Answer:
c. binomial distribution with n = 5 and p = 1/33.
Step-by-step explanation:
For each birth, there are only two possible outcomes. Either it results in a defect, or it does not. The probability of a birth resulting in a defect is independent of other births. So we use the binomial probability distrbution 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.
The proportion of American births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC).
This means that the probability of a birth resulting in a defect is
A local hospital randomly selects five births.
This means that
So the correct answer is:
c. binomial distribution with n = 5 and p = 1/33.

The generic equation of the line is:
y-yo = m (x-xo)
The slope is:
m = (y2-y1) / (x2-x1)
m = (- 2-0) / (3-0)
m = -2 / 3
We choose an ordered pair
(xo, yo) = (0, 0)
Substituting values:
y-0 = (- 2/3) (x-0)
Rewriting:
y = (- 2/3) x
Answer:
The equation of the line is:
y = (- 2/3) x
First find the measure of x.
12x + 3x = 90
15x = 90
x = 6
Plug in x into ∠PVQ, which is 12x.
12(6) = 72
m∠PVQ = 72°
Answer: 300
Step-by-step explanation:
Let the total number of people surveyed be represented by x.
Since we are informed that the probability of a customer ordering chicken is 1/4 and 75 people said they prefer to order chicken. This will then be:
1/4 of x = 75
1/4 × x = 75
x = 75 × 4
= 300
Therefore, 300 people were surveyed
