Two cards are drawn at random from an ordinary deck of 53 cards determine if the probability that both cards are diamonds if the first card is replaced before the second Drawn is

Answers

Answer 1
There are only 52 cards in a deck to begin with so not 53. There are 13 of each card. Meaning a 1 in 4 shot the first time and then 1 in 4 for you second try. Multiple you denominators and you get 4x4 = 16. You have a one in 16 chance of 2 diamond cards in a row or 6.25% chance

Area is length X width. So 16.25x 11.75= 190.9375 ft squared. Divide this by 20ft squared since that is how much is in a bag. And you get 9.54 which is abt 10 so that is your answer

Answer:

10

Step-by-step explanation:

Since we are dealing with area, we need to multiply 16 1/4 by 11 3/4.

If we do that, we get 190 15/16

So, if we divide 190 15/16 by 20:

[tex]190 \frac{15}{16} / 20 = 9.5[/tex]

You cannot have half a bag however. You will need to round the number to 10.

Angles around a point




Answers

Answer:

205°

Step-by-step explanation:

The total circle is 360°. The right angle is 90°, and you know the other angle is 64°. 90° + 64° is 154°. 360° -154° is 205°.

Answer:

We know that the angle around any given point is 360°

Therefore, according to the given problem,

[tex]x° + 64° + 90° = 360° \\ x° + 154° = 360° \\ x° = 360° - 154° \\ \boxed{x° = 206°}[/tex]

Hence, the value of x° is 206°

x° = 206° is the right answer.

A dose of 2g of medication has been ordered for patient.The medication comes in 4g/0.4ml.What volume will you give the patient?

Answers

Your answer is 0.2ml

To give the patient a dose of 2g medication with a strength of 4g/0.4ml, you should administer 50 ml of the medication.

Given that,

Dose ordered: 2g of medication

Medication strength: 4g/0.4ml

Conversion factor: 10

To calculate the volume of medication you need to give the patient,

Use a simple formula:

Volume (in ml) = (Dose ordered / Strength) x Conversion factor

In this case,

The dose ordered is 2g and the strength is 4g/0.4ml.

To find the conversion factor,

Divide 4g by 0.4ml, which equals 10.

So, using the formula,

The volume of medication you need to give the patient would be:

Volume (in ml) = (2g / 0.4ml) x 10

Now, calculating this:

Volume (in ml) = 5 x 10

Hence, you should give the patient 50ml of medication.

Jeremy needs 1/2 cup of milk for 2/3 cup of oats how many cups of milk is needed for each cup of oats

Answers

Using the principle of proportional relationship, the number of milk cups required per cup of oat is 0.75 cups

Setting up a proportional relationship between milk and oat :

1/2 cups = 2/3 cups

x cups = 1 cup

Cross multiply :

(2/3)x = 1/2

0.666666x = 0.5

Divide both sides by 0.66666 to isolate x

x = 0.5 / 0.666666

x = 0.75

Therefore, 0.75 cups of milk is required per cup of oat.

A real estate office pays its salespeople a weekly retainer of $220 plus commission of 2.5% for the first
$200 000 of the value of each property sold and 2% of each amount after that. Calculate the commission
received if the following houses are sold.

Answers

7- The commission for the sale of a $ 540,000 house was $ 12,020.

8- The commission for the sale of a $ 795,600 house was $ 17,132.

9- The commission during the 4 weeks of February was $ 24,690.

10- The commission during the 4 weeks was $ 27,754.

11- The house was worth $ 440,000.

Given that a real estate office pays its salespeople a weekly retainer of $ 220 plus commission of 2.5% for the first $ 200,000 of the value of each property sold and 2% of each amount after that, to determine the commission received if the following houses are sold, the following calculations must be performed:

7- a $ 540,000 house 540,000 - 200,000 = 340,000 220 + (200,000 x 0.025) + (340,000 x 0.02) = X 220 + 5000 + 6800 = X 12020 = X

8- a $ 795,600 house 795,600 - 200,000 = 595,600 220 + 5000 + (595,600 x 0.02) = X 5220 + 11912 = X 17132 = X

9- a $ 472,500 house and a $ 618,000 house 472,500 - 200,000 = 272,500 618,000 - 200,000 = 418,000 220 x 4 + 5000 + (272,500 x 0.02) + 5000 + (418,000 x 0.02) = X 880 + 10,000 + 5,450 + 8,360 = X 24,690 = X

10- a $ 384,000 unit, a $ 216,000 unit and a $ 593,700 house 384,000 - 200,000 = 184,000 216,000 - 200,000 = 16,000 593,700 - 200,000 = 393,700 880 + 5000 x 3 + (184,000 x 0.02) + (16,000 x 0.02) + (393,700 x 0.02) = X 15880 + 3680 + 320 + 7874 = X 27.754 = X

11- the value of a house whose commission is $ 9800 200,000 x 0.025 = 5000 9800 - 5000 = 4800 2 = 4800 100 = X 100 x 4800/2 = X 240,000 = X 240,000 + 200,000 = 440,000

How do you transpose a number

Answers

Answer:

Transposing a number is a type of error where two digits swap position in the sequence. An example would be to enter 13 instead of the desired 31. It could also be the error of dropping a needed zero as in writing 15 instead of the desired 150.

Step-by-step explanation:

Unless by "number" you mean musical score. Then transposing is rewriting the score in a new key.

Step-by-step explanation:

P = 90° , T = 36° ( given )

so,

90 + 36 + S = 180

126 + S = 180

S = 180 - 126 = 54°

S = 54°

therefore, S is 54° so, option D is correct.
