Answer:

A. A 180 degree rotation about the midpoints of AB.

Step-by-step explanation:

The rotation of a shape less than 360 degrees will carry the figure onto itself. A parallelogram is a rectangular shape which is slight diagonal shaped. The parallelogram will carry transformation when its rotation is about 180 degrees.

A deep sea diver is at 45 feet below sea level. A helicopter is at 100 feet above sea level. What is the distance between the he

Luden [163]

Answer:

D = 55 feet

Step-by-step explanation:

Let below sea level is negative direction and above sea level is positive direction.

A deep sea diver is at 45 feet below sea level = -45 feet

A helicopter is at 100 feet above sea level = +100 feet

We need to find the distance between the helicopter and deep sea diver. It can be calculated by simply adding the above data as follows:

D = -45 +100

= 55 feet

Hence, the distance between the helicopter and deep sea diver is 55 feet.

When Elena throws a shot put during track and field practice, it travels an average of 26 feet with a standard deviation of 3 fe

alexgriva [62]

Answer:

15.87%, that is, approxiately 16% of of her shots will travel less than 23 feet.

Step-by-step explanation:

Problems of normally distributed samples can be 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 question, we have that:

$\mu = 26, \sigma = 3$
