A student wrote the equation of this line as y=1/5x. What mistake did she nake?
galina1969 [7]
The student is wrong in not putting a parenthesis between 1/3 and x. An equation of a line has a general equation of y = mx + b where m is the slope and b is the y-intercept. In this case, most likely 1/3 is the slope and 0 is the y-intercept. However, writing the equation like that seems like the x variable is a denominator and if that is the case the equation will not represent a line already.

A used car dealer sells SUVs and cars. Of all the vehicles, 60% are cars. Of all the vehicles, 15% are red cars. What is the pro
kramer

Answer:

The probability that a car chosen at random is not red is 75%.

Step-by-step explanation:

Given that a used car dealer sells SUVs and cars, and of all the vehicles, 60% are cars, and of all the vehicles, 15% are red cars, to determine what is the probability that a car chosen at random is not red you must perform the following calculation:

60 = 100

15 = X

15 x 100/60 = X

25 = X

100 - 25 = 75

Therefore, the probability that a car chosen at random is not red is 75%.
