Answer:

X-Axis

When a figure flips over the X-axis, the X coordinate stays the same while the Y-coordinate’s sign is flipped.

Y- axis

When a figure is flipped over the Y- axis the Y coordinate stays the same while the X axis coordinate’s sign is flipped

Example- (x,y)

X axis flipped

(2,5) —> (2,-5)

Y axis flipped

(3,5) —-> (-3,5)

In 2014, the CDC estimated that the mean height for adult women in the U.S. was 64 inches with a standard deviation of 4 inches.

Vladimir79 [104]

Answer:

A. 16%

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 problem, we have that:

$\mu = 64, \sigma = 4$

Which of the following gives the probability that a randomly selected woman has a height of greater than 68 inches?

This is 1 subtracted by the pvalue of Z when X = 68. So

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

$Z = \frac{68 - 64}{4}$

$Z = 1$

$Z = 1$ has a pvalue of 0.84.

1 - 0.84 = 0.16

So the correct answer is:

A. 16%

What are perfect numbers? Find the only 3examples below 500

liubo4ka [24]

The first two are 6 and 28. The factors of 6 add up to the same thing as 6.

Six

1 * 2 * 3 = 6

1 + 2 + 3 = 6

Twenty eight

1 + 2 + 4 + 7 + 14 = 28 (the multiplication is not the same as for 6).

Four hundred ninety Six

This one is kind of hard to believe

It is 16 * 31

1 + 2 + 4 + 8 + 16 + 248 + 124 + 62 + 31 = 496
