Javon's first 3 quizzes had a mean score of 90%. If he scores 46% on his next quiz, what will be his mean quiz score for these 4 quizzes?

79%

Step-by-step explanation:

Javon's first 3 quizzes had a mean score of 90%. This means that his total score will be:

= 90% × 3

= 270%

Since he scores 46% on his next quiz, we add it to the previous score and this will be:

= 270 + 46

= 316

Then, his mean quiz score for these 4 quizzes will be:

= Total score / Number of quizzes

= 316 / 4

= 79%

79%

Step-by-step explanation:

316 / 4 = 79%

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
