Answer 1

Answer: I think 12. I'm not sure though. The way I came up with that answer is the tree diagram. I used the numbers 1, 2, 3, 4, . Then I did the tree diagram method.

As a company manager for the Quick Money Business there is a 0.40 probability that you will be promoted this year. There is a 0.72 probability that you will get a promotion or a raise. The probability of getting a promotion and a raise is 0.25. If you get a promotion, what is the probability that you will get a raise?

Answers

Answer:

Probability of getting raise when you get promoted = 0.625

Step-by-step explanation:

We have to find the probability of getting a raise. So,

Promotion = P, Raise = R

First we find if you get the promotion, what is the probability that you will also get a raise

$P(R | P) = (P(P \& R))/(P(P)) = \frac {0.25}{0.4} = 0.625$

Probability of getting raise when you get promoted = 0.625.

Now we find the probability of getting a raise,

$P(P\ or\ R) = P(P) + P(R) - P(P \& R)\n\0.72 = 0.4 + P(R) - 0.25\nP(R) = 0.72 - 0.4 +0.25\nP(R) = 0.57$

So, the probability of getting raise = 0.57.

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

Which of the following is the function representing the graph below? graph begins in the third quadrant near the line y equals negative 3 and increases slowly while crossing the ordered pair 0, negative 2. When the graph enters the first quadrant, it begins to increase quickly throughout the graph.f(x) = 4x
f(x) = 4x − 3
f(x) = 4x + 3
f(x) = 4(x + 3)

Answers

Answer:

f(x) = 4^x -3

Step-by-step explanation:

All of the listed functions are linear functions with a constant slope of 4. None of them goes through the point (0, -2).

So, we assume that there is a missing exponentiation operator, and that these are supposed to be exponential functions. If the horizontal asymptote is -3, then there is only one answer choice that makes any sense:

f(x) = 4^x -3

The minimum value of 4^z for any z will be near zero. In order to make it be near -3, 3 must be subtracted from the exponential term.
