Answer:

Second choice, 2/5

Step-by-step explanation:

12 + 9 + 10 + 11 + 8 = 50

12 red and 8 blue, the probability of getting either is 12 + 8 = 20/50 which simplified is 2/5

What is the simplest form of 4a + 8b/12​<br> Step by step pls
shutvik [7]

Answer:

4a + 2b/3

Step-by-step explanation:

focus on 8b/12 first:

factor 8b/12 by 4 ---> 8b/12 = 4(2)b/4(3) ----> cancel 4 in the denominator and the nominator ---> 8b/12 = 4(2)b/4(3) = 2b/3

then, go back to 4a:

4a is in its simplest form, it can't be factor

therefore, plus 4a and 2b/3 = 4a + 2b/3

What is the standard form of function f?
Tomtit [17]

Answer:

A = 4; B = -1 ; C = -29

Step-by-step explanation:

y = 4(x + 6) + 5

y = 4x + 24 +5

y = 4x + 29

Standard form: Ax + By = C

 4x - y = -29

From the given discrete distribution, we have that:

\mu = 2.13, \sigma^2 = 0.61, \sigma = 0.78

<h3>What are the mean, the variance and the standard deviation of a discrete distribution?</h3>
  • The mean of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
  • The variance is given by the sum of the difference squared between each observation and the mean, divided by the number of values.
  • The standard deviation is the square root of the variance.

In this problem, the distribution is:

P(X = 1) = \frac{2}{8}

P(X = 2) = \frac{3}{8}

P(X = 3) = \frac{3}{8}

Hence, the mean is:

\mu = 1\frac{2}{8} + 2\frac{3}{8} + 3\frac{3}{8} = \frac{17}{8} = 2.13

The variance is:

\sigma^2 = (1-2.13)^2\frac{2}{8} + (2-2.13)^2\frac{3}{8} + (3-2.13)^2\frac{3}{8} = 0.61

The standard deviation is:

\sigma = \sqrt{0.61} = 0.78
