1 answer:
Makovka662 [10]3 years ago
7 0

Step-by-step explanation:

There are 21 socks in total. Only 7 of them are white.

When you pick your 1st sock, you have a 7/21 chance to get white.

When you pick your 2nd sock, you have a 6/21 chance to get another white, since you already picked a white.

So the probability to get a pair of white socks is 2/21.

emmainna [20.7K]

Answer:

y = 2M - x  

Step-by-step explanation:

-2(bx-5)=16<br> The value of x in terms of b is?<br> That value of x when b is 3?
grin007 [14]

Answer:

Step-by-step explanation:

Let's solve for b.

−2(bx−5)=16

Step 1: Add -10 to both sides.

−2bx+10+−10=16+−10

−2bx=6

Step 2: Divide both sides by -2x.

−2bx/−2x=6/−2x

b=−3x

Answer:

b=−3x

———————————————————

Let's solve for x.

−2(bx−5)=16

Step 1: Add -10 to both sides.

−2bx+10+−10=16+−10

−2bx=6

Step 2: Divide both sides by -2b.

−2bx/−2b=6/−2b

x=−3b

Answer:

x=−3b

Hope this helps you out

a truck costing 25000 with a residual value of 5000. the truck's estimated life is 10 years. what is the book value at the end o
sineoko [7]
$25,000 - 5,000 = $20,000
Since the useful life is 10 years or 10% per year, double-declining rate would be 20%

Year 1
$20,000 x .2 = $4000
Book Value = $16,000

Year 2
$16,000 x .2 = $3,200
Book Value = ($16,000-3,200) =$12,800

Which are the coordinates of the midpoint of JK with endpoints J(-7, -1) and K(13, -6)?
dsp73
The x coordinate of J is -7. The x coordinate of K is 13. The x coordinates add up to -7+13 = 6. Divide this result in half to get 6/2 = 3. Therefore, the midpoint has an x coordinate of 3.

The y coordinate of J is -1. The y coordinate of K is -6. The y coordinates add up to -1+(-6) = -7. Divide this result in half to get -7/2. Therefore, the midpoint has a y coordinate of -7/2.

This is why the final answer is choice D) (3, -7/2)
