Quantitative variables can be used to measure and contrast data because they have numerical values. They come in discrete or continuous forms. While continuous variables have an infinite number of possible values, such as decimal numbers, discrete variables have specific values, such as integers or whole numbers. Measurements like shoe size, height, weight, and temperature are examples of quantitative variables. Quantitative variables can be used to describe a population's varied characteristics, such as the median age or annual income of a given group. The average height of men and women, for example, might be used to compare two populations. The use of quantitative variables is crucial for comprehending and analyzing data. They enable academics to spot patterns and trends in data They enable researchers to find patterns and trends in data, anticipate the future, and form conclusions.

A bag contains 6 red marbles and 4 blue marbles. If two marbles are drawn at random and not replaced, what is the probability that two red marbles are drawn?

Answers

If two marbles are drawn at random and not replaced, the probability that two red marbles are drawn is; 1/3

What is the probability of selection?

The parameters given for marbles in the bag are;

Number of red marbles = 6

Number of blue marbles = 4

Thus;

Total number of marbles = 6 + 4

Total number of marbles = 10 marbles

Now, probability of first selection being red marble = 6/10

Probability of second marble being red if first was not replaced = 5/9

Thus;

P(first two being red marbles) = (6/10) * (5/9)

= 1/3

Interval notation: [tex]\left(-\infty \:,\:\infty \:\right)[/tex]

Range:

Interval notation: [tex]\left(1,\:\infty \:\right)[/tex]

c. See explanation below and on attached graph

d. See explanation below

Step-by-step explanation:

The function to be used for answering questions is
[tex]f(x) = 8\left(\dfrac{1}{4}\right)^{x+4}+1[/tex]

a. Graph

Graph is plotted using online graphing tool. 2 points identified are (-4, 9) and (-3, 3)

b. Domain and Range

First let's understand what domain and range are

Definition of domain

The domain of a function, y = f(x),  is the set of input(x)  values for which the function is real and defined

The function has no undefined points nor domain constraints.  You can see that the graph goes to infinity for negative and positive x values Therefore,  the domain is :

[tex]-\infty \: < x < \infty \:[/tex]

which can be expressed in interval notation as:

[tex]\left(-\infty \:,\:\infty \:\right)[/tex]

Definition of range

The range of a function y = f(x) is the set of values for y over the domain for which the function is defined

As [tex]x \rightarrow \infty[/tex], [tex]y \rightarrow 1[/tex]

y never quite reaches 0 but its value approaches 1 and therefore the range is
[tex]f(x) > 1\\\\[/tex]

In interval notation:
[tex]\left(1,\:\infty \:\right)[/tex]

c. End Behavior

The end behavior of a function  f(x)  refers to how the function behaves when the variable x  increases or decreases without bound. In other words, the end behavior describes the ultimate trend in the graph of f(x) as [tex]x \rightarrow \pm \infty[/tex]

In this particular function we see that as [tex]x\to \:+\infty \:,\:f\left(x\right)\to \:1\\[/tex]

and as [tex]x\to \:-\infty \:,\:f\left(x\right)\to \:\infty\\[/tex]

d. Point (-3, 3)
By pure chance I chose this point as one of the points asked for in part a because I was looking for integer values I don't think it matters that there is repetition

(-3, 3) is plotted on the graph as point A

3. Evaluate f(-3)
We have
[tex]f(x) = 8\left(\dfrac{1}{4}\right)^{x+4}+1[/tex]

To find f(-3) substitute -3 for x in the above function:

[tex]f(-3) = 8\left(\dfrac{1}{4}\right)^{-3+4}+1\\\\= 8\left(\dfrac{1}{4}\right)^1} + 1\\\\\\= 8\left(\dfrac{1}{4}\right) + 1\\\\= 2 + 1 \\\\= 3[/tex]

So f(-3) = 3

Answer:

a)  See attachment 1.

b)  Domain: (-∞, ∞)

     Range: (1, ∞)

c)  As x → -∞, f(x) → ∞

    As x → ∞, f(x) → 1⁺

d)  See attachment 2.

e)  See below.

