Adjacent and hypotenuse are given so use cosine.
Cos28= 11/x
12.46 is your answer (I rounded)
Answer:
0.44ft/hr
Step-by-step explanation:
Given parameters:
Quantity of rainfall = 8inches
1ft = 12inches
so;
= 0.67ft
Time = hr
Unknown:
Rate of rainfall expressed in ft/hr = ?
Solution:
The rate of the rainfall is given as;
Rate =
Rate = = 0.44ft/hr
Answer:
And we want this probability:
And using the normal standard distribution or excel we got:
And the best option would be:
D 0.0233
Step-by-step explanation:
For this case we have the following parameters:
And we select a sample size of n=13. And we want to find this probability:
We can assume that the distribution for this case is normal and then we can use the z score formula given by:
And if we replace the data given we got:
And we want this probability:
And using the normal standard distribution or excel we got:
And the best option would be:
D 0.0233
