2-4/5 to the second power

Step-by-step explanation:

To differentiate the function f(x) = 1/x^3, we can use the power rule of differentiation. Here's the step-by-step process:

Write the function: f(x) = 1/x^3.

Apply the power rule: For a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1).

Differentiate the function: In our case, n = -3, so the derivative is:

f'(x) = -3 * x^(-3-1) = -3 * x^(-4) = -3/x^4.

Therefore, the derivative of the function f(x) = 1/x^3 is f'(x) = -3/x^4.

Step-by-step explanation:

To find the equation of a line that is perpendicular to a given line and passes through a specific point, we need to follow a few steps:

Find the slope of the provided line.

The point-slope form of a line is given by: y - y1 = m(x - x1), where (x1, y1) represents the given point.

Substituting the values, the equation of the perpendicular line becomes:

y - 5 = (-1/m)(x - 2)

Simplifying the equation further, we can rewrite it in point-slope form:

y - 5 = (-1/m)x + (2/m)

Answer:

They are asking you to subtrack 9/10 from 1 2/5.

You can achieve this by finding a common denominator for these 2 fractions and then subtracting it.

So, we know that the common denominator is 10 because 5*2=10.

We then change the fraction to 1 4/10.

Then you subtract 9/10 from 1 4/10

1 4/10 can be rewritten as 14/10.

14/10 - 9/10 = 5/10 = 1/2

Let's see what to do buddy....

_________________________________

1) Go...

We have the following equation for finding the slope of the line by using two points :

\(slope = m = \frac{y(b) - y(a)}{x(b) - x(a)} \\ \)

Where a and b are the points which the line through them.

We have points C and D here ,

So :

\(slope = m = \frac{y(d) - y(c)}{x(d) - x(c)} \\ \)

D = ( 7 , 12 ) and C = ( 0 , 0 )

Now just need to put the coordinates in the above equation :

\(slope = m = \frac{12 - 0}{7 - 0} = \frac{12}{7} \\ \)

_________________________________

2) Go...

We have the following equation to find the point-slope form of the linear functions :

\(y - y(o) =(slope) \times ( \: x - x(o) \: ) \\ \)

Where o is one of the given points.

So we must choose one of the points ,

I choose : D = ( 7 , 12 )

Then we have :

\(y - 12 = \frac{12}{7}(x - 7) \\ \)

It's point-slope form, so we need to simplifies it to find slope-intercept form.

Look:

\(y - 12 = \frac{12}{7}x - 12 \\ \)

Both sides plus 12

\(y = \frac{12}{7}x \\ \)

Now we have the slope-intercept form of the CD line.

Step-by-step explanation:

It has the same solution

Anna's total profit was $6000 + $16000 - $4000 = $14000.

How did Anna earn profit

Anna bought $4000 of company stock. The value of the stock doubled when she sold 75% of it, which means she sold 0.75 * $4000 = $3000 worth of stock when its value doubled.

Since the value of the stock doubled, Anna sold the $3000 worth of stock for 2 * $3000 = $6000.

Anna then sold the remainder of the stock (25% of the original amount) for four times the purchase price. Since she originally bought the stock for $4000, the remainder was worth 0.25 * $4000 = $1000.

Selling this remainder for four times the purchase price means that Anna sold it for 4 * $4000 = $16000.

Step-by-step explanation:

The relationship between the quantities shown in the table is +10. The values in column 2 (y) are obtained by adding 10 to the corresponding values in column 1 (x).

In the given table, the values in column 1 (labeled "x") are 1, 2, 3, and 4. The values in column 2 (labeled "y") are 11, 22, 33, and 44.

To determine the relationship between the quantities in the table, we can compare the values in column 2 (y) with the corresponding values in column 1 (x).

If we subtract each value in column 1 from the corresponding value in column 2, we find that:

11 - 1 = 10

22 - 2 = 20

33 - 3 = 30

44 - 4 = 40

By observing these results, we can see that the difference between each value in column 2 and its corresponding value in column 1 is always 10.

Answer:

a) In the step-by-step explanation.

b)  The null and alternative hypothesis are:

\(H_0: \mu=125000\\\\H_a:\mu> 125000\)

c) P-value = 0.015

d) The conclusion, at a level of significance of 0.05, is that there is enough evidence to support the claim that that area residential property is available at a mean cost significantly higher than $125,000 per lot.

e) The claim of the chamber of commerce is false. We have statistical evidence against that claim and we can conclude that the mean prices are significantly higher than $125,000.

Step-by-step explanation:

This is a hypothesis test for the population mean.

The claim, expressed in the alternative hypothesis, is that area residential property is available at a mean cost significantly higher than $125,000 per lot.

Then, the null and alternative hypothesis are:

\(H_0: \mu=125000\\\\H_a:\mu> 125000\)

The significance level is 0.05.

The sample has a size n=32.

The sample mean is M=130000.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=12500.

The estimated standard error of the mean is computed using the formula:

\(s_M=\dfrac{s}{\sqrt{n}}=\dfrac{12500}{\sqrt{32}}=2209.71\)

Then, we can calculate the t-statistic as:

\(t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{130000-125000}{2209.71}=\dfrac{5000}{2209.71}=2.26\)

The degrees of freedom for this sample size are:

\(df=n-1=32-1=31\)

This test is a right-tailed test, with 31 degrees of freedom and t=2.26, so the P-value for this test is calculated as (using a t-table):

\(\text{P-value}=P(t>2.26)=0.015\)

As the P-value (0.015) is smaller than the significance level (0.05), the effect is  significant.

