<em>Complete Question:</em>

In a jar there are 19 red jelly beans and 10 green jelly beans. In how many ways can you pick 4 red jelly beans and the same number of green jelly​ beans?

Answer:

Both = 813960

Step-by-step explanation:

Given

Red Jelly Beans = 19

Green = 10

Required

Select 4 out of 19 red jelly beans and 4 out of 10 green jelly beans

The keyword in the question is pick and this implies combination;

4 from 19 red jelly beans is calculated as follows

^nC_r = \frac{n!}{(n-r)!r!}

Where n = 19 and r = 4

^{19}C_4 = \frac{19!}{(19-4)!4!}

^{19}C_4 = \frac{19!}{15!4!}

^{19}C_4 = \frac{19 * 18 * 17 * 16 * 15!}{15! * 4 * 3 * 2 * 1}

^{19}C_4 = \frac{19 * 18 * 17 * 16}{4 * 3 * 2 * 1}

^{19}C_4 = \frac{93024}{24}

^{19}C_4 = 3876

Similarly;

4 from 10 green jelly beans is calculated as follows

^{10}C_4 = \frac{10!}{(10-4)!4!}

^{10}C_4 = \frac{10!}{6!4!}

^{10}C_4 = \frac{10 * 9 * 8 * 7 * 6!}{6! * 4 * 3 * 2 * 1}

^{10}C_4 = \frac{10 * 9 * 8 * 7 }{4 * 3 * 2 * 1}

^{10}C_4 = \frac{5040}{24}

^{10}C_4 = 210

Ways of selecting both is calculated as follows

Both = 3876 * 210

Both = 813960

Serga [27]

Explanation:

The slope of the line is found by the method: rise/run

You calculate how much the slope rises(goes up) and divide it by run(goes horizontal).

One more thing to note is that: the slope is negative BECAUSE ITS DECREASING.

Your answer:   -3/2

Slope form: y=mx + b
slope is 2/5, fill into equation
Y = 2/5x + b
Plug in point to find b
1 = 2/5(0) + b
1 = 0 + b, b = 1
The answer is A. Y = 2/5x + 1
