Based on the mean, standard deviation, and the graph, the indicated IQ score would be 115.
<h3>What is the indicated IQ score?</h3>
First, find the z value:
P(Z<z) = 1 - tail value
= 1 - 0.1587
= 0.8413
According to the z-value, this gives a value of:
z = 1
The indicated IQ score is:
= mean + z value z standard deviation
= 100 + 1 x 15
= 115

<u>First step</u>
Find the 10th year rate of loss that will make the average of loss over the 10 years to equal 38.0%.
Assume this rate is x;

x = 37%
<u>Second step - Survival rate</u>
The survival rate is calculated by;
= 1 - rate of loss
= 1 - 37%
= 63%

Answer:
The volume of the cylinder is 2.1 times the volume of the pyramid
Step-by-step explanation:
step 1
Find the volume of the pyramid
we know that
The volume of a right pyramid is equal to

where
B is the area of the base of pyramid
H is the height of the pyramid
we have

substitute

step 2
Find the volume of the right cylinder
we know that
The volume of right cylinder is equal to

where
B is the area of the base of cylinder
H is the height of the cylinder
we have

substitute

step 3
Compare the volumes
we know that
The area of the base both figures are congruent
Find the ratio of their volumes

substitute

Simplify


therefore
The volume of the cylinder is 2.1 times the volume of the pyramid
