Answer:
5%
Step-by-step explanation:
Hospital A (with 50 births a day), because the more births you see, the closer the proportions will be to 0.5.
Hospital B (with 10 births a day), because with fewer births there will be less variability.
The two hospitals are equally likely to record such an event, because the probability of a boy does not depend on the number of births
Answer:
x=20
Step-by-step explanation:
2x+10=3x-10
Subtract 2x from each side
2x-2x+10=3x-2x-10
10 = x-10
Add 10 to each side
10+10 =x-10+10
20 =x
Answer:
13.5
Step-by-step explanation:
area: 1/2*[x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)]
#10 is A. 7 because each bisector cut each other proportionally
The answer is 20%, the difference is 8 and then divide by 40 then multiply by 100
