Answer:

Option C .a perpendicular bisector

Step-by-step explanation:

We are given a figure that represent a step in a compass and -straightedge construction.

We have to identify which type of construction

When we draw a perpendicular bisector

Then we put the compass on point A' take distance greater than half of A'B' and draw an arc C' and then put the compass on point B' and do not change compass as like in previous step and draw an arc and intersect the arc C'

Then , draw a line passing through of intersection of two arc which is perpendicular and bisect the A'B'.

Hence, given figure represent a perpendicular bisector.

Therefore, option C is true.

Can anybody teach me how to solve this pls

wel

Answer is 10 and 170, complementary angles are 90°, while supplementary angles are 180 in total, if angle A is 80 then you subtract 90 by 80 and you get 10, so that is angle B, So then you are asked what is angle C. Which is part of the supplementary angle so you take the 10° that you got from B and then you subtract 180 by the 10, And thats how you get 170 and that's how you know that C is 170 (hope this explanation helps)

For a data set of the pulse rates for a sample of adult? females, the lowest pulse rate is 39 beats per? minute, the mean of the

Zarrin [17]

Answer:

a) The difference is of 35 beats per minute.

b) So 3.07 standard deviations below the mean.

c) Z = -3.07.

Step-by-step explanation:

Z-score:

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

In this question:

Mean $\mu = 74$ , standard deviation $\sigma = 11.4$
