Answer:

If $17x-1=2\\$ , then $2(x)^2\\$ will equal $\frac{18}{289}$

If $x-1=2$ , then $2(x)^2\\$ will equal $2\\$

Step-by-step explanation:

For the step-by-step solution, please see the attachment. Part A, $17x-1=2\\$ and $x-1=2$ , is executed in black ink while Part B, $2(x)^2\\$ , is executed in blue ink. Detailed justification of each step in green. The given function is provided in red ink.

Answer:

Step-by-step explanation:

Given

x - 1 = 2 ( add 1 to both sides )

x = 3

Then

2x² = 2(3)² = 2 × 9 = 18

You design a new app for cell phones. Your revenue for x downloads is given by f(x) = 3x Your profit

Snowcat [4.5K]

Answer:

p = 2.7x - 20

p(90) = $223

Step-by-step explanation:

revenue → f(x) = 3x ,where x is the number of downloads.

the statement “Your profit p is $20 less than 90% of the revenue for x downloads”

<u><em>means</em></u>

$p=90\% f\left( x\right) -20$

<u><em>means</em></u>

<u><em></em></u> $p=\frac{90}{100} \times f\left( x\right) -20$

<u><em>means</em></u>

$p=\frac{9}{10} \times (3x) -20$

<u><em>means</em></u>

$p=\frac{9}{10} \times (3x) -20$

<u><em>means</em></u>

$p=2.7x -20$

………………………………

the profit for 90 downloads :

= p(90)

= 2.7×(90) - 20

= $223

A friend of yours was interested in determining whether the news media noticed campus events. Your friend decided to do a conten

anygoal [31]

The inference is that the person will tell the friend that he did manifest coding and he should have recorded the base.

<h3>What is an inference?</h3>

The options are:

He did manifest coding.

He did latent coding.

He should have recorded the base.

He did manifest coding and he should have recorded the base.

It should be noted that an inference simply means the conclusion that can be deduced based on the information given.

In this case, the friend was interested in determining whether the news media noticed campus events and decided to do a content analysis of the local paper.

Therefore, the the person will tell the friend that he did manifest coding and he should have recorded the base.

One terameter equals 1012 meters. One micrometer equals 10 meter.

Butoxors [25]

Answer:

<h2>a) 10⁶metres</h2><h2>b) 10¹⁸metres</h2>

Step-by-step explanation:

Given One terameter equals 10¹² meters. One micrometer equals 10⁻⁶ meter, one nanometer equals 10⁻⁹meter;

a) The product of one terameter and one micrometer will be expressed as;

10¹² * 10⁻⁶

Since the both have the same base, we will add their power according to one of the law in indices as shown

10¹² * 10⁻⁶ = 10⁻⁶⁺¹²

= 10⁶metres

b) The quotient of one terameter and one micrometer can be gotten by taking their ratio as shown below;

Note that when taking the quotient, the power are subtracted

$= \frac{10^{12} }{10^{-6} } \\= 10^{12-(-6)} \\= 10^{12+6} \\= 10^{18}metres$

A one-tailed test is a a. hypothesis test in which rejection region is in one tail of the sampling distribution b. hypothesis te

garri49 [273]

Answer:

Option A) One tailed test is a hypothesis test in which rejection region is in one tail of the sampling distribution

Step-by-step explanation:

One Tailed Test:

A one tailed test is a test that have hypothesis of the form

$H_0: \bar{x} = \mu\\H_A: \bar{x} < \mu\text{ or } \bar{x} > \mu$

A one-tailed test is a hypothesis test that help us to test whether the sample mean would be higher or lower than the population mean.
Rejection region is the area for which the null hypothesis is rejected.
If we perform right tailed hypothesis that is the upper tail hypothesis then the rejection region lies in the right tail after the critical value.

If we perform left tailed hypothesis that is the lower tail hypothesis then the rejection region lies in the left tail after the critical value.

Thus, for one tailed test,

Option A) One tailed test is a hypothesis test in which rejection region is in one tail of the sampling distribution