The null hypothesis is rejected.

There is enough evidence to support the claim that that area residential property is available at a mean cost significantly higher than $125,000 per lot.

The percentage increase from Day 2 to Day 3 of the birds is =20%

Answer:

150 degrees

Step-by-step explanation:

Hi,

Since one of the angles is 30 degrees and this is a line, we know that 30 + u must equal 180 degrees.

30 + u = 180

Subtract 30 from 180 to find the value of u.

u is 150 degrees.

I hope this helps :)

Answer: 150 degrees

Step-by-step explanation:

A line is 180 degrees in total, since that acute angle is 30 degrees you just subtract 30 from 180, which gives you the other side ( which has to equal 180) of 150 degrees. If it were 40 degrees ( instead of 30) it would be 140 degrees on the other side.... etc

Answer:

-14.4444°C

Step-by-step explanation:

(6°F − 32) × 5/9 = -14.44°C

Answer:

38 plain chocolate bars and 17 king-size chocolate bars.

Step-by-step explanation:

Let's define the variables:

P = number of plain chocolate bars sold

K = number of king chocolate bars sold

We know that each plain one costs $1.50, and each king one costs $2.25, then the total revenue is:

P*$1.50 + K*$2.25

Now we know that Jim sells a total of 55 candy bars, then:

P + K = 55

And we know that the total revenue is $95.25, then:

P*$1.50 + K*$2.25 = $95.25

Then we have the system of equations:

P + K = 55

P*$1.50 + K*$2.25 = $95.25

To solve this we need to isolate one of the variables in one of the equations, I will isolate P in the first equation to get:

P = 55 - K

Now we can replace is on the second one to get:

(55 - K)*$1.50 + K*$2.25 = $95.25

Now we can solve this for K

$82.50 - K*$1.50 + K*$2.25 = $95.25

K*($2.25 - $1.50) = $95.25 - $82.50 = $12.75

K*$0.75 = $12.75

K = $12.75/$0.75 = 17

This means that Jim sold 17 king-size chocolate bars.

Now we can replace this in the equation:

P + K = 55

P + 17 = 55

P = 55 - 17  =38

P = 38

Jim sold 38 plain chocolate bars.

Answer:

9.375

Step-by-step explanation:

With  the empirical rule, we can estimate that the number of farms in the sample whose land and building values per acre are between $1100 and $1500 is approximately 50 farms.

The empirical rule (also known as the 68-95-99.7 rule) states that for data sets with a bell-shaped distribution:

68% of the data falls within one standard deviation of the mean.

95% of the data falls within two standard deviations of the mean.

99.7% of the data falls within three standard deviations of the mean.

Using this rule, we can estimate the number of farms whose land and building values per acre are between $1100 and $1500 as follows:

The mean value of land and buildings per acre from the sample of farms is $1300, and the standard deviation is $200.

$1100 is 1.5 standard deviations below the mean:

($1100 - $1300) / $200 = -1.0.

$1500 is 1 standard deviation above the mean:

($1500 - $1300) / $200 = 1.0.

Therefore, we can estimate that approximately:

68% of the farms in the sample have land and building values per acre between $1100 and $1500 plus or minus one standard deviation of $200. This is equivalent to approximately 50 farms, which is 68% of the sample size of 74 farms.

95% of the farms in the sample have land and building values per acre between $900 and $1700 plus or minus two standard deviations of $200. This is equivalent to approximately 70 farms, which is 95% of the sample size of 74 farms.

99.7% of the farms in the sample have land and building values per acre between $700 and $1900 plus or minus three standard deviations of $200. This is equivalent to approximately 73 farms, which is almost the entire sample size of 74 farms.

Probabilities are used to determine the chances of events.

The given parameters:

\(n = 5\) ---- the number of candy bars

\(p = 40\%\) ---- the probability of selling a candy bar

(a) Name distributions

The distribution of X is represented as:

\(X \sim(r,p)\)

Where:

\(r = 5\)

\(p= \frac{5\times 40\%}{10}\)

\(p= 0.2\)

So, the name distribution of X is \(X \sim(r= 5,p = 0.2)\)

(b) The probability that the last candy is sold at the 11th house

This means that:

\(n = 10\) --- the number of previous houses

\(r = 4\) --- the previous number of candies

\(p = 0.4\) --- the given probability of selling a candy

The probability is calculated using:

\(P(x = n+1) = ^{n}C_r \times p^{r +1} \times (1 - p)^{n-r}\)

This gives

\(P(x = 10+1) = ^{10}C_4 \times 0.4^{4 +1} \times (1 - 0.4)^{10-4}\)

\(P(x = 11) = ^{10}C_4 \times 0.4^{5} \times (0.6)^6\)

\(P(x = 11) = 210 \times 0.4^5 \times 0.6^6\)

\(P(x = 11) = 0.1003290624\)

Approximate

\(P(x = 11) = 0.1003\)

Hence, the probability that the last candy is sold at the 11th house is 0.1003

(b) The probability he sells the candies on or before the 8th house

The probability is calculated using:

\(P(x \le 8) = P(5 \le x \le 8)\)

This gives

\(P(x \le 8) = ^{10}C_5 \times 0.4^{6} \times (0.6)^5 + ^{10}C_6 \times 0.4^{7} \times (0.6)^4 + ^{10}C_7 \times 0.4^{8} \times (0.6)^3 +^{10}C_8 \times 0.4^{9} \times (0.6)^2\)

\(P(x = 11) = 0.1737\) ---- approximated

Hence, the probability he sells the candies on or before the 8th house is 0.1737
