Tasha's scores on her first five tests were as follows. 74, 90, 92, 83, 81 what would tasha have to score on the sixth test to have a mean of 85?

For this case, what we must do is calculate the mean of the given data.
 For this, we must do the following:
 Add the given numbers and divide by the number of numbers.
 We have then:
 
 From here, we clear the value of x.
 We have then:
 
 
 Tasha would have to score 90 on the sixth test to have a mean of 85

The correct answer would be the function g(x) increased at a faster rate

Dis the correct  answer
