Which of the following is a solution of the equation n/4-8=-6? A. n = 8
B. n = 1/2
C. n = -56
D. n = -8

PLZ HELP ASAP

a. n=8

Step-by-step explanation:

to solve an equation, we must do the same operations to both sides.

step 1- add 8 to both sides. now n/4-8=-6 becomes n/4=2

step 2- multiply both sides by 4. so n/4=2 becomes n=8, which gives us our answer.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
