Answer:

Step-by-step explanation:

Volume of a hemisphere = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]

=> 18π = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]

=> 18 = [tex]\frac{2}{3}[/tex][tex]r^{3}[/tex]

=> [tex]r^{3}[/tex] = 18 × [tex]\frac{3}{2}[/tex]

=> [tex]r^{3}[/tex] = 27

=> r = [tex]\sqrt[3]{27}[/tex]

=> r = 3 inches

Therefore, the radius of the hemisphere in inches is 3 inches.

Find the mean, median, and mode of the data set. Round to the nearest tenth.

5, 7, 2, 6, 7, 10, 12, 7, 9, 13, 5

Answers

Answer:

The mean is 7.5.

The median is 7.

The mode is 7.

Step-by-step explanation:

To find the mean, add up all the numbers in the data set and then divide the sum by the total number of values.

5 + 7 + 2 + 6 + 7 + 10 + 12 + 7 + 9 + 13 + 5 = 83

83 divided 11 equals 7.5.

To find the median, arrange all the numbers in the data set from smallest to largest and then find the number that is in the middle of the set.

To find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode.

the mean is 7.5 the median is 7 and more is 7

The number without the variable (the letter x) is referred to as the y intercept. Therefore, it refers to the point along the y axis (up and down). For instance, in the first problem, the y intercept is -3. You would then go down 3 spaces and draw in the point.

The slope always has the x variable next to it. For instance, the slope of the first question is (positive) 2. To graph that, you would go up 2, and to the right one. Then you would repeat.

Our atmosphere acts like a blanket trapping heat and keeping Earth at a habitable temperature, its this retaining of heat that is referred to as the Greenhouse Effect. The greenhouse effect is caused by greenhouse gases that trap heat from the sun, the more greenhouse gases there are the more heat is retained HOW IT WORKSThe heat from the sun (solar radiation) has a very short wavelength and this can pass easily through the layer of greenhouse gases. This wavelength is called Ultraviolet radiation. As the UV rays strike the Earth, the Earth redirects the rays back into the atmosphere. We feel this as heat. The heat from the earth (terrestrial radiation) has a longer wavelength (infrared) some of this becomes trapped by the layer of greenhouse gases. GREENHOUSE GASESWater vapor (H20) is the most prevalent greenhouse gas and occurs naturally. Some greenhouse gases are both natural and man-made including carbon dioxide (CO2) & methane (CH4).
