Answer: in your case, point slope form will be y+1 = (the parellel slope or M)(x-0)

Step-by-step explanation:

basically the point slope form is suppose to be y - (y coodinate) = (M or slope)(x - (x coodinate) )

Parellel lines are the slope is the same, but the coordinates aren't

eg. what is the equation, in point slope form, of the coordinate of a line (3,4) that is parellel to the equation: y = 3/4x + 6

no. 1: slope is 3/4

no. 2 plug all info into the equation: y - (y coodinate) = (M or slope)(x - (x coodinate) )

no.3 you have your equation! y - 4 = 3 / 4 ( x - 3 )

Answer:

B.) y - 6 = -8/5(x + 2)

Step-by-step explanation:

Remember in order to find the slope intercept form on 2 points, you need these equations: $\frac{x_2 -x_1}{y_2 -y_1}$ and $y-y_1=m(x-x_1)$

To find the slope, you will need to use the first equation. In this case the equation will look like this: $\frac{(-2)-6}{3-(-2)}=-\frac{8}{5}$

Then use the second equation, plug in the numbers, and you will get B as your answer

An article presents voltage measurements for a sample of 66 industrial networks in Estonia. Assume the rated voltage for these n

kramer

Answer:

We accept the null hypothesis and conclude that voltage for these networks is 232 V.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 232 V

Sample mean, $\bar{x}$ = 231.5 V

Sample size, n = 66

Sample standard deviation, s = 2.19 V

Alpha, α = 0.05

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 232\\H_A: \mu \neq 232$

We use Two-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n-1}} }$ Putting all the values, we have

$t_{stat} = \displaystyle\frac{231.5- 232}{\frac{2.19}{\sqrt{66}} } = -1.8548$

Now,

$t_{critical} \text{ at 0.05 level of significance, 9 degree of freedom } = \pm 1.9971$

Since,

$|t_{stat}| > |t_{critical}|$

We accept the null hypothesis and conclude that voltage for these networks is 232 V.
