Josh has scores of 16,19 and 23 on three quizzes what score must he get on the next quiz to have an average of at least 20?

Hi,
Let the score be x
average=sum of observations/no. of observations
20=16+19+23+x/4
20=58+x/4
20*4=58+x
80=58+x
80-58=x
x=80-58
x=22
To get at least 20, he should at least score 22 in his next quiz.
Hope this helps you.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
