-Essay question-
What causes wind?
the constant density of the air
the temperature differences of the hemispheres
the circulating air currents.
the movement of the Earth's axis.
How do ocean currents impact the climate?
Ocean currents change the temperature of air masses. Warm ocean currents transport heat from the equator to the poles.
Ocean currents change the temperature of landmasses. Warm ocean currents transport heat from the equator to the poles.

What causes days to be cooler on one part of Earth than on another?
A. the angle at which the sun strikes Earth
You try first.
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.

The stem-and-leaf plot shows the heights in centimeters of Teddy Bear sunflowers grown in two different types of soil.
Soil A Soil B
5 9
5 2 1 1 6 3 9
5 1 0 7 0 2 3 6 7 8
2 1 8 3
0 9
Key: 9|6 means 69 Key: 5|8 means 58
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.
What is the probability of rolling a number less than or equal to 6 when rolling a six-sided number cube?
A. 0.17
B. 5%
C. five sixths
D. 1.0
The correct answer is D. 1.0.
When rolling a standard six-sided number cube, there are six possible outcomes: 1, 2, 3, 4, 5, or 6. All of these outcomes are less than or equal to 6. Therefore, the probability of rolling a number less than or equal to 6 is 1 or 100%.
