4x² - 9x² + 5 = 0
4x² - 4x - 5x + 5 = 0
4x(x - 1) - 5(x - 1) = 0
(4x - 5)(x - 1) = 0

Set each binomial equal to zero. 

4x - 5 = 0
4x = 0 + 5
4x = 5
x = 5/4

x - 1 = 0
x = 0 + 1
x = 1

Your solutions are x = 1, 5/4

the probability that we encounter a green light at the corner of college and main is 0.35, a yellow light 0.04, and a red light
Ostrovityanka [42]

Answer:

21% probability you will hit a green light on monday and a red light on tuesday

Step-by-step explanation:

When two events, A and B, are independent, we have that:

P(A \cap B) = P(A) \times P(B)

In this problem, we have that:

Event A: Green light on monday.

Event B: Red light on tuesday.

The probability that we encounter a green light at the corner of college and main is 0.35

This means that P(A) = 0.35

The probability that we encounter a red light is 0.61:

This means that P(B) = 0.61

These events are independent, that is, the light color on Tuesday is independent of the color on Monday. So

P(A \cap B) = P(A) \times P(B) = 0.35 \times 0.6 = 0.21

21% probability you will hit a green light on monday and a red light on tuesday
