Answer:
0% probability that 3 of them have insurance
Step-by-step explanation:
For each American, there are only two possible outcomes. Either they have insurance, or they do not. So 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.
Twenty-percent (20%) of Americans have no health insurance.
This means that 80% have insurance, so
Randomly sample n = 15 Americans.
This means that
What is the probability that 3 of them have insurance?
This is
0% probability that 3 of them have insurance
Answer:
Yolanda had the same number of penalties in both games.
Step-by-step explanation:
Both of these penalties can be modeled by a first order equation.
Game of Meteor-Mania:
In a game of Meteor-Mania, each penalty is -5 seconds. So the expression for the total of penalties is:
Tp(n) = -5*n, where n is the number of penalties.
In the game of Meteor-Mania, Yolanda had penalties totaling -25 seconds. So
-25 = -5*n *(-1)
5n = 25
n = 25/5
n = 5
Yolanda had 5 penalties in the game of Meteor-Mania
Game of Cosmic Calamity
In a game of Meteor-Mania, each penalty is -7 seconds. So the expression for the total of penalties is:
Tp(n) = -7*n, where n is the number of penalties.
In the game of Cosmic Calamity, Yolanda had penalties totaling -35 seconds. So
-35 = -7n *(-1)
7n = 35
n = 35/7
n = 5
Yolanda had 5 penalties in the game of Cosmic Calamity
Yolanda had the same number of penalties in both games.
