I think I might be right but you do 6x6 which would be 36.
Because it is being increased by 2.3 every time.
Answer:
m=16
Step-by-step explanation:
(6+6)/m=6/8
12/m=6/8
M=16
Answer:
(1) 60
(2) 487635
Step-by-step explanation:
(1) Distinguishable shuffles means that all the cards must be different from each other. We have 9 different cards types having 4 cards each and 1 card having 24 copies of it. So, in a distinguishable shuffle, we can get 1 card each from the 9 different cards (C1 - C9) and another card from the set of 24 identical cards. So we will have a total of 10 cards.
The possible ways of getting these cards are:
9 x (⁴C₁) + ²⁴C₁
(9 x 4) + 24 = 60
There are 60 distinguishable shuffles.
(2) Here we are simply asked to calculate the number of 4-card combinations that can be drawn from the deck of 60 cards. It is not mentioned that the cards must be distinguishable so,
Possible hands of four cards = ⁶⁰C₄ = 487635
Answer:
$2400
Step-by-step explanation:
Let x represent the amount invested at 9%. (3600-x) will be the amount invested at 8%. The total interest earned is then ...
312 = 0.09x +0.08(3600 -x)
24 = .01x . . . . subtract 288, simplify
2400 = x . . . . divide by .01
$2400 was invested in the 9% account.
