Which events are independent? Select three options.

Roll a number cube, and then roll the same number cube again.
Flip a coin, and then flip the coin a second time.
Remove a card from a deck, and then remove a second card.
Draw a card from a deck, replace it, and then draw a second card.
Take a marble out of a bag, and then take a second marble out of the bag.

Answers

Answer 1

Answer: The first, second, and fourth.

Step-by-step explanation:

1). When you roll a cube twice, the number you get on the first roll doesn’t impact the second. As a result, it’s independent.

2). When you flip a coin twice, what you get on the first flip doesn’t impact what you get on the second. As a result, it’s independent.

3). When you remove a card from a deck, then remove a second one WITHOUT replacing the first, the first card impacts the second draw. For example, when I draw the first card, my chances of drawing a two are 1/13. If I draw a two the first time, my chances of drawing a two the second time are 1/17 (3/51. The total is fifty-one since one card is missing). Since the first draw impacted the probability of the second, the events are NOT independent.

4). When you remove a card, replace it, then draw again, your chances of drawing the same card doesn’t change. For example, my odds of drawing a three are 1/13 (or 4/52). If I draw a three the first time, then put it back and draw again, my odds are still 1/13 because I put the card back in the deck. As a result, the event is independent.

5). If I take a marble from a bag, and then take a second marble, the first draw impacts the second. For example, if a bag has three blue marbles and three green marbles, my chances of getting a blue marble the first time are 1/2 (or 3/6). If I get a blue marble and choose again, WITHOUT replacing it, my chances of choosing another blue marble are 2/5 (since one marble is missing). Since the first draw impacting the probability of the second, the events are NOT independent.

Eva's new bunny weighted 1 7/8 pounds when she first got him 4 weeks ago. Now he weighs 2 1/4 pounds. How much weight has Eva's dog actually gained

Answers

Answer: Eva's dog actually gained 3/8 pounds0.375pounds)

Step-by-step explanation:

Step 1

Given that

old weight = 1 7/8  pounds

New weight = 2 1/4 pounds

weight gained = New weight - Old weight

Step 2

 weight gained = New weight - Old weight

                  2 1/4  pounds - 1 7/8 pounds

      2.25 pounds - 1.875 pounds

         0.375pounds = 3/8 pounds

There are 272 people in an audience. The ratio of adults to children is 5 : 3. How many are children? (please answer)

Answers

Answer:

There are 102 children

Step-by-step explanation:

Let us solve the question

∵ There are 272 people in an audience

∴ The total number of people = 272

∵ The ratio of adults to children is 5: 3

→ Find the sum of the two parts of the ratio

∴ The sum of the parts of the ratio = 5 + 3 = 8

→ By using the ratio method

→  Adults:  Children:  People

→  5        :   3            :  8

→  A        :   C           :  272

→ By using the cross multiplication

C × 8 = 3 × 272

∴ 8C = 816

→ Divide both sides by 8

C = 102

∵ C represents the number of children

There are 102 children

The length of a garden box is 6 feet longer than 4times the width. If the length of the garden box is 22 feet, what is the width of the garden box?
Wil name Branilest

Answers

Answer:

Width of the garden box = 4 feet

Step-by-step explanation:

Given that:

Length of garden box = 22 feet

Let,

w be the width of garden box

It is also given that:

The length of a garden box is 6 feet longer than 4 times the width.

L = 4w + 6

Putting L = 22

22 = 4w + 6

22 - 6 = 4w

4w = 16

Dividing both sides by 4

[tex]\frac{4w}{4}=\frac{16}{4}\\w=4[/tex]

Hence,

Width of the garden box = 4 feet

Is (2, 10) a solution to this system of equations?
y = 4x + 2
y = x + 8

Answers

Answer:

Yes, (2, 10) is a solution to this system:

y = 4x + 2

y = x + 8

Step-by-step explanation:

When graphed, the two equations cross at (2,10) making it a solution.

Answer:

Yes

Step-by-step explanation:

If y=4x+2 and y=x+8, then 4x+2=x+8

4x+2=x+8

4x=x+6

3x=6

x=2

Plugging this into the original equation "y=x+8", we obtain the result that y=10.

This means, (2, 10) is a solution  to the system.

Jamal has $15.00 to spend at the concession stand. He buys nachos for $7.50, and he wants to purchase some Sour Straws for $1.50 each. How many Sour Straws can Jamal purchase with the money that he has? Variable: ______________________________ Inequality: ______________________________ Solution: ______________________________

Answers

Answer: Variable: y= Number of sour straws.

Inequality: 7.50+1.50y ≤ 15

Solution: y ≤ 5

Step-by-step explanation:

Let  y= Number of sour straws.

Cost for nachos = $7.50

Cost per sour straw = $1.50

Total cost = 7.50+1.50y

Money he has $15

Total cost must be less than orequal to the money he has.

So required inequality: 7.50+1.50y ≤ 15

Subtract 7.50 from both sides

[tex]1.5y\leq 7.5\\\\\Rightarrow\ y\leq\dfrac{7.5}{1.5}\\\\\Rightarrow\ y\leq 5[/tex]

He can buy at most 5 sour straws.

Step-by-step explanation:

y = -6x

(12; -2)

-2 = -6 · 12

-2 = -72 - no

-9 = -6 · 3

-9 = -18 - no

(-10; 60)

60 = -6 · (-10)

60 = 60 -  yes

(18; -3)
