Answer:
5 must be added to both the terms to get the ratio 4:5.
Step-by-step explanation:
(3+x)/(5+x)=4/5
Therefore,
15+5x=20+4x
=5x-4x=20-15
=x=5

Answer:
Choice D:
Step-by-step explanation:
If we check them one by one...
Choice A is all correct, so we leave that there for now
Choice B's 3x12 is equal to 36, so therefore it's wrong
Choice C has the same mistake as Choice B - 3x12 is not equal to 32
Choice D is all correct, so therefore it is the answer
Though Choice A is also correct, the question asked for <u>all</u> of the different ways you can arrange the cars
So, therefore... the answer is A!

Answer:
0.01923 or 1.92 %
Step-by-step explanation:
The probability of drawing a queen card out of deck is 4/52
∴ P(Q)= 4/52
there are 4 queens in a deck, one of each suit.
The probability of drawing a diamond card out of deck is 13/52
∴P(D)= 13/52
there are 13 cards in diamond suit (including the three face cards).
The total will remain 52 as he has replaced the first card and have not moved it aside
therefore, the net probability for both scenarios will be defined by calculating both probabilities.
P= P(Q) x P(D)
P= 4/52 x 13/52
P=1/52
P=0.01923 (converting into percentage)
P=0.01923 x 100%
P=1.92 %
Answer: the probability that James draws a queen card as the first card and a diamond card as the second card is 1.92%
