Answer:

1 \to 22 \to 0.176

2 \to 13 \to 0.104

3 \to 18 \to 0.144

4 \to 29 \to 0.232

5 \to 37 \to 0.296

6 \to 6 \to 0.048

Step-by-step explanation:

Given

n = 125

See attachment for proper table

Required

Complete the table

Experimental probability is calculated as:

Pr = \frac{Frequency}{n}

We use the above formula when the frequency is known.

For result of roll 2, 4 and 6

The frequencies are 13, 29 and 6, respectively

So, we have:

Pr(2) = \frac{13}{125} = 0.104

Pr(4) = \frac{29}{125} = 0.232

Pr(6) = \frac{6}{125} = 0.048

When the frequency is to be calculated, we use:

Pr = \frac{Frequency}{n}

Frequency = n * Pr

For result of roll 3 and 5

The probabilities are 0.144 and 0.296, respectively

So, we have:

Frequency(3) = 125 * 0.144 = 18

Frequency(5) = 125 * 0.296 = 37

For roll of 1 where the frequency and the probability are not known, we use:

Total \ Frequency = 125

So:

Frequency(1) added to others must equal 125

This gives:

Frequency(1) + 13 + 18 + 29 + 37 + 6 = 125

Frequency(1) + 103 = 125

Collect like terms

Frequency(1) =- 103 + 125

Frequency(1) =22

The probability is then calculated as:

Pr(1) = \frac{22}{125}

Pr(1) = 0.176

So, the complete table is:

1 \to 22 \to 0.176

2 \to 13 \to 0.104

3 \to 18 \to 0.144

4 \to 29 \to 0.232

5 \to 37 \to 0.296

6 \to 6 \to 0.048

A sample originally contains 21 grams of a radioactive isotope. After 45 days, 17.3 grams of the isotope remain in the sample.
Darya [45]

Answer:

The answer to your question is:  128 days

Step-by-step explanation:

Data

original mass = 21 g

after 45 days = 17.3 g

Process

mass transform = 21 - 17.3 = 3.7 g

               

                                21 g ----------------------- 100 %

                                3.7 g ---------------------   x

                                x = (3.7 x 100) / 21

                                x = 17.61 %

                               17.61 % -------------------  45 days

                               50%    --------------------  x

                              x = (50 x 45) / 17.61

                              x = 127.8 ≈ = 128 days

How do you read gas prices.??
iren2701 [21]
You usually get four prices for four different gasoline's you can pump.

ex.
unleaded =3.89
unleaded plus =3.99
unleaded premium =4.55
diesel #2= 4.65

so unleaded gas is $3.89 per gallon of gas.
so if you got 5 gallons of gas it would be 5 times$3.89
5 \times 3.89
these prices are just an example.
