Answer: A

Step-by-step explanation:

This is because 25%= 25/100, and that reduces to 1/4. Also, whenever it says something OF something, it means to multiply. In this case, 1/4 OF 1000= 1/4x1000= 250.

*Even though it seems that multiplying will just make the number bigger, when you multiply with a fraction, it actually gets smaller* For example 1/3 of 3= 1/3x3= 1

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

Answer:

They are equal.

Step-by-step explanation:

First, we can simplify the second equation by multiplying 7 times 6 and then 7 times 5 due to the distributive property.

$42+35 = 7(6+5)?\\42+35=(7 * 6)(7 * 5)\\42+35=42+35\\$

Therefore, using the distributive property, they are equal.
