Answer:
1. 0.1684 = 16.84%.
2. 0.2568 = 25.68%
3. 0.0013 = 0.13%
4. 0.0126 = 1.26%.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have blood that is Group O, or they do not. The probability of a person having blood that is Group O is independent of any other person, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
45% of them have blood that is Group O
This means that
Question 1:
This is P(X = 6) when n = 16. So
So 0.1684 = 16.84%.
Question 2:
This is P(X = 3) when n = 8. So
So 0.2568 = 25.68%.
Question 3:
This is P(X = 16) when n = 20. So
So 0.0013 = 0.13%.
Question 4:
This is P(X = 9) when n = 11. So
So 0.0126 = 1.26%.
Answer:
Step-by-step explanation:
<h3>Question 12)</h3>
<u>Slope between the points:</u>
- A(a + b, 4m - n) and B(a - b, m + 2n)
<u>Use slope formula:</u>
- Slope = (m + 2n - 4m + n)/(a - b - a - b) =
- (-3m + 3n)/(-2b) =
- (-3)(m - n)/(-2)b
- 1.5(m - n)/b
<h3>Question 13)</h3>
<u>Slope between the points:</u>
- C(3c - d, s + t) and D(c - 2d, s - t)
<u>Use slope formula:</u>
- Slope = (s - t - s - t)/(c - 2d - 3c + d) =
- (-2t)/(-2c - d) =
- (-2)t/(-1)(2c + d)
- 2t/(2c + d)
Answer:
F(x) = 4x - 16
Step-by-step explanation:
G(x) = 4x
if F(x) is the graph G(x) shifted over to the right by 4 then
F(x) = G(x-4) = 4(x-4) = 4x - 16
The general equation is f(x - <em>amount_shifted</em>)
