Answer:

y = -2x + 1

Step-by-step explanation:

To find slope, you need to use the formula:

m = $\frac{y_{2}- y_{1} }{x_{2} -x_{1} }$

Plug in the numbers accordingly:

m = $\frac{-3-3 = -6}{2 +1 = 3}$

m = $\frac{-6}{3}$

Simplify:

m = -2

To find the y-intercept, you need to plug in one of the coordinates (doesn't matter which one) into the equation:

Coordinate : (-1, 3)

3 = -2(-1) + b

3 = 2 + b

Subtract 2 from both sides:

3 = 2 + b

-2 -2

________

1 = b

Put it all together:

y = -2x + 1

360 degrees is a full turn, so if you multiply 30 degreed by 12, you go around in a circle.

The per capita electric power consumption level in a recent year in Ecuador is normally distributed, with a mean of 471.5 kilo-w

Olin [163]

Answer:

a) 471.5 kilo-watt hours.

b) 31.76 kilo-watt hours

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
