Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.

Answer:
C. p(x) = 5x - 12.
Step-by-step explanation:
p(x) = 8x - (3x + 12) (Note you have to put the 3x+12 in parentheses).
p(x) = 8x - 3x - 12
p(x) = 5x - 12
Answer:
The area of the circle is 314 in^2.
Step-by-step explanation:
10 inches is the radius.
The formula for the area of a circle is pi times radius squared.
So your equation would be: 
10^2 = 100
Then you do 
or 3.14 times 10 = 314.1592654 or just 314.

The perimeter of the triangle is: 4x+9
Step-by-step explanation:
Perimeter is the measurement of boundary of any closed figure.
Given
s1 = x+4
s2 = x+8
s3 = 2x-3
So, the perimeter will be the sum of all three sides
Hence,
The perimeter of the triangle is: 4x+9
