A pair of dice was rolled many times and the results appear below. Based upon these result what is the experimental probability of rolling a 7
Outcome 2,3,4,5,6,7,8,9,10,11,12
Frequency 3,6,8,11,14,16,15,12,9,5,1

Answers

The experimental probability of rolling a 7 would be 4/25 (16%). Experimental probably is found by putting the frequency of the event over the total number of trials. In this case that is 16/100, which reduces to 4/25.

An urn contains 5 red marbles 9 white and 7 blue marbles marbles.A child randomly selects three (without replacement) from the urn.Round to four decimal place.Find the probability all marbles are the same.

Answers

Answer:

0.0970

Step-by-step explanation:

Red marbles, R= 5

White, W = 9

Blue, B = 7

Total = (5 + 9 + 7) = 21

Selecting 3 marbles without replacement :

Probability that all marbles are the same

P(RRR) or P(BBB) or P(WWW)

(5/21 * 4/20 * 3/19) + (7/21 * 6/20 * 5/19) + (9/21 * 8/20 * 7/19)

0.0075187 + 0.0263157 + 0.0631578

= 0.0969922

= 0.0970

What is the solution for the equation, 2(4x – 6) = 8x – 12

Answers

Simplifying

2(4x + -6) = 8x + -12

Reorder the terms:

2(-6 + 4x) = 8x + -12

(-6 * 2 + 4x * 2) = 8x + -12

(-12 + 8x) = 8x + -12

Reorder the terms:

-12 + 8x = -12 + 8x

Add '12' to each side of the equation.

-12 + 12 + 8x = -12 + 12 + 8x

Combine like terms: -12 + 12 = 0

0 + 8x = -12 + 12 + 8x

8x = -12 + 12 + 8x

Combine like terms: -12 + 12 = 0

8x = 0 + 8x

8x = 8x

Add '-8x' to each side of the equation.

8x + -8x = 8x + -8x

Combine like terms: 8x + -8x = 0

0 = 8x + -8x

Combine like terms: 8x + -8x = 0

0 = 0

Solving

0 = 0

Answer:

X = 1

Step-by-step explanation:

2(4x - 6) = 8x - 12

(8x - 12) = 8x - 12

    + 12          + 12

8x         =   8x

x         =        1

Brooke bought 5 plates for $44. If the price of the plates is always the same, which represents the total cost, y, of buying any number of plates, x?

Answers

Answer:

y = 8.80x

Step-by-step explanation:

Th price of one plate = $44 / 5 = $8.80

the cost of any x plate can be determined by multiplying $8.80 by x

y = $8.80x

For example if x is 10, y =  $8.80(10) = $88

If x = 100, y = $8.80(100) = $880

Answer:

y = 8.80x

Step-by-step explanation:

Th price of one plate = $44 / 5 = $8.80

the cost of any x plate can be determined by multiplying $8.80 by x

y = $8.80x

For example if x is 10, y =  $8.80(10) = $88

If x = 100, y = $8.80(100) = $880

5)114+X+37+X=139

2x+151. -151=139-151

X=-6

Answer:

1. x=11

2. x=39

3. x= 12

4. x=6

5. x=-6

Step-by-step explanation:

1. x+4= 10+2x-17

FG=GH

x+4=2x-7

11=x

2. 11x+71=12x+32

subtract from both sides

39=x

3. All angles of a triangle add to 180.

39+57+(8x-12)=180

96+(8x-12)=180

8x-12=84

8x=72

divide both sides by 8

x=9

4. Vertical angles are equal

68=11x+2

66=11x

divide

6=x

5. (114+x)+(37+x)=139

Add like terms

151+2x=139

subtract

2x=-12

x=-6

Step-by-step explanation:

True/ false questions = 5 ; number of options = 2 (True or false)

Ways of answering = 2^5 = (2 * 2 * 2 * 2 * 2) = 32

Number of Multiple choice questions = 5

Number of options (A - D) = 4 options

Ways of answering = 4^5 = (4 * 4 * 4 * 4 * 4) = 1024

Answers

Answer:

Step-by-step explanation:

basically, you have to look at the inequality. it is the same all around. so if the inequality has less than or equal too, or greater than or equal too, you need to have a thick solid line representing your function. if it is just less than or greater than, use a dotted line. to determine whether the shading goes above or below, you look at the in equality. greater than is above, and less than is below
