Answer:
0.1348 = 13.48% probability that 3 of them entered a profession closely related to their college major.
Step-by-step explanation:
For each graduate, there are only two possible outcomes. Either they entered a profession closely related to their college major, or they did not. The probability of a graduate entering a profession closely related to their college major is independent of other graduates. This, coupled with the fact that they are chosen with replacement, means that we use the binomial probability distribution 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.
53% reported that they entered a profession closely related to their college major.
This means that
9 of those survey subjects are randomly selected
This means that
What is the probability that 3 of them entered a profession closely related to their college major?
This is P(X = 3).
0.1348 = 13.48% probability that 3 of them entered a profession closely related to their college major.
<span>The proper fraction is c. 3/4. A proper fraction is a fraction that is less than one. A fraction is less than one if its denominator, the number below the line, is larger than its numerator, the number above the line. 4/3 and 7/6 are both greater than one and 4/4 is equal to one, thus none of them are proper fractions.t</span>
Answer:
slope = -
Step-by-step explanation:
Parallel lines have equal slopes thus the slope of a parallel line will be equal to the slope of PQ
To calculate slope m use the slope formula
m =
with (x₁, y₁ ) = P(- 2, 4) and (x₂, y₂ ) = Q(6, - 2)
m = = = -
