Solve (x-8)(4x+2)= 0 using the Zero Property

x = 8 or x = -1/2

Step-by-step explanation:

given:

(x-8)(4x+2)= 0

by zero property:

(x - 8) = 0

x = 8

or

(4x+2) = 0

4x = -2

x = -2/4

x = -1/2

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.
