I think A, C, D are right because of the 12 pairs of heels, 6 are black (6/12) That means half of them could be chosen and be black (0.5). Another way to write 0.5 is as a percentage, 50%.

Find the mean, median, and mode 77, 92, 80, 92. Please explain how you got your answer.

vaieri [72.5K]

Answer:

The mean is 85.25

The medium is 86

The mode is 92

Step-by-step explanation:

The mean is all the numbers added divided by the number of values.

77 + 92 + 80 + 92 divided by 4

341 divided by 4 = 85.25

The median is the middle number

92 + 80 divided by 2

172 divided by 2 = 86

The mode is the number that occurs the most which is 92.

It takes a printer 2 1/2 min to print 24 black-and-white pages and 4 color pages. It takes the same printer 3 1/4 min to print 3

Multiply the first equation by 1.5, to get:
$(1.5)(24b + 4c) = 1.5(2.5)$
$36b + 6c = 3.75$
Subtract the second equation from this:
$6b = 1/2$
$b = 1/12$
Substituting into the first equation:
$24b + 4c = 2.5$
$24*(1/12) + 4c = 2.5$
$2 + 4c = 2.5$
$4c = 0.5$
$c = 1/8$
Therefore, it takes 1/12 minute to print a black-and-white page, and 1/8 minute to print a colored page.
