Answer:

The answer is A

Step-by-step explanation:

A proportional function is a function where the output = constant x input

Let's make each of these situations into an equation

A) y = 3.5x

B) y = 40x + 25

C) y = 2x + 56

D) y = 2x + 5

because A is the only one that follows the output = constant x input rule it is the example of a proportional function

Find the t-value such that the area in the right tail is 0.005 with 28 degrees of freedom.

klasskru [66]

Answer:

$t = 3.673900$

Step-by-step explanation:

Given

$df = 28$ -- degree of freedom

$Area = 0.005$

Required

Determine the t-value

The given parameters can be illustrated as follows:

$P(T > t) = \alpha$

Where

$\alpha = 0.005$

So, we have:

$P(T>t) = 0.005$

To solve further, we make use of the attached the student's t distribution table.

From the attached table,

The t-value is given at the row with df = 28 and $\alpha = 0.005$ is 3.673900

Hence, $t = 3.673900$

Answer:

$\frac{4}{3}$

Step-by-step explanation:

<u>Step 1: Divide</u>

<u /> $\frac{8}{9} / \frac{2}{3}$

$\frac{8}{9} * \frac{3}{2}$

$\frac{8 * 3}{9 * 2}$

$\frac{24/6}{18/6}$

$\frac{4}{3}$

Answer: $\frac{4}{3}$
