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

What is the rate of change for a linear function that passes through the points (8, -10) and (-6, 14)
Anna71 [15]

Answer: m=-1.714

Step-by-step explanation:

By definition, the slope of the line is described as "Rate of change".

You need to use the following formula to calcualte the slope of the line;

m=\frac{y_2-y_1}{x_2-x_1}

In this case you know that the line passes through these two points: (8, -10) and (-6, 14).

Then, you can say that:

y_2=-10\\y_1=14\\\\x_2=8\\x_1=-6

Knowing these values, you can substitute them into the formula for calculate the slope of a line:

 m=\frac{-10-14}{8-(-6)}

Finally, you must evaluate in order to find the slope of this line. You get that this is:

m=\frac{-24}{8+6}\\\\m=\frac{-24}{14}\\\\m=-\frac{12}{7}\\\\m=-1.714

Let f(x)=8/(1+3e)^(-0.7x)
Troyanec [42]
For x = -3, <span>(-0.7x) equals (-0.7[-3]), or 2.1.
 
                                8                   8                       8
Then f(-3) =  ------------------- = ---------------- = ------------ = 0.31 (approx)
