Erik is performing a marble experiment in math class. His teacher places an equal number of black, red, and white marbles in a bag. Then, Erik randomly takes out a marble, records the result, and puts the marble back in the bag. Each of the first four times Erik takes out a marble, he gets a black marble.

A. What is the theoretical probability of Erik picking a black marble next time? Based on Erik's results, what is the experimental probability of Erik picking a black marble next time?
B. Explain the difference between the two probabilities you found in part A.
C. What is the theoretical probability and likelihood of getting four black marbles in a row?

Children get a 15% discount on tickets to an amusement park. Jun had a coupon for 5% off any two tickets. He used the coupon for himself and his 4-year-old son, Jack. If regular admission for a ticket was $60, what did Jun pay for the two tickets?

A girl's feet are negative 2 over 4 yards from the surface of a pool. A boy's feet are negative 3 over 4 yards from the surface of the pool. Determine whose feet are closer to the surface.

The girl's feet are closer to the surface of the pool because negative 2 over 4 > negative 3 over 4.
The boy's feet are closer to the surface of the pool because negative 2 over 4 > negative 3 over 4.
The girl's feet are closer to the surface of the pool because negative 2 over 4 < negative 3 over 4.
The boy's feet are closer to the surface of the pool because negative 2 over 4 < negative 3 over 4.

Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)


Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000


Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.


Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12


Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.


(Answer 1, 2, 3, 4 and 5 )


1. A sample of gold contains 3,800,000,000,000,000,000 atoms. Express this number in scientific notation.


2. A sample of silver contains 400,000,000,000,000 atoms. Express this number in scientific notation.


3. A sample of carbon has a mass of 0.000000000000000000034 kg. Express this mass in scientific notation.


4. A sample of silicon contains 5.23 × 10^11 atoms. Write this amount as a whole number.
