Answer:

See picture attached

Step-by-step explanation:

The graph of a non-proportional linear relationship is a line that does not cross through the origin. The graph of a proportional linear relationship does.

Given the general expression of a line: y = ax + b, where a and b are constants, if b is equal to zero, the line cross through the origin, otherwise the line inercept y-axis at value of b.

Direct variation means that y = kx, where k is a constant, then is a proportional linear relationship.

Given a cell phone company charges $19.95 per month for the first 2G, then $5 per gig over the initial 2G; the graph is a non-proportional linear relationship because the cost is never zero and the graph  does not cross through the origin.

Given a cell phone company charges $29.95 per month always, then the cost is never zero and the graph  does not cross through the origin.

lana [24]

Answer:

C)150

Step-by-step explanation:

P (blue)  fraction = 2/8   decimal=.25     percent=25%

P(purple) fraction=0/8   decimal=0         percent =0%

P(not green)  fraction=5/8     decimal=.625     percent= 62.5%

P(not brown) fraction=8/8     decimal=1   percent =100%

2)Refer to the table on air travel selected airports. Suppose a flight that arrived at El Centro is selected at random. What is the probability that the flight did not arrive on time? write your answer as a fraction, decimal and percent.    

80% on time so 20% are not on time

20/100 ÷ 20 =1/5

20%, .2, 1/5

3)The spinner has 8 sectors labeled with letters. Each sector of the spinner below is the same size, as shown.

If the arrow is spun 400 times , how many times  would it be  expected to land on a sector labeled B?

A)50                 C)150

B)100                D)250
