Answer:
B) 17.1
Step-by-step explanation:
g = 5
f = 5
That means we have a 45-45-90 triangle
and the hypotenuse =
times the length of a leg
Therefore, h = 5
= 7.1
5 + 5 + 7.1 = 17.1
Note: If you have not been taught about 45-45-90 triangles, then use the Phythagorean theorem. OK?
The radius of circle is 3.5 only
Answer:
11 meters plus
Step-by-step explanation:
you plus it
The reason why the sum of your probabilities equals 0.5 is because you're only considering half of the problem--i.e. the probabilities for only one gender. For example, the probability that there are only three children and all are boys is 1/8. But, remember, it could be the case that there are three children and all are girls. Thus, the probability that there are three children is 1/4--not 1/8. Thus, multiply your result for P(X=4) and P(X=5) by 2 and you should end up with the right answer...
