❖ To find the mean, add up all the numbers and divide by the amount of numbers there are. To find the range, subtract the highest number by the lowest number in the data set.
2. Mean = 35 Range = 78
3. Mean = 43 Range = 58
4. Mean = 63 Range = 73
5. Mean = 61 Range = 56
6. Mean = 55 Range = 83
7. Mean = 61 Range = 53
8. Mean = 60 Range = 75
9. Mean = 50 Range = 76
10. Mean = 50 Range = 81

To solve, simply simplify each fraction
(16/32)/(16/16) = 1/2
(12/24)/(12/12) = 1/2
True, the equation given to us is true.
hope this helps
13 divided by 11.3 is 1.150442477876106. So 15 by 1.150442477876106 and you get 13.03846162772485. Just round it to the nearest tenth and you get 13.0.
So all you have to do to solve these problems is substitute the y coordinate and the x coordinate into the equation.
So question 1 would be true because when you substitute the numbers in it equals the y value.
Question 2 is (4, -7)
Question 3 is False
Question 4 is true
Question 5 is true
See if you can do the rest!
