A ) equation would be X = Z / Y
B ) if X = 9 ------------> Y = 1/7
X = 21 ----------> Y = ?
21*1/7 = 21/7 , 21/7÷9 = 21*9/7 = 27
so Y equal 27
Answer:
39
Step-by-step explanation:
Angle AQC, AQB and BQC are 120deg. (360/3=120). Therefore, Angle BZC, CXA and AYB are 60deg. Because, angle BZC is half of angle BQC. same for the other three angles. As, all 3 angles are 60deg, it is an equilateral triangle. So, YZ is 13 therefore as all 3 sides are equal its 13*3=39.
Well use photo math that will give u the answer and how to work it out
-9/4, -2.1 , -26/13, -13/8 you can double check by inserting all these into a calculator so u can see in decimal form and basically the bigger the number that’s negative the less value it is (sorry that’s kind of a bad explanation but i hope this helps :) )
If P(A) times P(B) is equal to P(A n B), then that shows the events are independent. Otherwise, they are dependent. When I write "A n B", I mean "A intersect B". The intersect symbol looks similar to the lowercase letter n.
P(A)*P(B) = (3/4)*(2/5) = (3*2)/(4*5) = 6/20 = 3/10
Since that result is not the same as P(A n B) = 1/3, this means that the events are not independent. They are dependent events. The answer is choice D
