6.28318 * 6.3

39.584034

Answer 2

Answer:

see below

Step-by-step explanation:

The perimeter of a circle is called the circumference

C = pi *d

C = pi * 12.6

Using 3.14 as ab approximation for pi

C = 3.14 * 12.6

C =39.564 cm

(IF YOU'RE IN COLLEGE, ANSWER THIS) Should I delete social media?
I have twitter and I feel like it's impacting my life. I'm in college and whenever I study or work on an assignment, I find myself distracted by clicking on the website, and scroll through the timeline for hours. And then boom, it's 8pm. It's the reason why I'm so behind on my studies. I think I should delete it because I care about my future and I wanna become successful (I wanna be a doctor). but at the same time I have like 334 followers lol and it's nice but I should delete it for good I think. People are too toxic and it does no good for my brain.

Answers

Answer:

I think you should delete it because as you said it is distracting you. I think you should just focus on your studies if that is the most important thing to you

imo you should delete social media or at least take a break. it’s really good for both your mental health and for your grades as you’ll be less likely to get distracted or waste time on twitter, instagram, snap... etc. once you’re done with school or caught up with your you can always redownload or log back into your accounts. the people in social media are very toxic and cause pointless drama. since you’re trying to become a doctor i personally believe you should at least limit how often you’re on your phone/on social media or apps that constantly get you distracted. if you think it’ll be hard to put your phone away and focus on your work, use screen time and try to keep you daily usage under 3, 4, 5, 6 whatever hours or so. you can always put a time limit on social media as well

to a whole number. 2 points

Use the personal tax per capita in a sentence explaining what this value means. 4 points

Answers

Answer:

Step-by-step explanation:

a. The personal tax collected for 2019 is $103.0 billion.

  The tax in scientific notation = $1.03 x [tex]10^{11}[/tex]

b. The population in California is 39.50 million people.

The population in scientific notation = 3.95 x [tex]10^{7}[/tex]

c. Assuming that the whole population of people in Califonia are working i.e employed, the the Personal Tax Per Capita can be determined by;

Personal Tax Per Capita = [tex]\frac{income tax revenue}{taxable population}[/tex]

                           = [tex]\frac{103000000000}{39500000}[/tex]

                           = 2607.595

                           = 2.61 x [tex]10^{3}[/tex]

                           = 3.00 x [tex]10^{3}[/tex]

d. Therefore provided that the whole population of people in California for 2019 are employed, then each person pays an average of $2607.595 per annum in the year 2019.

Answer:

x = 5 (check steps below)

Step-by-step explanation:

first off lets combine like terms to make it simple so subtract 7x and 12x which comes out to be -5x and add -45 and 15 on the other side which equals -30 so we end up with

-5x -5 = -30

Now we add 5 onto the other side

-5x = -25

finally we divide by -5 on each side to have x by itself

x = 5

The adjacent supplementary angle to any of the interior angles of a triangle is called an exterior angle of a triangle.

Answers

Answer:

Correct

Step-by-step explanation:

The supplementary angle to any of the interior angles of a triangle is called an exterior angle, they are supplementary because they form a 180º angle when you extend a straight line from the adjacent side of the angle and any straight angle is a 180º angle, so supplementary angles added up would make 180º.

Lee is a teacher at a local high school who wanted to assess whether or not dogs physically resemble their owners enough for people to be able to correctly match a dog to their owner better than if just guessing. Lee, who is also a dog owner, showed pictures of two dogs to her class of 16 students. One photo was of the teacher's dog (Yoda) and the other photo was of a dog the teacher had never met. The students were asked to guess which dog was actually the teacher's. If dogs do not physically resemble their owners, the students would get a correct match with probability 0.50. It turned out that 14 of the 16 students correctly picked out the teacher's dog.
Does it appear that the population proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing?

Answers

Answer:

The  decision rule is  

Reject the null hypothesis  

The conclusion is  

There is sufficient evidence to conclude that the population proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing

Step-by-step explanation:

From the question we are told that

   The sample size is n =  16  

   The population proportion =  0.5

   

     The number that of students that picked out the teachers dog is k  =  14

Generally the sample proportion is mathematically represented as

       [tex]\^ p  =\frac{k}{n}[/tex]

=>     [tex]\^ p  =\frac{14}{16}[/tex]

=>     [tex]\^ p  = 0.875 [/tex]

The null hypothesis is  [tex]H_o :  p = 0.5[/tex]

The null hypothesis is  [tex]H_o :  p >  0.5[/tex]

Generally the test statistics is mathematically represented as

   [tex]z  =  \frac{\^  p  -  p }{\sqrt{ \frac{p(1- p )}{n} }  }[/tex]

    [tex]z  =  \frac{0.875   -  0.50 }{\sqrt{ \frac{0.50 (1- 0.50 )}{16} }  }[/tex]

    [tex]z  = 3[/tex]

Generally the p-value is mathematically represented as

    [tex]p-value  =  P(Z > 3)[/tex]

From the z table the probability of  Z>3  is mathematically represented as

      [tex]P(Z > 3) =  0.0013499[/tex]

So

   [tex]p-value  =  0.0013499 [/tex]

Let  assume the level of significance is  [tex]\alpha = 0. 05[/tex]

Generally from the value  obtained we see that [tex]p-value  <  \alpha[/tex] Hence  

The  decision rule is  

Reject the null hypothesis  

The conclusion is  

There is sufficient evidence to conclude that the population proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing

Contribution Margin, Break-Even Sales, Cost-Volume-Profit Chart, Margin of Safety, and Operating Leverage

Youngsville Industries Inc. expects to maintain the same inventories at the end of 20Y5 as at the beginning of the year. The total of all production costs for the year is therefore assumed to be equal to the cost of goods sold. With this in mind, the various department heads were asked to submit estimates of the costs for their departments during the year. A summary report of these estimates is as follows

It is expected that 22,175 units will be sold at a price of $170 a unit. Maximum sales within the relevant range are 27,500 units.

Answers

Answer:

Giving the following information:

Units sold= 450,000

Total Sales= $12,150,000

Total variable cost= $6,925,500

Total fixed cost= $3,242,673

First, we need to calculate the unitary selling price and variable cost. Then, we calculate the contribution margin.

Selling price= 12,150,000/450,000= $27

Unitary variable cost= 6,925,500/450,000= $15.39

Contribution margin per unit= 27 - 15.39= $11.61

To calculate the contribution margin ratio, we need to use the following formula:

Contribution margin ratio= contribution margin/ selling price

Contribution margin ratio= 11.61/27

Contribution margin ratio= 0.43

To calculate the break-even point both in units and dollars, we need to use the following formulas:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 3,242,673 / 11.61= 279,300 units

Break-even point (dollars)= fixed costs/ contribution margin ratio

Break-even point (dollars)= 3,242,673/0.43= $7,541,100

Finally, we need to incorporate the desired profit to the break-even point formula:

Break-even point in units= (3,242,673 + 426,087) / 11.61

Break-even point in units= 316,000 units
