Subtract 8/10 from 4/10 but just the numerator (the top number) and you will get 4/10
Since the ratio of girls and boys must be the same in each team, and all the competitors must be involved, it means that each team's ratio of boys : girls must be equal to the total ratio of Boys : Girls = 36 :27= 4 / 3.
Now 4 / 3, the most simplified version of 36 / 27, happens by dividing the numerator & demoninator by 9 (the greatest number it can divide by). So the greatest number will be 9 teams, each of 4 Boys & 3 Girls
The last one is the answer
Answer:
r/n
22.91%
33.33%
Step-by-step explanation:
To calculate the experimental probability, we must divide the number of times the event occurred by the total number of events, that is:
r / n
r = 11, n = 48
11/48 = 0.2291
In other words, the experimental probability is 22.91%
for the theoretical probability it would be the quantity that there is of that object among the total quantity of objects, in this case it would be:
1/3 = 0.3333
that is, the probability is 33.33%
Answer:
x = 54
y = 114
Step-by-step explanation:
y = 114 because of the Corresponding Angles Theorem:
"If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent."
(x + 12) + y = 180
x + 12 + 114 = 180
x + (126 - 126) = (180 - 126)
x = 54
Quick Check:
54 + 12 + 114 = 180 ✔
