Len wants to paint a wall in his house. he knows that 1 can of paint covers an area of 32 feet. the dimensions of the wall are shown. shade in the correct number of paint cans he will need to buy.

Len needs to buy 3.75  paint cans

Step-by-step explanation:

Given:

Length of the wall = 12 feet

Width  of the wall = 10 feet

1 can of paint covers an area of 32 feet.

To Find:

Number of cans needed to paint the wall = ?

Solution:

Thea area of the wall is length x breadth

Area = 12 x 10 = 120 square feet

One can cover can cover 32 feet

Then to cover 120 square feet

The number of cans needed will be  =

The number of cans needed will be = 3.75

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
