A. -8

Step-by-step explanation:

Answer:

-8

Step-by-step explanation:

When compared to a normal distribution, a t-distribution with a small degrees of freedom has heavier tails, indicating a higher probability of extreme values. As the degrees of freedom increase, the shape of the t-distribution approaches that of a normal distribution.

The shape of a t-distribution with a small degrees of freedom (df) differs from that of a normal distribution. The first paragraph provides a summary of the answer, and the second paragraph explains the details of the comparison.

A t-distribution with a small degrees of freedom has a shape that is similar to a normal distribution, but with heavier tails. As the degrees of freedom decrease, the t-distribution becomes more spread out and has a higher probability of extreme values compared to a normal distribution.

The tails of the t-distribution are fatter or thicker than those of a normal distribution. This means that the t-distribution has a higher probability of extreme values, making it more likely to observe values far away from the mean. In contrast, the normal distribution has thinner tails, indicating a lower probability of extreme values and a higher concentration of data around the mean.

The shape of the t-distribution approaches that of a normal distribution as the degrees of freedom increase. When the degrees of freedom are large (typically above 30), the t-distribution becomes very similar to a normal distribution, and the differences between them become negligible.

The t-distribution is widely used in statistical inference, especially in situations where the sample size is small or when the population standard deviation is unknown. It provides a more appropriate distribution for estimating population parameters when the underlying data exhibit variability.

In summary, compared to a normal distribution, a t-distribution with a small degrees of freedom has heavier tails, indicating a higher probability of extreme values. As the degrees of freedom increase, the shape of the t-distribution approaches that of a normal distribution.

The answer is explained below

Step-by-step explanation:

The location of point A = (-5, -1) and point B = (4, 1).

To find the coordinate of the point that divides a line segment PQ with point P at \((x_1,y_1)\) and point Q at \((x_2,y_2)\) in the proportion a:b, we use the formula for the x and y coordinates:

\(x-coordinate:\\\frac{a}{a+b}(x_2-x_1)+x_1 \\\\While \ for\ y-coordinate:\\\frac{a}{a+b}(y_2-y_1)+y_1\)

P is One-fourth the length of the line segment from A to B, Therefore AB is divided in the ratio 1:4. The location of point A = (-5, -1) and point B = (4, 1).Therefore:

\(x-coordinate:\\\frac{1}{1+3}(4-(-5))+(-5)=\frac{1}{4}(9)-5=-\frac{11}{4} \\\\While \ for\ y-coordinate:\\\frac{1}{1+3}(1-(-1))+(-1)=\frac{1}{4}(2)-1=\frac{-1}{2}\)

Therefore the coordinate of P is (-11/4, -1/2)

Answer:

the coordinate of P is (-11/4, -1/2)

x= -11/4

y= -1/2

The key approach is to analyze the relationship between the number of solutions to the equation Ax = 0 and the result of Gaussian elimination.

Since the columns of A are linearly dependent, there exist scalars c1, c2, ..., cn (not all zero) such that c1a1 + c2a2 + ... + cnan = 0, where ai represents the columns of A. We can rewrite this equation as a system of linear equations: Ax = 0, where x = [c1, c2, ..., cn]T is a column vector.

The linear dependence of the columns implies that the system Ax = 0 has infinitely many solutions, as we can always find non-trivial combinations of the columns that yield the zero vector.

Now, let's consider applying Gaussian elimination to matrix A. Gaussian elimination transforms the matrix into reduced row echelon form. If the resulting matrix has at least one row of all zeros, it means that there is at least one free variable in the system Ax = 0. This indicates that the system has infinitely many solutions.

Since the system Ax = 0 has infinitely many solutions, and the result of Gaussian elimination with a row of all zeros indicates linear dependence, it follows that the rows of A must also be linearly dependent. Therefore, the linear dependence of the columns implies the linear dependence of the rows.

Step-by-step explanation:

Step 1:  Find the amount Elmer's funds decreased after purchasing the rabbits:

Let x represent Elmer's funds.

Since Elmer bought five rabbits for $10 each, he lost $10 5 times.

x - (10 * 5)

x - 50

Thus, Elmer lost (spent) $50 for the 5 rabbits.

Step 2:  Find the amount Elmer's funds decreased after purchasing the  cupboards:

Since Elmer bought four cupboards for $70 each, he lost $70 4 times:

x - (50 + (70 * 4))

x - (50 + 280)

x - 330

Thus, after purchasing the rabbits and cupboards, Elmer lost $330.

