Answer:
293 feet.
Step-by-step explanation:
Their track is 500 feet, and there are three sections. Add these sections(61+83+63=207) and subtract from the total(500-207=293)

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.
F(x) = ln (6-x); find the domain.
The domain of the "ln" function is (0, infinity), or "x is greater than zero."
Thus, the domain of the given function is "(6-x) is greater than zero."
Solve this: 6-x > 0. Add x to both sides. Then 6 > x, or x < 6 (answer)
