Answer:
You have a 25%, or 1/4 chance that you will choose a yellow paper clip.
Step-by-step explanation:
1) First, you want to find the total number of paper clips.
6 + 3 + 4 + 2 + 5 = 20 total paper clips
<u>This is your denominator.</u>
2) From the problem, we can understand that there are 5 yellow paper clips.
<u>This is your numerator.</u>
3) From the numerator and denominator we have from above, your fraction is 5/20.
4) This can be simplified into 1/4, which is 25%.
If you randomly purchase one item, the probability it will last longer than 9 years is; 11.12%
<h3>How to find the probability from z-score?</h3>
The formula for Z-score is;
z = (x' - µ)/σ
where;
x' = sample mean
µ = population mean
σ = standard deviation
Thus;
z = (9 - 7.9)/0.9
z = 1.22
From online p-value from z-score calculator, we have;
probability = 0.1112 = 11.12%

Answer:
Seth watched TV for 6 3/4 hours last week.
Step-by-step explanation:
Let x be the number of hours he watched TV last week.
(2/3)x = 4 1/2 hrs. Solve for x by mult. both sides by (3/2):
(3/2)(2/3)x = (3/2)(9/2)
Then: x = 27/4 hours, or 6 3/4 hours.
Seth watched TV for 6 3/4 hours last week.
