50 people took a driving test. 18 of the 50 people are women. One quarter of the men failed the driving test. The number of men who passed the driving test was 8 more than the number of women who passed the test. A person is chosen at random. What is the probability that they passed the driving test? Write your answer as a decimal.

 The probability is  0.8

Step-by-step explanation:

Total who took the test = 50

Women who took the test = 18

50 - 18 = 32  is the number of men

32/4 = 8    men who did not pass

Men who passed = 32 - 8 =24

To find the number of women who passed :  24 - 8 = 16

Total  of people who passed = 24 + 16 = 40

Number who passed out of total people  = 40/50   Converted ro decimal: 0.8

So the probability of randomly selecting a person who passed is 0.8

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
