Using the slope formula, find the slope of the line through the given points.
(13,0) and (3,-5)
Answer:
1/2 or 0.5
Step-by-step explanation:
Slope (m) =
ΔY/ΔX=
1/2=
0.5
(more in depth)
ΔX = 3 – 13 = -10
ΔY = -5 – 0 = -5
-10/-5 = 1/2 = 0.5

Answer:
60 squaer feet
So lets seperate the shapes one for the bottom small chunk and one for hte big long large top chunk.
To find area you do height times width. So the bottom would be 3 times 4 which is 12 square feet.
Now the top part would be 4+4+4 which is 12 then times that by 4 and get 48.
Now you add 48 and 12 and you get 60 square feet!
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:
A)The cases
Establishing casual relationship
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

Which of the following ordered pairs represents a solution to the equation below?
y = -2x-1
Choose 1 answer:
(-2,2)
(-1,0)
(0, -3)
(1,-4)
(2, -5)
Answer:
(2,-5)
Step-by-step explanation:
To solve this, simply substitute the values for x and y. The only one that works is (2,-5).
-5 = -2(2) -1
-5 = -4 - 1
-5 = -5

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%

PLZ HELP FIND THE PERIMETER
Answer:
254 ft
Step-by-step explanation:
first find the legs of the triangle.
you already know 65, and you would get another leg by 83-50, which equals 33.
Next use pythagorean theorem to find the other leg
a^2+b^2=c^2
rearrange so you find a leg
a^2=c^2-b^2
a^2=65^2-33^2
a^2=4225-1089
a^2=3136
a=56
Now you know that the missing leg is 56. Since that leg is the same as the short side of the rectangle, you 83+50+65+56=254

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).
