Answer:
C. $5.55
Step-by-step explanation:
Total cost of installing 60 square feet of flooring
= $253.00 + $80
= $333
Total number of square feet for flooring = 60
Now cost per square foot of the flooring
= total cost/total number of square feet
That’s
$333/60 = $5.55
Each square foot cost $5.55
Answer:
74.5%
Step-by-step explanation:
The total number of people sampled is 1000 people.
There are 745 people who where corrective lenses.
Percent is (part)/(whole); in this case, the part is 745 and the whole is 1000, so:
745/1000 = 74.5%
Thus, the answer is 74.5%.
Hope this helps!

Answer:
The score that cuts off the bottom 2.5% is 48.93.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
What is the score that cuts off the bottom 2.5%
This is X when Z has a pvalue of 0.025, so X when Z = -1.96.
The score that cuts off the bottom 2.5% is 48.93.
