Answer:
8
Step-by-step explanation:
3(8-m)=5m-40
you first distribute 3 through the parenthesis
24-3m=5m-40
Move the variable to the left and change sign
24-3m-5m=-40
now move the constant to the right
-3m-5m=-40-24
collect like terms
-8m=-40-24
-8m=-64
Divide both sides by -8 and negative divide negative number becomes positive
so m = 8

Step-by-step explanation: but I think that 2+2=4 I think that’s correct and thanks for the points.
I’m sorry but I actually don’t know
Mean = 450 sec
standard deviation = 50 sec
450-50 =400
450+50=500
Between 400 sec and 500 sec means one deviation above and one deviation below the mean, and it is 68%.
68%=0.68
0.68*288= 195.84≈196
Answer is d) 196
