Answer:

Cricket match toss and playing cards

Step-by-step explanation:

Example 1: Cricket match toss

There are two teams in a cricket match. Each team's captain comes forward for the toss. There are 2 sides of the coin; head an tail. Each captain has an equal chance of either getting a head or a tail.

Total number = 2

Chances of head/tail = 1

Therefore the probability for each captain of either getting a head or a tail is 1/2.

Example 2: Playing cards

A deck of cards has 52 cards. There are total 26 black cards and 26 red cards out of which there are 13 clubs, 13 spades, 13 hearts and 13 diamonds. Each category has a King, Queen, Jack, Ace, 2, 3, 4, 5, 6, 7, 8, 9 and 10 card.

Total number of cards: 52

Total number of 10 of spades: 1

The probability of getting a 10 of spades will be 1/52.

V + 9 ---------- = 8 3 Can someone help me ??

bagirrra123 [75]

$\frac{v + 9}{3} = 8$

Multiply both sides by 3, because 3 is our denominator (bottom number in a fraction), and we want to get rid of the denominator.

3 × (v + 9) = 8 × 3

Simplify.

3v + 27 = 24

Then, subtract both sides by 27.

3v = 24 - 27

Simplify.

3v = -3

Divide both sides by 3.

v = -1

Lauren is making muffins. Her muffin recipe calls for 3 1 −4 cups of flour. She has 10 1 −2 cups of flour. A. Explain a method f

Soloha48 [4]

Answer:

A. 3.2307692308 batches of Muffins

B. 16 1/4 cups of flour

Step-by-step explanation:

Lauren is making muffins. Her muffin recipe calls for 3 1 −4 cups of flour. She has 10 1 −2 cups of flour.

A. Explain a method for determining the number of batches of the muffin recipe Lauren can make. Then use your method to find the number of batches she can make.

Her muffin recipe calls for 3 1 −4 cups of flour. She has 10 1 −2 cups of flour.

3 1/4 cups of flour = 1 batch of Muffin recipe

10 1/2 cups of flour = x

3 1/4 × x = 10 1/2 × 1

x = 10 1/2 ÷ 3 1/4

x = 21/2 ÷ 13/4

x = 21/2 × 4/13

x = 42/13

x = 3.2307692308 batches of Muffins

B. If Lauren plans to make 5 batches of the muffin recipe, use what you know about operating with rational numbers to predict the amount of flour she needs. Justify your prediction.

3 1/4 cups of flour = 1 batch of Muffin recipe

Hence,

1 batch = 3 1/4 cups of flour

5 batches = x

Cross Multiply

x = 5 × 3 1/4 cups of flour

x = 5 × 13/4

x = 65/4

x = 16 1/4 cups of flour
