how many meters of fencing is needed? Round to the nearest whole number? Use 3.14 for .

Answers

Answer 1

Answer:

1571m

Step-by-step explanation:

Step one:

given data

the diameter of the farm= 500m

the radius will be d/2

= 500/2

r=250m

Step two:

Required

The perimeter fence for the farm

this is also the same as the circumference of the farm

C=2πr

C=2*3.142*250

C=1571m

Hence the needed length of fence is 1571m

1. Calculate the federal income taxes. In 2018, the federal income tax was 10 percent on incomes between $0 and $9,525 per year, 12 percent on incomes between
$9,526 and $38,700, and 22 percent on Incomes between $38,701 and $82,500. In 2018, you made $42,000. What was your income tax this year?
O $5,040
$8,400
$4,200
$9,240

Answers

Answer:

$9,240.

Step-by-step explanation:

Given that in 2018, all salaries between $ 38,701 and $ 82,500 had to pay a federal income tax of 22%, and that my salary in that year was $ 42,000, to determine the amount that I had to pay in concept of said tax, the following calculation must be done:

(42,000 x 22) / 100 = X

924,000 / 100 = X

9,240 = X

Therefore, the amount of federal income tax that I had to pay in 2018 was $ 9,240.

What is the triangle?

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

In the diagram, Z is the circumcenter of the triangle TUV. Point Z is the circumcenter of triangle T U V.

As we know, The vertices of a triangle are equidistant from the circumcenter.

VZ = UZ = TZ

UZ = 3x + 4

TZ = 5x

3x + 4 =5x

5x - 3x =4

2x = 4

x = 2

TZ = 5x = 5(2) = 10 units

Thus, the length of Line segment VZ is 10 units if Z is the circumcenter of triangle TUV. Point Z is the circumcenter of triangle T U V option (D) 10 units is correct.

If the cost of a competing factor of production, such as a machine that also could do the job, rises. This would result in a shift in the demand for this factor out to the right and would put pressure on the wage to rise. I don't understand why this is the case because I thought if machines replaced human labor then wouldn't wages be lower because there wouldn't be a need for human labor?

Answers

Keep in mind that we're framing it based on what the first sentence says, which is "If the cost of a competing factor of production, such as a machine that also could do the job, rises".

So if the cost of getting a machine part, various parts, or the entire machine cost rises, then demand for the machine will go down. This will make employers seek out substitutes. In this case, those substitutes would be human labor. As employers demand for labor goes up, the wages will rise assuming the supply of workers is held constant. If the supply of workers increased, then you could argue the wages could go down. So that's why I'm assuming the supply is held in check.

Complete Question

The group of 25 victims scored an average of 25.3 with a sample standard deviation of 9 on the depression scale. The group of 23 bully-victims scored an average of 20.5 with a sample standard deviation of 8 on the same scale. You do not have any presupposed assumptions about whether victims or bully-victims will be more depressed, so you formulate the null and alternative hypotheses as:

[tex]H_o: \ \ \mu_{victims} - \mu_{bully-victims} = 0H1: \ \ \mu _{victims} - \mu_{bully-victims} \ne 0[/tex]

You conduct an independent-measures t test. Given your null and alternative hypotheses,

this is a ________ [ Select ]                       ["two-tailed", "one-tailed"]         test.

The degree of freedom is __________   [ Select ]       ["46", "48", "24", "22"]    

and for an alpha of .01, the critical t is +/-    _________ [ Select ]                       ["2.704", "2.021", "1.684"]    

In order to calculate the t statistic, you first need to calculate the standard error under the assumption that the null hypothesis is true. In order to calculate the standard error, you first need to calculate the pooled variance. The pooled variance is   ________ [ Select ]                       ["72.8696", "145", "0.3756", "71.3201"] .

The standard error is   ___________ [ Select ]             ["2.4664", "2.5572", "1.9543", "72.8712"]         .

The t-statistic is _________ [ Select ]                       ["1.95", "2.55", "-1.70", "-2.25"]

Fourth Question

     The correct option is "72.8696"

Five  Question

     The correct option is "2.4664"

Sixth  Question

     The correct option is "1.95"

Step-by-step explanation:

From the question we are told that

   The number of victims is  [tex]n_1 = 25[/tex]

   The sample mean is  [tex]\= x_1 = 25.3[/tex]

   The standard deviation is  [tex]s_1 = 9[/tex]

   The  number of bully victims is  [tex]n_2 = 23[/tex]

   The sample mean is  [tex]\= x_2 = 20.5[/tex]

    The standard deviation is  [tex]s_2 = 8[/tex]

Generally this is a two -tailed test because  from the null and the alternative hypothesis we see that the test is know whether the mean number of victims is significantly more depressed than bully -victims  or significantly  less depressed than bully -victims

   

