explanation:
In an observational study, we measure or survey members of a sample without trying to affect them. In a controlled experiment, we assign people or things to groups and apply some treatment to one of the groups, while the other group does not receive the treatment
Hey there!
First, let's list the factors of 40:
1 x 40, 2 x 20, 4 x 10, 5 x 8,
We need to figure out which pair of factors has a sum of 13.
1 + 40 = 41 --> Nope
2 + 20 = 22 --> Nope
4 + 10 = 14 --> Nope
5 + 8 = 13 --> Yes!
The two numbers that have a product of 40 and a sum of 13 are 5 and 8.
Hope this helps!
