Answer:
Mean = 12
Step-by-step explanation:
The arithmetic mean of a distribution is the sum of the number of samples in the distribution divided by the number of samples in the dataset. It is a measure of central tendency. The mean is represented as follows:
Mean = 12
Answer:
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.
Step-by-step explanation:
or just 990
3/5(15d+20)−1/6(18d−12)=38
Simplify
3/5(15d+20)−1/6(18d−12)=38
(3/5)(15d)+(3/5)(20)+−3d+2=38(Distribute)
9d+12+−3d+2=38
(9d+−3d)+(12+2)=38(Combine Like Terms)
6d+14=38
Subtract 14 from both sides.
6d+14−14=38−14
6d=24
Divide both sides by 6.
6d/6 = 24/6
d=4
