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.
Answer:
Step-by-step explanation:
0.03550295857
Area = 285mm²
Length = 18mm
We can find the width by dividing the area by the length.
approximately.
2(18) + 2(15.8) = 67.6mm
It will be will 86 first u add the 2 numbers together and then u get 94 then u do 180 minus 180 and u get 86
