D 17x
This is because you’re not adding or subtracting months from your 17 letters. So cross A and C out. And you’re not dividing the number of letters by months. So cross B out. You’re left with D and this is correct because 17 letters EACH month. EACH is telling us that you multiply 17 and x.

Answer:
The distance around Earth at the Equator is about 24,900 miles
Step-by-step explanation:
Let
x -----> the distance around Earth at the Equator
we know that
The linear equation that represent this scenario is
Solve for x
Subtract 5,300 both sides
Divide by 3 both sides
Rewrite
therefore
The distance around Earth at the Equator is about 24,900 miles
Answer:
(0.4958, 0.7422)
Step-by-step explanation:
Let p be the true proportion of water specimens that contain detectable levels of lead. The point estimate for p is . The estimated standard deviation is given by . Because we have a large sample, the 90% confidence interval for p is given by where is the value that satisfies that above this and under the standard normal density there is an area of 0.05. So, the confidence interval is , i.e., (0.4958, 0.7422).
Answer:
C.
Step-by-step explanation:
We are given are odd which means:
We can tell if a function,, is even if .
We can tell if a function,, is odd if .
So let's test your I,II,III.
We will be replacing x with -x to find out.
I.
So is odd.
II
So is odd.
III
So is even.
So I and II are odd and III is even.
C. is the answer.
