Answer:
There wasn't really a question here but for both the answers is
for year 2 we got 12 sales
for year 3 we got 18 sales
Step-by-step explanation:
since the first year Mr.Jackson sold 3 computer monitors then in the second year he must've multiplied the times he had sold it which means 4 x 3 which equals 12
as well as the third year, on the third year he sold 6 times the first year so it means 6 x 3 which equals 18
When finding the mean you add up the numbers that are needed to find the mean and divide them by the amount of numbers you added. For example question 5 you will add 58+58+62+55+49+48 which will equal 330 and then divide it by 6 because there are 6 numbers which is 55.

Step-by-step explanation:
Answer: Pyramid A: Base is rectangle with length of 10 meters and width of 20 meters.
Pyramid B: Base is square with 10 meter sides.
Heights are the same.
Step-by-step explanation: The volume of pyramid A is TWICE the volume of pyramid B.
If the height of pyramid B increases to twice the of pyramid A, (from 10m to 20m),
V of square pyramid = (10m)² * (10*2)/3 = 100m² * 20m/3 = 100m² * 6.67m = 666.67 m³
The new volume of pyramid B is EQUAL to the volume of pyramid A.
