First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.
Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.

The updated IQR is 14.54.
Step-by-step explanation:
The interquartile range is given by the difference between the 75th percentile(value that is greater than 75% of the measures) and the 25th percentile.
This means that each piece of wood is actually 5 inches shorter than the value recorded by the employee.
This means that the length of each wood is less than 5. However, the difference between the 75th percentile and the 25th percentile will stay the same, since both were subtracted by 5.
The updated IQR is 14.54.
The probability that none of the shoes are black is 51.2%.
If 20% of the shoes are black, then 80% of the shoes are not black. To find the probability that three shoes are not black, we have to multiply 80% by itself 3 times.
0.8 x 0.8 x 0.8 = 0.512 = 51.2%
