Miriam is picking out some movies to rent, and she is primarily interested in comedies and foreign films. She has narrowed down her selections to 10 comedies and 15 foreign films. How many different combinations of 3 movies can she rent if she wants at least two comedies?

Answers

Answer:

There are 795 combinations.

Step-by-step explanation:

The number of ways or combinations in which we can select k element from a group of n elements is given by:

$nCk=(n!)/(k!(n-k)!)$

So, if Miriam want to choose 3 movies with at least two comedies, she have two options: Choose 2 comedies and 1 foreign film or choose 3 comedies.

Then, the number of combinations for every case are:

1. Choose 2 Comedies from the 10 and choose 1 foreign film from 15. This is calculated as:

$10C2*15C1=(10!)/(2!(10-8)!)*(15)/(1!(15-14)!)$

$10C2*15C1=675$

2. Choose 3 Comedies from the 10. This is calculated as:

$10C3=(10!)/(3!(10-3)!)=120$

Therefore, there are 795 combinations and it is calculated as:

675 + 120 = 795

To determine customer opinion of their pricing, Home Depot randomly selects 140 check out lines during a certain week and surveys all customers in the check out lines. What type of sampling is used?

Answers

Answer: Cluster sampling

Step-by-step explanation:

A cluster sampling is a kind of random sampling technique in which the researcher splits the whole population into distinct sets known as clusters.

After that, he choose a random sample of clusters from the population and do analysis on it.

In the given situation, the objective of survey : "To determine customer opinion of their pricing:".

He first divides the number of check out lines according to weeks and randomly selects 140 check out lines during a certain week and surveys all customers in the check out lines. .

(Here , check out lines = clusters )

Therefore , the type of sampling is used = Cluster sampling

Cluster sampling is used by Home Depot for a certain week and surveys all customers in the check out lines.

Two equations are given below:m + 4n = 8
m = n − 2

What is the solution to the set of equations in the form (m, n)?

(4, 6)

(2, 4)

(0, 2)

(6, 8)

Answers

Good morning Brainiac

m=n-2

m+4n=8

We need to solve m=n-2 for m

Substitute n-2 for m in m+4n=8

m+4n=8

n-2+4n=8

5n-2=8

Add 2

5n-2+2=8+2

5n=10

Now divide both sides by 5 so we can find the value for n

5n/5=10/5

n=2

Now substitute 2 for n in m=n-2

m=n-2

m=2-2

m=0
