Answer:
c) .22
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.
In this question:
Then

Answer:
its the steepness of two numbers on a graph - measures the steepness of the line. (what a slope is)
y=40x+10
Step-by-step explanation:
y=mx+b
Answer:
3 x 4 = 12, 12 divided by 2 ) x 1/2) = 6, 6 x 2 = 12(area of two triangles)
8 x 4 = 32
8 x 3 = 24
8 x 5 = 40
Let's add all the given areas:
12 + 32 + 24 + 40 = 108 m^2 is your answer.
