(1 point) The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with a mean of 127 and standard deviation of 10. Calculate the z-scores for the male systolic blood pressures 100 and 150 millimeters. (a) 100 millimeters z-score = (b) 150 millimeters z-score = (c) Kyle's doctor told him that the z-score for his systolic blood pressure is 1.75. Which of the following is the best interpretation of his score? Kyle's systolic blood pressure is 1.75 standard deviations above the average systolic blood pressure for men. Kyle's systolic blood pressure is 1.75 times the average blood pressure of men his age. Kyle's systolic blood pressure is 1.75 above the average systolic blood pressure of men his age. Kyle's systolic blood pressure is 175. (d) Calculate Kyle's blood pressure. x =

a)

b)

c) Kyle's systolic blood pressure is 1.75 standard deviations above the average systolic blood pressure for men.

d)

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:

(a) 100 millimeters z-score =

(b) 150 millimeters z-score =

(c) Kyle's doctor told him that the z-score for his systolic blood pressure is 1.75. Which of the following is the best interpretation of his score?

1.75 standard deviations above the mean systolic blood pressure of males.

The problem does not talk about age.

So the answer is:

Kyle's systolic blood pressure is 1.75 standard deviations above the average systolic blood pressure for men.

d) Calculate Kyle's blood pressure

This is X when Z = 1.75. So

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
