The speed of nitrogen molecules in the atmosphere (at 20ºC) follows a normal distribution with a mean speed of 500 meters/second

and a standard deviation of 50 meters/second. Which conclusion does this information best support?
84% of the molecules have speeds between 450 meters/second and 550 meters/second.

68% of the molecules have speeds between 450 meters/second and 550 meters/second.

50% of the molecules have speeds between 450 meters/second and 550 meters/second.

34% of the molecules have speeds greater than 550 meters/second.

Your company is hosting a benefit 5 kilometer race How long will the race be to the nearest tenth of a mile?
8090 [49]
In this question the main part is to convert the kilometer to miles and then writing the answer to the nearest tenth of a mile. the information given in the question is that the race is for a distance of 5 kilometers.
Now we already know
1 km = 0.6214 mile
Then
5 km = ( 0.6214 * 5) miles
         = 3.107 miles
         = 3.11 miles
So the actual distance when converted to miles will be 3.11 miles. I hope this is the answer you were looking for. This is the simplest way for doing such problems and in future you can follow this method to find the answers without the need of any help.

If the points (2,7),(-3,3) and (5,1) are the vertices of a triangle ,find the length of the median drawn through the first verte
Bingel [31]

Answer:

  • \sqrt{26} units

Step-by-step explanation:

The median is the line segment connecting the vertex with the midpoint of the opposite side.

<u>The midpoint has coordinates:</u>

  • x = (-3 + 5)/2 = 2/2 = 1
  • y = (3 + 1)/2 = 4/2 = 2

<u>Use the distance formula to find the distance between points (2, 7) and (1, 2):</u>

  • <u />d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
  • d=\sqrt{(1- 2)^2+(2-7)^2} =\sqrt{1+25} =\sqrt{26}
