Answer: t = 77
Step-by-step explanation:
To solve for t, we will simplify and isolate the variable.
Given:
65 = t - 5 - 7
Combine like terms:
65 = t - 12
Add 12 to both sides of the equation:
77 = t
Answer:
Your annswer is b
Step-by-step explanation: because it is least than all of the others
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.
