As the distance increases, the gravitational forces between the two objects decreases. It is an inverse relationship. This means the statement is true.

Steve seems to be ignoring that you might pick 4 socks of the same color in a row.

Math
First the choice of one color = 4/8. With the 7 remaining socks, the choice of the other color = 4/7. With 3 remaining of each color in the 6 socks left, P = 3/6. If the events are independent, the probability of both/all events occurring is determined by multiplying the proba...

From your set of numbers, there is no mode or modal class. If the scores were grouped into intervals, one could be the modal class. The mean or median would be better to indicate average class sizes. Any of the measures of central tendency can be used, if the distribution is r...

Gravitational pull would pull it into the sun. The inertia of its orbit keeps this from happening

Math
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown. 81 * 38 = 3078, which is the product. For 81, 3 * 3 * 3 * 3 are factors. However, 81 and 38 are also factors of 3078.

From your data, with four tosses, you would get 3 tails and one head by chance. The probability of one head would then be 1/4. If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

This is the same as both are either red or green. red = (20-5-9)/20 green = 5/20 Either-or probabilities are found by adding the individual probabilities. This is for one choice. But you are looking fro two choices. If the events are independent, the probability of both/all ev...

2x - y = 4 Subtract 4 and add y to both sides of the above equation. y = 2x -4 8x - 4y = 16 Substitute 2x-4 for y in last equation and solve for x. Insert that value into the first equation and solve for y. Check by inserting both values into the second equation.
