Answer the questions below

mean= 50

median = 40

mode 95

Step-by-step explanation:

Put the numbers in order from smallest to largest

7,12,13,40,88,95,95

The mean is adding up all the numbers and dividing by the number of numbers

(7+12+13+40+88+95+95)/7

350/7 = 50

The median is the middle number

7/2 = 3.5

Round up so the 4th number is the median

40 is the median

The mode is the most often which is 95 since is appears twice

Let's put them from least to greatest:

7, 12, 13, (40), 88, 95, 95

The median would be the number in the middle, therefore it's 40.

To get the mean, add them all together and you'll get 350. There are 7 numbers, do 350 divided by 7 and you'll get 50.

The mode mode would be 95. The mode is 95 because there's more than one of the same number.

Hope this helps!

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
