Answer:
C or D most likely C
Step-by-step explanation:
Definitely not A or B they don’t matter or make sense.. C makes more sense because it’s directly hit with heat needed to evaporate, for D to be lower it’ll take longer if at all to evaporate because it’s colder closer to the sea floor

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.
Answer:
Equation: w = (1/8) c
c at w = 44 minutes is 352 minutes
Explanation:
We are given that:
1- Time taken to cycle from library to mall is c minutes
2- Time taken to walk from library to mall is w minutes
3- Time taken to walk = 1/8 time taken to cylcle
Therefore:
w = (1/8) c
Now, we want to find c if w = 44 minutes
All we do is substitute with the w in the equation and get c as follows:
w = (1/8) c
44 = (1/8) c
c = 44*8 = 352 minutes
