Answer:

1/16

Step-by-step explanation:

There is a 50% chance of it being a boy or a girl also known as 1/2

So the first baby has a 1/2 chance, same for the second, and third, Which means that there is a 1/2, then another 1/2 and another 1/2. So you would have to multiply them all, 1/2*1/2*1/2 = 1/8. For the girl, again, it is 1/2 chance of being a girl, while the other 1/2 is a boy. So 1/8*1/2 is 1/16. So the probability so the women having 3 boys then a girl, is 1/16.

Hope this helps

Given

The total no of beads is 52

there 13-red,13-blue,13-green, and 13-black

Solve these equations.<br> |x-7|=x-7
Cloud [144]

Answer:

x ≥ 7

Step-by-step explanation:

|x - 7| = x - 7

A. For each absolute, find the intervals

x - 7 ≥ 0     x - 7 < 0

     x ≥ 7           x < 7

If x ≥ 7, |x - 7| = x - 7 > 0.

If x < 7, |x - 7| = x - 7 < 0. No solution.

B. Solve for x < 7

Rewrite |x - 7| = x - 7 as

+(x - 7) = x - 7

      x - 7 = x - 7

-x + 14 = x

        14 = 2x

          x = 7

7 ≮7. No solution

C. Solve for x ≥ 7

Rewrite |x - 7| = x - 7 as

+(x - 7) = x - 7

      x - 7 = x - 7

True for all x.

D. Merge overlapping intervals

No solution or x ≥ 7

⇒ x ≥ 7

The diagram below shows that the graphs of y = |x - 7| (blue) and of y = x - 7 (dashed red) coincide only when x ≥ 7.

Which polynomial is a product of (3x+2) and (x-7)
pogonyaev

(3x+2)  (x-7)

FOIL

first 3x*x  = 3x^2

outer  3x*-7 = -21x

inner = 2*x = 2x

last  2*-7 = -14

add them together  = 3x^2 -21x+2x -14

combine like terms  3x^2 -19x -14
