Answer:
15.6
Step-by-step explanation:
First, multiply the midpoint of each class by its frequency, as follows:
Class midpoint frequency midpoint*frequency
0-9 4.5 24 4.5*24 = 108
10-19 14.5 20 14.5*20 = 290
20-29 24.5 32 24.5*32 = 784
Total 76 1182
The mean is computed as the division between the addition of the "midpoint*frequency" column by the addition of "frequency" column.
mean = 1182/76 ≈ 15.6

4 because 40 divid 2= 20 ,40 divid 4=10 ,40 divid 8=5, 40 divid 12=36 remainder 4 remainder =what is left
-1-7x-6(-7-x)=36
-1-7x+42+6x=36
41-7x+6x=36
41-x=36
-x=36-41
-x=-5
Answer: x=5
I think it’s just asking you to add the two functions (f + g)(x)
If f(x) = sqrt x + 3
And g(x) = x + 2
Then (f + g)(x) = (sqrt x + 3) + (x +2)
And I’m pretty sure that’s all you can simplify
