She needs a 95 because the average without 95 is 88.75 then 85 + 80 + 92 + 98 + 95 = 450 then 450÷5=90 so 95 is the answer

In this example, the word "GEOMETRICAL" has 11 letters and 5 of them are vowels. They are: E, O, E, I, A. The probability of picking a vowel is 5/11. We could say that there are 5 out of 11 chances of a vowel to occur whenever a piece of paper is taken out of the bag.

How do I round 4.75 up to the nearest whole number
Ksenya-84 [330]
4.75.
the whole number is 4
circle 4 and see whether the number beside it
in this case its 7
(Any number that is 5 - 9 causes the number that you are rounding off to to increase)
( any number that is 4-1 causes the number that you are rounding off too to remain)
in this case since its 7 which more that 5 and the whole number increases therefore the final answer is 5.

Hope this helps! xD
