Employees that work at a fish store must measure the level of nitrites in the water each day. Nitrite levels should remain lower

than 5 ppm as to not harm the fish. The nitrite level varies according to a distribution that is approximately normal with a mean of 3 ppm. The probability that the nitrite level is less than 2 ppm is 0.0918.
1. Which of the following is closest to the probability that on a randomly selected day the nitrite level will be at least 5 ppm?
(A) 0.0039
(B) 0.0266

A game spinner has regions that are numbered 1 through 8. If the spinner is used twice, what is the probability that the first n
Zina [12379]
Let P(3) denote the probability of landing on 3 in a spin, and P(5) denote the probability of landing on 5. In probability terms, "AND" signifies multiplication while "OR" indicates addition. We aim to find the probability that the first number is "3" AND the second number is "5." Thus, we identify the individual probabilities and MULTIPLY them. The spinner has numbers ranging from 1 to 8, each appearing once. Therefore, since there is one instance of "3," we have P(3) = 1/8 and similarly P(5) = 1/8. Consequently, the overall probability of P(3 and 5) is 1/8 multiplied by 1/8, which equals 1/64.

tester [12383]

Answer:

\boxed{57ft 10in}

Step-by-step explanation:

Hello!

To find the total length when it is 18 feet 3 inches, we must add both lengths:

18ft 3in + 18ft 3in = 36ft 6in

For the width, add: 10ft 8in + 10ft 8in = 20ft 16in, which converts to 21ft 4in

Therefore, l + w = 57ft 10in

I hope this is helpful:)

Zina [12379]
Assuming that the departure day for both is day 0, Sandy's next day off occurs on day 4, while Morgan's falls on day 10. Sandy's days off will be on days 4, 8, 12, 16, and 20. Meanwhile, Morgan's days off will be on days 10, 20, 30, 40, and 50. Thus, both of them will share a day off on day 20, meaning they will next have a joint day off in 20 days.
