Mathematics
1 answer:
IRINA_888 [86]3 years ago
3 0

Answer:

I wasn't sure if you meant centimeters, inches or degrees. But since I don't know, I'll answer all three.

Step-by-step explanation:

Centimeters- Possible

Inches- Possible (Extremely big. I suggest using a big whiteboard to draw out)

Degrees- Impossible (All degrees in a triangle have to add up to 180)

<span>Standard deviation of first data set = 5879.1 Standard deviation of second data set = 14768.78 The second data set is more variable. The basic definition of standard deviation is the square root of the mean of the squares of the difference from the mean. It's a bit of a mouthful, but easy enough to do. For the first data set, first calculate the mean. (28995 + 37534 + 31361 + 27087 + 20966 + 37741) / 6 = 30614 Now calculate the square of the differences from the mean (28995 - 30614)^2 = 2621161 (37534 - 30614)^2 = 47886400 (31361 - 30614)^2 = 558009 (27087 - 30614)^2 = 12439729 (20966 - 30614)^2 = 93083904 (37741 - 30614)^2 = 50794129 And now the average of the squares (2621161 + 47886400 + 558009 + 12439729 + 93083904 +50794129) / 6 = 34563888.67 And finally, take the square root to get the standard deviation. sqrt(34563888.67) = 5879.1 Now for the second data set of western states. First, the mean (72964 + 70763 + 101510 + 62161 + 66625 + 54339) / 6 = 71393.67 Now the squares of the differences (72964 - 71393.67)^2 = 2465946.778 (70763 - 71393.67)^2 = 397740.4444 (101510 - 71393.67)^2 = 906993533.4 (62161 - 71393.67)^2 = 85242133.78 (66625 - 71393.67)^2 = 22740181.78 (54339 - 71393.67)^2 = 290861655.1 And the average of the squares is 218116865.2 Finally, the square root of the average is 14768.78 So the standard deviation of the 2nd data set is 14768.78 And since the standard deviation of the 2nd data set is larger than the standard deviation of the 1st data set, that means that the 2nd data set is more variable.</span>

Help please geometry !
Leona [35]
If you use the same technique from the first question, you can do:

5x+2=3x+42
2x=40
x=20

For the rest of the questions, please use the same technique if they are vertical because I can't solve all of the questions for you sorry.

A total of 133 million square miles of the Earth's surface are covered in water. The ratio of the area covered in water to the a
Anni [7]

Answer:

  • 57 million square miles

Step-by-step explanation:

Let the area of water is w and area of land is l.

<u>Their ratio is:</u>

  • w/l = 7/3

or

  • 133 / l = 7/3

Find the value of l

  • l = 133*3/7
  • l = 57 million square miles
