What is the solution to this inequality x- 6 < -4

A- x > -10
B- x > 2
C- x < -10
D- x < 2

(B) x < 2

Step-by-step explanation:

x - 6 < - 4

x < - 4 + 6

x < 2

x ∈ ( - ∞ , 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.

b.an increase in a causes b to decrease
