Answer:

Step-by-step explanation:

The formula for nCk is ...

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

It always works out that nC0 = 1 and nC1 = n, and the sequence of numbers across a row of the diagram is symmetrical about the center.

This means you only need to calculate one value to finish filling your diagram.

4C2 = 4!/(2!(2!)) = (4·3)/(2·1) = 6

You will find the pattern to be ...

each element in the diagram is the sum of the two above it.

I need help like rn plzzzz Laura rents a movie for a flat fee of $2.00 plus an additional $0.50 for each night she keeps the mov

djverab [1.8K]

Answer: c(x) = 2.00 + 0.50x

Step-by-step explanation:

Since they already charged her $2.00 leave that alone. They charge her .50 per night, x represents the number of nights she rented the movie. thus the answer is c(x) = 2.00 + 0.50x.

To find the Median, place the numbers you are given in value order and find the middle number. If there are two middle numbers, you average them.
18, 21, 21, 24, 26, 35, 39, 48

The two middle number are 24 and 26
