Answer:
a. 0.017
b. 0.013
c. 0.021
Step-by-step explanation:
Let p be the probability that a randomly selected man is 65 or older
And q be the probability that a randomly selected woman is 65 or older
Then p=0.114 and q=0.146
Using the multiplication rule for independent events:
a. If a man is selected at random and a woman is selected at random, the probability that both people selected are 65 or older is p × q = 0.114 × 0.146 ≈ 0.017
b. If two men are selected at random, the probability that both of them are 65 or older is p × p = 0.114 × 0.114 ≈ 0.013
c. If two women are selected at random, the probability that neither of them is 65 or older is q × q = 0.146 × 0.146 ≈ 0.021
Answer: 200 miles per hour
Step-by-step explanation:
200miles per 60 minuets
1/2 hour = 30 minuets
200/0.5 = 100
Therefore, to travel 100 miles in 1/2 an hour you would have to be going 200 miles per hour.
Answer:
70 times
Step-by-step explanation:
There is always a 50-50 chance on which side the coin can land, so on average, the coin lands 70 times on tales, and 70 times on heads.
Maybe make a chart or graph showing that information?
Answer:
8b is 220
Step-by-step explanation:
it might be 220 because we already know that from o to b is 140 degrees. We know that a full circle is 360, so take 140 away from 360, and you get 220.
360-140=220 degrees
Im not sure about the other questions but i hope this helps :)
