Answer:
20 students in science class, 25 in math
Step-by-step explanation:
so let 1 classroom= x
so the other classroom= x+5
if there is a total of 45 students
x+x+5=45
2x=45-5
2x=40
x=20
Answer:
a. .0125
Step-by-step explanation:
For each part, there are only two possible outcomes. Either it is defective, or it is not. The probability of a part being defective is independent of any other part. This 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.
2% defective parts.
This means that 
A sample of nine parts from the production process is selected.
This means that 
What is the probability that the sample contains exactly two defective parts?
This is P(X = 2).
0.0125 = 1.25% probability that the sample contains exactly two defective parts. The correct answer is given by option a.
Answer:
11 units
Step-by-step explanation:
Answer:
Not independent
Step-by-step explanation:
This problem involves independence criteria for conditional probabilities.
The two events will be independent if P(A/B)=P(A) or P(B/A)=P(B)
Let us assumes that event A is for student attending private college and B is for student graduating in four years.
So we are given the following probabilities
P(A)=0.20
P(B)=0.55
P(B/A)=0.79
As we can see that P(B/A)≠P(B) so the events A and B are not independent.
So based on the above results we can say that "attending a private college or university" is not independent of "graduating in four years". Thus the two events "attending a private college or university" and "graduating in four years" are dependent.
B. Collinear
Collinear means that two or more points are on the same line.
