While deciding whether to get a job or to continue your education, you consider two small, local companies that are hiring: KwikFix and MongoRama. You learn that both employers consider you to be on par with their average worker. You do some research on the hourly wage each company pays. You find that MongoRama pays nine employees $9.00 per hour each, while one employee makes $30.00 per hour. KwikFix pays two employees $9.00 per hour, five employees $10.50 per hour, two employees $12.00 per hour, and one employee $16.50 per hour.

1) Calculate the mean and the median for the salaries of the two companies, each of which has 10

Answers

Answer:

KwikFix

median: 9.00 mean: 11.1

MongoRama

median: 10.50 mean: 11.1

Step-by-step explanation:

The median is found by ordering the numbers least to greatest and the number in the middle is the median, which is how you find the median for the each company. For the mean you add up all of the workers wages and then divide it by the number of workers.

The first company, Kwikfix, the mean is 9 and the median is 11.1. The second company, MongoRama, the mean is 10.5 and the median is 11.1.

A line has a slope of negative 3 and a y-intercept of 3 what is the x intercept of the line

Answers

Answer:

Step-by-step explanation:

y = mx+b where m is the slope and b is the y intercept

y = -3x +3

We want to find the x intercept

Set y = 0 and solve for x

0 = -3x+3

Subtract 3 from each side

-3 = -3x

Divide each side by -3

-3/-3 = -3x/-3

The mayor of a town proposes to fence off a triangular area of a building that includes two sides of the building as shown below.
Which distance, in feet could be the length of the proposed fence line?

Answers

Answer:

i would say C

Step-by-step explanation:

the image shown in the attachment is what i assume is the question and answers you need.

I say C as with my experience of hypotenuses is that it is a + b = c and we can probably say that the fence line is the hypotenuse as it looks to be longer than the other two. And since we have 200 feet and 70 feet 200+70 = 270 which is not enough to be 280 so it would have to be C.

Also it would NOT be B or A as the hypotenuse has to be longer and the other two choices are shorter than the combined.

C would be the closest to a realistic answer without going over 270. This is just a really bad question to have to answer especially since it is angled so weird. But i am fairly certain it is C

The only possible answer is D. Two shorter sides of a triangle must add up to more than the longest side of any triangle.
