Answer:
Step-by-step explanation:
Ok, so we start by setting the integral up. The integral we need to solve is:
so according to the instructions of the problem, we need to start by using some substitution. The substitution will be done as follows:
U=5+x
du=dx
x=U-5
so when substituting the integral will look like this:
now we can go ahead and integrate by parts, remember the integration by parts formula looks like this:
so we must define p, q, p' and q':
p=ln U
q'=U-5
and now we plug these into the formula:
Which simplifies to:
Which solves to:
so we can substitute U back, so we get:
and now we can simplify:
notice how all the constants were combined into one big constant C.
It would be 20
To get this answer you would add up all the answer then divide it by how many numbers there are
18+23+10+39+22+17+16+15= 160
160/8 = 20

Class Boundaries Frequency
5-10 8
10-15 9
15-20 15
20-25 10
25-30 8
30-35 6
----------
total 56
Average =
[5+10]/2*8+[10+15]/2*9+[15+20]/2*15+[20+25]/2*10+[25+30]/2*8+[30+35]/2*6

That is 1075 / 56 = 19.2
Answer: 19
Answer:
Multiplacation
Step-by-step explanation:
It is the multiplacation roperty pbecauseyou are multipyling 10 times x and 3.
Answer:
x needs to be smaller or equal to -3
Step-by-step explanation:
-3x7 = -21
you get there by dividing -21 by 7
example smaller number: -4x7 = -28
