Answer:
The standard deviation of the number of customers that might check out between 10.15 am and 10.30 am is 2.4.
Step-by-step explanation:
We have the mean during a time interval, so the Poisson distribution is used.
Poisson distribution:
In the Poisson distribution, the standard deviation is the square root of the mean.
Typically, from 10 am to 11 am, I get 23 customers.
In an hour, you get 23 customers.
What is the standard deviation of the number of customers that might check out between 10.15 am and 10.30 am?
In this period, there are 15 minutes, that is, one fourth of an hour, so:
And the standard deviation will be the square root of the mean, so:
The standard deviation of the number of customers that might check out between 10.15 am and 10.30 am is 2.4.

Answer:
∠HIJ = 57
∠IJH = 57
∠JHI = 66
Step-by-step explanation:
As a much better answer to the other guy:
You first have to find what the sum of the interior angles are. This can be found using the following expression:
<em>( n - 2 ) × 180</em>
Where 'n' is the number of sides of a polygon. Since this is a triangle:
<em>n = 3</em>
Therefore, the sum the interior angles of a triangle is 180°
Returning to the triangle, it's stated that the <u>triangle is isosceles,</u> meaning the ∠HIJ is the same as the ∠IJH (the middle point notating the position of the angle.) So then you have 3 angles with the following expressions:
∠HIJ = 5x + 2
∠IJH = 5x + 2
∠JHI = 3x + 33
Since all of the angles need to add up to 180°, we can smush them all into one big equation:
5x + 2 + 5x + 2 + 3x + 33 = 180
If you simplify everything:
13x + 37 = 180
Subtract 37:
13x = 143
Divide by 13:
x = 11
Now that you have x, plug it in to the equations above!
∠HIJ = 5(11) + 2
∠IJH = 5(11) + 2
∠JHI = 3(11) + 33
Simplify.
∠HIJ = 55 + 2
∠IJH = 55 + 2
∠JHI = 33 + 33
Again.
∠HIJ = 57
∠IJH = 57
∠JHI = 66
There you go!
