Answer:
324cm^3
Step-by-step explanation:
The formula for calculating volume of a triangular prism is 1/2× bhl (b : base, h : height, l : length)
1/2 × 6 × 9 × 12 = 324cm^3
Answer:
The interval that contains the middle 68% of the heights is from 52 inches to 60 inches.
Step-by-step explanation:
The empirical rule states that, for a normally distributed variable:
The middle 68% of the measures are within 1 standard deviation of the mean.
The middle 95% of the mesures are within 2 standard deviations of the mean.
The middle 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Normally distributed with mean 56 inches and standard deviation 4 inches.
So the interval that contains the middle 68% of the heights is from 52 inches to 60 inches.
I think that it is a. Identity bc if you work it out you see that it is A. Identity
Answer:
C
Step-by-step explanation:
River valley provided fertile land and access to water.
Not:
dense forests: hard to navigate, not suitable for ancient civilizations
mountain passes: same reason as above
smooth coastlnes: settlements potentially could be washed away or destroyed. Access to fresh, non-salt water, also was harder than that of settling in river valleys
