<h3>

**Answer: Choice C) 9/100**</h3>

=======================================================

Explanation:

We have these two events

- A = the coin lands on tails
- B = the number cube (aka dice) lands on '2'

The experimental (aka empirical) probabilities of each are

- P(A) = 36/80 = 9/20
- P(B) = 16/80 = 1/5

Note how P(A) is not 1/2 like we expect; however it's fairly close because 9/20 = 0.45 while 1/2 = 0.5 in slight contrast. The experimental probability never 100% lines up with the theoretical probability, but will get closer as you do more trials (due to the law of large numbers). A similar situation happens with P(B). The theoretical probability would be P(B) = 1/6 = 0.1667

Events A and B are independent, which allows us to multiply the probabilities:

P(A and B) = probability of getting tails and rolling a '2'

P(A and B) = P(A)*P(B)

P(A and B) = (9/20)*(1/5)

P(A and B) = (9*1)/(20*5)

P(A and B) = **9/100 which points the answer to choice C**

--------------

Slight alternative method:

P(A and B) = P(A)*P(B) = (36/80)*(16/80) = 0.09 = **9/100**

this method involves typing (36/80)*(16/80) into your calculator.

X can you please give me braknlistest yes yes thank yoy

**Answer:**

9,000

**Step-by-step explanation:**

9474

**Locate the thousands place:**

<u>**9**</u>474

**Check the number to the right:**

9<u>**4**</u>74

If the number is greater than or equal to 5, we round up. If the number is less than or equal to 4, we round down.

Since there is a '4', we round down.

**9474 ≈ 9000 **

Hope this helps.

**Answer:**

so both tables are proportional

1. in the green table

y divided by x =

1/5 for each row

2. in the blue table

y divided by x =

2/5 for each row

**Step-by-step explanation:**

**/ means divided by**

divide y by x

for both tables

in each table

if y divided by x

show the same number

for every row

then its proportional

1. in the green table

y divided by x =

1/5 for each row

2. in the blue table

y divided by x =

2/5 for each row

so both tables are proportional
