Find the mean of this set of numbers.

7, –9, 6, –10, –13, –5

7+(-9)+6+(-10)+(-13)+(-5)=
7-9+6-10-13-5=
-24

mean is the sum of all the numbers divided by the total number of numbers within the data.

-24÷6=-4

The mean is -4.

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
