Hi there!

• f(x) = \dfrac {7x - 9}{x - 5}

• Then,
To find th' value of f(2). Substitute " 2 " in place of " x "

f(2) = \dfrac {7 × 2 - 9}{2 - 5}

f(2) = \dfrac {14 - 9}{-3}

f(2) = \dfrac {5}{-3}

f(2) = - \dfrac {5}{3}

Hence, f(2) = - \dfrac {5}{3}

~ Hope it helps!

We presume you intend
f(x)=\dfrac{7x-9}{x-5}
and you want to evaluate f(2).

Put 2 where x is, everywhere.
f(2)=\dfrac{7\cdot 2-9}{2-5}=\dfrac{5}{-3}=-\dfrac{5}{3}

A consumer affairs investigator records the repair cost for 4 randomly selected washers. A sample mean of $64.26 and standard de
Mashutka [201]

Answer:

Critical value: z = 1.28

The 80% confidence interval for the mean repair cost for the washers is between $46.487 and $82.033.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.80}{2} = 0.10

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha

So it is z with a pvalue of 1-0.1 = 0.9, so z = 1.28

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

So

M = 1.28*\frac{27.77}{\sqrt{4}} = 17.773

The lower end of the interval is the mean subtracted by M. So 64.26 - 17.773 = $46.487.

The upper end of the interval is M added to the mean. So 64.26 + 17.773 = $82.033.

The 80% confidence interval for the mean repair cost for the washers is between $46.487 and $82.033.

Solve for w<br> 7=-4w+7<br> w=
devlian [24]

Answer:

0

Step-by-step explanation:

If I'm not mistaken, the answer must be 0.

7-7 is 0, that cancels out

0 divided by -4w is zero. That leaves w alone

w=0. I think that's the answer.

4(2p+3)=16<br> solve the equation
Natali5045456 [20]

Final Answer: p = \frac{1}{2}

Steps/Reasons/Explanation:

Question: Solve the equation 4(2p + 3) = 16.

<u>Step 1</u>: Divide both sides by 4.

2p + 3 = \frac{16}{4}

<u>Step 2</u>: Simplify \frac{16}{4} to 4.

2p + 3 = 4

<u>Step 3</u>: Subtract 3 from both sides.

2p = 4 - 3

<u>Step 4</u>: Simplify 4 - 3 to 1.

2p = 1

<u>Step 5</u>: Divide both sides by 2.

p = \frac{1}{2}

~I hope I helped you :)~
