Answer: Choice B) 
(y+5)+y = 6

----------------------------------------------------------------

So what we do is start with x+y = 6. We can replace the 'x' with (y+5). This replacement is possible because x = y+6; ie x and y+6 are the same. Another term for "replace" is "substitute"

This is how we're able to go from x+y = 6 to (y+5)+y = 6

Find the indicated probability by using the complementation rule. A percentage distribution is given below for the size of famil
arlik [135]

Answer:

The correct option is c.

Step-by-step explanation:

The percentage probability distribution is:

Size (X)      Percentage

 2                   39.9

 3                   24.4

 4                   20.1

 5                   10.8

 6                    3.3

 7                     1.5

Total             100.0

Compute the probability that the size of the family is 4 or more as follows:

P (X ≥ 4) = P (X = 4) + P (X = 5) + P (X = 6) + P (X = 7)

              = 0.201 + 0.108 + 0.033 + 0.015

              = 0.357

Thus, the probability that the size of the family is 4 or more is 0.357.

The correct option is c.

Write an equation if the line that passes through (0,-3) and (3,3) .
liq [111]

Answer:

y = 2x - 3

Step-by-step explanation:

y = mx + b

m = (y2-y1)/(x2-x1)

m = (3-(-3))/(3-0)

m = 6/3

m = 2

y = mx + b

y = 2x + b

3 = 2(3) + b

3 = 6 + b

b = -3

therefore

y = 2x - 3
