John scored a mean of 19 points in his first.3 basketball games. In his fourth game, he scores 23 points. What is his average score for all four basketball games?

20

Step-by-step explanation:

We are told in the question that

John scored a mean of 19 points in his first 3 basketball games

His total points for his first 3 games = Number of games × Mean of those games

= 3 × 19

His total points for his first 3 games = 57 points

We aslo told that in his fourth game, he scores 23 points.

His average score for all four basketball games is calculated as:

(57 points + 23 points) ÷ 4 games

= 80 points ÷ 4 games

= 20

His Average for the four games = 20

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
