okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)

89%

Step-by-step explanation:

if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%

more plz help i kinda suck at dependent and independent

Answers

Answer:

I think T is the independant and B is the dependant

Step-by-step explanation:

the amount of time they have is not changed, however the amount of bands they can fit into that time slot is undetermined and relies on the time they have

Answer:

the first option

Step-by-step explanation:

independent is something you can change OR determine

dependent is something that will happen BECAUSE of the independent and you can not change it

in this case- the sentence states that " the amount of time that the venue has been reserved for DETERMINES how many bands will play"

You can change or schedule how long you want to reserve the venue but how many bands that will play depends on the independent variable (t)

Thats why it say determines, because (t) determines or changes (b)

Your answer is 2 pi/π r.

The formula of a circumference is always 2 pi r.

18 x 3.14 x 2 = 113.04

in this case radius is 18

pi is 3.14

2 is just always there when finding out circumference.

Answer:

113.04 (estimated)

Step-by-step explanation:

I used the formula that includes pi.

basically multiply the radius by 2 and multiply the answer with π or 3.14 for the estimation.
