Step-by-step explanation:
slope = change of y/ change of x
here, 7-1 / -2-4 = 6/-6 = -1

Step-by-step explanation:
Answer:
Mean 24, standard error 0.8
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation, also called standard error 
In this problem, we have that:

What are the mean and the standard error of the sample mean?
By the Central Limit Theorem, mean 24 and standard error 
Answer:
Biography= 8/24= 1/3
Science Fiction= 6/24= 1/4
Step-by-step explanation:
The probability for biography is (biography/total amount of books.)
8/24= 1/3
The probability for science fiction is (science fiction/ total amount of books.)
6/24= 1/4
Answer:
A. { }
Step-by-step explanation:
Absolute value cannot be less than zero.
-4 < 0
There is no solution for x, ∈, R.
Hope this helps.
