Answer:
9/25
Step-by-step explanation:
I guess you mean 45/125
they are divisible by 5
45/5 = 9
125/5 =25
9/25
Answer:
Step-by-step explanation:
Options B and D are correct as they are equal to 1728
22^7 - 22^4 = 2,494,123,632 .
Given two points; A(x₁,y₁) and B(x₂,y₂), the slope "m" is:
m=(y₂-y₁)/(x₂-x₁) or m=(y₁-y₂)/(x₁-x₂)
Therefore:
(-9,5)
(-7,10)
m=(10-5) / (-7-(-9))=5/(-7+9)=5/2
Answer: D. 5/2
Answer:
Step-by-step explanation:
a) P(K) = 0.7
b) P(R|K) = 1
c) P(K|R) = P(KnR) /P(R)
= P(K) x P(R|K) / ( P(K) x P(R|K) + P(K') P(R|K')
= 0.7 x 1 / ( 0.7 x 1 + (1-0.7) x 1/N)
= 0.7/(0.7 + 0.3/N)
d) P(K|R) > 0.99
0.7/(0.7 + 0.3/N) > 0.99
N > 42.86
N = 43 will be the value of N that will ensure that P(K|R) >99%
