Suppose P( A) = 0.60, P( B) = 0.85, and A and B are independent. The probability of the complement of the event ( A and B) is: a

diamong [38]

Answer: a. 0.4 × 0.15 = 0.060

Step-by-step explanation: Probability of the complement of an event is the one that is not part of the event.

For P(A):

P(A') = 1 - 0.6

P(A') = 0.4

For P(B):

P(B') = 1 - 0.85

P(B') = 0.15

To determine probability of A' and B':

P(A' and B') = P(A')*P(B')

P(A' and B') = 0.4*0.15

P(A' and B') = 0.06

<u>Probability of the complement of the event is 0.060</u>

The table represents a linear function. <br><br> What is the slope of the function?

otez555 [7]

Answer:

-6

Step-by-step explanation:

The slope of a line is given with the formula

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

Using the first two points, (-2, 8) and (-1, 2), we have

m = (2-8)/(-1--2) = -6/(-1+2) = -6/1 = -6

The function y=ex is vertically stretched by a factor of 2, reflected across the x-axis, and then shifted down 3 units, find the

Anettt [7]

Answer:

$y = - 2 e^{x} - 3$

Step-by-step explanation:

We have to vertically stretch the function $y = e^{x}$ by a factor of 2.

Then the function will become $y = 2e^{x}$ .

Then it is reflected across the x-axis.

So, the new function will be $y = - 2e^{x}$ .

Now, if the function is shifted down 3 units then the final function will become $y = - 2 e^{x} - 3$ (Answer)
