Triangle abc is dilated to create triangle def on a coordinate grid. you are given that angle a is congruent to angle d. what other information is required to prove that the two triangles are similar? angle b is congruent to angle d. segments ab and de are congruent. angle b is congruent to angle e. segment ac is congruent to segment df, and segment bc is congruent to segment ef.

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.

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
