Linear function for f(-11)=5, slope of f= -2/3

wolverine [178]

Answer:

f(x) = -2/3(x +11) +5

Step-by-step explanation:

The point-slope form of the equation of a line will give you the desired linear function:

y = m(x -h) +k . . . . . for slope m through point (h, k)

You are give point (x, f(x)) = (-11, 5) = (h, k), and you are given slope m = -2/3. Putting these values into the function form gives ...

f(x) = -2/3(x +11) +5

Given A(8,3), B(4,8), C(4,4) and D(8,-1) find the slope of AB

Snezhnost [94]

Answer:

Step-by-step explanation:

Slope: $\frac{y_2-y_1}{x_2-x_1}$ when the given points are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in A(8,3) and B(4,8)

$=\frac{8-3}{4-8} \\=\frac{5}{-4}\\=-\frac{5}{4}$

Therefore, the slope of AB is $-\frac{5}{4}$ .

I hope this helps!

In an effort to improve scores on college-entrance exams, the principal at a large high school chooses 35 students

denpristay [2]

Using the t-distribution, it is found that the test statistic for the hypotheses test is given by:

$t = \frac{-1.75 - 0}{\frac{7.12}{\sqrt{35}}}$

<h3>What are the hypotheses tested?</h3>

At the null hypotheses, it i tested if the mean difference remains the same, that is:

$H_0: \mu = 0$

At the alternative hypotheses, it is tested if it has decreased, hence:

$H_a: \mu < 0$ .

<h3>What is the test statistic?</h3>

The test statistic is given by:

$t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}$

The parameters are:

$\overline{x}$ is the sample mean.

$\mu$ is the value tested at the null hypothesis.

s is the standard deviation of the sample.

n is the sample size.

The parameters are given as follows:

$\overline{x} = -1.75, s = 7.12, n = 35$ .

Hence the test statistic is given by:

$t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}$

$t = \frac{-1.75 - 0}{\frac{7.12}{\sqrt{35}}}$