Generally the degree of freedom is mathematically represented as  

      [tex]df = n_1 + n_2 -2[/tex]

=>   [tex]df = 25 + 23 -2[/tex]

=>   [tex]df = 46[/tex]

Generally from t distribution table the critical value of  [tex]\alpha = 0.01[/tex] for  a two-tailed test at a degree of freedom of  [tex]df = 46[/tex] is  

      [tex]t_{0.01 , 46} = \pm 2.704[/tex]

Generally the pooled variance is mathematically represented as

     [tex]s^2 = \frac{(n_1 - 1) s_1^2 + (n_2 - 1)s_2^2}{df}[/tex]

=>    [tex]s^2 = \frac{(25 - 1) 9^2 + (23 - 1)8^2}{46}[/tex]

=>    [tex]s^2 = 72.8696[/tex]

Generally the standard error is mathematically represented as

     [tex]SE = s \sqrt{\frac{1}{n_1} + \frac{1}{n_2} }[/tex]

    [tex]SE = \sqrt{s^2} * \sqrt{\frac{1}{n_1} + \frac{1}{n_2} }[/tex]

=>   [tex]SE = \sqrt{72.8696} * \sqrt{\frac{1}{25} + \frac{1}{23} }[/tex]

=>    [tex]SE = 2.4664[/tex]

Generally the  test statistics is mathematically represented as

     [tex]t = \frac{\= x_ 1 - \= x_2}{SE }[/tex]

=>   [tex]t = \frac{25.3 - 20.5}{ 2.4664 }[/tex]

=>   [tex]t =1.95[/tex]

To test if bully-victims are more depressed, we have that:

The null hypothesis is [tex]H_0: \mu_B - \mu_{NB} = 0[/tex]The alternative hypothesis is: [tex]\mu_M - \mu_{NB} < 0[/tex]

For our test, we consider that:

The mean score of bully victims is given by: [tex]\mu_B[/tex].The mean score of non-bully victims is given by: [tex]\mu_{NB}[/tex]

At the null hypothesis, we test that they have the same scores, that is:

[tex]H_0: \mu_B = \mu_{NB}[/tex]

Which can also be written as:

[tex]H_0: \mu_B - \mu_{NB} = 0[/tex]

At the alternative hypothesis, we test if the score of bully victims is less than the score of non-bully victims, that is:

[tex]H_1: \mu_B < \mu_{NB}[/tex]

[tex]H_1: \mu_B - \mu_{NB} < 0[/tex]

Draco invests $5000. Approximately how long will it take for the investment to double if the rate is 10% compounded annually?

Answers

Answer:

I'm in 6th grade and I think it is 500

For the investment to double if the rate is 10% compounded annually,

it will take about 7 years and 3 months.

What is compound interest rate?

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P (1+r/n[tex])^{nt}[/tex]

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for.

Given:

Draco invests $5000.

Draco wants his investment to double.

That means, accrued amount = $10000

Interest rate = 10%

First, convert R as a percent to r as a decimal

r = R/100

r = 10/100

r = 0.1 per year,

Then, by using the formula,

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1/1)] )

t = ln(10,000.00/5,000.00) / ( 1 × [ln(1 + 0.1)] )

t = 7.273 years

t = about 7 years 3 months

Therefore, the required time is about 7 years 3 months.

The population of a particular type of bacteria is known to triple in 22 days. What is the daily growth rate

Answers

Answer: ∛(3)

Step-by-step explanation:

Suppose that at day 0 the population was A.

at day 3, the population will be: 3*A

at day 6, the population will be 3*(3*A) = A*3^2

then, at day N = 3*n (where n = 0, 1, 2.....) the population will be:

P(N) = A*3^n

Particularly, if we take n = 1/3 we will have:

N = 3*1/3 = 1

This means that this is the first day after the day 0.

P(1) = A*3^(1/3)

(then in day one, the population grow by a factor of 3^(1/3))

N = 2 is when n = 2/3, then:

P(2) = A*3^(2/3)

The quotient between P(2) and P(1) is equal to the growth between day one and day two, this should be the same as the growth between day zero and day one.

A*3^(2/3)/(A*3^(1/3)) = 3^( 2/3 - 1/3) = 3^(1/3)

So we found that the daily growth rate is 3^(1/3) or ∛(3)

The daily growth rate of the bacteria is an illustration of unit rates

The daily growth rate of the bacteria is 0.136

For 22 days, the population of the bacteria triples.

The daily rate is the amount of bacteria each day.

So, we have:

[tex]\mathbf{Daily = \frac{Rate}{Days}}[/tex]

This gives

[tex]\mathbf{Daily = \frac{3}{22}}[/tex]

Divide

[tex]\mathbf{Daily = 0.136}[/tex]

Hence, the daily growing rate of the bacteria is 0.136
