Options:

A.) decrease because the same five numbers are not likely to occur again so soon.

B.) Increase because those five numbers must be lucky.

C.) be unaffected because every set of five numbers is equally likely on every attempt.

D.) be unknown because it depends on how many times those five numbers have won in the last several drawings.

Answer:

be unaffected because every set of five numbers is equally likely on every attempt.

Step-by-step explanation:

Number selection in the lottery is randomized with each set of number having equal chances of being selected. This means that each and every selection attempt is independent and the outcome of each attempt does not depend on any prior outcome or event. This means that if the numbers drawn from the most previous prior drawing are selected on the next attempt, the probability of winning on the next attempt Neither increases nor decreases. Hence , the probability of winning on the next attempt with this selection is unaffected.

A recipe calls for 3 cups of flour to make 2 batches of dinner rolls. One batch makes 15 rolls. Laura is making dinner for 12 pe
Maru [420]

Answer:

A

Step-by-step explanation:

3 cups of flour produces 2 batches of dinner rolls. So, if one batch makes 15 rolls, then 2 batches makes 30 rolls. Therefore, 3 cups of flour produces 30 rolls.

Laura wants to find how much flour she needs to make 12 rolls.

Here's the setup:

Let x be the number of cups of flour needed. Then,

(3 cups of flour)/(30 rolls)=(x cups of flour)/(12 rolls)

This is the set up for all equations involving ratios. The units should be consistent. Notice how I have flour/rolls=flour/rolls.

It is not necessary to solve the equation, but you should to make sure your answer makes sense. By cross-multiplying, we get x=(3*12)/30 or 1.2 cups.

This solution makes sense. Because 3 cups of flour produces 30 rolls, one cup produces 10 rolls. We need slightly more than 1 cup to get 12 rolls.

They give you the y-value in an (x, y) ordered pair. So you plug in 8 where the y is and solve. 

- 4x - 8 = 24

Add 8 to each side

- 4x = 32

Divide each side by - 4

x = - 8

So your ordered pair is (- 8, 8).
