Based on recent experience, ten-year-old passenger cars going through a motor vehicle inspection station have an 80% chance of passing the emissions test. Suppose that two hundred such cars will be checked out next week. Find the number of cars that are expected to pass.

160

Step-by-step explanation:

The chance/probability of 10-year-old passenger cars passing an emission test is 80%.

200 10-year-old passenger cars will be tested next week.

How many of the 200 cars are expected to pass the emission test?

If there is an 80% chance of them passing the test then it means that 80% of the cars pass the test at any given time.

80% of 200 = 0.8 × 200 = 160

Hence, 160 (of the 200) cars are expected to pass the test.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
