First, find the area of each of the prisms sides
5 by 5.5 = 27.5
3 by 5.5 = 16.5
4 by 3 cut in half = 6 (theres 2 of thoses so 12)
4 by 5.5 = 22
Add up the products and the surface area is 78 units
Post brainliest if this helped :)
Answer:
x+3
Step-by-step explanation:
Answer:
Given :An Internet survey was e-mailed to 6977 subjects randomly selected from an online group involved with ears. There were 1337 surveys returned.
To Find : Use a 0.01 significance level to test the claim that the return rate is less than 20%.
Solution:
n = 6977
x = 1337
We will use one sample proportion test



We are given that the claim is the return rate is less than 20%.

Formula of test statistic = 
= 
= 
Refer the z table
P(z<-1.85)=0.0332
Significance level = 0.01=α
Since p value > α
So, we accept the null hypothesis .
So,the claim that the return rate is less than 20% is false.
<span>What percent of 600 is 12?
In order to get what percent of 600 is 12, we need to formulate the equation.
12 = ___ * 600
12 = 600P
P = 12 / 600
P = 0.02
Percentage must be in hundred. So multiply 0.02 by 100
= 0.02 * 100
= 2%
So, 2% of 600 is equal to 12.</span>
