Answer:
we have to compare the effects of method I and method II.
(a)
(i) The population of generalization if the method I is used will be all people who are willing to determine the effect of exercising with a training partner as compared to exercising alone.
(ii) The population of generalization, if method II is used, will be all people who exercise at a community fitness center.
(b)
If both the methods produce significant results then the difference between the conclusion of the method I and the conclusion of method II is that the result of the method I can be generalized to a broader population since it does not restrict people to participate in the study.
Answer:
let x = the number of nickels
the number of pennies can be represented by (56 - x)
.05x + .01(56 - x) = 1.52
5x + (56 - x) = 152 if in the above line we multiply both sides of the equation by 100
4x + 56 = 152
4x = 96
x = 24
There are 24 nickels and 56 - 24 = 32 pennies
24 nickels are worth 24 * 5 = $1.20 and 32 pennies are obviously worth 32 cents, so the total is 1.20 + 0.32 = $1.52
Step-by-step explanation:
The correct answer is A) 17
Why? Let's see ---
If an exponent means to multiply the base as many times as the exponent says, let's start with that.
3 x 3 x 3 x 3 = 81
4 x 4 x 4 = 64
Now we subtract each answer from each other -
81 - 64 = 17
