Lucy knows about 6 Web sites that sell a designer T-shirt she loves. The mean price of the T-shirt is $14 and the range of price is $7. What are possible prices for the T-shirt?

D

Step-by-step explanation:

Given that :

Mean = 14

Range = 7

Evaluating the options given :

A. $14, $14, $14, $14, $7, $7

For option A :

Mean = (14 + 14 + 14 + 14 + 7 + 7) = 70 / 6 = 11.66 (incorrect)

B. $14, $14, $14, $14, $14, $21

Mean = (14 + 14 + 14 + 14 + 14 + 21) = 91 / 6 = 15.17 (Incorrect)

C. $13, $13, $13, $15, $15, $15

Range = 15 - 13 = 2 ( Incorrect)

D. $13, $12, $15, $15, $11, $18

Range = (18 - 11) = 7

Mean = (13+12+(15*2)+11+18) / 6 = 84/6 = 14

Option D is Correct

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
