Answers

Answer:

x = 16/15

Step-by-step explanation:

Given:

6 - 3/4x + 1/3 = 1/2x + 5

Collect like terms

6 + 1/3 - 5 = 1/2x + 3/4x

(18+1-15)/3 = (2x+3x)/4

4/3 = 5/4x

x = 4/3 ÷ 5/4

x = 4/3 × 4/5

x = (4 * 4) / (3 * 5)

x = 16/15

In diffuse reflection, reflected rays move in different directions. In scattering, long wavelengths are scattered the most.

Answers

Answer:

D. In scattering, long wavelengths are scattered the most.

Step-by-step explanation:

Scattering of light is the effect observed when there is an interaction between light energy and some particles. This occurs often in the earth's atmosphere which consists of different sizes of particles that interacts with the sunlight.

In scattering, light of shorter wavelengths are scattered by small sized particles compared to those with longer wavelengths. Example is the scattering of the sunlight by the atmospheric particles where colors with short wavelengths are scattered the most.

Arnold need to correct the statement; In scattering, long wavelengths are scattered the most. To read; In scattering, short wavelengths are scattered the most.

what is the surface area of a sphere if the volume is 3000 pi

Answers

Answer:

228.95 cm2 / 229 cm2

Step-by-step explanation:

Volume of a sphere is given by;

V = (4/3)πr3

So in this question we have to find the radius of the sphere to enable us find the surface area.

Therefore let's find the radius using the volume formula;

3000π = (4/3)πr3

Divide through by (4/3)π

r3 = 2250

r =3√2250 (cube root of 2250)

r = 13.104cm2

Since we have gotten the radius, let's calculate the surface area using the formula;

A = (4/3)πr^2

= (4/3) × π × 13.104^2

= 228.95 π cm2 or 229 cm2

2. In your own words, explain HOW to find the standard deviation of this data set. (20 points) 3. What does the standard deviation tell you about this data? (20 points) I NEEDDDDD THISSSSSS PLSSSSSSSSSSSSSSSS

Answers

Answer:

[tex]\sigma = 11.28[/tex] --- Standard deviation

Step-by-step explanation:

Given

See attachment for graph

Solving (a): Explain how the standard deviation is calculated.

Start by calculating the mean

To do this, we divide the sum of the products of grade and number of students by the total number of students;

i.e.

[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]

So, we have:

[tex]\bar x = \frac{50 * 1 + 57 * 2 + 60 * 4 + 65 * 3 +72 *3 + 75 * 12 + 77 * 10 + 81 * 6 + 83 * 6 + 88 * 9 + 90 * 12 + 92 * 12 +95 * 2 + 99 * 4 + 100 * 5}{1 + 2 + 4 + 3 +3 + 12 + 10 + 6 + 6 + 9 + 12 + 12 +2 + 4 + 5}[/tex]

[tex]\bar x = \frac{7531}{91}[/tex]

[tex]\bar x = 82.76[/tex]

Next, calculate the variance using the following formula:

[tex]\sigma^2 = \frac{\sum f(x - \bar x)^2}{\sum f}[/tex]

i.e subtract the mean from each dataset; take the squares; add up the squares; then divide the sum by the number of dataset

So, we have:

[tex]\sigma^2 = \frac{1 * (50 - 82.76)^2 +...................+ 5 * (100 - 82.76)^2}{91}[/tex]

[tex]\sigma^2 = \frac{11580.6816}{91}[/tex]

[tex]\sigma^2 = 127.26[/tex]

Lastly, take the square root of the variance to get the standard deviation

[tex]\sigma = \sqrt{\sigma^2}[/tex]

[tex]\sigma = \sqrt{127.26}[/tex]

[tex]\sigma = 11.28[/tex] --- approximated

Hence, the standard deviation is approximately 11.28

Considering the calculated mean (i.e. 82.76), the standard deviation (i.e. 11.28) is small and this means that the grade of the students are close to the average grade.

Answers

Respuesta:

156,46 m

Explicación paso a paso:

Podemos obtener la altura de la torre de enfriamiento usando trigonometría;

Tan θ = opuesto / adyacente

Altura de la torre de enfriamiento = opuesto

Altura de la sombra = 271 m = adyacente

Tan 30 = opuesto / 271

Opuesto = 271 tan30

Altura de la torre de enfriamiento = 0.5773502 * 271

Which of the following is the solution to the equation x + 8.6 = 36.2?
10.4
17.2
27.6
44.8

Answers

Answer:

27.6

Step-by-step explanation:

x+8.6=36.2

Subtract 8.6 from both sides.

x=36.2-8.6

Subtract 8.6 from 36.2 to get 27.6.

x=27.6

The letter is c so 27.6

x+8.6=36.2 ( original problem)

Subtract 8.6 from both sides

Then you get x=27.6

Answers

Answer:

Step-by-step explanation:

3. Crystal has decided to drive her new car on the west coast from California to Washington, which is about 930
miles. She plans to drive her car an equal number of miles per day.
The number of days it will take her to get to Washington can be represented as a function of the distance
traveled per day. This function can be represented by the function (d) where W(d) is the number of
days it will take to get to Washington, and d is the distance traveled per day measured in miles per day.
=930/d
Select Yes or No to indicate whether the graph represents the number of days it will take Crystal to get to
Washington in her car, as a function of the distance traveled per day.

Answers

Answer:

The correct option is the first graph (Yes)

Step-by-step explanation:

The given function is W(d) = 930/d

Where;

W(d) = The number of days it would take to get to Washington

d = The distance travelled each day in miles

We note that the given graphs have number of days in the y-axis and the miles in the x-axis, and that in the function, the distance Crystal travels each day is constant, d, while the 930 is the total distance from California to Washington, while W(d) is the time

Therefore, the variables for crystal are W(d) and the part of 930 miles completed, while the constant is the speed, d = miles/day, which gives;

W(d) = 930/d

W(d) ∝ Part of 930 miles completed × Constant

∴ W(d) which is the time is directly proportional to the distance

The graph which represents the number of days, W(d) it will take Crystal to get to Washington (miles completed) as a function of distance traveled per day, d, which is constant is a straight line graph which is the first graph
