Answer:
The registered passengers vehicle is he population and the one that are electro-gas hybrids forms a sample of the population.
Step-by-step explanation:
We are given the following in the question:
The U.S. Department of Transportation announces that of the 250 million registered passenger vehicles in the US, 2.1% are electro-gas hybrids.
Population and sample:
- Population is collection of all the observations of individuals of interest.
- Sample is a subset of population.
- Population is always larger than the sample.
- Population is the universal set of all observations.
Thus, for the given case,
Individual of interest:
250 million registered passenger vehicles in the US
Population of interest:
250 million registered passenger vehicles in the US
Sample:
2.1% electro-gas hybrids.
Thus, the registered passengers vehicle is he population and the one that are electro-gas hybrids forms a sample of the population.
270/15 = 135/ 7.5
cross multiply to see if it is a true proportion
(15)(135) = (270)(7.5)
2025 = 2025 (correct...so this is a true proportion)
answer is : bottom right one
So, the base is 20 and you will multiply the base by the height which is 15 so if you want it with the triangles and squares then, you break down the parallelogram into 2 triangles and 1 square you will get the height of the 2 triangles and the square and add them all up and you should get 300 if you need me to explain better i will!
Probability that no zebras collide is 0.25
The zebras are represented as z1, z2 and z3.
Z1 to B, Z2 to C, and Z3 to A come first 
Following that, z1 to C, z2 to A, and z3 to B = 
Consequently, the likelihood of no collision is 2×1/8 = 0.25.
<h3>
What are the types of probability distributions ?</h3>
Discrete and continuous probability distributions are the two main categories in which probability distributions fall. There are numerous varieties of probability distributions within each category.
- The number of favorable outcomes of an event divided by the total number of possible outcomes of an event can be used to calculate the probability of an event.
- The likelihood of a sure or certain event is one.
- The likelihood of an impossibility is 0 (0).
- Every event has a probability between 0 and 1.