Step-by-step explanation:

Given exponential function:

[tex]f(x)=8\left(\dfrac{1}{4}\right)^{x+4}+1[/tex]

Part a

To find the y-intercept, input x = 0 and solve for y:

[tex]\implies f(0)=8\left(\dfrac{1}{4}\right)^{0+4}+1[/tex]

[tex]\implies f(0)=8\left(\dfrac{1}{4}\right)^{4}+1[/tex]

[tex]\implies f(0)=8\left(\dfrac{1}{256}\right)+1[/tex]

[tex]\implies f(0)=\dfrac{1}{32}+1[/tex]

[tex]\implies f(0)=\dfrac{33}{32}[/tex]

[tex]\implies f(0)=1.03125[/tex]

Therefore, the y-intercept is (0, 1.03125).

Substitute x = -2 into the function to find a second point on the curve:

[tex]\implies f(-2)=8\left(\dfrac{1}{4}\right)^{-2+4}+1[/tex]

[tex]\implies f(-2)=8\left(\dfrac{1}{4}\right)^{2}+1[/tex]

[tex]\implies f(-2)=8\left(\dfrac{1}{16}\right)+1[/tex]

[tex]\implies f(-2)=\dfrac{1}{2}+1[/tex]

[tex]\implies f(-2)=\dfrac{3}{2}[/tex]

[tex]\implies f(-2)=1.5[/tex]

Therefore, a second point on the curve is (-2, 1.5).

Part b

The domain of a function is the set of all possible input values (x-values).  

The domain of the given function is unrestricted:

Interval notation: (-∞, ∞)

The range of a function is the set of all possible output values (y-values).

As the exponential part of the function is always positive, the range of the given function is restricted:

Interval notation: (1, ∞)

Part c

As x approaches negative infinity, the function approaches positive infinity:

As x → -∞, f(x) → ∞

As x approaches positive infinity, the function approaches f(x) = 1.

As x → ∞, f(x) → 1⁺

Part d

See attachment 2.

Part e

Substitute x = -3 into the function:

[tex]\implies f(-3)=8\left(\dfrac{1}{4}\right)^{-3+4}+1[/tex]

[tex]\implies f(-3)=8\left(\dfrac{1}{4}\right)^{1}+1[/tex]

[tex]\implies f(-3)=8\left(\dfrac{1}{4}\right)+1[/tex]

[tex]\implies f(-3)=2+1[/tex]

[tex]\implies f(-3)=3[/tex]  

the opportunity cost of producing one bushel of wheat in canada is equal to 1/2 tv set. the opportunity cost of producing one bushel of wheat in the us is 2 tv sets. if these two countries specialize according to comparative advantage and then trade with each other, .

Answers

If Canada specializes in producing wheat and the US specializes in producing TV sets, both countries will benefit from trade.

To determine this if Canada produces wheat, the opportunity cost is 1/2 TV set. If the US produces wheat, the opportunity cost is 2 TV sets. So, Canada has a comparative advantage in producing wheat. Similarly, the US has a comparative advantage in producing TV sets.

Let's say Canada produces 100 bushels of wheat, and the US produces 100 TV sets. If they trade with each other, Canada can exchange 50 bushels of wheat for 50 TV sets, and the US can exchange 50 TV sets for 50 bushels of wheat. Both countries would benefit from this trade.

Canada would end up with 50 TV sets and 50 bushels of wheat, while the US would end up with 50 bushels of wheat and 50 TV sets. Both countries would be better off than if they had not traded.

Opportunity cost in mathematics is a term that is used to describe the cost of one alternative in terms of the benefits forgone by the best alternative. It can also be represented in terms of mathematical equations.

What is Trigonometry?

The area of mathematics known as trigonometry examines the correlation between the ratios of a right-angled triangle's sides to its angles. Trigonometric ratios, such as sine, cosine, tangent, cotangent, secant, and cosecant, are used to study this relationship. The concept of trigonometry was developed by the Greek mathematician Hipparchus, and the word trigonometry is a derivative of Latin from the 16th century.

One of the most significant area of mathematic is rigometry. The words "Trigonon" and "Metron," which mean respectively "triangle" and "measure," are combined to form the word "trigonometry." It is the investigation of how a right-angled triangle's sides and angles relate to one another. Therefore, using formulas and identities based on this relationship aids in determining the measure of a right-angled triangle's unknown dimensions.

How do i solve for value of m

Answers

Hi there!
From my best knowledge I assume this has to do with triangle angles and linear expressions.
All triangles add up to 180°, so we will use this formula with the triangle angels given.
(4m + 6) + (5m + 3) = 180°
9m + 9 = 180°
(Combined like terms) 4+5 & 6+3
9m = 171 (Subtract 9 from 180 = 171)
m = 19 (Divide 9 from 171)

So, m in the expression equals 19 but let’s double check.
(4(19) + 6) + (5(19) + 3) = 180
4 x 19 = 76 + 6 = 82°
(So that angle separately is 82 degrees.)
5 x 19 = 95 + 3 = 98°
(So that angle separately is 98 degrees.)
Add both angles - 82° + 98° = 180°
So it’s a true formula! Both angles in the triangle add to 180 as it should.
But as for the original question being asked, yes m = 19
= m = 19

A farmer has enough food to feed 20 animals in his cattle for 6 days. How long
would the food last if there were 10 more animals in his cattle?

Answers

Answer:

4 daysb

Step-by-step explanation:

Here the number of animals and the number of days are in inverse proportion. Hence the food will last 4 days.

The food will last for 6 days for 20 animals.

If there were 10 more animals in the cattle, the total number of animals would be 20+10 = 30.

The food will last for the same 6 days but now it would be divided among 30 animals.

Therefore, the food would last for 6 days / 30 animals = 0.2 days per animal.

So, the food will last for 0.2 days if there were 10 more animals in the farmer's cattle.

Using expression {River=x(race)} River's length is 7.38 times the race's length, approximately.

What are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

We know that

The river is 310 miles long.

The race is 42 miles long.

So, if we want to know know how many times as long as the race is the river, we just need to use this expression

River=x(race)

Where x represents the factor that expresses the ratio between both, solving for x we have

x=river/race=310/42≈7.38

Therefore,

How to find a area of triangle using trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. It can be used to calculate the area of a triangle by using the length of its sides.

The most commonly used formula to calculate the area of a triangle is known as Heron's formula. This formula uses the lengths of the triangle's three sides, known as a, b, and c. Then use the formula A = 1/2 x[tex]\sqrt{(a + b+ c)(-a + b + c)(a - b + c)(a + b -c)}[/tex] to calculate the area of the triangle.

To calculate the area of a triangle using Heron's formula, first measure the length of each side of the triangle. Then use the lengths of the sides to calculate s using the formula above. Once you have calculated s, plug the values for a, b, and c into Heron's formula to calculate the area of the triangle.

A = 1/2ab⋅sin(C)

Answers

Answer:

The equation 49^2 + 16^2 = 784 can be rewritten as (x/24.5)^2 + (y/8)^2 = 1.

The standard form of an ellipse is (x/a)^2 + (y/b)^2 = 1, where a and b are the lengths of the major and minor axes, respectively. In this case, a = 24.5 and b = 8.

To graph the ellipse, we can use the equation in the standard form and plot points that satisfy the equation. The center of the ellipse is (0,0) and it has a major axis of 24.5 and minor axis of 8.

The graph of this ellipse will look like an oval, with the center at the origin, major axis along the x-axis and minor axis along the y-axis.

The  height of the roof will be -

S(max) = - t² + 3t + 4

S(3/2) = - (3/2)² +(3 x 3/2) + 4

S(3/2) = 9/4 + 9/2 + 4

S(3/2) = 2.25 + 4.5 + 4

S(3/2) = 10.75 units.

