Answer:
125 cm^3
Step-by-step explanation:
Find THE volume of this cube of side length 5 cm:
Volume of a cube is V = s^3, where s is the side length.
Here, V = (5 cm)^3 = 125 cm^3
Answer:
Critical value:
The 90% confidence interval for the population mean bromide concentration is (0.376, 0.39).
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so . This value of z is the critical value
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the mean subtracted by M. So it is 0.383 - 0.0066 = 0.376 cc/cubic meter
The upper end of the interval is the mean added to M. So it is 0.383 + 0.0066 = 0.39 cc/cubic meter
The 90% confidence interval for the population mean bromide concentration is (0.376, 0.39).
Answer:
A hexagon has six angles. A full circle is 360°; since there are 6 angles in the hexagon, it will rotate onto itself every 360/6 = 60°. This means that the hexagon will rotate onto itself at angles that are multiples of 60°; this means that 120° and 180° will also do this.
