Answer: The above described question is an EXPERIMENT.
Step-by-step explanation:
- The subjects studied were ==> 40
- The factors studied, and the number of levels for each==> 2factors were studied, each having 2 levels(desserts /no desserts and exercise/no exercise).
-The number of treatment ==> 4
-The response variable ==> Improvement in sleep ability.
$7.64 because 0.68 times 48 is $32.64 and 32.64 - 25.00 is 7.64
The answer is A) x = 9
We know this because every four sided figure has angles that measure up to 360. So we can subtract all of the angles and then use the remaining angle to solve the problem.
360 - 90 - 90 - 99 = 81.
So with the remaining angle being 81, we can solve for x.
x^2 = 81
x = +/-9
Since +9 is the only answer that makes sense in this case, x = 9.
