2 A family is planning on having two children. Assume that it is equally likely for each child to be a boy or a girl. Which of these statements are true?
Choose all that apply.
A The theoretical probability of the first child being a boy is greater than the
theoretical probability of the second child being a girl.
B If the first child is a boy, the theoretical probability that the family will have
a boy and a girl is equal to
C If the first child is a boy, the theoretical probability of the second child also being
a boy is greater than the theoretical probability of the second child being a girl.
DIf the first child is a girl, the theoretical probability that the family will have
two girls is equal to the theoretical probability that the family will have one girl
and one boy.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

it would open into a square depending on the type of envelope i’m not sure about the second part

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
