This is an equilateral triangle (as shown by the markings), therefore all sides have equal length.

XZ = ZY
$\frac{1}{2} x + 8 = 2(x - 8)$
$\frac{1}{2} x + 8 = 2x - 16$
$\frac{1}{2} x + 24 = 2x$
$24 = 1.5 x$
$x = 16$

The following frequency table summarizes the number of children that dads in Dads Club have.

attashe74 [19]

Answer:

Step-by-step explanation:

Now there are 6+4+8+1+1=20 dads in the Dads Club.

Fewer than 3 children have

1 child - 6 dads
2 children - 4 dads.

So, 6+4=10 dads have fewer than 3 children.

The probability that the dad of Dads Club has fewer than 3 children is

$Pr=\dfrac{10}{20}=0.5 \text{ or } 50\%.$

The probability that the next dad to join Dads Club has fewer than 3 children is reasonable to be 50%.
