Which are possible prices for the camera?
a. $110, $135, $115, $120
b. $120, $145, $130, $130
c. $140, $135, $160, $150
d. $125, $135, $150, $130

d. $125, $135, $150, $130

Step-by-step explanation:

$125, $135, $150, $130

Range of the above set of numbers:

$150 - $125 = $25

Mean of numbers:

$125 + $135 + $150 + $130 = $540

540 ÷ 4 = $135

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
