Replace t with the months given as choices to see which one gives a positive value as an answer.

P(1) = 1^4-9(1)^3 + 24(1)^2-20(1) = -4

P(2) = 2^4-9(2)^3+24(2)^2-20(2) = 0

P(3) = 3^4 -9(3)^3+24(3)^2-20(3) = -6

P(5) = 5^4-9(5)^3+24(5)^2-20(5) = 0

P(6) = 6^4-9(6)^3+24(6)^2-20(6) = 96

It shows a profit in month 6 so it would start showing a profit in month 5.

The answer is 5 months

What do you add to 2 1/8 to make 4

barxatty [35]

Step-by-step explanation:

Let us add x to $2\frac{1}{8}$ to make 4.

$\therefore \: x + 2 \frac{1}{8} = 4 \\ \\ \therefore \: x + \frac{2 \times 8 + 1}{8} = 4 \\ \\ \therefore \: x + \frac{16 + 1}{8} = 4 \\ \\ \therefore \: x + \frac{17}{8} = 4 \\ \\ \therefore \: x = 4 - \frac{17}{8} \\ \\ \therefore \: x = \frac{4 \times 8 - 17}{8} \\ \\ \therefore \: x = \frac{32- 17}{8} \\ \\ \therefore \: x = \frac{15}{8} \\ \\ \therefore \: x =1 \frac{7}{8} \\ \\ \therefore \:1 \frac{7}{8} \: should \: be \: added \: in \: 2 \frac{1}{8} \: to \: \\ \: \: \: \: \: make \: it \: \: 4.$

You are going to meet a friend at the airport. Your experience tells you that the plane is late 70% of the time when it rains, b

Feliz [49]

Answer:

0.4

Step-by-step explanation:

Probability of rain = P(R)

Probability of late plane = P(L)

So, the probability of no rain = P(R')

Breaking it down

If it rains, 40% chance, P(R) = 0.4

That the plane would be late if it rains = 70% × 40%, that is, P(R n L) = 0.7 × 0.4 = 0.28, 28% of the total chance.

That the plane would be on time if it rains = 30% × 40%, that is, P(R n L') = 0.3 × 0.4 = 0.12, 12% of the total chance.

If it doesn't rain, 60% chance, P(R') = 1 - P(R) = 1 - 0.4 = 0.6

That the plane would be late if it doesn't rain = 20% × 60%, that is, P(R n L') = 0.2 × 0.6 = 0.12, 12% of the total chance.

That the plane would be on time if it doesn't rain = 80% × 60%, that is, P(R' n L') = 0.8 × 0.6 = 0.48, 48% of the total chance.

So, probability that the plane would be late = P(L) = P(R n L) + P(R' n L) = 0.28 + 0.12 = 0.4 = 40%
