Answer:
30% and added to/subtracted from
Step-by-step explanation:
The value of p from the given equation is 136.
The given equation is p/4 - 15 = 19.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is solved as follows:
Transpose -15 to other side of the given equation
That is, p/4 = 19+15
⇒ p/4 = 34
Cross multiply 4 to 34
We get p = 34 × 4
⇒ p = 136
Therefore, the value of p from the given equation is 136.

Answer:
(C) They are the same
Step-by-step explanation:
The coefficient of variation CV is given by the following formula:
In which 
is the standard deviation and 
is the mean.
Bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds
This means that 
.
So his coefficient of variation is
Mary's weight has a mean of 125 pounds with a standard deviation of 10 pounds.
This means that 
So her coefficient of variation is
They have the same coefficient of variation, so the correct answer is.
(C) They are the same
Its 8.7 because 1 is lower than 6 so you add 7.
