The “greenhouse effect” is the process that occurs when the sun's heat becomes trapped in Earth's atmosphere. As explained in an article at the website of Smithsonian Magazine, the French mathematician Joseph Fourier is often credited as the first person to study this process. According to NASA, this process happens because the sun shines through the atmosphere during the day. It heats up Earth’s surface. At night, the surface cools, and the heat is released back into the air. However, some of the heat is trapped beneath a layer of carbon dioxide and other gases. The University Corporation for Atmospheric Research (UCAR) lists methane as one of the other gases that trap heat on Earth.

Calculate the mean of each data set.
Calculate the mean absolute deviation (MAD) of each data set.
Which set is more variable? How do you know?
To find the mean of each data set, we add up all the heights and divide by the total number of measurements.
For Soil A:
- The total number of measurements is 11+6=17.
- The sum of all the heights is (9 x 100) + (6 x 10) + (5 x 100) + (2 x 10) + (1 x 100) + (1 x 10) + (5 x 100) + (1 x 10) + (0 x 100) + (2 x 10) + (1 x 100) = 2140.
- The mean is 2140/17 = 125.88 cm.
For Soil B:
- The total number of measurements is 4+6+7=17.
- The sum of all the heights is (3 x 100) + (9 x 10) + (0 x 100) + (2 x 10) + (3 x 100) + (6 x 10) + (7 x 10) + (8 x 10) + (3 x 100) = 1960.
- The mean is 1960/17 = 115.29 cm.
To find the mean absolute deviation (MAD), we first need to find the absolute deviations from the mean. For each measurement, we subtract the mean from the measurement and take the absolute value of the difference. Then we find the mean of all these absolute deviations.
For Soil A:
- The absolute deviations from the mean are: 7.88, 9.88, 0.12, 4.88, 20.12, 24.12, 21.12, 8.88, 21.88, 4.12, 15.88.
- The sum of all these absolute deviations is 139.88.
- The mean absolute deviation is 139.88/17 = 8.23 cm.
For Soil B:
- The absolute deviations from the mean are: 2.71, 6.71, 15.29, 12.29, 14.71, 0.29, 6.71, 8.71, 5.29.
- The sum of all these absolute deviations is 72.32.
- The mean absolute deviation is 72.32/17 = 4.26 cm.
To compare the variability of the two data sets, we can compare their mean absolute deviations. The data set with the larger mean absolute deviation has more variability. In this case, Soil A has a mean absolute deviation of 8.23 cm, while Soil B has a mean absolute deviation of 4.26 cm. Therefore, Soil A is more variable than Soil B.
For Soil A:
- The total number of measurements is 11+6=17.

- The mean is 2140/17 = 125.88 cm.
For Soil B:
- The total number of measurements is 4+6+7=17.
- The sum of all the heights is (3 x 100) + (9 x 10) + (0 x 100) + (2 x 10) + (3 x 100) + (6 x 10) + (7 x 10) + (8 x 10) + (3 x 100) = 1960.

- The sum of all these absolute deviations is 139.88.
- The mean absolute deviation is 139.88/17 = 8.23 cm.
For Soil B:
- The absolute deviations from the mean are: 2.71, 6.71, 15.29, 12.29, 14.71, 0.29, 6.71, 8.71, 5.29.
- The sum of all these absolute deviations is 72.32.
- The mean absolute deviation is 72.32/17 = 4.26 cm.

In this case, Soil A has a mean absolute deviation of 8.23 cm, while Soil B has a mean absolute deviation of 4.26 cm. Therefore, Soil A is more variable than Soil B.

