Answer:
1860 WAYS
Step-by-step explanation:
Combination is the technique used to compute the selection of items based on given criteria.
ⁿₐC = n!/(n - a)! a!
The number of ways an 8-person committee of 4 men and 4 women is to be formed from a group of 15 women and 12 men
= 15 ₄C + 12₄C
= 15!/(15 - 4)!4! + 12!/(12 - 4)!4!
= 1365 + 495
= 1860 WAYS

Step-by-step explanation:
Answer:
You're pretty sure that your candidate for class president has about 55% of the votes in the entire school. but you're worried that only 100 students will show up to vote. how often will the underdog (the one with 45% support) win? to find out, you set up a simulation.
a. describe-how-you-will-simulate a component.
b. describe-how-you-will-simulate a trial.
c. describe-the-response-variable
Step-by-step explanation:
Part A:
A component is one voter's voting. An outcome is a vote in favor of our candidate.
Since there are 100 voters, we can stimulate the component by using two random digits from 00 - 99, where the digits 00 - 64 represents a vote for our candidate and the digits 65 - 99 represents a vote for the under dog.
Part B:
A trial is 100 votes. We can stimulate the trial by randomly picking 100 two-digits numbers from 00 - 99.
And counted how many people voted for each candidate. Whoever gets the majority of the votes wins the trial.
Part C:
The response variable is whether the underdog wins or not.
To calculate the experimental probability, divide the number of trials in which the simulated underdog wins by the total number of trials.
Answer:
50 km
Step-by-step explanation:
So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by
2.5
1
. Then, 20 x 2.5=50. So the answer is 50 km
