Answer:
u hv to shade 3 rectangles
Step-by-step explanation:
Answer:
To find the area of a circle you use the formula 
r is the radius so plug that in.
if you only have the diameter, just divide that number by 2 to get the radius
<h3>Answer: 1/6</h3>
====================================================
Explanation:
There are two methods to approach this type of problem.
-------------------------------------
Method 1
A = junior
B = girl
P(A) = probability of selecting a junior
P(B) = probability of selecting a girl
P(B) = (number of girls)/(number total)
P(B) = (4+7+3+4)/(4+4+5+7+2+3+1+4)
P(B) = 18/30
P(B) = 9/15
P(A and B) = probability of selecting a girl who is a junior
P(A and B) = (number of girl juniors)/(number total)
P(A and B) = 3/30
P(A and B) = 1/10
P(A given B) = P(A and B)/P(B)
P(A given B) = (1/10) divided by (9/15)
P(A given B) = (1/10) times (15/9)
P(A given B) = (1*15)/(10*9)
P(A given B) = 15/90
P(A given B) = 1/6
-------------------------------------
Method 2
This method doesn't involve dividing two fractions which could get messy, which is why I find this the easier route. Since we are given the person is a girl, this means we only need to focus on the "girls" column. There are 3 who are juniors out of 4+7+3+4 = 18 total. The probability of selecting a girl junior is 3/18 = 1/6
Very technically, yes. But . . .
-- Its angles would be 0°, 0°, and 180° .
-- Its height and area would both be zero.
-- It would look like a line segment, because the two ' 6 ' legs
would have to be wide open in a straight line, and they would
lie right on top of the ' 12 ' leg ... that's the only way they could
reach between the ends of it.
