Find the 41st term.
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!

If a«b a = 18 when b = 3, then find a when b = 5
I need help asap
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

The children had 2 puzzles with 226 pieces and 4 puzzles with 558 pieces. How many pieces were in the puzzles altogether?
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.
Write the standard form of the equation of the line parallel to the graph of 9x + 3y = 6 that passes through (0,3).
SHOW YOUR WORK
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

(2) Han spent 75 minutes practicing the piano over the weekend. Priya practiced the violin for 152% as much time as Han practiced the piano. How long did she practice? *
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: 48

The gradient function of px²+qx+r is 4x+2.Find p
Step-by-step explanation:
d/dx [px² + qx + r] = 2px + q.
Since 2px + q = 4x + 2, therefore 2p = 4, p = 2.
16% of the town's population are above the age of 65. If there are 320 residents are over the age of 65, approximately what is the town's total population?
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

As Jackson stands near a helicopter landing pad (on the ground), he sees a helicopter approaching. The altitude (height above the ground) of the helicopter is 148 meters. From the helicopter to where Jackson is standing there is an angle of depression of LaTeX: 42^\circ42 ∘.
The direct distance between the helicopter and Jackson is _______ meters.
Round your answer to the nearest meter. Type in only the numerical part of the answer (no units).
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

Consider the following sets of sample 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 B: 21,253, 21,065, 20,747, 21,905, 20,546, 21,580, 22,292, 20,072, 20,518, 20,426, 20,839 Step 1 of 2 : For each of the above sets of sample data, calculate the coefficient of variation, CV. Round to one decimal place.
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%

Step-by-step explanation:
In a study of the relationship between socioeconomic class and unethical behavior, 129 University of California undergraduates at Berkeley were asked to identify themselves as having low or high social class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. They were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. After completing some unrelated tasks, participants reported the number of candies they had taken. It was found that those who were identified as upper-class took more candy than others. For the study, identify:
a. the cases
b. The variables, and their types
c. the main research question
Answer:
Establishing casual relationship
Population of interest : University of California undergraduates
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
How to establish Relationship between socioeconomic class and unethical behavior
Step-by-step explanation:
