H0: There is no link between state and preferred sport.

H1: There is a connection between state and preferred sport.

Given,

The question to be answered is whether the factor "state" and the factor "sporting choice" are related.

Therefore, the focus of the study is on "association" and whether or not state-to-state variations in athletic preference distributions exist. The most appropriate test in this instance is the test for association.

Unless there is evidence to the contrary, two things are assumed to not be related. Since the null hypothesis is assumed to be true, the following two hypotheses are the proper pair:

H0: There is no connection between a person's state and their preferred sport.

H1: The choice for sports and state are related.

y = mx + b where m is the rate of change and b is the y-intercept, describes the linear relationship between rise in temperature (y) and change in time (x) from 6 to 24 minutes.

To calculate the linear equation, we can use the Point-Slope Form of a Line formula, y = mx + b. To find the slope (m), we must calculate the rise (change in the y-value) over the run (change in the x-value). We must calculate the temperature difference between 6 minutes (T1) and 24 minutes (T2). Then, divide the temperature difference by the time difference of 18 minutes. The y-intercept (b) can be found by plugging in the known x and y values of 6 minutes and T1 respectively into the equation y = mx + b. Once we have the slope and y-intercept, we can plug them into the equation y = mx + b to calculate the equation that describes the linear relationship between the rise in temperature (y) and change in time (x) from 6 to 24 minutes.

y = mx + b, where

m = (T2 - T1)/(24 - 6) = (T2 - T1)/18

b = T1 - (m*6)

y = (T2 - T1)/18 * x + (T1 - (m*6))

The substitution method for solving equations is the method that can be used in a quadratic equation whereby one equation is solved and substituted into the next equation.

The given equation such as;

4x - 5y = 7 ---> eq 1

4X -9y = -4---> eq 2

From eq1 make 4x the subject of formula

4x = 7 + 5y

Substitute for 4x in equation 2;

7 + 5y - 9y = -4

7 - 4y = -4

7+4 = 4y

11 = 4y

y = 11/4

y = 2.75

Then substitute y = 2.75 into equation 1;

4x - 5y = 7

4x - 5(2.75) = 7

4x - 13.75 = 7

4x = 7 + 13.75

4x = 20.75

X = 20.75/4

X = 5.2

The doubling time is approximately 83 years. This means that it will take approximately 83 years for the squirrel population to double from its initial size of 450 squirrels.

What is an exponential function?

An exponential function is a function in which the variable appears in the exponent. Exponential functions have the form y = ab^x, where a and b are constants and x is the variable. The constant b is called the base of the exponential function.

The given information states that the squirrel population P(t) follows a logistic growth model with a growth constant k = 0.8 yr-1 and a carrying capacity of 1800 squirrels. The formula for the squirrel population P(t) can be found using the logistic growth model:

P(t) = K / (1 + (K/P0 - 1) * e^(-kt))

where P0 is the initial population of squirrels, K is the carrying capacity, and t is time in years.

Substituting the given values into the formula, we get:

P(t) = 1800 / (1 + (1800/450 - 1) * e^(-0.8t))

Simplifying the equation, we get:

P(t) = 1800 / (1 + 3e^(-0.8t))

This is the formula for the squirrel population P(t).

To find the doubling time (the time it takes for the squirrel population to double), we need to find the time t at which the squirrel population reaches twice the initial population of 450 squirrels. This can be represented by the equation:

2 * 450 = 1800 / (1 + 3e^(-0.8t))

Solving for t, we get:

0.8t = ln(3)

t = ln(3) / 0.8

Hence, the doubling time is approximately 83 years. This means that it will take approximately 83 years for the squirrel population to double from its initial size of 450 squirrels.

According to the question,

Given value = [tex]500[/tex] [tex]ft^{3}[/tex] tanks is to be built which has to be a square-based rectangle steel holding tank.

