True. College graduates often spend more money on lottery tickets than those with only a high school education, hoping to win big to pay off student loans. Hope this helps!
Using the normal distribution, it is found that there is a 0.877 = 87.7% probability of a bulb lasting for at most 569 hours.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:

The probability of a bulb lasting for at most 569 hours is the <u>p-value of Z when X = 569</u>, hence:


Z = 1.16
Z = 1.16 has a p-value of 0.877.
0.877 = 87.7% probability of a bulb lasting for at most 569 hours.

Answer:
D. 6 1/12
Step-by-step explanation:
3 2/3= 3 8/12, 1 3/4= 1 9/12, 2/3= 8/12 || add (3 8/12+ 1 9/12+ 8/12= 4 25/12= 6 1/12)
