One month, 24 employees earned a bonus and 56 employees didn't earn one. Express the number of employees who received the bonus
anastassius [24]

Answer:

A. 24:56

Step-by-step explanation:

Let's find the answer by considering that 'X' represents the employees that earn the bonus and 'Y' the employees that didn't.

Where:

X=24

Y=56

Now, ''Express the number of employees who received the bonus as an unsimplified ratio to the number of employees who didn't receive the bonus'' means:

employees that earn the bonus : employees that didn't receive the bonus

which is:

X:Y = 24:56

In summary, the answer is A. 24:56.

Alan and his classmates performed a linear regression analysis on the data set shown below and found that the line of best fit t
stealth61 [152]

Answer:

C. y=\frac{4}{5}x+7

Step-by-step explanation:

Alan and his classmates found that the line of best fit through the data had the equation y=-\frac{5}{4}x+18

The slope of this line is m=-\frac{5}{4}

If a line would intersect this line of best fit at right angles, then the two lines are perpendicular to each other.

The slopes of perpendicular lines are negative reciprocals of each other,

Hence that line must have slope \frac{-1}{-\frac{5}{4}} =\frac{4}{5}

Therefore we look for a line whose slope is \frac{4}{5} from the given options.

That line is the third option y=\frac{4}{5}x+7

In the parallelogram shown, AE = p − 8, CE = 2p − 58, and DE = p + 15. What is the length of line segment EB?
Artist 52 [7]
<span>DE = EB

DE = p + 15

I would help you farther but I don't know what p equals. If you know then add that number with 15 and you have your answer.</span><span />