Therefore, the height of the roof will be 10.75 units.

a researcher randomly assigned boys and girls to each of two groups. one group watched a violent television program while the other group watched a nonviolent program. the children were then observed during a period of free play, and the incidence of aggressive behavior was recorded for each group. experimental
case study
correlational
observation

Answers

This method of observing the behaviour of each group of children is best characterized as experimental.

Experimental research is a study worked with a scientific approach using two sets of variables. The first set works as a constant, which we use to measure the differences of the second set.

This can be regarded as something that depends on other factors, such as a test score, which can be considered a dependent variable because it could change depending on several factors, such as how much you studied.

It should be noted that dependent and independent variables are variables in mathematical modelling and experimental sciences; however, the dependent variables can be seen as ones whose values are studied under the supposition.

Hence the correct option is a.

A bank loaned out $12,000, part of it at the rate of 6% per year and the rest at the rate of 16% per year. If the interest received totaled$1000, how much was loaned at 6%?

Answers

The amount loaned at 6% was $9200. The solution has been obtained by making and solving the equations.

What is an equation?

A claim that two expressions are equal and connected by the equals sign "=" is the mathematical definition of an equation. The two expressions need not be entirely composed of variables; one expression may have variables while the other may not.

We are given that a bank loaned out $12,000 and a part of it at the rate of 6% per year and the rest at the rate of 16% per year.

Let the amount loaned at 6% be 'x'

So, amount loaned at 16% will be '12,000 - x'

The total interest received was $1000.

Therefore,

⇒6%x + 16%(12000-x) = 1000

⇒0.06x + 1920 - 0.16x = 1000

⇒920 = 0.1x

9200 = x

Hence, the amount loaned at 6% was $9200.

Bridge is a card game in which the deck of 52 cards is randomly and equally divided among the 4 players.So each player gets 13 cards. What is the probability that one player receives all the 13 hearts?

Answers

The probability that one player receives all the 13 hearts is 1/2598960.

How likely something is to occur can be determined using probability. For many events, it is challenging to make an accurate prediction.

The number of ways to distribute the 13 hearts among the 4 players is 4!. The number of ways to distribute the remaining 39 cards among the 4 players is 39!/(13!13!13!13!). Hence, the total number of ways to distribute the 52 cards among the 4 players is (52!)/(13!13!13!13!).

Therefore, the probability that one player receives all the 13 hearts is (4!)/((52!)/(13!13!13!13!)) = 1/((52515049)/(13121110)) = 1/2,598,960.

integrate both sides of the differential equation you found for dp to obtain an equation for p . your equation should then include a constant that depends on initial conditions. determine the value of this constant by assuming that the pressure at some reference height y0 is p0 .

Answers

The value of this constant, by assuming that the pressure at some reference height y₀ is p₀, is p - p₀ = p.g(y₀ - y).

dp = -pg dy

At height y = y₀ and p = p₀

∫dp = ∫-pg dy

⇒p = -pgy + C        Eqn(1)

Where c is the constant of integration

We know that y = y₀ and p = p₀

⇒p₀ = -pgy₀ + C

⇒C = p₀ + pgy₀

Put the value of C in Eqn(1)

⇒p = -pgy + p₀ + pgy₀

⇒p - p₀ = -pgy + pgy₀

⇒p - p₀ = pg(y₀ - y)

F(v) = ____ Use the polynomial to estimate the force on the projectile when it is traveling at 750 ftlsec:

Answers

The estimated force on the projectile when it is traveling at 750 ft/sec is approximately 696.7 lbs.

The Possible Interpolating Polynomial

One possible interpolating polynomial for these data points is a polynomial of degree 3, also known as a cubic polynomial. Using software or a calculator to fit a cubic polynomial to the data points, the resulting equation is:

F(v) = -0.00000016v³ + 0.0004v² - 0.08v + 0.4

To estimate the force on the projectile when it is traveling at 750 ft/sec, we can substitute 750 for v in the equation above:

F(750) = -0.00000016(750³) + 0.0004(750²) - 0.08(750) + 0.4

F(750) ≈ 696.7

The estimated force on the projectile when it is traveling at 750 ft/sec is approximately 696.7 lbs.
