Andre is in the band and he is conducting an experiment to determine if high school students find listening to classical music or listening to the sounds of the ocean more calming. He selects five students at random from the band to listen to classical
music. He then selects five people at random from the swim team to listen to the sounds of the ocean. What is problematic
about the way that Andre selected his groups?

I would say because he choose 5 for each in stead of just choosing 5 period for both of them  so they can listen to both instead of just having 5 listening to CLASSIC and a different 5 listening to OCEAN music, another problem is the amount of people he choose is uneven it should be even so  that  if it is 5 well there wasnt another student to change it if it is even then there could be like 3 for OCEAN music and maybe 2 for CLASSIC music if it ends out 3 for both just add 2 more kids.

I Hope this helped. :)

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
