Find the value of x (3x+38)5x

Answers

Answer:

Step-by-step explanation:

3x = -38 + 5x

3x + -5x = -38 + 5x + 5x

3x + -5x = -2x

-2x = -38 + 5x + -5x

5x + 5x =0

-2x = -38 + 0

-2x = -38

-2x / -12 = 38 / -2

Rewrite with only sin x and cos x. (1 point)sin 2x - cos 2x

2 sinx cosx - 1 + 2 sin2x
2 sin x cos2x - 1 + 2 sin2x
2 sin x cos2x - sin x + 1 - 2 sin2x
2 sin x cos2x - 1 - 2 sin2x

Answers

Note that
sin 2x = 2 sin(x) cos(x)
cos 2x = cos²x - sin²x = 2cos²x - 1 = 1 - 2sin²x

Therefore
sin 2x - cos 2x
= 2 sin(x) cos(x) - (1 - 2sin²x)
= 2 sin(x) cos(x) - 1 + 2sin²x

Answer: 2 sin(x) cos(x) - 1 + 2 sin²x

Suppose you just received a shipment of twelve televisions. Three of them are defective. Assuming that two televisions are randomly selected, find the following probabilities:What is the probability that both televisons work?
What is the probability that at least one does not work?

Answers

The probability that both televisons work is 18/33.
The probability that at least one does not work is 15/33.

Let x = number of shipments, x = 12
P(defective) = 3/12
P(working) = 9/12
The probability that two randomly selected televisions are both working is:
9/12 * 8/11 = 72 / 132 or 18/33
P(2 working) = 18/33
8/11 is used for the second selection since the number of televisions has been reduced due to the first selection.

The probability of 1 not working among the two can be solved through"
P(at least one defective among the 2) = 1 - P(2 working)
P(at least one defective among the 2) = 15/ 33
