Apunnet square is a grid used to show possible gene combinations for the offspring of two parents. in the punnett square shown, a boy is represented by xy. a girl is represented by xx. explain why the probability of two parents having a boy or girl is equally likely.

Probability of having a boy or a girl =

Step-by-step explanation:

In the Punnett square shown, a boy is represented by XY and a girl is represented as XX.

Now total events which can occur n(S) [sample space] = 4

and preferred events of being a baby boy or a girl are n(E) = 2

Therefore, probability of happening a preferred event will be =

Probability =

So Probability of two parents having a boy or girl is 50 : 50

50- 250 is correct i did that one too

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
