Answer:
p = 0.513
Step-by-step explanation:
There are 212 families with exactly 3 children. So in all, there are 212*3 = 636 children.
Of those,
The number of girls is:
81 + 76*2 + 31*3 = 326
That is, 326 girls out of 636 children.
Then

1. N=x+3
S=2(x+3), or Sam=2x+6
Answer:
Step-by-step explanation:
Simplify -12\ 4−12÷4 to -3−3.
-3=-3-8-48,3
−3=−3−8−48,3
2 Simplify -3-8−3−8 to -11−11.
-3=-11-48,3
−3=−11−48,3
3 Simplify -11-48−11−48 to -59−59.
-3=-59,3
−3=−59,3
4 Since -3=-59,3−3=−59,3 is false, there is no solution.
