The right rectangular prism below is made up of 8 cubes each cube has an edge length of 1/2 inch what is the volume of this pris
1 answer:
Answer:
1 cubic inches
Step-by-step explanation:
No of cubes = 8
Edge length of each cube = 1/2 inch
Volume of cube is given where edge is the edge length
Thus volume of cube with Edge length is calculated as explained below
Question states that there are 8 such cubes joined to make a right rectangular prism. Thus volume of right rectangular prism will be sum of volume of 8 such cubes.
volume of right rectangular prism = 8 times the volume of 1/2 inched cubes
= 8* 1/8 = 1 cubic inches
Thus volume of right rectangular prism is 1 cubic inches.

Answer:
0.381 is the probability that the number of drivers will be at most 18.
Step-by-step explanation:
We are given the following information in the question:
The number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20.
- The Poisson distribution is the discrete probability distribution of the number of events occurring in a given time period, given the average number of times the event occurs over that time period.
- The variance of Poisson distribution is equal to the mean of Poisson distribution.
a) P(number of drivers will be at most 18)
Formula:
Thus, 0.381 is the probability that the number of drivers will be at most 18.
