Answer:
62.5%
Step-by-step explanation:
(56 - 62) / 4 = -1.5 z score = 0.0668
(64 - 62) / 4 = 0.5 z score = 0.6915
0.6915 - 0.0668 = 0.6247
Rounded this becomes 62.5%
Answer:
$200
Step-by-step explanation:
You divide to find the answer
50 divided by 0.25
and you will get 200.
So $50 is 25% of 200
For a double check do 50/200
50/200 = 25/100
25/100 = 1/4
1/4 = 0.25
0.25 = 25%
So the final answer is 200.
Hope it helped! My answer is expert verified.
Answer: The confidence interval would be (0.2928,0.3672).
Step-by-step explanation:
Since we have given that
Total number of vehicles = 432
Number of SUVs sold = 142
So, it becomes,

At 90% confidence interval,
z = 1.645
So, the confidence interval would be

Hence, the confidence interval would be (0.2928,0.3672).
The first side is 71.5
the extended side is 107.25
i am pretty sure about this
The distance (d) traveled by the airplane is the product of multiplying the speed (s) and the trip took (h). The equation is shown below,
d = s x h
Substitute the known values to the equation,
637.5 miles = (150 mile/ hour) x h
Manipulating the equation,
h = (637.5 miles) / (150 mile/ hr)
h is equal to 4.25 hours.
