answer. (d. band is the most popular elective among juniors. “am sure of it”

The correct option is D.

Step-by-step explanation:

From the given two way relative frequency table it is clear that the probability of

Junior - Art = 0.02

Junior - band= 0.27

Junior - choir= 0.24

Junior - Drama= 0.05

Since the probability of Junior - band is highest amount the courses for juniors, therefore band is the most popular elective among juniors.

Senior - Art = 0.12

Senior - band= 0.04

Senior - choir= 0.05

Senior - Drama= 0.21

Since the probability of Senior - Drama is highest amount the courses for seniors, therefore drama is the most popular elective among seniors.

Therefore the correct option is D.

the answers are in the images, i received 100% on this assignment. hope this !

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
