What angle is this someone please help

Answer:

a = 30

Step-by-step explanation:

Given the following data;

a = 18

b = 3

This is a direct proportion question.

Therefore, a is directly proportional to b.

Mathematically, a = kb

First of all we would find the constant, k;

k = a/b

k = 18/3

k = 6

Now to find the value of a when b = 5

a = kb

a = 6*5

a = 30

Answer:

16.6% ; 3.2%

Step-by-step explanation:

Given the data :

Data A:

$36,700, $30,300, $22,800, $27,700, $37,700, $39,800, $27,000, $30,100, $33,900, $24,900, $27,500, $37,600, $32,700, $34,200

Data B: 21,253, 21,065, 20,747, 21,905, 20,546, 21,580, 22,292, 20,072, 20,518, 20,426, 20,839

The Coefficient of variation (CV) = (Sample standard deviation / Sample mean)

Sample mean (m) ;

Σx / n

n = sample size

Sample standard deviation (S) :

√[(x - m)² / (n-1)]

To save computation time ;

The sample mean and sample standard deviation can be obtained using a calculator :

For Data A:

Sample mean (m) = 31635.7143

Sample Standard deviation (s) = 5256.14763

Hence, Coefficient of variation :

5256.14763 / 31635.7143

= 0.166

= 0.166 * 100% = 16.6%

For Data B:

Sample mean (m) = 21022.0909

Sample Standard deviation (s) = 678.718271

678.718271 / 21022.0909

= 0.032

= 0.032 * 100% = 3.2%

Answer:

324

Step-by-step explanation:

All you're simply doing is adding 8 to each number up until the 41st term OR an easier way, using the arithmetic sequence formula as shown below in the red box:

an is the term you want to find, in this case: the 41st term.

a1 is the first term in the list of ordered numbers

n is the term position, in this case, the same as an

d is the difference whether if it's adding or subtracting.

Now match the numbers in the formula and solve using PEMDAS from left to right!

Answer:

Priya practiced for 114 minutes (1 hour and 54 minutes).

Step-by-step explanation:

Percentages

To find a percentage of a given number, the procedure is multiplying the percentage by the number and divide by 100.

Han spent 75 minutes practicing the piano over the weekend and Priya practiced the violin for 152% of the time that Han did.

We need to compute:

[tex]\frac{152*75}{100}=\frac{11400}{100}= 114[/tex]

Priya practiced for 114 minutes (1 hour and 54 minutes).

Answer:

2884 pieces

Step-by-step explanation:

First you have to multiply 2 and 226:

2 x 266 = 532

Then you have to multiply 4 and 558:

4 x 558 = 2352

After that you have add those two to make your answer:

532 + 2352 = 2884

There is your answer.

Answer:

D=221 m

Step-by-step explanation:

In order to solve this problem, we can start by drawing a diagram of the given situation. (see attached picture)

As you may see, we have a right triangle there, so we can use trigonometric functions to solve this. Specifically, the sine function.

[tex]sin \theta = \frac{OS}{Hyp}[/tex]

in this case we need to find the hypotenuse, so we solve the equation above for the Hyp, so we get:

[tex]Hyp= \frac{OS}{sin \theta}[/tex]

in this case, the opposite side (OS) is the heght of the helicopter, the angle is the 42° and the Hyp is the direct distance between the helicopter and Jackson, so we substitute the given data to get:

[tex]Distance=\frac{148m}{sin 42^{o}}[/tex]

Which yields:

D=221m

Answer:

Step-by-step explanation:

12 : 24 : 16  ⇒  Find their highest common factor. In this case it's 4.

3 : 6 : 4  ⇒  Divide the ratio by the HCF.

Answer:

y + 3x = 3

Step-by-step explanation:

Standard Form of the Equation of a Line

The equation of a line in standard form is:

Ax + By = C

Where A, B, and C are constants.

The equation of a line can also be expressed in slope-intercept form, where m is the slope, and b the y-intercept:

y = mx + b

Two lines are parallel if they have the same slope, that is if m1 is the slope of a given line, and m2 is the slope of a parallel line, then m2=m1.

We are given the line:

9x + 3y = 6

Dividing by 3:

3x + y = 2

Solving for y:

y = -3x + 2

The slope of this line is m1=-3, thus the slope of the required line is also m2=-3.

The equation of that required line is:

y = -3x + b

We still don't have the value of b. To find it, we substitute the coordinates of the given point (0,3):

3 = -3(0) + b

Thus, b = 3.

The required equation of the line is:

y = -3x + 3

To write it in standard form, we add 3x:

y + 3x = 3

Step-by-step explanation:

d/dx [px² + qx + r] = 2px + q.

Since 2px + q = 4x + 2, therefore 2p = 4, p = 2.

Answer:

the total population is 2,000

Step-by-step explanation:

so if we double 16 we get 32% and we have 640 residents then we ad 8% which gets us to an even number of 40% and therefor we add half the 16% to our 640 to get 800 and this is sounding complicated but stick with me. now that we have 40% of the population is 800 people then 80% is 1,600 then we add half or 20% and get 100% is 2,000 people

How to establish Relationship between socioeconomic class and unethical behavior

Step-by-step explanation:

A)The cases

Population of interest : University of California undergraduates

B) The variables and types

Sample size : 129 university of California undergraduates

Generalized to population : It depends if the 129 students where picked randomly within the school i.e. considering the fat that every individual represents a certain culture present in the school's population

C) The main research question

How to establish Relationship between socioeconomic class and unethical behavior

conclusion : This cannot be used to establish casual relationship because it is a randomized experiment

Answer:

it's D

Step-by-step explanation:

step 1 : add all the numbers

=240

step 2: divide the total by how many numbers there are

240÷4

=60

Answer:

OD)60

Step-by-step explanation:

100+80+40+20=240
