PLATOA six-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. In the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times.

The experimental probability of rolling a 3 is %, which is approximately % more than its theoretical probability. (Round off your answers to the nearest integer.)

Answers

Answer 1

Answer:

Answer:

The experimental probability of rolling a 3 is 30%, which is approximately 13% more than its theoretical probability.

Answer 2

Answer:

Answer:

StepLet's right out the amount of times out of 20 the number 3 came out for all trials:

6/20 , 6/20, 5/20, 7/20

This probability averages at: 6/20 (6 + 6 + 5 + 7 /4 ) = 0.3

The normal probability to get one number is = 0.1666 recurring (1/6)

In relation to the normal probability the probability of getting a 3 on this die is almost double.

The experimental probability consistent with this simulation is: 6/20 (0.3)

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The inequality will like this....

$x\geq53$

because if it says at least 53 people buy food from the food truck that means it could be 53 people or more.

Now for the graph it will be the one with the closed circle and the arrow pointing to the right.

The line is supposed to resemble how many people buy food from the food truck.

So the meaning of the closed circle is that the 53 is included within the possiblities and the arrow would show how much could be there since it said at least 53 people so there could be more.

Answer:

The answer will the closed circle with an arrow to the right on the 53

Explanation:

The closed circle with the arrow pointing left means equal to or greater than blank

It is at least 53 people, meaning it could be 53, 54, 55, or more forever

Christine has 28 jazz songs and classical songs on a playlist. The play list has 3 times as many jazz songs as classical songs. She has 7 times as many rock songs as classical songs. How many Jazz songs are in the playlist? How many rock songs are on the playlist?

Answers

I assume you mean the total number of jazz and classical songs combined is 28 songs?
3 times as many jazz as classical:
Means there is a ratio of 3 jazz to 1 classical, which means there are essentially 4 parts (3+1=4). So if we divide 28/4=7. This gives one part = number of classical songs, jazz is 3 parts so 7*3=21 jazz songs.
7 times as many rock as classical:
From above we know there are 7 classical songs. 7*7=49 rock songs.
Jazz=21 songs
Rock=49 songs

In January 2012, the U.S. Population was about 313 million people. In January 2017, it was about 324 million. What was the average rate of population change per year?

Answers

The average rate of population change per year will be 2.2 million.

The difference in population will be:

= 324 million - 313 million.

= 11 million

The difference in years will be:

= 2017 - 2012

= 5 years.

The average rate of population change per year will be:

= 11 million / 5

= 2.2 million

Answer: 2.2 million.

Step-by-step explanation:

To get the answer, you would need to make 324 million and 2017 a fraction(324 million as numerator (top), 2017 as denominator (bottom) and the same for 313 million and 2012) . From there, you subtract both fractions. You will get 11/5, which would equal 2 1/5. Multiply the 2 1/5 by 2 to get 2 20/100.
