The answer is 6.67 hope this helps :D
23+23+16+16=78
78 is the perimeter:)
C= number of children tickets
a= number of adult tickets
In the equation, $9.50 per ticket must be multiplied by each c and a in order to calculate the total.
($9.50 * c) + ($9.50 * a)
since each term has $9.50 in it, we can pull out the common $9.50 in each
$9.50(c + a)
this expression now means that we must multiply $9.50 by c and then multiply $9.50 by a (using the distributive property)
ANSWER: $9.50(c + a) - the second choice down
Hope this helps! :)
Answer:

Step-by-step explanation:
If the probability of having a boy or a girl is the same, then
the probability of having a boy = a probability of having a girl = 1/2.
Let B denote boy and G denote the girl.
The sample space of having three children is:
BBB, BBG, BGB, GBB, BGG, GBG, GGB, GGG.
The probabilities of each of those events is
