A. That would be 12C4 = (12*11*10*9) / (4*3*2*1) = 495 ways
b. This is 7C4 = 7C3 = (7*6*5) / 6 = 35 ways
c. This would come to 7C4 / 12C4 = 35/495 = 7/99
Here, you must find the GCF of 24 and 40 which is 8
Answer:
44%
Step-by-step explanation:
<u> 11 </u> = <u> x </u>
25 100
'percent' means <u>out of 100</u>
25 x 4 = 100
11 x 4 = 44
Answer:
b
Step-by-step explanation:
area of triangle = 1/2 x c x d =cd/2
area of semicircle = 1/2 x π x r^2 = 1/2 x π x (a/2)^2 = 1/2 x π x a^2/4 =πa^2/8
area of shape = area of triangle + area of semicircle
-7255095 is the ans in think so
