You randomly guess the answers to four true-false questions.

Which simulation can you use to model the answers?

A. Roll four number cubes. Let the number 1 represent a correct answer and the number 2 represent an incorrect answer.

B. Roll a number cube and let the numbers 1 through 4 represent the number of questions you guess correctly. Run 40 trials.

C. Roll two number cubes. Let one number cube represent a correct answer and the other number cube represent an incorrect answer. Run 40 trials.

D. Roll four number cubes. Let an odd number represent a correct answer and an even number represent an incorrect answer. Run 40 trials.

Use the simulation results to find the experimental probability that you answer all four questions correctly.

what is 2/3 of 16 (please and thank you)

Answers

Answer:

     _

10.6

hope dis helps ^-^

The requried value of 2/3 fraction  of 16 is 10 and 2/3, or approximately 10.67.

To find 2/3 of 16, you can multiply 16 by the fraction 2/3:

(2/3) * 16 = (2 * 16) / 3

Now, calculate the numerator:

2 * 16 = 32

So, the result is:

(2/3) * 16 = 32 / 3

Next, simplify the fraction:

(2/3) * 16 = 10 and 2/3 or 10.67 (rounded to two decimal places)

Therefore, 2/3 of 16 is 10 and 2/3, or approximately 10.67.

26 – x = 14. what is x

Answers

X=12

Dkdndiekodrn rjrjrnrirnr

Answer:

x=12

Step-by-step explanation:

start with this equation:

26-x=14

it's best to make the x variable positive at all times.

to do that, you need to make everything else positive.

-26+x=-14

then add 26 to both sides.

x=-14+26

which basically says 26-14...

x=12