You have a bag with 20 marbles: 2 yellow, 5 green, 12 red, and 1 blue. Which of the following statements are true? Select all that apply.
A. The probability of choosing a yellow, green, red, or blue marble is 1.
B. The probability of choosing a yellow marble is less than the probability of choosing a blue marble.
C. The probability of choosing a green marble is 0.25.
D. The probability of choosing a black marble is zero.
A. The probability of choosing a yellow, green, red, or blue marble is 1.
B. The probability of choosing a yellow marble is less than the probability of choosing a blue marble.
C. The probability of choosing a green marble is 0.25.
D. The probability of choosing a black marble is zero.
The correct statements are:
A. The probability of choosing a yellow, green, red, or blue marble is 1. (True, because these are the only colors of marbles in the bag.)
D. The probability of choosing a black marble is zero. (True, because there are no black marbles in the bag.)
B. The probability of choosing a yellow marble is less than the probability of choosing a blue marble. (False, because the probability of choosing a yellow marble is 2/20 = 0.1, while the probability of choosing a blue marble is 1/20 = 0.05. Therefore, the probability of choosing a yellow marble is greater than the probability of choosing a blue marble.)
C. The probability of choosing a green marble is 0.25. (False, because the probability of choosing a green marble is 5/20 = 0.25, which is a fraction or ratio rather than a decimal probability.)
A. The probability of choosing a yellow, green, red, or blue marble is 1. (True, because these are the only colors of marbles in the bag.)
D. The probability of choosing a black marble is zero. (True, because there are no black marbles in the bag.)
B. The probability of choosing a yellow marble is less than the probability of choosing a blue marble. (False, because the probability of choosing a yellow marble is 2/20 = 0.1, while the probability of choosing a blue marble is 1/20 = 0.05. Therefore, the probability of choosing a yellow marble is greater than the probability of choosing a blue marble.)
C. The probability of choosing a green marble is 0.25. (False, because the probability of choosing a green marble is 5/20 = 0.25, which is a fraction or ratio rather than a decimal probability.)
Which event has a probability of 1?
A. flipping heads on a two-sided coin
B. rolling an even number on a six-sided number cube
C. choosing a red or blue marble out of a bag filled with red and blue marbles.
D. spinning blue on a spinner that has an equal number of red and yellow spaces.
A. flipping heads on a two-sided coin
B. rolling an even number on a six-sided number cube
C. choosing a red or blue marble out of a bag filled with red and blue marbles.
D. spinning blue on a spinner that has an equal number of red and yellow spaces.
The correct answer is C. choosing a red or blue marble out of a bag filled with red and blue marbles.
If a bag contains only red and blue marbles, then choosing a red or blue marble is certain. Therefore, the probability of choosing a red or blue marble is 1.
In contrast, flipping heads on a two-sided coin has a probability of 0.5, rolling an even number on a six-sided number cube has a probability of 0.5, and spinning blue on a spinner that has an equal number of red and yellow spaces has a probability of 1/3.

Which event is considered neither likely nor unlikely?
A. rolling a number greater than 1 on a six-sided number cube
B. rolling a 1 on a six-sided number cube
C. getting heads when flipping a coin
D. choosing an X, Y, or Z from a bag containing all the letters of the alphabet
A. rolling a number greater than 1 on a six-sided number cube
B. rolling a 1 on a six-sided number cube
C. getting heads when flipping a coin
D. choosing an X, Y, or Z from a bag containing all the letters of the alphabet
The correct answer is A. rolling a number greater than 1 on a six-sided number cube.
This event is considered neither likely nor unlikely because it has an equal chance of occurring and not occurring. On a six-sided number cube, there are three numbers greater than 1 (2, 3, 4) and three numbers that are not (1, 5, 6). Therefore, the probability of rolling a number greater than 1 is 3/6 or 1/2, which is not a high or low probability.
In contrast, rolling a 1 on a six-sided number cube is an unlikely event, getting heads when flipping a coin is a likely event (assuming a fair coin), and choosing an X, Y, or Z from a bag containing all the letters of the alphabet is neither likely nor unlikely (assuming all letters have an equal chance of being chosen).
This event is considered neither likely nor unlikely because it has an equal chance of occurring and not occurring. On a six-sided number cube, there are three numbers greater than 1 (2, 3, 4) and three numbers that are not (1, 5, 6). Therefore, the probability of rolling a number greater than 1 is 3/6 or 1/2, which is not a high or low probability.
