Answer:
D. 8
Step-by-step explanation:
We have been given that the number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Further, 95 percent of all homes are on the market between 40 and 72 days.
As per empirical rule 95% of the data on bell curve lies between 2 standard deviations of mean.
So we can set an equation as:
or
Therefore, the standard deviation for our given data is 8 and option D is the correct choice.
E+14 is 100000000000000, so 1.783864 times that is 178386400000000
B this is the correct answer because it is
3/3 because you have Two numbers that are greater than three out of three numbers which will give you 2/3 and then you have four which is an even number out of three numbers which will give you 1/3 you add them together which will give you 3/3 and which will equal one whole
Answer:
Both sides are 44
Step-by-step explanation:
5n - 11 = 2n + 22
5n - 2n = 22 + 11
3n = 33
n = 11
First Side
5n - 11 = 5 (11) - 11 = 55-11 = 44
Second Side
2n + 22 = 2 (11) + 22 = 44
