Answer:

x = -2

Step-by-step explanation:

Solution:

-5x - 5y = 25    -(1)

3x + 5y = -21     -(2)

Adding (1) and (2),

-5x - 5y + 3x + 5y = 25 - 21

-5x + 3x -5y + 5y = 4

-2x = 4

x = 4 / -2

Therefore, x = -2

Suppose that P (A)=0.4 AND P (B)=0.2, If events A & B ARE Mutually EXCLUSIVE :
baherus [9]

Part (a) Finding the probability of either A or B

We are told that events A and B are mutually exclusive. This means they cannot happen at the same time. We can say P(A and B) = 0

Furthermore,

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.4 + 0.2 - 0

P(A or B) = 0.6

<h3>Answer:  0.6</h3>

=======================================================

Part (b) Finding the probability of neither A nor B

P(A or B) + P(neither A nor B) = 1

P(neither A nor B) = 1 - P(A or B)

P(neither A nor B) = 1 - 0.6

P(neither A nor B) = 0.4

The reason why this works is to imagine throwing a dart at the Venn diagram. You'll either...

  • you land in A or B (pick one but not both), OR,
  • you'll land outside both regions A and B.

One or the other must happen. Both events cannot happen simultaneously.

<h3>Answer: 0.4</h3>

riadik2000 [5.3K]

Answer:

84

Step-by-step explanation:

first calculate the rectangle (6* 10  = 60) and then add that to the area of the triangles. 1/2(4) * 6= 2 * 6 = 12, and since there are two triangles: 12* 2 = 24, add that to the area of the rectangle and you get 84.
