Answer:
first one is c becuase of the way i added and then subtactied
second one is a i divide then ad sub and ad it again bye 3
srry if i am wrong
brainlyest would be nice ( ;
Step-by-step explanatnation
We are given the following in the question:
Sample size, n = 200
\hat{p} = 65\% = 0.65
Margin of error =
\pm 6.75\% = \pm 0.0675
\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}
\hat{p}\pm \text{Margin of error}
Putting values:
(0.65 \pm 0.0675)\\=(0.5825,0.7175)
D=distance traveled one way
t=d/s
d/20 + d/30 = 12
3d+2d=60(20)
5d=720
d=720/5 = 144 mi one way
144/20 = 7.2 hrs at 20 mph
144/30 = 4.8 hrs at 30 mph
