Answer: The Smith family price for the meal is $36.39

Step-by-step explanation:

The Smith family went out to dinner. • The price of the meal was $29.85.

The sales tax was 6% of the price of the meal.

LEts find sales tax amount

sales tax amount = price of meal * sales tax 6%(0.06)

= 29.85 * 0.06 = 1.791

sales tax amount = 1.791

Price of the mean with sales tax = 29.85 + 1.791= 31.641

The tip was 15% of the meal and the sales tax

now we find out tip amount for 31.641

15 % is 15/ 100 = 0.15

Tip amount = 31.641 * 0.15 = 4.74615

Now we add the top amount with 31.641

31.641+ 4.74615=36.38715

the Smith family price for the meal = $36.39

g If there are 52 cards in a deck with four suits (hearts, clubs, diamonds, and spades), how many ways can you select 5 diamonds

dezoksy [38]

Answer:

The number of ways to select 5 diamonds and 3 clubs is 368,082.

Step-by-step explanation:

In a standard deck of 52 cards there are 4 suits each consisting of 13 cards.

Compute the probability of selecting 5 diamonds and 3 clubs as follows:

The number of ways of selecting 0 cards from 13 hearts is:

${13\choose 0}=\frac{13!}{0!\times(13-0)!} =\frac{13!}{13!}=1$

The number of ways of selecting 3 cards from 13 clubs is:

${13\choose 3}=\frac{13!}{3!\times(13-3)!} =\frac{13!}{13!\times10!}=286$

The number of ways of selecting 5 cards from 13 diamonds is:

${13\choose 5}=\frac{13!}{5!\times(13-5)!} =\frac{13!}{13!\times8!}=1287$

The number of ways of selecting 0 cards from 13 spades is:

${13\choose 0}=\frac{13!}{0!\times(13-0)!} =\frac{13!}{13!}=1$

Compute the number of ways to select 5 diamonds and 3 clubs as:

${13\choose0}\times{13\choose3}\times{13\choose5}\times{13\choose0} = 1\times286\times1287\times1=368082$

Thus, the number of ways to select 5 diamonds and 3 clubs is 368,082.
