Answer: C.-1.5
Step-by-step explanation:
Given: The burning time of a very large candle is normally distributed with mean of 2500 hours and standard deviation
 of 2500 hours and standard deviation of 20 hours.
 of 20 hours. 
Let X be a random variable that represent the burning time of a very large candle.
Formula: 
For X = 2470

So, the z-score they corresponds to a lifespan of 2470 hours. =-1.5
Hence, the correct option is C.-1.5.

<u><em>Answer:</em></u>
The shorter leg is  inches
 inches
<u><em>Explanation:</em></u>
The 30°-60°-90° is a special type of right-angled triangles
<u>It has the following special side length:</u>
The length of the side opposite to the 30° is  the length of the hypotenuse
 the length of the hypotenuse
The length of the side opposite to the 60° is  of the hypotenuse
 of the hypotenuse
<u>Now, we know that</u> the lengths of the sides in a triangle are proportional to the angles
<u>This means that</u> the shortest side will be the one opposite to the smallest angles
In our case, the shortest side will be the one opposite to the 30° angle
We are given that the hypotenuse of the triangle is  in
 in
<u>From the above:</u>
Shorter leg = leg opposite to 30° =  inches
 inches
Hope this helps :)
