Answer 5

lily

Answer 6

\[\large\rm \frac{ number ~of~red~chocolates }{total~number~of~chocolates }\]
remember there are total 10 are red
and we have already picked one red

Answer 7

the total number of chocolates in the bag before you take any out is 38.
since you the problem says that you've removed 1 red
you now have 9 red and a total of 38-1 in the bag.

so 9/37

Answer 8

ok

Answer 9

these and two more questions lily

Answer 10

for #22 For the function f(x) = -2x2, if the domain is {-3, 0, 3}, find the range.

since f(x) = y and domain is = x you can find the range by doing -2(-3)2, -2*0*2, -2*3*2

Answer 11

sorry I just saw that you meant it as -2x^2 ... anyway just plug in the values you have for x into -2x^2 and you'll get your range

Answer 12

(-18,0,-18) or (0,-18)

Answer 13

for 21) is m4/2r3/2 the same as \[m\frac{ 4 }{ 2 }r \frac{ 3 }{ 2 }\] ? if not, then I am not sure how to read it.

Answer 15

2ndly we are not here to do their work but to guide them
you are really good at explaining no doubt. i think it would be great if you let them do some work like adding/plugging in numbers instead doing on your own.
