Answer:
Probability that a house has a hot tub given that it has a pool is 55%.
Step-by-step explanation:
We are given that in New York State, 38% of the houses have a pool and 21% of the houses have both a pool and a hot tub.
Let the probability that houses have a pool = P(A) = 0.38
Also, let B = event that houses have a hot tub
Probability that houses have both a pool and a hot tub = 
= 0.21
Now, the conditional probability that a house has a hot tub given that it has a pool is given by = P(B / A)
<u>As we know that</u>; P(B / A) = 
= 
= 0.553 ≈ 55%
Hence, the probability that a house has a hot tub given that it has a pool is 55%.

Answer:
4.86
Step-by-step explanation:
Melanie uses 8.1 pints of blue paint and white paint for her bedroom
2/5 of this amount is blue paint
Therefore the amount of white paint can be calculated as follows
= 2/5
= 0.4×100
= 40%
60/100 × 8.1
= 0.6 × 8.1
= 4.86
Hence 4.86 pints of white paint will be used to paint the bedroom
Answer: y = 7
Step-by-step explanation:
Step 1) plug in 3 for y and 9 for x in the direct variation formula, which is y = kx
3 = k(9)
Step 2) Solve for k
3 = k(9) (Divide by 9 on both sides)
3/9 = k (Now simplify 3/9)
1/3 = k. So k = 1/3
*just FYI: “k” is the constant of variation.
Step 3) use the equation y = kx and plug in 1/3 for k
y = 1/3x
Step 4) using the equation y = 1/3x, plug in 21 for x.
y = 1/3(21) (1/3*21 is the same as 21/3)
y = 21/3 (21/3 = 7)
y = 7. So that’s you’re answer! When x=21, y=7 because 7 is 1/3 of 21!
Hope this helps! My best wishes to you as you go through school!
Number one is more likely to happen.
how likely is it? equally likely as not likely
