The mean means average. To find it, add together all of your values and divide by the number of addends. The median is the middle number of your data set when in order from least to greatest. The mode is the number that occurred the most often. The range is the difference between the highest and lowest values.

Elaine has invested $575 in a stock that is expected to double every 8 years. What will be the value of the stock in 16 years?
Sloan [31]
The correct option is D.
The initial value of the stock is $575 and it doubles every 8 years, this means that, in the next eight year the value of the stock will be 2 * 575 = $1150.
This amount too will double in the next eight year and the value will become 2* 1150 = $2,300.
Therefore, in 16 years time the share will be worth $2,300.00.

Use the trigonometric subtraction formula for sine to verify this identity: sin((π / 2) – x) = cos x
KIM [24]

Answer:

Step-by-step explanation:

sin (\frac{\pi}{2} - x) = cos x \\\\ sin (a - b) = sin a.cos b - sin b.cos a \\\\ sin (\frac{\pi}{2} - x) = sin \frac{\pi}{2}.cos x - sin x.cos \frac{\pi}{2} \\\\ sin \frac{\pi}{2} = 1; cos \frac{\pi}{2} = 0 \\\\ sin (\frac{\pi}{2} - x) = 1.cos x - sin x.0 \\\\ sin (\frac{\pi}{2} - x) = cos x
