Answer:

X = -6

Step-by-step explanation:

calculate the sum (6+2)

3 x -2=-20

Move constant to the right- hand side and change its sign

(3x--20+<u>2</u>)

calculate the sum

3x=-18

divide both sides by 3

= -6

hope this helps!

Answer:

x = -6

Step-by-step explanation:

3x-6+4=-20

Combine like terms

3x -2 = -20

Add 2 to each side

3x-2+2 = -20 +2

3x = -18

Divide each side by 3

3x/3 = -18/3

x = -6

gulaghasi [49]

Since it is not perfectly straight it’s not linear so

*nonlinear association

The line goes down not up so it’s

*negative association

If your teacher wants to count the point outside of the regular line it would be no association

The two that most fit this graph are nonlinear and negative association

What is the standard deviation of a random variable q with the following probability distribution? (Do not round intermediate ca

stiks02 [169]

Answer:

The standard deviation of given probability distribution is 0.8292

Step-by-step explanation:

We are given the following in the question:

q: 0 1 2

Probability: 0.25 0.25 0.50

Formula:

$E(q) = \displaystyle\sum q_ip(q_i)\\=0(0.25) + 1(0.25) + 2(0.50) = 1.25$

$E(q^2)= \displaystyle\sum q_i^2p(q_i)\\=0^2(0.25) + 1^2(0.25) + 2^2(0.50) = 2.25$

Variance =

$\sigma^2 = E(q^2) = (E(q))^2\\= 2.25- (1.25)^2\\=0.6875\\\sigma = \sqrt{0.6875} = 0.8292$

Thus, the standard deviation of given probability distribution is 0.8292