Step 3:  Find the amount Elmer's funds increased after finding the twenty-dollar bill:

Since Elmer found a twenty-dollar bill, he gained $20

x - (330 + 20)

x - 310

Step 4:  Find the amount Elmer's funds increased after returning one rabbit:

Since Elmer returned one rabbit, he gained $10:

x - (310 + 10)

x - 300

Thus, Elmer's funds changed totally by -$300.

Putting all the information together, we have:

x - 10 - 10 - 10 - 10 - 10 - 70 - 70 - 70 - 70 + 20 + 10

x - 50 - 280 + 30

x - 330 + 30

x - $300

Answer:

Step-by-step explanation:

320 = 16x

Our objective here is to isolate the variable (x) using inverse operations

First we want to get rid of 16

16x is the same as 16 times x( which is multiplication)

The inverse of multiplication is division so to get rid of the 16 we divide by 16 ( but note: whatever you do to one side you must do to the other ) so we divide both sides by 16

320/16=20

16x/16 = x

We would be left with x = 20

This meaning that they would need 20 first grade classes

Answer:

The school will need 20 first grade classes

Step-by-step explanation:

So think about it. There are 320 first grade students and each class can have 16 students which represents the equation 16x=320

All you need to do is solve the equation 16x=320

The equation is multplication. To undo multiplication you need to do division

So, x=320/16

x=20

So overall, your awnser is 20.

The greatest amount of gold that can be in the vault is 0 ounces.

To find the greatest amount of gold that can be in the vault, we need to determine the maximum number of 8 ounce tablets that can be stored.

If the total weight of gold and silver is 130 ounces, we can subtract the weight of the silver from the total to get the weight of gold.

Since each silver tablet weighs 5 ounces, the weight of silver can be found by dividing the total weight by 5.

130 ounces ÷ 5 ounces = 26 tablets of silver

Now, to find the maximum number of 8 ounce tablets that can be stored, we divide the weight of gold by 8.

130 ounces - (26 tablets × 5 ounces) = 130 ounces - 130 ounces = 0 ounces of gold

Therefore, the greatest amount of gold that can be in the vault is 0 ounces.

Step-by-step explanation:

To model the amount of money the florist earns for each delivery, we can break it down into the different components involved.

This can be represented by the term "+10".

This can be represented by the term "+2x", where x represents the number of miles.

This can be represented by the term - ( 0.50x + 5 )

The composite function g(h(8)) when evaluated is 94.

From the question, we have the following parameters that can be used in our computation:

g(a) = 4a - 2

h(a) = 3a

To find g(h(8)), we need to first evaluate h(8), and then plug that result into g(a) and simplify.

h(a) is defined as 3a, so h(8) = 3(8) = 24.

Now we can plug in 24 for a in g(a) and simplify:

g(a) = 4a - 2

g(h(8)) = g(24) = 4(24) - 2 = 94

Therefore, g(h(8)) = 94.

If we denote the probability of hitting a bullseye on a dartboard with radius 12 inches as a function of the size of the bullseye, we can refer to this function as PS.

The function PS represents the probability of hitting the bullseye and is dependent on the size of the bullseye. The larger the bullseye, the higher the probability of hitting it, and vice versa. By adjusting the size of the bullseye, we can determine the corresponding probability of hitting it using the function PS.

It's important to note that without specific information about the relationship between the bullseye size and the probability, it's not possible to provide a specific mathematical expression or further details about the PS function.

There are 4845 different ways to select 16 questions out of a total of 20 questions on the exam.

To determine the number of different ways you can select 16 questions out of a total of 20 questions, we can use the concept of combinations.

In this case, we want to select 16 questions from a set of 20 questions, and the order in which we select them doesn't matter. This scenario can be represented by the combination formula.

The formula for combinations is given by:

C(n, k) = n! / (k!(n-k)!)

Where:

n is the total number of items in the set (20 questions)

k is the number of items to be selected (16 questions)

! denotes the factorial operation

Using the combination formula, we can calculate the number of different ways to select the questions:

C(20, 16) = 20! / (16!(20-16)!)

= 20! / (16!4!)

= (20 * 19 * 18 * 17) / (4 * 3 * 2 * 1)
