Answer:
H: 0, 1, 2, 3, 4, 5
plumber 1: 20, 70, 110, 160, 210, 260
plumber 2: 0, 60, 120, 180, 240, 300
plumber 1: C = 50h + 20
plumber 2: C = 60h
Answer:
The result=16
Step-by-step explanation:
The result of 32% of 50 can be expressed as;
R=P×O
where;
R=result
P=percentage
O=original value
In our case;
R=unknown
P=32 %
O=50
replacing;
R=32 % of 50
R=32%×50
R=(32/100)×50
R=0.32×5=16
The result=16
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.
