The area of a rhombus is given by the formula a=1/2xy,where x and y are the lengths of the diagonals. if the diagonals of a rhombus have lengths 10cm and 20cm, find the area of the rhombus.

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
