5280 feet in 1 mile
3600 seconds in an hour
58(5280) / 3600 = 306240/3600 = 85.06 ft per sec or if u need it rounded, it is 85.1
Answer:
V≈2412.74
Step-by-step explanation:
To find the width, divide the area by the length.
Width = 375 / 25
Width = 15 feet.
Answer:
s = 28.09 m/s
Step-by-step explanation:
Given that,
The equation that gives the height of the largest ocean waves when the wind speed is s knots is given by :

We need to find the wind speed if the largest waves are 15 feet high.
Put h = 15 feet in the above equation as follows :

So, the speed of the wind is 28.09 m/s.
Answer:
Step-by-step explanation:
From the given information;
The null hypothesis & alternative hypothesis:

The test statistics can be computed as:




The p-value = 2(Z > 2.11) since this is a two-tailed test
The p-value = 2( 1 - Z < 2.11)
The p-value = 2 (1 -0.9826)
The p-value = 2 (0.0174)
The p-value = 0.0348
Decision Rule: To reject the
if the p-value is less than 
Conclusion: We fail to reject
and conclude that the population mean = 2, thus the machine is properly adjusted.
