Answer: Area of Yellow part is 5.365046
Step-by-step explanation:
Figure show that length of square is 5 ft and diameter of circle is also, 5 ft.
Here, Red part + Yellow part = Entire square of length of 5ft
Area of red part is area of circle =
=
= 19.634954
Area of Entire square of length of 5ft = 5x5 = 25
Therefore, Area of Yellow part is 25-19.634954=5.365046

Answer:
0.73% of the scores are greater than 2317.
14.46% of the scores are less than 1190.
38.23% of the scores are between 1351 and 1673.
Step-by-step explanation:
Problems of normally distributed samples can be 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 the percentage of scores greater than 2317.
This is 1 subtracted by the pvalue of Z when X = 2317. So:
has a pvalue of 0.9927.
So 1-0.9927 = 0.0073 = 0.73% of the scores are greater than 2317.
Find the percentage of scores less than 1190.
This is the pvalue of Z when X = 1190. So:
has a pvalue of 0.1446.
So 14.46% of the scores are less than 1190.
Find the percentage of scores between 1351 and 1673.
This is the pvalue of Z when X = 1673 subtracted by the pvalue of Z when X = 1351. So
X = 1673
has a pvalue of 0.67
X = 1351
has a pvalue of 0.2877
So 0.67-0.2877 = 0.3823 = 38.23% of the scores are between 1351 and 1673.
