Answer:
0.7422 = 74.22% of scores are above 74.
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:

Calculate the proportion of scores above 74.
This is 1 subtracted by the pvalue of Z when X = 74. So



has a pvalue of 0.2578
So 1-0.2578 = 0.7422 = 74.22% of scores are above 74.
Answer:
1.425.
Step-by-step explanation:
1 .425 is the only one which can be written as a fraction ( 1425/ 1000).
π is a non repeating decimal which goes on without bounds.
So is √50 (try entering it on your calculator).
√-4 : there is no real number whose square root is negative.
I would say its d
the pentagon has no right angles or acute angles (at least thats what it looks like) so i believe it is has all obtuse angles.
