Answer:
<h2><em><u>
First box and last box.</u></em></h2>
Step-by-step explanation:
<h2><em><u>
It is the first box.</u></em></h2>
Distribute 7 to the first number
7 * -3/4 = -21/4
-21/4 = 5 -1/4
Distribute 7 to the second number
7 * -3
= -21
Put the numbers together
<h2><em><u>
5 -1/4x -21 is the answer.</u></em></h2>
<h2><em><u>
It is also the last box.</u></em></h2>
They separated the parenthesis.
So it is still 7 * -3/4
and
7*-3.
Hope this helps,

Sum is the result of adding so
12 + x, but i don't see it as a option.
Answer:
We need a sample size of at least 719
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
How large a sample size is required to vary population mean within 0.30 seat of the sample mean with 95% confidence interval?
This is at least n, in which n is found when 
. So
Rouding up
We need a sample size of at least 719
since AC=1/2AB=6 THEREFORE C is the midpoint ofAB
