What is the y-coordinate of the midpoint of WU? A 2.5 B. -1.5 C. -0.5 D. 1.5

lilavasa [31]

Option C: -0.5 is the right answer

Step-by-step explanation:

Given is the graph on which different points are indicated.

We have to find the y-coordinae of the mid-point of WU.

The formula for mid-point is:

$(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})$

So we only have to know the y-coordinates of both points to find the mid-points y coordinate

So by observing the graph we get

y_1 =0

y_2 = -1

So,

$\frac{0-1}{2}\\= \frac{-1}{2}\\= -0.5$

Hence,

Option C: -0.5 is the right answer

Systolic Blood Pressure Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury and the stan

liq [111]

Answer:

0.1425 = 14.25% probability that the individual's pressure will be between 119.4 and 121.4mmHg.

Step-by-step explanation:

When the distribution is normal, we use 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 question, we have that:

$\mu = 120, \sigma = 5.6$
