Jack's last six scores are 75,78,83,80,79,84. If he scores a 90 on the next test, by how much will his mean test score increase?

kondaur [170]

Answer:

1.46

Step-by-step explanation:

First find the the mean score before he made a 90.

$\frac{75+78+83+80+79+84}{6} = 79.83$

Now add the score of 90 and calculate.

$\frac{75+78+83+80+79+84+ 90}{7} = 81.29$

Subtract the two scores.

$81.29-79.83 = 1.46$

His mean test score increased by 1.46.