For this, we have to know the total surface area of the box,

Surface area (A) = 4 x sides of the rectangle + square base -- equation 1

Let's take the width of the square base = p

And let height = h

Since we know that,

Rectangle sides = p x h

Square base ⇒ p x p = [tex]p^{2}[/tex]

Substituting these values in equation 1,

Surface area ( A ) = 4 x ( p x h ) + [tex]p^{2}[/tex] ---- equation 2

V = [tex]p^{2}[/tex] x h --- equation 3

Referring to the question that the value of the volume is already given such that volume = [tex]500[/tex] [tex]ft^{3}[/tex]

So, V = [tex]500[/tex] [tex]ft^{3}[/tex]

Putting the value of V in equation 3,

500 = [tex]p^{2}[/tex] x h

h = [tex]\frac{500}{p^{2} }[/tex] ---- equation 4

Substituting the value of h from equation 4 to equation 2,

A = 4 x ( p x [tex]\frac{500}{p^{2} }[/tex] ) + [tex]p^{2}[/tex]

⇒ A = [tex]\frac{2000}{P}[/tex] + [tex]p^{2}[/tex]

We will be taking the derivative of the above equation,

⇒ A' = - [tex]\frac{2000}{p^{2} }[/tex] + 2p

Now we will be minimizing A,

⇒ 0 = - [tex]\frac{2000}{p^{2} }[/tex] + 2[tex]p[/tex]

⇒ [tex]\frac{2000}{p^{2} }[/tex] = 2[tex]p[/tex]

⇒ 2000 = 2[tex]p^{3}[/tex]

⇒ 1000 = [tex]p^{3}[/tex]

⇒ p = [tex]\sqrt[3]{1000}[/tex]

⇒ p = 10 foot

Substituting the value of p in equation 4,

⇒ h = [tex]\frac{500}{10^{2} }[/tex]

⇒ h = [tex]\frac{500}{100}[/tex]

⇒ h = 5 foot

Substituting values in the area of the square box,

A = 4 x (10 x 5) + [tex]5^{2}[/tex]

A = 200 + 25

A = 225 [tex]ft^{2}[/tex]

The weight of the metal,

⇒ weight = A x weight per square foot

⇒ weight = 225 x 5

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Step-by-step explanation:

Using the pythagorean theorem, we know that

     a^2 + b^2 = c^2

In this case,

c = 4, which means that a^2 + b^2 = 16

Since we know that a = 3, this means that a^2 is also 9. So, we know that b^2 = 16-9

Therefore, b^2 = 7

So, the answer is √7.

Although part of your question is missing, you might be referring to this full question: Write an expression that describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term. –1, 0, 1, 2, ...

The expression that describes the given sequence is: aₙ = –2 + n

This is an arithmetic sequence. Arithmetic sequence is a sequence of numbers in which every term (except the first term) is provided by adding a constant number to the previous term.

An arithmetic sequence can be defined by an explicit formula in which aₙ = d (n – 1) + c, where d is the common difference between consecutive terms, and c = a₁.

In this case, the given sequence is –1, 0, 1, 2, ...

This is an arithmetic sequence with common difference.

Because of:

0 – (–1) = 1

1 – 0 = 1

2 – 1 = 1 …

Then, a₁ = –1

Now, substitute the value of a₁ = –1, d = 1 into the formula.

aₙ = d (n – 1) + c

aₙ = 1 (n – 1) + (–1)

aₙ = n + (–2)

aₙ = –2 + n

Hence, the expression that describes the given sequence is: aₙ = –2 + n.

The best measure of center for the frequency of the data is Mean. The value of the measure of the center is 30.

The Mean value refers to an intermediate value between a discrete set of numbers. It is a measure of central tendency in a data set. In statistics, the term average refers to any of the measures of central tendency. The arithmetic mean of a set of observed data is defined as being equal to the sum of the numerical values of each and every observation, divided by the total number of observations. Fifty part time college students were asked how many hours they work per week.

Frequency 12 10 81 6 0 10 30 40 0 10 30 40 20 Hours 20 Hours.

We reject null hypothesis when hypothesis test, draw conclusions at significance level 0.08.

Given that,

Consider an NFL team that says the average weight of its defensive players is 315 pounds. A opposing team believes that their defensive players' average weight is lower than the 315 pounds they state. Consider that they take 15 defensive players as a sample and discover that the average weight of the players is 300 pounds, with an 8-pound sample standard deviation.

We have to create a suitable hypothesis test, draw conclusions at significance level 0.08, and then. Suppose that the weights are evenly distributed.

We know that,

Weights are normally distributed.

We are given μ = 315 , n= 15 , x = 300, s = 8, α = 0.08

The hypothesis are :

H₀ : μ = 315   v/s  H₁ : μ ≠ 315

The test statistic is given by,

z=x-μ/σ/√15

=300-315/8/√15

=-7.26

The critical value = z(α)  = z(0.04) = -1.75 and z(1-α)  = z(1-0.04)  = 1.75

Here calculated value of z > critical value of z

Therefore, we reject null hypothesis when hypothesis test, draw conclusions at significance level 0.08.
