Answer:
Step-by-step explanation:
Let x = Time taken <em>(in days)</em> by Jean to do the job.
Then, Time taken by Kate to do the job = x-5
Then, together they will take time (t) as
.
Since it is given that Kate and Jean paint a house together in 6 days.
i.e.
So, the equation represents the time it takes Kate to paint the house by herself is .
A, “the graph passes the vertical line test.”

Answer:
2/9 is the correct option.
Step-by-step explanation:
As the spinner is numbered 2, 4 and 5
The general formula for probability :
P(A) = n(A) / n(S)
n(S) is the number of whole states occur in two spins which is 3 × 3 = 9
n(A) is the event that Rico will get a product of 20.
n(A) = 2 ∵ 4 × 5 and 5 × 4 will bring the product 20.
Therefor, the probability that Rico will get a product of 20 when Rico spins the spinner twice will be:
P(A) = n(A) / n(S)
= 2/9
Therefore, 2/9 is the correct option.
