Answer:
Upper P60 = 212.8
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Find Upper P 60, the score which separates the lower 60% from the top 40%.
This is the value of X when Z has a pvalue of 0.6. So it is X when Z = 0.255.
Upper P60 = 212.8
Answer:
The following are the answers:
a = 1
b = 6
c = -55
Step-by-step explanation:
When looking for a, b, and c in a quadratic, you are looking at coefficients only. The coefficient of x^2, which in this case is 1, is a. The coefficient of x, which in this case is 6, is b. Lastly, the constant at the end, which in this case is -55, is c.
108/12=9
(You have to divide because you are seeing how many times 12 will go into 108 square feet)
The width of the door is 9 feet!
You can check your answer by multiplying 12 feet times 9 feet.
Your answer will be 108 ft squared! :)
So, the width of the door is 9 feet.
Hope I helped! :)
If you’re looking for a equation it could be “ 24c + 15 = 687 “
The sequence is 4, 5, 6, 7, 8, ..... The pattern is: Each term is (the term before it) plus (1).
