Answer:
19.714
Step-by-step explanation:
Given :
Yearly Tuition Frequency
12-16 5
17-21 4
22-26 3
27-31 2
We calculate the midpoint (x) = (lower + upper) / 2
The mean yearly tuition :
The midpoint (x) :
X ___ F ___ Fx
14 __ 5
19 __ 4
24 __ 3
29 __ 2
The mean = Σfx / Σf
Σfx / Σf = (14*5 + 19*4 + 24*3 + 29*2) / (5+4+3+2)
Mean = 276 / 14
Mean yearly tuition = 19.714

Answer:
The probability of all three children being girls is 0.125.
Step-by-step explanation:
The events of a boy being born and the girl being born is equally likely.
That is, P (G) = P(B) = 0.50.
The gender of <em>n</em>th baby born is independent of the gender of the (<em>n</em> - 1)th baby born.
Compute the probability of all girls as follows:
P (All three girls) = P (G) × P (G) × P (G)
![=0.50\times0.50\times0.50\\=0.125](https://tex.z-dn.net/?f=%3D0.50%5Ctimes0.50%5Ctimes0.50%5C%5C%3D0.125)
Thus, the probability of all three children being girls is 0.125.
72 I am guessing because you divide by 3
2x+10=6 can be simplified to 2x=-4
x=-2
