First, find the mean. You'll need it to compute the variance.
The variance of the sample is then computed with the formula
The standard deviation is the square root of the variance, so
Volume- LxWxH
30x10x50= 15000
Answer: 5, -4, 2.6, and 100
Step-by-step explanation:
Ok, so we know that RST is equal to 6x+12
And RST is also equal to 78 + 3x-12
so we set them equal to each other
6x + 12 = 3x - 12 + 78
And simplify
3x = 54
x = 18
Finally, we solve for the angle with 18 for x
6(18) + 12
108 + 12
120
Hope this helps
Answer:
imaginary
Step-by-step explanation:
from the working strp, we know that the number is imaginary
we can't square root the negative number
