Tony separates a number of paintbrushes, x, into 3 equally sized groups. He claims that this is the same as making a group 1/3 t

DochEvi [55]

Answer:

Size of each group = $\frac{x}{3}$

Step-by-step explanation:

Total number of paint brushes = x

Since each the three groups are equally sized, to get the number of paintbrushes in a group, we will have to divide the total number of paint brushes by 3

∴ We have, number of paint brushes in a group = $\frac{Total number of paintbrushes}{3}\\$

= $\frac{x}{3}$

this is also the same thing as saying $\frac{1}{3}$ × $\frac{x}{1}$

This shows that the size of the new group is the same as $\frac{1}{3}$ the size of the original group

28)A regression equation is obtained for a collection of paired data. It is found that the total variation is 24.488, the explai

Doss [256]

Answer: The coefficient of determination = 0.6291

Step-by-step explanation:

Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.

The coefficient of determination is computed as:

$\text{ coefficient of determination} =\frac{\text{explained variation }}{\text{total variation}}$

Substituting given values, we get

$\text{coefficient of determination} =\frac{15.405}{24.488}$

$=0.6291$

Therefore, the coefficient of determination = 0.6291

irina1246 [14]

Answer:

Option B.

Step-by-step explanation:

The given expression is

$\dfrac{10x^2-32}{4}$

We need to find the simplified form of given expression.

Taking out GCF from the numerator.

$\dfrac{2(5x^2-16)}{4}$

Cancel out common factors.

$\dfrac{5x^2-16}{2}$

The expression $\dfrac{5x^2-16}{2}$ is the simplified form of given expression.

Therefore, the correct option is B.

What is the solution set of -9x

klio [65]

Answer:

B. x≥-3

Step-by-step explanation:

To solve this problem, first you have to isolate it one one side of the equation.

First, multiply -1 from both sides.

(-9x)(-1)≥27(-1)

Solve.

27*-1=-27

9x≥-27

Next, divide by 9 from both sides.

9x/9≥-27/9

Then, solve.

-27/9=-3

Therefore, the correct answer is x≥-3.
