Answer:

$\$19,710$

Step-by-step explanation:

step 1

Find the volume of the composite figure

The volume of the composite figure is equal to the volume of the cube plus the volume of the square prism

$V=15^{3}+15^{2}(45)$

$V=13,500\ cm ^{3}$

step 2

Find the value of the figure

Multiply the volume by $1.46 per cubic centimeter

$13,500(1.46)=\$19,710$

A music buff wants to estimate the percentage of students at a midwestern university who believe that elvis is still alive. how

gulaghasi [49]

Since we are not given any information about the proportion, we will assume the sample proportion to be 0.50

so,
p = 0.50
The Error is 10% percentage point. This means that on either side of the population proportion the error is 5% so E = 0.05
z = 1.645 (Z value for 90% confidence interval)

The margin of error for population proportion is calculated as:

$E=z* \sqrt{ \frac{p(1-p)}{n} } \\ \\ 
 \frac{E}{z} = \sqrt{ \frac{p(1-p)}{n} } \\ \\ 
( \frac{E}{z} )^{2}= \frac{p(1-p)}{n} \\ \\ 
n= p(1-p)* (\frac{z}{E})^{2} \\ \\ 
n=271$

This means 271 students should be included in the sample
