Answer:
77.4% probability that a data value is between 36 and 41
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 question, we have that:
What is the probability that a data value is between 36 and 41?
This is the pvalue of Z when X = 41 subtracted by the pvalue of Z when X = 36.
X = 41
has a pvalue of 0.933
X = 36
has a pvalue of 0.159
0.933 - 0.159 = 0.774
77.4% probability that a data value is between 36 and 41
To get the answer you have to fill in the 14 for r because that is the radius. Then multiply 14 by it self to get 196 then multiply that by pie to get your answer of 615.75216.
So the answer is 615.75216
Rate of change=(change in cookies)/(change in time)
We are told that change in cookies is 12 and change in time is 1, so the rate of change is 12/1=12 cookies/hour or
12 cookies per hour.
Answer:
what is the multiple choice how old is arif
Step-by-step explanation:
Find the area of the rectangular patio.
A = lw
A = 15 * 5
A = 75
Now find the area of each square tile:
A = s^2
A = 1^2
A = 1
Divide this by 75:
75 / 1 = 75
So he needs 75 square tiles to cover the patio.
