Many games involve chance and they usually involved either dice or cards. For this activity, we will look at a common game called 7‐11 where two dice are rolled. If the roll adds up to 7 or 11, the player wins. If the roll adds up to 2, 3, or 12, the player loses. If there is any other sum, it is a draw (no winner or loser). Use this two‐dice roll scenario to complete the problems below.

1. Create a tree diagram to determine all the possible outcomes of rolling two dice.

Answers

I’m going to categorize them of how you win or lose.

Win: 3 +4, 6+1, 2+5, 5+6

Answers

Answer:

1/4⋅(-12) = -3

(-1/3)⋅39 = -13

(-2/5)⋅(-34) = 13.6

8/3⋅(-42) = -112

Step-by-step explanation:

just please use a calculator

1/4*(-12)=-3
(-1/3)*39=-13
(-4/5)*(-75)=+60
(-2/5)*(-34)=68/5=13 3/5=13.6

Now we have to,

→ Find the equivalent expression.

The property we use,

→ Distributive property.

The expression is,

→ 8(a + 4)

Let's simplify the expression,

→ 8(a + 4)

→ 8(a) + 8(4)

→ (8 × a) + (8 × 4)

→ 8a + 32

Hence, the answer is 8a + 32.

Answer:

95%

Step-by-step explanation:

So, we can see on the chart that 78 out of 82 people from ages 18 to 22 use Face.book. So we're trying to find what percentage 78 is of 82:

The first step is to write 78 as a fraction of 82, which is:

78/82

In order to find the simplest form of 78/82 we cancel out the greatest common divisor of 78 and 82, which is 2 :

78/82 = 37/41  

Now we just need to convert this fraction to a percentage :

 37/41 = 95% (rounded)

So we have the final answer :

78 is 95% of 82

Which means that:

Approximately 95% of people from ages 18 to 22 use Face.book

hope this helps:)

Answers

Answer:

I believe that the answer is 21x+14 and 7(3x+2).

Step-by-step explanation:

I hope this helps, have a blessed day.

Answer:

A. 21x + 14 and 7(3x + 2).

Step-by-step explanation:

23x - 14 + 2x = 21x + 14

25x - 14 ≠ 21x + 14

x + x + 5 = x² + 5

2x + 5 ≠ x² + 5

9x² + 9x + 5 ≠ 18x² + 5

21x + 14 = 7(3x + 2)

21x + 14 = 21x + 14.

Your answer is A, 21x + 14 and 7(3x + 2).

Answer:

the exact form for that is 41/42

Answer: 41/42

Step-by-step explanation:

1. You are given the mixed numbers 4 35/42 and 3 36/42. Multiply the whole number by the denominator and add it to the numerator. In this case, do 4*42, which gives us 168, which when added to 35, gives us 203/45. Doing this for 3 36/42 gives us 162/45, by multiplying 3 by 42, and then adding 36 to the result.

2. Subtract 203 - 162, which is 41. With a denominator of 42, this gives us 41/42.
