The point-slope form equation for this line is y₁ - 9 = 4 (x₁ - 1), or D.

Since these are all in point-slope form, all we need to do is find the slope and then input one value of (x, y) into the points. We start with the slope.

m = $\frac{y₁ - y}{x₁ - x}$

m = $\frac{3 - 9}{-2 -1}$

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

m = 2

Now we need to input the values of one of the points and slope into the point slope equation: y₁ - y = m(x₁ - x).

Inputting (1, 9), we get

y₁ - 9 = 4 (x₁ - 1)

The equation that fits it is D., so that means that the only answer to this question is D.

The best batch size is 1053.

Since 5% have failed, this means 95% have passed the test.

95% = 95/100 = 0.95

We can set up an equation to answer this:
0.95x = 1000

Divide both sides by 0.95:
0.95x/0.95 = 1000/0.95
x = 1052.6 ≈ 1053

The dimensions of a conical funnel are shown below: A conical funnel is shown with the height of the cone as 7 inches and the ra

Nataly [62]

The first thing we should know in this case is that by definition the flow of liquid is given by:
Q = V / t
Where,
V: volume
t: time
The volume of the cone is given by:
V = (pi * r ^ 2 * h) / (3)
Where,
r: radio
h: height
Substituting the values we have:
V = (3.14 * ((3) ^ 2) * 7) / (3)
V = 65.94 in ^ 3
We now turn off the time of the flow equation:
t = V / Q
Substituting values:
t = (65.94) / (14)
t = 4.71 minutes
Answer:
It will take for all the liquid in the funnel to pass through the nozzle about:
t = 4.71 minutes

The owners of an industrial plant want to determine which of two types of fuel (gas or electricity) will produce more useful ene

madreJ [45]

Answer:

d. H0: $(\mu_e - \mu_g) = 0$ vs. $Ha: (\mu_e - \mu_g) \neq 0$

Step-by-step explanation:

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

On this case the Management try to determine if there is a difference in the average investment/quad between using electricity and using gas. So this needs to be on the alternative hypothesis. And the complement of the alternative hypothesis would be on the null hypothesis.

Null hypothesis : $\mu_e = \mu_g$

Alternative hypothesis: $\mu_e \neq \mu_g$

Or equivalently:

Null hypothesis : $\mu_e - \mu_g = 0$

Alternative hypothesis: $\mu_e - \mu_g \neq 0$

Other important thing is that on the alternative hypothesis we never can have the symbol equal.

So on this case the best options is:

d. H0: $(\mu_e - \mu_g) = 0$ vs. $Ha: (\mu_e - \mu_g) \neq 0$
