It also allows us to test the statistical significance of the coefficients and determine the strength of the relationship between athletic success and applications.

To determine the effects of collegiate athletic performance on applicants, we can use measures such as team win-loss records, conference championships, national championships, and individual athlete awards such as All-American honors. Timing is a crucial factor to consider as changes in application numbers may not be immediate and could occur over several years. We should also control for other factors such as academic reputation, location, size, and type of college.
To estimate the effects of athletic success on the percentage change in applications, we can use a multiple regression equation. The equation can be written as:
ΔApplications = β0 + β1Win-Loss Record + β2Conference Championships + β3National Championships + β4All-American Honors + β5Academic Reputation + β6Location + β7Size + β8Type + ε
Here, ΔApplications represents the percentage change in applications from year to year. The coefficients β1-β4 represent the effects of athletic success on applications, while β5-β8 control for other factors. ε is the error term.
We can estimate this equation using statistical software such as Stata or R. We would choose this method because it allows us to estimate the effects of multiple variables simultaneously while controlling for other factors that may influence the results.

Yes, the answer is D) 9. Robinson Crusoe is observing that adjacent numbers in the sequence are divisible by each other.

To see why, consider the positive whole numbers less than 11 that are divisible by one another. These are the figures:

1, 2, 4, 8

Each of these numbers can be divided by the number that comes before it in the sequence. For example, two is divisible by one, four is divisible by two, and eight is divisible by four.

So, if Friday wrote this sequence in the sand, he could only write four numbers next to each other. He would have to repeat the sequence to write down more numbers.

For example, he could write down the sequence twice and get the following:

1, 2, 4, 8, 1, 2, 4, 8

This sequence has 8 numbers, and writing down the sequence a third time would give him 9 numbers:

1, 2, 4, 8, 1, 2, 4, 8, 1, 2, 4, 8

The principal in terms of Simple Interest, Time, and Rate can be expressed as p=(i×100)/(r×t).

Whenever a loan is given to a person it is given for some specific amount of time at a specific rate of interest which is to be paid along with the principal amount. Simple Interest is the method of calculating the interest amount on a loan given for a specific period.

It involves the multiplication of the principal amount, rate of interest, and the time for which the loan is given divided by 100.

Here Simple interest is denoted by i, time in years is denoted by t, the principal is denoted by p, and the rate of interest is denoted by r.

The formula of simple Interest is given by:

Simple interest = (Principal×Rate×Time)/100

i=(p×r×t)/100

Now principal can be denoted as:

p=(i×100)/(r×t)

Thus, the Principal in terms of Simple Interest, Time, and Rate can be expressed as p=(i×100)/(r×t).

There are 55 ways to form a train consisting of tank cars, boxcars, and flatcars by using concept of combinations.

If there are t tank cars, b boxcars, and f flatcars in the train yard, then the number of ways to form a train by selecting some of these cars is the same as the number of ways to distribute n = t + b + f identical objects into three distinct boxes, such that each box may receive any number of objects (including zero). The solution is given by the combination formula:

C(n + k - 1, k - 1)

where k is the number of boxes (in this case, k = 3). Therefore, the number of ways to form a train from t tank cars, b boxcars, and f flatcars is:

C(t + b + f + 3 - 1, 3 - 1) = C(t + b + f + 2, 2) = (t + b + f + 2)! / ((t + b + f)! * 2!)

There are 4 tank cars, 3 boxcars, and 2 flatcars in the train yard, then the number of ways to form a train is:

You simply just have to add them because they have the same root and are both cubed as well as the same variable "x".

The polynomial in the factored form is x(x + 6)(x - 6). The zeroes of the polynomial are x = 0, x = -6, and x = 6.

A polynomial is a mathematical equation that solely uses the operations and non-negative integer exponentiation of variables.

To factor x³ - 36x, we can first factor out an x:

x(x² - 36)

Then, we can use the difference of squares formula to factor the expression in the parentheses:

x(x + 6)(x - 6)

This gives us the factored form of the polynomial: x(x + 6)(x - 6).

To find the zeros of the polynomial, we can set each factor equal to zero and solve for x:

x = 0, x + 6 = 0, x - 6 = 0

So the zeros of the polynomial are x = 0, x = -6, and x = 6.

Therefore, the factored form is  x(x + 6)(x - 6). And the zeroes are x = 0, x = -6, and x = 6.

The equation of the hyperbola for the cross section of the cooling tower is x²/8100 - y²/9506.25 = 1.

We must take into account its characteristics in order to formulate the hyperbola's equation for the cooling tower's cross section.

