Svet_ta [14]4 years ago
7 0

Answer:

Step-by-step explanation:

11C4 = 11! / (7!*4!) = 11 * 10 * 9 * 8 * 7!/ 7! * 4!

11C4 = 11*10 * 9 * 8 / 24

11C4 = 11*10 * 3

11C4 = 330

You can't do the second one. Permutations and Combinations always give an answer greater than 1 and integers.

How many times can 8 go into 60
nignag [31]

The correct answers are:

(1) If EXACT number is required, then 7.5.

(2) If multiple of 8 is required then the answer will be 7 times with a remainder of 4.

Explanation:

First you need to express it in the form of equation to make things simpler as follows:

8 * y = 60

We need to find y; to do so, divide 60 by 8:

y = \frac{60}{8}

y = 7.5

Now if you want to find the whole number, then the answer will be 7 times, with 4 left over.

What is the equation of the line that passes through the point (6,−7) and has a slope of -3/2
baherus [9]

Answer:

y = -3/2x + 2

Step-by-step explanation:

slope-line equation : y = mx + b

slope is -3/2

Let's find the y-intercept using (6, -7)

y = mx + b

-7 = -3/2(6) + b

-7 = -18/2 + b

-7 = -9 + b

+9   +9

-----------------------

2 = b

So, y = -3/2x + 2 is your equation.
