Answer:

The answer is B

Step-by-step explanation:

You order them from least to greatest- 16, 17, 19, 24, 28, 30, 31, 32, 36, 37, 40, 43, 45.

Then you find the middle number or the median- 31

Then you go to the left of the medain and get the first quartile- 19, 24 (You have to find the mean of these two numbers- 21.5)

Then you go to the right of the medain and get the third quartile- 37, 40 (Again you must find the mean of these two numbers- 38.5)

Last you would put them in the order needed.

Hope this helps! :)

Please help with number 3!! I can’t figure it out.
FrozenT [24]

Answer:

Gabe worked 65, Abe worked 62 and Babe worked 69.

Step-by-step explanation:

Let Gabe = x

Therefore, Abe worked: x-3 and Babe worked x+4

So,

x+(x-3)+(x+4)=196

3*x+1=196

3*x=195

x=65

Then,

x-3= 62

x+4=69

What is the slope of a line perpendicular to the line of y=-1/4x-1
harina [27]

Answer: 4

The given line has a slope of -1/4 as this is the number in front of the x. The general equation y = mx+b has m as the slope. So m = -1/4 is given

Flip the sign to get -1/4 turn into +1/4 or just 1/4

Then flip the fraction (aka reciprocal) to go from 1/4 to 4/1 and that simplifies to 4.

Multiplying the original slope (-1/4) and the perpendicular slope (4) will result in -1.
