A drawer contains 4 pairs of blue socks, 5 pairs of white socks, and 3 pairs of gray socks. If a pair of socks is randomly chosen, what is the probability it is gray?

A) 30%

B) 0.3

C) 0.25

D) 3

0.25

Step-by-step explanation:

Number of pairs of blue socks = 4

Number of pairs of white socks = 5

Number of pairs of gray socks = 3

Total pairs of socks= 4 + 5 + 3 = 12

Probability of choosing gray socks will be the number of gray socks divided by the total number of pairs of socks. This will be:

P( choosing gray) = 3/12

= 0.25

C) 0.25

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, we have that:

There are 4+5+3 = 12 socks.

Of those, 3 are are gray.

3/12 = 0.25.

So the correct answer is:

C) 0.25

the answer to this question is yes

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
