Answer:
D) P = 8b - 1000
Step-by-step explanation:
Think about it,
First off
If they spent 1000 from just buying the cookies. When you buy something you lose money. So that's -1000.
Secondly,
If they charged $8 per box that would cost an additional eight dollars each time a cutomer perchased a box. Another way to show addition is multiplication.
Ex if someone bought 7 box and 8 dollars each it could be shown as either:
1. 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7
2. 8 + 8 + 8 + 8 + 8 + 8 + 8
3. 7 x 8 or 8 x7
So 8b - 1000 would make the most sense.
12 boxes of pasta packed in an hour and half then boxes packed in 1 hour will be 12/1.5 = 8
thus 8 boxes packed in an hour . this is called the unit rate, so the answer will be 8
3(x-9)=-39
3x-27=-39
+27 +27
3x=-12
/3 /3
x=-4
Answer:
26
Step-by-step explanation:
When you flip two coins, you can have 4 different outcomes:
HH
HT
TH
TT
All outcomes are equally likely, but notice that if you do not keep track of which coin is which, you will get 1/4 of the flips to be both heads, 1/4 of the flips to be both tails, and 1/2 of the flips to be one heads and one tails.
p(both heads) = 1/4
With 105 flips, the expected number of both heads is
105 * 1/4 = 26.25
