Answer:
3,765.2
Step-by-step explanation:
Move the decimal to the tenths place.
Answer: 95% confidence interval would be (175.04,194.96).
Step-by-step explanation:
Since we have given that
Mean = 185 mg
Standard deviation = 17.6 mg
At 95% confidence level, z = 1.96
So, Interval would be
Hence, 95% confidence interval would be (175.04,194.96).
Answer:
And if we solve for a we got
Eighty percent of the time, it takes more than 8.526 how many minutes to find a parking space
Step-by-step explanation:
Let X the random variable that represent the lenght of time it takes to find a parking space of a population, and for this case we know the distribution for X is given by:
Where and
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
We want to find a value who accumulate 0.80 of the area on the left and 0.2 of the area on the right it's z=0.842.
If we use condition (b) from previous we have this:
Using this formula we have:
And if we solve for a we got
Eighty percent of the time, it takes more than 8.526 how many minutes to find a parking space
Answer:
1692.5 ft³
Step-by-step explanation:
Thank you for giving the equation which would help me in solving. We know that our h which is the height is 11 ft. We have to find what the radius. Radius is the have of the diameter. In the figure, the 14 ft is the diameter. So in order to find the radius, we would divide it by 2.
14 ft ÷ 2 = 7 ft
h = 11 ft
r = 7 ft
Now plug it in the equation.
In the equation you have this sign above. Remember this is the pi sign which is 3.14.
V = 3.14r²h
V = 3.14<u>(7)</u><u>²</u> × 11
V = <u>3.14(49)</u> × 11
V = <u>153.86 × 11</u>
V = 1692.5 ft³
Hope this helps, thank you :) !!
