Answer:

Step-by-step explanation:

Two things to note;

1. Since there's only one 2 or hearts and one 3 of clubs

2. The first card is replaced after it's drawn

Probability of 2 of hearts = 1/52

Probability of 3 of clubs = 1/52

They both have the same probability of being drawn.

Kobotan [32]

Answer:

-2.9

Step-by-step explanation:

You are really subtracting. Note that if you have a positive & negative sign directly next to each other, you will subtract:

-1.2 + (-1.7) = -1.2 - 1.7 = -2.9

-2.9 is your answer.

Find P 20 of the following arithmetic sequence: 206, 212, 218, 224....
Yanka [14]

Answer:

p_{20} = 1.25528

P₀ = 206 and difference d = 6

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the arithmetic sequence

                 206,212,218,224,.....

P₀ = 206 and difference d = 212-206 = 6

The n^{th} term of the sequence

   t_{n} = ar^{n-1}

<u><em>Step(ii):-</em></u>

The n^{th} term of the sequence

   P_{n} = ar^{n-1}

Put n=20

P_{20} = 206 ( 6) ^{20-1}

p_{20} = 1.25528

Complete the following statements.
stiv31 [10]

Answer:

A soda bottle contains 2 liters of liquid. Therefore:

The soda bottle contains  67.62 fluid ounces of liquid.

The soda bottle contains 0.525  gallons of liquid.

2) A milk jug contains 2 gallons of milk. Therefore:

The milk jug contains 8  quarts of milk.

The milk jug contains 7.6 liters of milk.

Step-by-step explanation:

We need to complete the statements.

1)

A soda bottle contains 2 liters of liquid. Therefore:

The soda bottle contains -------  fluid ounces of liquid.

  • Converting Liters to fluid ounces

We know that 1 liter = 33.81 fluid ounces

So,  2 liter = 2 x 33.81 = 67.62 fluid ounces

The soda bottle contains 67.62  fluid ounces of liquid.

The soda bottle contains  gallons of liquid.

  • Converting liters to gallons

As, we are not given direct conversion from liters to gallons, first we convert liter to quarts and then convert quarts to gallons

We know that

1 liter = 1.05 quarts

2 liters = 2 x 1.05 = 2.1 quarts

4 quarts = 1 gallon

1 quarts = 1/4 gallon

2.1 quarts = 1/4 * 2.1 = 0.525 gallon

The soda bottle contains 0.525  gallons of liquid.

2)

A milk jug contains 2 gallons of milk. Therefore:

The milk jug contains -------- quarts of milk.

  • Converting gallons to quarts

We know:

1 gallon = 4 quarts

2 gallons = 2 x 4 = 8 quarts

The milk jug contains 8 quarts of milk.

The milk jug contains ------  liters of milk.

  • Converting gallons to liters

We know:

1 gallon = 4 quarts

2 gallon = 8 quarts

1.05 quarts = 1 liter

1 quarts = 1/1.05 liter

8 quarts = 1/1.05 * 8 = 7.6 liter

The milk jug contains 7.6 liters of milk.
