We are given original selling price of book = $b.
Price is marked down by 46%.
46% can be written as 46/100 in decimals it would be 0.46.
Therefore, markdown as a decimal is 0.46
Now, markdown is 0.46 of original price = 0.46b
Therefore, new price after marked down can be written by expression =
b - 0.46b = 0.56b.
<h3>Therefore, the expression for the sale price of the hardcover book is 0.56b.</h3>
If original retail price was = $29.00.
The sale price would be 0.56b = 29*0.56 = $15.66.
Total saving = 29-15.66 = $13.34.
Therefore, you save $13.34 by paying the sale price $15.66.
Please check this out I think it’s correct !!!
Answer:
262.25 inches
Step-by-step explanation:
65% of 165 is 107.25
107.25+165=272.25
so the truck is 262.25 inches long
Answer:
The limit that 97.5% of the data points will be above is $912.
Step-by-step explanation:
Problems of normally distributed samples can be solved using 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 problem, we have that:

Find the limit that 97.5% of the data points will be above.
This is the value of X when Z has a pvalue of 1-0.975 = 0.025. So it is X when Z = -1.96.
So




The limit that 97.5% of the data points will be above is $912.
