To find the volume, you do area multiplied by thickness( or height)
In this example, you do (1/2*9*6)*10 which is 270
hope I helped ;)
Answer:
The possible values of x are 90°, 30° and 150°.
Step-by-step explanation:
Given that,
sin(2x) = cos(x) where 0° ≤ x < 180°
We know that, sin(2x) = 2 sinx cosx
2 sinx cosx = cosx
Subtract cosx on both sides
2 sinx cosx - cosx = 0
cosx (2sinx-1)=0
It means, cosx = 0 and (2sin x -1 ) = 0
cos x = cos0 and sinx = 1/2
x = 90° and x = 30°, 150°
Hence, the possible values of x are 90°, 30° and 150°.

Answer:
The true mean 
it probably could be larger, smaller, or equal to 22
Step-by-step explanation:
False.
By definition the sample mean is defined as:
For this case the value for the sample size is n =190 and the calculated sample mean is 
. This value represent the sample and for this case we can't assume that this value represent at all the population as the population mean since we probably have variability from the data of the students at City College.
So we can conclude that the true mean it probably could be larger, smaller, or equal to 22
