Answer:
r < -12
Step-by-step explanation:
r / -6 +5 < 7
r / -6 < 7 - 5
r < -6(2)
r < - 12
-5 x b =-35
I’ve done this in school before my teacher told us that was the answer so
Answer:
Step-by-step explanation:
hello :
f(n)=f(n-1)+2
means : f(n)-f(n-1)=2
this is the arithmetic seq when the common dif is d= 2 and the first term is : 9
the n-ieme term is : f(n) = f(1) +(n-1)d
f(n) =9+2(n-1)
f(n) = 2n+7
so : f(5) = 2(5)+7 = 17
Answer:
0.001145
Step-by-step explanation:
Given that you are certain to get 3 jacks when selecting 51 cards from a shuffled deck.
When we draw 3 cards from 51 cards, we keep one card aside
The card can be either Jack or non Jack
Prob (the left over card to be Jack) = P(A) =
Prob (the left over card to be non jack ) = P(B) =
A and B are mutually exclusive and exhaustive
Let drawing 3 Jacks be the event C
P(C) = P(AC)+P(BC)
P(BC) = P(B)*P(C/B)\\
= \frac{28}{52} (4/51C3)\\
=1.034(10^{-4}
Adding we get
P(C)
