Answer:

Step-by-step explanation:

Let's look at some other ratios that equal 8:6  We could increase them or decrease them.  For instance if we cut one in half we cut the other one in half, so 8:6 would be the same ratio as 4:3.  With the same thinking if we double one we double the other so 8:6 s the same ratio as  16:12.  Now, we want to go from 8 to 28.  What do we multiply 8 by to get to it?  Or, it might be easier to use 4:3 and see what you multiply 4 by.  Then you multiply 3 by that same number to get the other number.

Let me know if that doesn't make sense.

Answer:

Step-by-step explanation:

given that a deck of cards is shuffled.

we know in a deck there are 52 cards, 13 cards of each variety spade, clubs hearts and dice.  Red are 26 and black are 26.  kings, will be 4.

(a) the top card is the king of spades and the bottom card is the queen of spades?

(iii) 1/52 × 1/52

Top has 1/52 and bottom has 1/52 and these are independent.

(b) the top card is the king of spades and the bottom card is the king of spades?

(viii) None of the above

Because it is impossible.

(c) the top card is the king of spades or the bottom card is the king of spades?

(iv) 1/52 + 1/52

This is the sum of probabilities because there is no common event for these two.

(d) the top card is the king of spades or the bottom card is the queen of spades?

(ii) 1/52 + 1/51 (once king of spades is there, then probability is 1/51 for bottom card)

(e) of the top and bottom cards, one is the king of spades and the other is the queen of spades?

(vii) 2/52 × 1/51

Because this is twice of probability d.

The percent discount is 30%.
If you multiply $32 by .30, you will get $9.60. That is the amount of the discount. If you subtract $9.60 from $32, you will get $22.40 which is what he paid before tax. Therefore the percent discount is 30%.
