ANSWER ASAP Write an equation of a line that passes through the points (2,3) and (2,-6).

1 answer:

6 0

1st you need to fine the slope using

S = y2-y1/x2-x1

S = -6 - 3/2-2

S = -9/0

S = Undefined

when we have undefined slope the equation would be a vertical lines.

Thus the equation would be the x value of the point

Thus the equation is x = 2

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 450 gram setting. It

Arturiano [62]

Answer:

Test statistic = -2.25

P-value = 0.0199

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 450 gram

Sample mean, $\bar{x}$ = 441 grams

Sample size, n = 16

Alpha, α = 0.05

Sample variance = 256

$\sigma^2 = 256\\\sigma = \sqrt{256} = 16$

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 450\text{ grams}\\H_A: \mu < 450\text{ grams}$

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

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{441 - 450}{\frac{16}{\sqrt{16}} } = -2.25$

Now,

Degree of freedom =

$=n-1 = 16-1=15$

We can calculate the p-value from the table as:

P-value = 0.0199

Conclusion:

Since the p-value is smaller than the significance level we fail to accept the null hypothesis and reject it.

Thus, there is enough evidence to support the claim that the machine is under filling the bags .

A 4-kilogram ham costs $16/kg. Find the cost per pound.

dem82 [27]

1kg is 2.20462 pounds
So 4kgs are 8.81849
Divided by $16 would equal 0.551155625
Therefore Each pound will cost 0.551155625
