Since a whole recipe asks for 4 1/2 pounds of chicken, then for a 1/2 recipe, you divide 4 1/2 by 2.
It’s easier to turn 4 1/2 to 4.50
4.50/2 = 2.25 or 2 1/4
You need 2 1/4 pounds of chicken for 1/2 of a recipe.
Answer:
a) 0.1108
(b) 0.0173
Step-by-step explanation:
We are given that 20% of all stock investors are retired people. A random sample of 25 stock investors is taken.
Firstly, the binomial probability is given by;
where, n = number of trails(samples) taken = 25
r = number of successes
p = probability of success and success in our question is % of
retired people i.e. 20%.
Let X = Number of people retired
(a) Probability that exactly seven are retired people = P(X = 7)
P(X = 7) =
= = 0.1108
(b) Probability that 10 or more are retired people = P(X >= 10)
P(X >= 10) = 1 - P(X <= 9)
Now, using binomial probability table, we find that P(X <= 9) is 0.98266 at n = 25, p = 0.2 and x= 9
So, P(X >= 10) = 1 - 0.98266 = 0.0173.
That’s an acute triangle since all angles seem less then 90 degrees
