Step-by-step explanation:
You simply convert the decimal.
Sounds like a problem in binomial probability. What do you think?
Here the # of experiments is 6, so n = 6. The probability of a baby girl being born is 0.50.
Using my TI-83 Plus calculator:
binompdf(6, 0.5, 2) = 0.234
binompdf(6, 0.5, 3) = 0.313
binompdf(6, 0.5, 4) = 0.234
binompdf(6, 0.5, 5) = 0.094
binompdf(6, 0.5, 6) = 0.016
To get the prob. of at least 2 girls in 6 births, add up the 5 probabilities given above:
P(at least 2 girls in 6 births) = 0. ???
20% = 0.20
6 * 0.20 = 1.2
6 + 1.2 = 7.2
Circle B has a radius of 7.2.
Circle Area = pi *r^2
Lets use 3.14 for pi
3.14 * 7.2^2 = Area of circle B
7.2 * 7.2 = 51.84
3.14 * 51.84 = 162.7776
Area of circle B is 162.7776
Rounded to 2 decimals, this is 162.78
A. 189.31
D. 162.78
E. 203.15
are all equal to or grater than 162.78
Answer:
The answer is 0.23

Hope this helps.
Pls tell me if Im not correct.
Answer:
3 : 4 = 12 : 6
2 : 5 = 30 : 75
7 : 9 = 14 : 18
8 : 3 = 64 : 24
Step-by-step explanation:
3 : 4 = 12 : ?
3/4 = 12/?
3 x ? = 12 x 4
3 x ? = 48
? = 48 ÷ 3 = 16
2 : 5 = 30 : ?
2/5 = 30/?
2 x ? = 30 x 5
2 x ? = 150
? = 150 ÷ 2
? = 75
7 : 9 = ? : 18
7/9 = ?/18
7 x 18 = ? x 9
126 = ? x 9
? = 126 ÷ 9
? = 14
8 : 3 = 64 : ?
8/3 = 64/?
8 x ? = 64 x 3
8 x ? = 192
? = 192 ÷ 8
? = 24
