Step-by-step explanation:

You didn't give the box plot, but to obtain the percentage of people between 20 and 37 years old, first of all, find the total number of people, T. Next, find the total number of people between 20 and 37 years old, t.

Then the percentage we want to find is:

P = T/t × 100

Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his. Let r equal the number of stamps Ch
S_A_V [24]

Answer:

Option C is correct.

The expression represents the number of stamps Erykah has : 3r -6

Step-by-step explanation:

Let r be the number of stamps Chris has.

as per the given condition: Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his.

"3 times the number of stamps Chris has" means 3r

"6 less than 3 times number of stamps Chris has" which means subtract 6 from 3r i,e 3r -6

therefore, the expression 3r -6 represents the number of stamps Erykah has.

Please help me with this question. I don't think I understand it. Quadratic functions graphing #15-19.
belka [17]

Answer:

15) (1, 1) and (-1, 1)

16) (1, 2) and (-1, 2)

17 (1,1/2) and (-1, 1/2)

18) (1,1/4) and (-1, 1/4)

19) 16 is vertical stretch, 17 and 18 is vertical compressed

Step-by-step explanation:

for qs 15-18 since x is 1 or -1 if you sq 1 or -1 you will always get 1

so y is the "a" value in the equation  y=ax²

for qs 19

y=ax²

so if a>1 -- then vertical stretch

when 0<a<1 -- then vertical compressed
