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.

Describe and correct the error in finding DC

sleet_krkn [62]

Answer:

DC = 2

Step-by-step explanation:

The wrong equation was used.

The right equation to use based on the midsegment theorem of a trapezoid is:

MN = ½(AB + DC)

MN = 8

AB = 14

Substitute

8 = ½(14 + DC)

Multiply both sides by 2

8*2 = ½(14 + DC)*2

2*8 = 14 + DC

16 = 14 + DC

16 - 14 = 14 + DC - 14

2 = DC

DC = 2
