Answer:
The area of the bedroom actually is 453.75 sq ft.
Step-by-step explanation:
Given that,
A blueprint shows the master bedroom to be 5 inches long and 3 inches wide.
The scale on blueprint is 2 inches : 11 feet.
It means 2 inches = 11 feet.
Then,
1 inches feet = 5.5 feet.
So,
The length of the bedroom is 5 inches = (5×5.5) feet=27.5 feet
The wide of the bedroom is 3 inches = (3×5.5) feet= 16.5 feet
The area of the bedroom actually is = length × wide
=(27.5×16.5) square ft
=453.75 square ft
First problem:
Find the z score for raw score 6 minutes:
6 - 5
z = --------- = 1.429
0.7
Using a TI-83 calculator's distribution functions, I found that the area to the right of 6 minutes is
normalcdf(1.428,100) = 0.076
Regular price with tax:
329(1.085)
356.97
Marked down price:
329(.75)
246.75
add tax:
246.75(1.085)
267.72
356.97-267.72
he will save $89.25
