Mathematics

solong [7]3 years ago

Answer:The probability of the complement of an event is one minus the probability of the event. Since the sum of probabilities of all possible events equals 1, the probability that event A will not occur is equal to 1 minus the probability that event A will occur.

Step-by-step explanation:Complement of an Event: All outcomes that are NOT the event. So the Complement of an event is all the other outcomes (not the ones we want). And together the Event and its Complement make all possible outcomes.

Help I’m so confused

Answer:

y = 3x + 6

Step-by-step explanation:

The domain is you x values. You need to substitute the x values into both functions to see which one produces the plots on the graph.

<h3>y = 2x + 4</h3>

when x = -3, y = 2(-3) + 4 = -6 + 4 = -2

when x = -2, y = 2(-2) + 4 = = -4 + 4 = 0

when x = -1, y = 2(-1) + 4 = = -2 + 4 = 2

when x = -0, y = 2(0) + 4 = 0 + 4 = 4

<h3>y = 3x + 6</h3>

when x = -3, y = 3(-3) + 6 = -9 + 6 = -3

when x = -2, y = 3(-2) + 6 = = -6 + 6 = 0

when x = -1, y = 3(-1) + 6 = = -3 + 6 = 3

when x = -0, y = 3(0) + 6 = 0 + 6 = 6

The points on the graph are (-3, -3), (-2, 0), (-1, 3) and (0, 6)

This is same as the results from the function y = 3x + 6

I need help because I don’t know what they are asking
Mashutka [201]

Answer:

  16x -2

Step-by-step explanation:

You know how to compute the perimeter of a rectangle of length L and width W:

  P = 2(L+W)

Here, you're asked to use the given algebraic expressions for length and width and simplify the result of putting those in the perimeter formula.

  P = 2((5x-2) +(3x+1))

  P = 2(8x -1)

  P = 16x -2 . . . the perimeter of the rectangle
