I need choices so i can see which one is right
Answer:
P(spin a multiple of 3 = 1/3
Step-by-step explanation:
multiple of 3 = 3,6,9,12
P(spin a multiple of 3) = 4/12 = 1/3
Answer:
The probability that between 79% and 81%of the 500 sampled wildlife watchers actively observed mammals in 2011 is P=0.412.
Step-by-step explanation:
We know the population proportion π=0.8, according to the 2011 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation.
If we take a sample from this population, and assuming the proportion is correct, it is expected that the sample's proportion to be equal to the population's proportion.
The standard deviation of the sample is equal to:
With the mean and the standard deviaion of the sample, we can calculate the z-value for 0.79 and 0.81:
Then, the probability that between 79% and 81%of the 500 sampled wildlife watchers actively observed mammals in 2011 is:
13).
(600 ft / 5 min) x (1min / 60sec)
= (600 · 1 / 5 · 60) (ft · min / min · sec)
= 2 ft/sec
______________________________
14).
(120 yd / 2 min) x (3ft / 1yd) x (1min /60 sec)
= (120 · 3 · 1 / 2 · 1 · 60) (yd · ft · min / min · yd · sec)
= 3 ft/sec

15).
(60 mile /1 hour) x (5,280ft / 1mile) x (1hr / 3,600sec)
= (60 · 5,280 · 1 / 1 · 1 · 3,600) (mile · ft · hour / hour · mile · sec)
= 88 ft/sec .
147 is not a perfect square. The reason 147 is not a perfect square is because, we know that 144 is a perfect square because you can divide it by 12. So that means that your square root would be inbetween 12 and 13. If you multiple 12•12 you get 144. And if you multiply 13•13 you get 169. So neither of those numbers are equal 147 so 147 is NOT a square but the closest square root is 12.
