There are 52 cards in a standard deck: 13 hearts, 13 clubs, 13 diamonds , and 13 spades. Timothy draws four cards at random from

siniylev [52]

Answer:

$\dfrac{1}{4}$

Step-by-step explanation:

Total number of cards in a standard deck = 52

Number of hearts in the deck = 13

Number of clubs in the deck = 13

Number of diamonds in the deck = 13

Number of spades in the deck = 13

Four cards are drawn at random by Timothy.

These four cards are drawn from each one of the suits.

And the cards are not replaced.

Therefore, now cards remaining in each suit:

Remaining number of hearts in the deck = 12

Remaining number of clubs in the deck = 12

Remaining number of diamonds in the deck = 12

Remaining number of spades in the deck = 12

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

Here, number of favorable cases are 12 (i.e. number of hearts)

Total number of cases = 12 $\times$ 4 = 48

Therefore, the required probability is:

$\dfrac{12}{48} = \bold{\dfrac{1}4}$

Paula has her own business making cakes for

djverab [1.8K]

Answer:

Since Paula has her own business of making cakes for special occasions, and the total price (P) of one of Paula's cakes is represented by the equation P = 0.75S +10, where S is the number of people the cake serves, for determine what does the 0.75 represent in this situation and what does the 10 represent in this equation, the following mathematical reasoning must be carried out:

P is the price of the cake

S is the number of servings

Therefore, 0.75 is the value of each serving, which can be variable (the number of servings can vary)

In turn, 10 is the fixed cost of each cake.

It takes printer A 4 more minutes than printer B to print 40 pages. If working together, the two printers can print 50 pages in

Anastaziya [24]

Answer:

It will take printer A 24 minutes to print 80 pages.

Step-by-step explanation:

It takes printer A 4 more minutes than printer B to print 40 pages.

Let the time it takes printer B be x minutes, since printer A prints at 4 minutes more, it prints at (x + 4) minutes.

Printer A prints at the rate of (40/(x+4)) pages per minute.

Printer B prints at the rate of (40/x) pages per minute.

If working together, the two printers can print 50 pages in 6 minutes

They can print at the rate of 50 pages per 6 minutes, if working together.

Let us add these ratios, the

40/(x + 4) + 40/x = 50/6

Divide by 40

1/(x + 4) + 1/x = 5/24

(x + x + 4)/x(x + 4) = 5/24

2x + 4 = (5/24)(x² + 4x)

48x + 96 = 5x² + 20x

5x² - 28x - 96 = 0

Solving this using the quadratic formula,

x = [-b ± √(b² - 4ac)]/2a

a = 5, b = -28, and c = -96

x = [28 ± √(784 + 1920)]/10

= 28/10 ± √(2704)/10

= 28/10 ± 52/10

x = (28+52)/10 = 80/10 = 8

x = (28 - 52)/10 = -24/10 = -2.4

So, x is either 8 or -2.4

Since we are dealing with time, the realistic value is the positive value, x = 8, then we choose x = 8 minutes.

It takes printer A (x + 4) minutes to print 40 pages.

x + 4 = 12 minutes.

So, it takes it 12 minutes to print 40 pages.

Easily, it will take it twice as much time to print 80 pages.

So, it will take it 24 minutes to print 80 pages.

Tyrell Otis deposited his IRS refund check for $760 at 5% and made no other deposits or withdrawals. How much simple interest di

Helga [31]

Answer:

He earned $114 in interest.

The final amount in the account is $874

Step-by-step explanation:

Initial balance (b): $760

Interest rate (i): 0.05

Period (n): 3 months

Simple interest applications yield the same amount in interest every period. Therefore, the total simple interest earned can be defined by:

$I = n*B*i\\I= 3*760*0.05\\I=114$

The final amount (A) in the account is the initial balance plus the interest earned in 3 months.

$A = 760 +114\\A=874$

He earned $114 in interest and the final amount in the account is $874
