Find the mean of the scores to the nearest tenth

3.6

Step-by-step explanation:

First you would add up all the numbers, 4+3+9+2+3+4= 25

Then divide 25 by 7, because thats how many digits we have, so 25 divided by 7 would be 3.57142857143

To round to the nearest tenth (first place behind the decimal) We would round 5 up to 6. So the mean would be 3.6

If you need me to explain better or you need me to explain the formula, just ask  

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
