1 answer:
Answer:
Equation :
She can make 20 bows with 8 yards of ribbon
Step-by-step explanation:
Gloria needs 2/5 yard of ribbons to make each bow.
Length of 1 bow =
Let r be the no. of bows made
So, Length of r bows =
We are given that she can make r bows with 8 yards of ribbon
So, Equation :
r=20
Hence She can make 20 bows with 8 yards of ribbon

Answer:
The minimum value of the bill that is greater than 95% of the bills is $37.87.
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 are the minimum value of the bill that is greater than 95% of the bills?
This is the 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.
The minimum value of the bill that is greater than 95% of the bills is $37.87.
