Complete Question

​The mean quiz score for 8 students is 50. The scores for 7 of the 8 students ​are shown below:

20, 20, 20, 30, 80, 80, 80

What is the score for the remaining student? ​​

Answer:

70

Step-by-step explanation:

​The mean quiz score for 8 students is 50.

The total score of the students is

Mean × Number of students

Total score of the students = 50 × 8

= 400

From the attached image, and the question above, the scores of the students were given in a dot plot

and interpreted as:

20, 20, 20, 30, 80, 80, 80

Hence, the total scores of the 7 students is

20 + 20 + 20 + 30 + 80 + 80 + 80

= 330

The score of the 8th and remaining student is calculated as:

400 - 330 = 70

scoray [572]
(67 + 68 + 78 + x) / 4 = 70
(213 + x) / 4 = 70
213 + x = 70 * 4
213 + x = 280
x = 280 - 213
x = 67

(213 + x) / 4 = 79
213 + x = 79 * 4
213 + x = 316
x = 316 - 213
x = 103

lowest u can make is 67, highest u can make is 100
