Answer:
Option D. A student who studies 0 hours can expect to score about a 60 on the test
Step-by-step explanation:
we know that
The y-intercept is the value of the y-coordinate when the value of the x-coordinate is equal to zero
In this problem
The x-coordinate represent the hours spent studying
The y-coordinate represent the Test score
so
For x=0, y=60
That means
A student who studies 0 hours can expect to score about a 60 on the test
Answer: a. $128.125
Step-by-step explanation:
The standard error of the mean is given by :
, where 
= population standard deviation , n= sample size.
Given: 
n= 256
Then, the standard error of the mean:-
Hence, option a. is correct.
For the first question you just need to add up all the sides. so first add all the x numbers and then add all the plain numbers.
a perimeter is the total length around the shape.
The (assumed) answer to this question is no, his mean is $88.67 and his average mean he chose was $92. (Answer inconclusive due to asked question failing to repeat desired answer.)
The answer to #4 is A equilateral because all the sides are the same. the sides are equal.
# 7 would be c, 45 you have to make sure the sum is 180 #8 is B the same goes for that on fill in x and y. #11 isD And # 12 is c the sum must be 180.<span />
