pi times [tex]r^{2}[/tex]

Answer:

4π

Step-by-step explanation:

Hello!

The area of a circle is calculated using the formula [tex]A = \pi r^2[/tex].

To solve for the area, we plug in the value for the radius.

Usually we round Pi to 3.14 and multiply, but since it's asking for the exact value, we can just leave it as is.

The area in terms of Pi is 4π.

Answer:

68.3 inches

Step-by-step explanation:

Let the sum of the original 13 students heights be S, so the average of their heights are S/13.

We are given that average height of the original 13 students heights is 68 inches, so S/13 = 68 -> S = 68*13 = 884 inches.

The average of the heights of all 14 students is the sum of all 14 students (S + Danielle’s height) divided by 14. We are given that Danielle’s height is 72.2 inches, so the mean height of all 14 students is:

(S+72.2)/14 = (884+72.2)/14 = 68.3 inches

Answer:

slope = -7/8

y-intercept = 8

Step-by-step explanation:

slope intercept form is

y = mx + b

m is slope

b is y-intercept

------------------------

f(x) = 8 - 7/8x​

Rearrange into slope intercept form

f(x) = -7/8x​ + 8

slope = -7/8

y-intercept = 8

Answer:

Slope = -7/8

Y-intercept = 8

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.

f(x) = 8-7/8x​

Given the above, rearrange it in slope-intercept form to help us find the slope and y-intercept:

f(x) = -7/8x​+8

Now, we can see clearly that -7/8 is in place of m and 8 is in place of b. This means that -7/8 is the slope of the line and 8 is the y-intercept.

I hope this helps!

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean, positive z-scores are above the mean, negative are below the mean and 0 is the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Question a:

Robert, Juan and Linda had positive z-scores, so they scored above the mean, and the correct options are c,d,e.

(b) Which of these students scored on the mean?

Joel, which had a z-score of 0, so the correct option is b.

(c) Which of these students scored below the mean?

Jan and Susan had negative z-scores, so them, options a and f.

Question d:

We have that [tex]\mu = 156, \sigma = 24[/tex], so we have to find X for each student.

Jan:

Z = -0.65. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.65 = \frac{X - 156}{24}[/tex]

[tex]X - 156 = -0.65*24[/tex]

[tex]X = 140[/tex]

b. Joel

Z = 0, so:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0 = \frac{X - 156}{24}[/tex]

[tex]X - 156 = 0*24[/tex]

[tex]X = 156[/tex]

c. Juan

Z = 1.66, so:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.66 = \frac{X - 156}{24}[/tex]

[tex]X - 156 = 1.66*24[/tex]

[tex]X = 196[/tex]

d. Linda

Z = 1.46. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.46 = \frac{X - 156}{24}[/tex]

[tex]X - 156 = 1.46*24[/tex]

[tex]X = 191[/tex]

e. Robert

Z = 1.11. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.11 = \frac{X - 156}{24}[/tex]

[tex]X - 156 = 1.11*24[/tex]

[tex]X = 183[/tex]

f. Susan

Z = -1.9. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.9 = \frac{X - 156}{24}[/tex]

[tex]X - 156 = -1.9*24[/tex]

[tex]X = 110[/tex]

Answer:

a. For Asset 1, we have:

Total cost = $5,864

Total depreciation = $5,264

Annual depreciation = $877.33

b. For Asset 2, we have:

Total cost = $17,210

Total depreciation = $15,310

Annual depreciation = $3,827.50

Step-by-step explanation:

Note: The data in this question are merged together. They are therefore sorted before answering the question. See the attached pdf for the complete question with the sorted data.

Also note: See the attached excel file for the presentation of the data in the question with the answers (in bold red color).

The explanation of the answers is now given as follow:

Straight line method is a method of calculating depreciation and amortization of an asset by dividing the difference between the total cost and salvage value of an asset by its estimated useful life.

Therefore, wee have:

a. For Asset 1, we have:

Total cost = Cost + Shipping Charges + Setup Charge = $5,600 + $210 + $54 = $5,864

Total depreciation = Total cost - Salvage Value = $5,864.00 = $600 = $5,264

Annual depreciation = Total depreciation / Estimated Useful Life = $5,264 / 6 = $877.33

b. For Asset 2, we have:

Total cost = Cost + Shipping Charges + Setup Charge = $16,900 + $310 + $0 = $17,210

Total depreciation = Total cost - Salvage Value = $17,210 - $1,900 = $15,310

Annual depreciation = Total depreciation / Estimated Useful Life = $15,310 / 4 = $3,827.50

Answer:

[tex]circumference = 2\pi \: r \\ = 2 \times \pi \times 22 \\ = 44\pi \: inches[/tex]

Answer:

The circumference is 44 pi.

Step-by-step explanation:

You have to use the formula, C=2 Pi R but since it's in terms of pi, we can not include pi in the equation. 2 times r (radius) is 44, therefor the answer is 44 pi.

Answer:

The graph of g(x) is the graph of f(x) stretched by 3 and shifted 8 units up

Step-by-step explanation:

Given

[tex]f(x)=x^2[/tex]

[tex]g(x) =3x^2 + 8[/tex]

Required

Compare g(x) and f(x)

We have:

[tex]g(x) =3x^2 + 8[/tex]

Rewrite as:

[tex]g(x) =3[x^2] + 8[/tex]

Substitute:[tex]f(x)=x^2[/tex]

[tex]g(x) =3f(x) + 8[/tex]

This means that:

3f(x)

f(x) is stretched vertically by a factor of 3

+8

Then shifted upwards by 8 units to give g(x)

Answer:

last option is correct

Step-by-step explanation:

angle 4 is 128 degree because it is corresponding with angle 3.

Corresponding angles are angles that are in the same position relative to lines intersected by a transversal. When a transversal intersects two lines, the two lines are parallel if and only if corresponding angles are congruent (equal in measure).

Answer:

128 because it is corresponding with 3

Answer:

it is 50.27

Step-by-step explanation:

the formula for finding the area it

A= pi r^2

pi=3.14

so that being said you want to:

you want to divide the diameter by 2 to get 4,then you want to do 4^2 to get 16. then multiply 16 by 3.14 to get 50.265 then you want to round up to 50.27

Answer:

B. 6

Step-by-step explanation:

We can see that through angles A and C that this triangle is an isosceles triangle. Knowing that, we can set up the equation 3x=4x-2. We can simplify by adding 2 two both sides. We get the equation 3x+2=4x. Then we subtract 3x from both sides. So therefore, 2=x. Length AB is 3x so we would do 2*3, which is equal to 6. So your answer would be B. 6.

Answer:

The absolute maximum on the interval 0 < x < 3 is at x = 2 and f(2) = 0. Since x = 2 can only give an absolute maximum, so there is no absolute minimum.

Step-by-step explanation:

f(x) = (-x + 2)⁴

to find the absolute maximum and minimum values, we differentiate f(x) with respect to x.

So df(x)/dx = f'(x) = 4(-x + 2)³

The maximum and minimum values are obtained when f'(x) = 0

So,  4(-x + 2)³ = 0

⇒  (-x + 2)³ = 0

⇒ -x + 2 = 0

-x = -2

x = 2

Now, f(2) = (-2 + 2)⁴ = 0⁴ = 0

So, the absolute maximum on the interval 0 < x < 3 is at x = 2 and f(2) = 0. Since x = 2 can only give an absolute maximum, so there is no absolute minimum.

Answer:

Marmik = 800; Sujata = 600; Kapil = 400

Step-by-step explanation:

Given

Let

[tex]M \to Marmik[/tex]

[tex]S \to Sujata[/tex]

[tex]K \to Kapil[/tex]

Given

[tex]M:S:K = \frac{1}{3}:\frac{1}{4}:\frac{1}{6}[/tex]

[tex]Amount = 1800[/tex]

Required

Divide

We have:

[tex]M:S:K = \frac{1}{3}:\frac{1}{4}:\frac{1}{6}[/tex]

Multiply the ratio by 12 (to convert them to whole numbers)

[tex]M:S:K = 12 *\frac{1}{3}:12*\frac{1}{4}:12*\frac{1}{6}[/tex]

[tex]M:S:K = 4 : 3 : 2[/tex]

The total ratio is:

[tex]Total = 4 + 3 + 2 = 9[/tex]

So, the amount each collected is:

[tex]Marmik = \frac{M}{Total} * Amount[/tex]

[tex]Marmik = \frac{4}{9} *1800 = 800[/tex]

Using the same formula for others, we have:

[tex]Sujata = \frac{3}{9} *1800 = 600[/tex]

[tex]Kapil = \frac{2}{9} *1800 = 400[/tex]

Answer: The events are dependent

The probability is 35/132

==============================================================

Explanation:

If the first bow Sara pulls out isn't put back, then the two events are dependent. This is because the probability of pulling a white bow changes depending on what Sara pulls out.

So again, it all depends on what Sara does because she goes first. This is of course not the case if Sara puts the bow back. If she put it back, then the chances of the teammate pulling the white bow is 7/12

---------

To find the overall probability of Sara selecting a blue bow and not putting it back, followed by a teammate getting a white bow, we multiply the fractions 5/12 and 7/11 to get (5/12)*(7/11) = 35/132
