Answer:
12 boys
Step-by-step explanation:
boys : girls
4 : 5
Add a total column
boys : girls: total
4 : 5 : 4+5 =9
To get to a total of 27 we multiply each term by 3
boys : girls: total
4*3 : 5*3 : 9*3
12 :15 :27
There are 12 boys
Step-by-step explanation:
every flip has 2 possible outcomes.
1 flip has 2.
2 flips have 2×2 = 2² = 4
3 flips have 2×2×2 = 2³ = 8
and so on.
the number of possible combinations flipping a coin n times is
C(n) = 2^n
for 10 flips
C(10) = 2¹⁰ = 1024
possible outcomes or combinations.
Answer: Hope it helps :)
<u>-4</u>
7
Step-by-step explanation:
You have to use the formula <u>y2-y1</u>
x2-x1
So <u>-4-4</u>
8--6
-4-4= -8
8--6= 14 (two negative signs become a positive sign)
You have -8 over 14
If you simplify it's -4/7 or <u>-4</u>
7
