Answer:
36
Step-by-step explanation:
1/3 = for every 1 white sock there are 3 black socks
1 times 12 = 12
/ /
3 times 12 = 36
i multiplied 1 times 12 = 12
and 3 times 12 = 36
or you can also do this:
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1+ 1+ 1
3 +3 +3 +3 +3 +3+3+3+3+3+3+3
you can also simplify 12/36 and it will give you 1/3
Answer:
Last on is the answer!! (The relation is a function, and the range is (-2,-1, 1, 3, 4). Hope this helps:)
Answer: " x = 9 " .

Explanation:
____________________________________
To calculate the mean:
____________________________________
The mean =
{the sum of all the values in the number set} ÷
{the number of values in the data set} ;
____________________________________
To solve for "x" ;
____________________________________
Given that the "mean" is: "8" ;
____________________________________
8 = { 3 + 7 + 9 + 12 + x } / 5 ;
____________________________________
↔ { 3 + 7 + 9 + 12 + x } / 5 = 8 ;
____________________________________
→ { 3 + 7 + 9 + 12 + x } = 8 * 5 ;
____________________________________
→ { 31 + x } = 40 ;
____________________________________
↔ x + 31 = 40 ;
____________________________________
Subtract "31" from EACH SIDE of the equation; to isolate "x" on one side of the equation; and to solve for "x" ;
____________________________________
→ x + 31 − 31 = 40 − 31 ;
→ x = 9 .

Let x be a random variable representing the mean weight of a one-year-old Hereford bull. Then
a.) P(x < 1100) = P (z < (X - mean)/sd) = P(z < (1100 - 1150)/80) = P(z < -0.625) = 1 - P(z < 0.625) = 1 - 0.73401 = 0.2660
b.) The middle (50%) of Hereford weights will weigh the mean weight of the sample. i.e. the middle (50%) of the Hereford weights will be 1150 pounds
