The area of a triangle A is 8 square units. The area of triangle B is 72 square units.

a) What scale factor was used to get from triangle A to triangle B?

Scale Factor =

b) Using the same triangle A that has an area of 8 square units as the original, what would be the area be of a scaled copy that was drawn using a scale factor of 5?

Area =
square units

A) 9 B) 40 sq units.

Step-by-step explanation:

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.

c is the correct answer
