Lady_Fox [76]

Answer:

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean is:

$M = \frac{a+b}{2}$

The standard deviation is:

$S = \sqrt{\frac{(b-a)^{2}}{12}}$

Arrival time of 9:18 am and a late arrival time of 9:41 am.

9:41 is 23 minutes from 9:18. So the time is uniformily distributed between 0 and 23 minutes, so a = 0, b = 23.

Mean:

$M = \frac{a+b}{2} = \frac{0+23}{2} = 11.5$

Standard deviation:

$S = \sqrt{\frac{(b-a)^{2}}{12}} = \sqrt{\frac{(23 - 0)^{2}}{12}} = 6.64$

The mean is 11.5 minutes and the standard deviation is of 6.64 minutes

NEED THE ANSWER ASAP! Find the measure of the missing angle X

jasenka [17]

Answer:

50°

In order to determine the unknown angle, be sure to use the total sum of 180° 

120° - 180°= 60° ( this give you the red side inside the triangle)

Then you simple add the two number inside the triangle

60° + 70° = 130°( then you use this to find the missing corner by subtracting from 180°)

180°- 130° = 50° this is your missing angle X"

To prove it simple add all the 3 angles inside the triangle add up to 180°

60° + 70° + 50° = 180°

X = 50°
