Answer:

x = 24

Step-by-step explanation:

Simplify

( 3 x +10 ) − ( 2 x − 9 )

Simplify each term.

Apply the distributive property.

3 x + 10 − ( 2 x)− = 43

Multiply 2 by − 1 .

3 x + 10 − 2 x − − 9 = 43

Multiply − 1 by − 9 .

3 x + 10 − 2 x + 9 = 43

Simplify by adding terms.

Subtract 2 x from 3 x .

x + 10 + 9 = 43

Add 10 and 9 .

x + 19 = 43

Move all terms not containing x to the right side of the equation.

Subtract 19 from both sides of the equation.

x = 43 − 19

Subtract 19 from 43 .

x = 24

Answer: X = 24

Step-by-step explanation:

Move all terms to the left:

(3x + 10) - (2x - 9) - 43 = 0

Get rid of all the parenthesis:

3x + 10 - 2x - 9 - 43 = 0

Add all the numbers and all variable:

x-24 = 0

Move all terms containing x to the left and all other terms to the right:

x = 24

Answer:

The unusual $X$ values for this model are: $X = 0, 1, 2, 7, 8$

Step-by-step explanation:

A binomial random variable $X$ represents the number of successes obtained in a repetition of $n$ Bernoulli-type trials with probability of success $p$ . In this particular case, $n = 8$ , and $p = 0.53$ , therefore, the model is ${8 \choose x} (0.53) ^ {x} (0.47)^{(8-x)}$ . So, you have:
