The circumference of a circle is given by the formula C =2πr where r is the measure of the radius?

Mathematics

Answer: 24

Step-by-step explanation:

The perimeter of the length of the rectangle is 24. The perimeter or circumference of the circle can be found using the equation C=2π(r), where r= the radius of the circle. Since we have two semi-circles we can find the circumference of one whole circle with a radius of 4, which would be 8π.

The answer is "above" because the inequality says 2x - 2 > 2 meaning the values must be are greater than that of y = 2.
Its not "intersects" because it would be the equation 2x - 2 = 2

A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than 1
xeze [42]

The test statistic z  is 2.33, the p-value corresponding to the test statistic z value is 0.0099.

<h3>What is Probability?</h3>

Probability is the measure of the likeliness of happening of an event.

The mean of the data is 15.07 centimeters

The standard deviation of the data is 0.26 centimeters.

n = 75

Significance Level ∝ = 0.01

According to the null and alternative hypothesis

Hₐ : \rm \mu ≤15  vs H₁ : \rm \mu >15

The test statistic z  is given by

\rm Z = \dfrac{(X-\mu)}{\sigma/\sqrt{n}}

Z = ( 15.07 -15)/(0.26/√75)

Z = 2.33

The p-value corresponding to z value is 0.0099

as p-value < significance level, therefore the H₁ : \rm \mu >15 is acceptable.

No, significant evidence is not present to tell that the length of bolts is actually greater than the mean value at a significance level of 0.01.

The liabilities of Cullumber are $99,000. Owner’s capital is $143,000; drawings are $96,000; revenues, $467,000; and expenses, $
omeli [17]

Answer:

Total assets = $312000

Step-by-step explanation:

Initial capital of the company = $143000

Drawings = $96000

Revenue = $467000

Expenses = $301000

Now to find the current capital or equity of the company :

Equity = initial capital + Revenue - Drawings - Expenses

          = 143000 + 467000 - 96000 - 301000

          = $213000

Now, liabilities = $99000

And the total assets of the company is given by :

Total Assets = Liabilities + equity of the company

⇒ Total assets = 99000 + 213000

⇒ Total assets = $312000

Hence, Total assets of the Cullumber company = $312000
