there are 16 socks in the drawer

probablility of 2 white socks  or  2 black socks

6/16 *5/15  + 10/16*9/15   no replacement on socks

30/240 + 90/240

120/240

|\Omega|=C(16,2)=\dfrac{16!}{2!14!}=\dfrac{15\cdot16}{2}=120\\|A|=C(6,2)+C(10,2)=\dfrac{6!}{2!4!}+\dfrac{10!}{2!8!}=\dfrac{5\cdot6}{2}+\dfrac{9\cdot10}{2}=15+45=60\\\\P(A)=\dfrac{60}{120}=\dfrac{1}{2}=50\%

3) Y-3=4(n=2)<br>*to draw graph​​​​
Kazeer [188]

Answer:

[see below]

Step-by-step explanation:

I am assuming that you mean: y-3=4(x-2).

The equation is in point slope form...

y-y_1=m(x-x_1)

The point used in the equation is (2, 3). 2 replaces 'x1' and 3 replaces 'y1'.

If you convert the equation in to slope intercept form:

y-3=4(x-2)\\\\y-3=4x-8\\\\y-3+3=4x-8+3\\\\\boxed{y=4x-5}

You get -5 as the y-intercept.

So, the line you draw would pass through points (2,3) and (0,-5).

Hope this helps.

A farmer finds that if she plants 60 trees per acre, each tree will yield 45 bushels of fruit. she estimates that for each addit
Mkey [24]
Answer: 60 trees

Explanation: 
Even if there are trees planted per acre, the decrease of yield of each tree is significant enough to make it less worthwhile to have more trees than less. 

In other words, when she plants 60 trees per acre, she gets 2700 bushels of fruit per acre, because 45 bushels per tree = 45 • 60 = 2700. If you plant another tree, you get the equation 41 • 61 = 2501 because there are 4 less bushels per tree. 2501 < 2700 so 60 per acre would maximize the harvest.
