Answer:  5.8 (choice B)

=================================================

Explanation:

To find the length of the median, we add up the parallel sides and divide by 2. In other words, we're averaging the parallel sides to get the length of the midsegment shown.

FE = (WX + VY)/2

FE = (4.5 + 7.1)/2

FE = 11.6/2

FE = 5.8

a data set has a mean of 68 and standard deviation of 6. An element in this set is 51. What is z-score for 51? Round your answer
gogolik [260]

z = -2.83

<u>Explanation:</u>

Given:

Mean, μ = 68

Standard deviation, σ = 6

Data point, x = 51

Z score, z = ?

We know:

z = \frac{data point - mean}{standard deviation} \\\\z = \frac{x - u}{p}

Substituting the value we get:

z = \frac{51-68}{6} \\\\z = -2.83

A negative z score says that the data point is below average.

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2,4)?
pav-90 [236]

Answer:

y=-5/2x-1

Step-by-step explanation:

change the equation to slope intercept form

y=-5/2x+6

graph the point (-2, 4)

use the slope of the equation to find the y intercept

y intercept = -1

write equation of the parallel line using the same slope of the first line

-5/2x

and the y intercept of the new parallel line -1

y=-5/2x-1
