Find the vertex of the graph

Help me plzzzz I really need your help

Shkiper50 [21]

Point D would be (0, 0).And to graph it, you would just find the points o the graph using the x and y axis.

What is the slope of the line that passes through the points (-1,-7) and (1, -13)? Write your answer in simplest form.

mestny [16]

Answer:

Slope = 0

Explanation:

m= (−7) − (−7) / (−13) − (−1) = 0

(x1,y1)=(−1,−7) and (x2,y2)=(−13,−7). Since y1=y2 therefore this line is parallel to x-axis. Hence slope is zero.

In a sentence.

Allisa [31]

Answer:

Kelsey can buy 9 books.

Step-by-step explanation:

If Kelsey wants to buy as much books as possible with 30$, multiply 3$ by 9 (books) which is 27$.

30$-27$ is 3$ so she will have 3$ extra dollars to use for shipping. 2$ is the price for shipping so she will have an extra dollar.

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 430 gram setting. It is

Volgvan

Answer:

Null Hypothesis, $H_0$ : $\mu$ $\geq$ 430 gram {means that the machine is not under filling the bags}

Alternate Hypothesis, $H_A$ : $\mu$ < 430 gram {means that the machine is under filling the bags}

Step-by-step explanation:

We are given that a manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 430 gram setting.

It is believed that the machine is under filling the bags. A 21 bag sample had a mean of 429 grams with a variance of 289.

Let $\mu$ = mean weight bag filling capacity of machine.

SO, Null Hypothesis, $H_0$ : $\mu$ $\geq$ 430 gram {means that the machine is not under filling the bags}

Alternate Hypothesis, $H_A$ : $\mu$ < 430 gram {means that the machine is under filling the bags}

The test statistics that will be used here is One-sample t test statistics as we don't know about the population standard deviation;

T.S. = $\frac{\bar X -\mu}{\frac{s}{\sqrt{n} } }$ ~ $t_n_-_1$

where, $\bar X$ = sample mean = 429 grams

s = sample standard deviation = $\sqrt{289}$ = 17 grams

n = sample of bags = 21

So, test statistics = $\frac{429-430}{\frac{17}{\sqrt{21} } }$ ~ $t_2_0$

= -0.269

Now at 0.01 significance level, the t table gives critical value of -2.528 at 20 degree of freedom for left-tailed test. Since our test statistics is higher than the critical value of t as -0.269 > -2.528, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.

Therefore, we conclude that the machine is not under filling the bags.

Find the domain and the range of the relation shown on the

irinina [24]

The domain of a graph is the possible values of x, the graph can take.

(b) The domain of the relation is the interval [-10,10]

From the attached graph, we have the following observations on the x-axis.

The value of x starts from -10
The value of x ends at 10

So, the domain of x is from -10 to 10

Using interval notation, the domain of the relation is: $[-10,10]$
