X= 4. You get this by setting the two equations equal to each other and isolating the variable and the constant.
Add both sides by 16
so you'll have x^4 =16
take the 4th root of both sides and you'll get x= 2
Answer:
12
Step-by-step explanation:
5 : 6 = Number of boys to girls
(We have to ×2 to get from 5 to 10 so we must ×2 from 6 to 12)
10 : ? = Number of Boys to girls
10 : 12 = Number of Boys to girls
Answer:
B) 3/4
Step-by-step explanation:
The conditional probability of B given A (B|A) is P(A ∩ B) / P(A), when P(A) > 0 (Probability of the intersection of A and B over the Probability of A).
in our case, P(A ∩ B is the amount of people who can snowboard and surf, which according to the picture is 36
P(A) is the amount of people who can snowboard, which from the picture is 48
This means our conditional probability is 36/48, which when simplified is 3/4.
