Answer: The slope is −2/3

Step-by-step explanation:

2 x + 3 y = 12 is the standard form for a linear equation. To determine the slope, solve the equation for y in order to convert to the slope-intercept form y = m x + b , where m is the slope and b is the y-intercept.

2 x + 3 y = 12

Subtract 2 x from both sides.

3 y = − 2 x + 12

Divide both sides by

3 . y = − 2 /3 x + 12 /3 =

y = − 2 /3 x + 4

The slope is

− 2 /3

Answer:

8 and 2.529

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

Given that

Total number of questions is n = 40

The Probability of correct answer is p = $\frac{1}{5}$

So, the probability of the wrong answer is q = $1 - \frac {1}{5}$ = $\frac{4}{5}$

Moreover, this is the binomial distribution

Based on the above information

The mean is

$= n \times p$

$= 40\times \frac{1}{5}$

= 8

Now the variance is

$= 40\times \frac{1}{5} \times \frac{4}{5}$

= $\frac{32}{5}$

So, the standard deviation is

$= \sqrt{\frac{32}{5} }$

= 2.529

hence, the mean and the standard deviation is 8 and 2.529 respectively
