One is 17.22 and the other is simply 2.
The ration of boy campers to total campers is 8:15, and the ratio of girl campers to total campers is 7:15. Using this information, we can answer this question by setting up proportions.
<u>For boys:</u>
<em>*Cross multiply*</em>
15x=1560
<em>*Divide both sides by 15*</em>
x=104
There are 169 boy campers.
<u>For girls:</u>
<em>*Cross multiply*</em>
15x=1365
91=x
There are 91 girl campers.
Hope this helps!!
Answer:
Step-by-step explanation:
<u>Total number of marbles:</u>
<u>There are two possibilities</u>
- Orange then green or green the orange
<u>The probabilities are:</u>
- P(o&g) = 2/10*2/9 = 2/45
- P(g&o) =2/10*2/9 = 2/45
<u>Required probability is:</u>
- P = 2/45*2 = 4/45 = 0.08889
Correct choice is C
Note that 8.00 = (2.00)^3, that implies that a decay to 1/8.00 means that the Carbon-14 has passed 3 half-life. (1 to decay to 1/2, other to decay to 1/4, and other to decay to 1/8). And, three half-life is 3 * 5730 years = 17,920 years. So,<span> the answer is that the plant was alive 17,920 years.</span>
Y=mx+b is this what you want