Since the origin serves as the hyperbola's centre, its coordinates are (0, 0).

The left/right opening of the hyperbola indicates that the primary axis is horizontal.

The cooling tower's smallest diameter is 180 metres, which is the same length as the minor axis.

The primary axis' 195 m length and the diameter at its highest point are matched.

The hyperbola's highest point is 80 metres above the centre.

These characteristics allow us to write the hyperbola's equation in standard form:

(x - h)²/a² - (y - k)²/b² = 1

Where (h, k) represents the center of the hyperbola.

Substituting the given values:

Center: (h, k) = (0, 0)

Minor axis: 2a = 180 m, so a = 90 m

Major axis: 2b = 195 m, so b = 97.5 m

Vertical shift: c = 80 m

Now we can write the equation of the hyperbola:

x²/90² - y²/97.5² = 1

x²/8100 - y²/9506.25 = 1

\( \boxed {\tt x = \cfrac{1}{3}} \)

Actual answer :-

\(\boxed{\tt \: 3 \times \boxed{\cfrac{1}{3}} = 1}\)

Step-by-step explanation:

Given equation :-

\(\sf 3 \times ? = 1\)

(Note: I wrote "?" instead of "blank".)

We need to find the value of the blank on this equation.

Solution:-

To solve Further let's us assume that the value of the blank be \(x\).

So, blank = \(x\)

The equation will be . . .

\(\sf \longmapsto3 \times x = 1\)

Let's solve out this equation !

\(\sf \implies3 \times x = 1\)

Multiply 3 and x on the LHS :-

\(\sf \implies3 x = 1\)

Hence the new equation would be 3\(x\)=1.

Now, Divide both sides by 3 :-

\(\sf \implies \: \cfrac{3x}{3} = \cfrac{1}{3} \)

Simplify this equation :-

Cancel 3 and 3 on the LHS, Leave \(x\) . 1/3 can't be cancelled.

\(\sf \implies \: \cfrac{ \cancel3}{ \cancel3x} = \cfrac{1}{3} \)

\(\sf \implies1x = \cfrac{1}{3} \)

As we know that x = 1x So,

\(\sf \implies \: x = \cfrac{1}{3} \)

This equation can't be simplified more.

Hence, the value of \(x\) would be 1/3.

Now,Put the value of \(x\) (1/3) on the given equation:-

\(\sf \implies \: 3 \times \: \cfrac{1}{3} \: = 1\)

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

The number of batch recipe calls for 1 / 2 lb of flour = 1 batch

And to calculate the number of batches , we use

The number of batch recipe calls for 1 lb of flour will be

1 / 2 lb of flours = 1 batch

Multiplying by 2 on both sides , we find the number of batches for 1 lb of flour

Therefore , 1 / 2 x 2 = 1 x 2

1 lb of flour = 2 batches

3 / 4 lb of flour is 1 x 3 / 4 = 2 x 3 / 4

                                          = 3 / 2 batches

                                          = 1.5 batches

1 / 4 lb of flour is 1 x 1 / 4 = 2 x 1 / 4

                                        = 1 / 2 batches

                                        = 0.5 batch

y = -7t cos(t) - 7t is the solution of the equation dy = y + 7t² sin(t) as it satisfies the differential equation and the initial condition.

To verify that y = -7t cos(t) - 7t is a solution of the initial-value problem dy/dt = y + 7t² sin(t) with y(π) = 0, we need to check that y satisfies the differential equation and the initial condition.

First, we can calculate the derivative of y with respect to t as follows:

dy/dt = d/dt (-7t cos(t) - 7t)
= -7 cos(t) - 7 + (-7t)(-sin(t))
= -7(cos(t) + t sin(t))

Next, we can substitute y and dy/dt into the differential equation and simplify:

dy/dt = y + 7t² sin(t)
-7(cos(t) + t sin(t)) = (-7t cos(t) - 7t) + 7t² sin(t)
-7 cos(t) - 7 + 7t sin(t) = -7t cos(t) - 7t + 7t² sin(t)
-7 cos(t) - 7 = -7t cos(t) - 7t + 7t² sin(t) - 7t sin(t)
-7 cos(t) - 7 = -7t(cos(t) + sin(t)) + 7t² sin(t)

This equation is true for all t, so we have verified that y = -7t cos(t) - 7t is a solution of the differential equation.

Finally, we need to check the initial condition. Since y(π) = -7π cos(π) - 7π = 0, the initial condition is satisfied.

Therefore, we have confirmed that y = -7t cos(t) - 7t is a solution of the initial-value problem dy/dt = y + 7t²sin(t) with y(π) = 0.
