Use the definition of the derivative to differentiate f(x)= In x

Answers

By def. of the derivative, we have for y = ln(x),

[tex]\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac{\ln(x+h)-\ln(x)}{h}[/tex]

[tex]\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac1h \ln\left(\frac{x+h}{x}\right)[/tex]

[tex]\displaystyle \frac{dy}{dx} = \lim_{h\to0} \ln\left(1+\frac hx\right)^{\frac1h}[/tex]

Substitute y = h/x, so that as h approaches 0, so does y. We then rewrite the limit as

[tex]\displaystyle \frac{dy}{dx} = \lim_{y\to0} \ln\left(1+y\right)^{\frac1{xy}}[/tex]

[tex]\displaystyle \frac{dy}{dx} = \frac1x \lim_{y\to0} \ln\left(1+y\right)^{\frac1y}[/tex]

Recall that the constant e is defined by the limit,

[tex]\displaystyle e = \lim_{y\to0} \left(1+y\right)^{\frac1y}[/tex]

Then in our limit, we end up with

[tex]\displaystyle \frac{dy}{dx} = \frac1x \ln(e) = \boxed{\frac1x}[/tex]

Find the expected value of the amount of time Kelsie spends filling out daily sales reports.

Answers

According to the discrete distribution given, it is found that the expected value of the amount of time Kelsie spends filling out daily sales reports is of 9.5 minutes.

The discrete distribution given is:

[tex]P(X = 0) = 0.3[/tex]

[tex]P(X = 10) = 0.5[/tex]

[tex]P(X = 20) = 0.15[/tex]

[tex]P(X = 30) = 0.05[/tex]

The mean of a discrete distribution is the sum of each outcome multiplied by it's respective probability, hence:

[tex]E(X) = 0(0.3) + 10(0.5) + 20(0.15) + 30(0.05) = 9.5[/tex]

The expected value of the amount of time Kelsie spends filling out daily sales reports is of 9.5 minutes.

Answer:

Step-by-step explanation:

textRequest reports that adults 18–24 years old send and receive 128 texts every day. Suppose we take a sample of 25–34 year olds to see if their mean number of daily texts differs from the mean for 18–24 year olds reported by TextRequest.a. State the null and alternative hypotheses we should use to test whether the popu-lation mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds.b. Suppose a sample of thirty 25–34 year olds showed a sample mean of 118.6 texts per day. Assume a population standard deviation of 33.17 texts per day and com-pute the p-value.c. With a = .05 as the level of significance, what is your conclusion? d. Repeat the preceding hypothesis test using the critical value approach.d. Repeat the preceding hypothesis test using the critical value approach.

Answers

Testing the hypothesis, we have that:

a)

The null hypothesis is: [tex]H_0: \mu = 128[/tex]

The alternative hypothesis is: [tex]H_1: \mu \neq 128[/tex]

b) The p-value of the test is of 0.1212.

c) Since the p-value of the test is of 0.1212 > 0.05, we cannot conclude that the mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds.

d) Since |z| = 1.55 < 1.96, we cannot conclude that the mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds.

Item a:

At the null hypothesis, we test if the mean is the same, that is, of 128 texts every day, hence:

[tex]H_0: \mu = 128[/tex]

At the alternative hypothesis, we test if the mean is different, that is, different of 128 texts every day, hence:

[tex]H_1: \mu \neq 128[/tex]

Item b:

We have the standard deviation for the population, thus, the z-distribution is used. The test statistic is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

The parameters are:

[tex]\overline{x}[/tex] is the sample mean.

[tex]\mu[/tex] is the value tested at the null hypothesis.

[tex]\sigma[/tex] is the standard deviation of the population.

n is the sample size.

For this problem, the values of the parameters are: [tex]\overline{x} = 118.6, \mu = 128, \sigma = 33.17, n = 30[/tex]

Hence, the value of the test statistic is:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{118.6 - 128}{\frac{33.17}{\sqrt{30}}}[/tex]

[tex]z = -1.55[/tex]

Since we have a two-tailed test, as we are testing if the mean is different of a value, the p-value is P(|z| < 1.55), which is 2 multiplied by the p-value of z = -1.55.

Looking at the z-table, z = -1.55 has a p-value of 0.0606

2(0.0606) = 0.1212

The p-value of the test is of 0.1212.

Item c:

Since the p-value of the test is of 0.1212 > 0.05, we cannot conclude that the mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds.

Item d:

Using a z-distribution calculator, the critical value for a two-tailed test with 95% confidence level is |z| = 1.96.

Since |z| = 1.55 < 1.96, we cannot conclude that the mean daily number of texts for 25–34 year olds differs from the population daily mean number of texts for 18–24 year olds.

Clarice Sloan is a shift supervisor for Ace
Tomato Inc. She is paid monthly with FIT
deductions of $102, SIT of 3.2% of gross,
and CIT of 1.8% of gross. Her monthly
net pay is $3,804.33. What is her monthly
gross pay?

Answers

The net pay is the amount left after taxes and deductions have been removed from the gross pay.

Her monthly gross pay is: $4111.93

The deductions are:

[tex]\mathbf{FIT = \$102}[/tex]

[tex]\mathbf{SIT = 3.2\%}[/tex]

[tex]\mathbf{CIT = 1.8\%}[/tex]

Let her gross pay be x.

So, we have:

[tex]\mathbf{Net = x - FIT - x \times SIT - x \times CIT}[/tex]

So, we have:

[tex]\mathbf{3804.33 = x - 102 - x \times 3.2\%- x \times 1.8\%}[/tex]

Express percentage as decimals

[tex]\mathbf{3804.33 = x - 102 - x \times 0.032- x \times 0.018}[/tex]

[tex]\mathbf{3804.33 = x - 102 - 0.032x - 0.018x}[/tex]

Add 102 to both sides

[tex]\mathbf{3906.33 = x - 0.032x - 0.018x}[/tex]

[tex]\mathbf{3906.33 = 0.95x}[/tex]

Divide both sides by 0.95

[tex]\mathbf{4111.93 = x}[/tex]

Rewrite as:

[tex]\mathbf{x = 4111.93 }[/tex]

Hence, her monthly gross pay is: $4111.93
