The list below shows the prices of T-shirts at a clothing store. {8, 10, 10, 12, 15, 15, 18} Which statement best describes the mean of this set? the difference between the least and greatest prices the sum of the prices the quotient of the difference between the least and greatest prices divided by 7 the sum of the prices divided by 7

sum of the prices divided by 7

Step-by-step explanation:

Formula for mean:

Given: The prices of T-shirts at a clothing store:  {8, 10, 10, 12, 15, 15, 18}

Here number of observations = 7

According to the formula of mean,

The statement that describes the mean of this set = sum of the prices divided by 7

Hence, the correct statement : sum of the prices divided by 7

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
