Answer: 0.1788
Step-by-step explanation:
We assume that the monthly rent for a one-bedroom apartment without a doorman in Manhattan is normally distribution.
Given : Mean monthly rent :
Standard deviation :
Sample size :
Let x be the monthly rent of randomly selected apartment.
Now. we calculate the value of z-score by the formula :
For x = $2,700
The p-value =
Hence, the probability that the average rent of the sample is more than $ 2,700 = 0.1788
Answer:
4. 30 inches
5. 76.2 cm
6. 1024 sqaure inches
Step-by-step explanation:
4. √900 = 30 (area of a square = s²)
5. 30*2.54 = 76.2 cm
6. Each side is 2 inches longer ⇒ 30+2 = 32 inches (each side length)
area of a square = s²
32² = 1024 square inches
5x+13=4x+2+2x-9
6x-7=5x+13
x=20
80+2
4x+2=82
5x+13=113
Answer: 52
Step-by-step explanation:
We know that 25 percent is one-fourth, so whatever number divided by 4 equals 13. To do this, we can just multiply 13 by 4 to get our answer, 52.
