7 1/5th is the anwser but thats easy your just being lazy i think
Answer:
119.2
Step-by-step explanation:
Given the following :
Mean (m) = 100 years
Standard deviation (sd) = 15 years
closest to the age of a Galápagos Islands giant tortoise at the 90th percentile of the
distribution?
Obtain the Zscore for 90th percentile (0.90) on the z table = 1.28
Zscore = (X - mean) / standard deviation
1.28 = (X - 100) / 15
1.28 × 15 = X - 100
19.2 = X - 100
19.2 + 100 = X
X = 119.2
A line graph. The amount of time to do those things relates more to a line graph
D. x=3
I don't really know how to explain it other than the only points on the line are sitting at the x=3 and y=anything
A suitable calculator shows the score of
46.0 separates the bottom 26% from the top 74%.
