Answer:

Step-by-step explanation:

A probability distribution is one which gives various values of a random variable X along with assigned probabilities

The conditions for probabilities is each probability should be positive andlying between 0 and 1. Also total of the probabilities should equal 1.

COmparing this with the given tables we find that I one total probability

=1.5 hence cannot be a prob distribution

Second distribution has unequal probabilities between 0 and 1 but total is 1.4 hence cannot be a prob distn.

III one has all probabilities equal to 0.2 a value between 0 and 1 and total prob =1 This tallies with the graph with equal probabilities. Hence option III is the right answer

we find that table 4 total probability

=1.5 hence cannot be a prob distribution

So answer is option 3

when graphed on a coordinate plane, Bumby avenue can be represented by the equation y=-4x-7. Primrose Avenue can be represented

erastova [34]

Answer:

Bumby Avenue is represented by the line:

y = -4*x - 7.

Primrose Avenue can be represented with:

8x + 2y = 17.

We may want to find the point where both avenues intersect.

Let's isolate y in this second equation:

2y = 17 - 8x

y = 17/2 - 8x/2 = -4*x + 17/2

Now we can see that the equation for Primrose Avenue has the same slope than the equation for Bumby Avenue, and when two linear equations have the same slope, means that the lines are parallel.

Then we can conclude that Primrose Avenue and Bumby Avenue are parallel, so they never meet eachother.
