Step-by-step explanation:

So the way you do this is if it says 'Find AC' and on the angle you see different letters connect then on the lines and name the angle

More that 90°= Obtuse

90° angle= 90° angle

Less than a 90° angle= isosolines angle

(1 point) The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with a mean of 12

garik1379 [7]

Answer:

a) $Z = -2.7$

b) $Z = 2.3$

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

d) $X = 144.5$

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

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:

$\mu = 127, \sigma = 10$

(a) 100 millimeters z-score =

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{100 - 127}{10}$

$Z = -2.7$

(b) 150 millimeters z-score =

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{150 - 127}{10}$

$Z = 2.3$

(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

$Z = \frac{X - \mu}{\sigma}$

$1.75 = \frac{X - 127}{10}$

$X - 127 = 1.75*10$

$X = 144.5$

A grocery store usually orders 1500

Annette [7]

Answer:

40%

Step-by-step explanation:

The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original. An increase of 5 percent would indicate that, if you split the original value into 100 parts, that value has increased by an additional 5 parts. So if the original value increased by 14 percent, the value would increase by 14 for every 100 units, 28 by every 200 units and so on. To make this even more clear, we will get into an example using the percent increase formula in the next section.
