A= 50.27 because the formula is pi times radius squared
C= 24.13 because the formula is 2 times pi times radius
Answer:
-6
Step-by-step explanation:
y=-1/3(12)-2
=(-1/3x12/1)-2
=-4-2
y=-6
The general formula for the margin of error would be:
z * √[p (1-p) ÷ n]
where:
z = values for selected confidence level
p = sample proportion
n = sample size
Since the confidence level is not given, we can only solve for the
<span>√[p (1-p) ÷ n] part.
</span>
p = 44/70
n = 70
√[44/70 (1 - (44/70) ÷ 70]
√[0.6286 (0.3714)] ÷ 70
√0.2335 ÷ 70
√0.0033357 = 0.05775 or 0.058 Choice B.
Where is the diagram? How do we answer without it?
Answer:
68.1 units²
Step-by-step explanation:
Start by finding the area of the rectangle...
Then, find the area of the semicircle...
Now, add the two to get...
54+14.1=68.1
