage will be 48.485

The best description of how close the prediction was to the actual population in 2013 is option (A) with in 100 people

To solve this problem, we can use the exponential growth formula:

P(t) = P0 × e^(rt)

where P(t) is the population at time t, P0 is the initial population, r is the growth rate, and e is the mathematical constant approximately equal to 2.718.

We can use the given data to find the growth rate r:

58,000 = 42,000 × e^(r×30)

Dividing both sides by 42,000:

e^(r×30) = 58,000/42,000 = 1.38

Taking the natural logarithm of both sides:

r×30 = ln(1.38)

r = ln(1.38)/30

r ≈ 0.0106

Now we can use this growth rate to predict the population in 2013:

P(53) = 42,000 × e^(0.0106×53) ≈ 74,480

So the predicted population of 74,480 is within 520 people of the actual population of 75,000
