a survey among tenants of shared apartments asked each tenant what percentage of the cleaning around the apartment he or she does. the survey found that aggregating the percentages for each apartment produces an average of much more than 100%. this result may be due to what bias?
The result of an average of more than 100% in a survey of tenants on cleaning chores in shared apartments is likely due to social desirability bias.
The average tenant response of more than 100% in a study about cleaning duties in shared apartments is probably the product of social desirability bias. Social desirability bias occurs when respondents give answers that they think are socially acceptable or desirable, rather than their true opinions or behavior.
In this case, tenants may have overstated their contribution to cleaning the apartment, in order to appear more helpful or responsible, leading to an average percentage higher than 100%.

What are all values of x for which the graph of y = x^4 - 6x^2 + x is concave downward? Show your work and justify your answer.
Answer:
A function is concave downward if its second derivative is negative. To find the values of x for which the graph of y = x^4 - 6x^2 + x is concave downward, we need to find the values of x for which the second derivative of y is negative.
The second derivative of y = x^4 - 6x^2 + x is y'' = 12x^2 - 12x
To find the values of x for which y'' is negative, we need to find the roots of the equation 12x^2 - 12x = 0.
We can factor the equation as: 12x(x-1) = 0
which gives us x = 0 and x = 1 as the roots.
Now, we need to test the sign of the second derivative in the intervals between the roots.
In the interval (0,1)
y'' = 12x^2 - 12x is positive, therefore the function is not concave downward in this interval.
In the interval (-infinity,0)
y'' = 12x^2 - 12x is negative, therefore the function is concave downward in this interval.
In the interval (1,infinity)
y'' = 12x^2 - 12x is negative, therefore the function is concave downward in this interval.
Therefore, the values of x for which the graph of y = x^4 - 6x^2 + x is concave downward are all values of x less than 0 or greater than 1.

When parking a car in a downtown parking lot, drivers pay according to the number of hours or fraction thereof. The probability distribution of the number of hours cars are parked has been estimated as follows:
A. Mean=
B. Standard Deviation=
The cost of parking is 5 dollars per hour. Calculate the mean and standard deviation of the amount of revenue each car generates.
A. Mean=
B. Standard Deviation
col1 X 1 2 3 4 5 6 7 8
col2 P(X) 0. 229 0. 113 0. 114 0. 076 0. 052 0. 027 0. 031
0. 358
The mean is 24.2 and the standard deviation is 8.7.
MeanThe mean amount of revenue each car generates can be calculated by multiplying the mean number of hours parked by the cost per hour. To find the mean number of hours parked, we need to multiply each possible number of hours by its probability and add them up.
E(X) = (1 * 0.229) + (2 * 0.113) + (3 * 0.114) + (4 * 0.076) + (5 * 0.052) + (6 * 0.027) + (7 * 0.031) = 4.84 hours
So, the mean revenue is 4.84 * 5 = 24.2 dollars
Standard DeviationThe standard deviation of the revenue can be calculated by finding the standard deviation of the number of hours parked and then multiplying by the cost per hour.
SD(X) = sqrt( (1^2 * 0.229) + (2^2 * 0.113) + (3^2 * 0.114) + (4^2 * 0.076) + (5^2 * 0.052) + (6^2 * 0.027) + (7^2 * 0.031) - (4.84)^2) = 1.74 hours
So, the standard deviation of the revenue is 1.74 * 5 = 8.7 dollars.

Broderick has $420 in his checking account. He made 6 deposits of 35. 50 each. He needs to write 6 checks for 310. 75 each
Broderick needs $610.00 in his account to cover his checks.
We know that the balance Boderick has is $420.
First, we will calculate the total amount of the 6 deposits made by Broderick each of $35.50 deposit as follows -
$35.50 x 6 = $213.00
Hence, the total amount of the 6 deposits made by Broderick is $213.00
Next, we will calculate the total amount of the 4 checks he needs to write-
$310.75 x 4 = $1243.00
Hence, the total amount of the 4 checks that Broderick needs to write is $1243.00
Now we will find the final balance of Broderick's account after all the deposits and check withdrawals. We can do this by adding the total amount of the deposits to his initial balance and subtracting the total amount of the checks as follows-
$420.00 + $213.00 - $1243.00 = -$610.00

Samuel buys 3 bottles of juice that each have an original price of 2.80. He uses a coupon for 35% off. Then, he is changed sales tax at a rate of 6.5%. How much does samuel pay 3 bottles of juice?
Samuel pay 5.81 for the 3 bottles of juice.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
Samuel buys 3 bottles of juice that each have an original price of 2.80.
And, He uses a coupon for 35% off. Then, he is changed sales tax at a rate of 6.5%.
Here, The original cost of 3 bottles of juice = 3 × 2.80
= 8.40
Now, He uses a coupon for 35% off.
Hence, The off price = 35% of 8.40
= 35/100 × 8.40
= 2.94
So, The amount of 3 bottles of juice = 8.40 - 2.94
= 5.46
And, He is changed sales tax at a rate of 6.5%.
Thus, The sales tax on bottles = 6.5% of 5.46
= 6.5/100 × 5.46
= 0.35
Thus, The actual amount of 3 bottles of juice = 5.46 + 0.35
= 5.81

Which are solutions of the equation 4x2 – 7x = 3x + 24? Check all that apply
Answer:
x=5/2 and x=0
Step-by-step explanation:
To solve this equation, we first need to get all the terms on one side of the equation by subtracting 3x from both sides:
4x^2 - 7x - 3x = 24
Simplifying, we get:
4x^2 - 10x = 24
Now, we can factor out the GCF (Greatest common factor) on the left side of the equation:
2x(2x-5) = 24
Now we can divide both sides of the equation by 2x(2x-5) to get the solutions for x:
x = 5/2 , x = 0
So the solutions of the equation 4x^2 - 7x = 3x + 24 are x=5/2 and x=0
Explain why the value of 0.6 is greater than the value of 0.39.
A 0.39 is greater than 0.6 because 9 hundredths is greater than 6 tenths.
B 0.39 is less than 0.6 because 3 tenths is less than 6 tenths.
C 0.6 is greater than 0.39 because 6 tenths is greater than 9 hundredths.
D 0.6 is less than 0.39 because 6 tenths is less than 9 hundredths.
The value of 0.6 is greater than the value of 0.39 because; C 0.6 is greater than 0.39 because 6 tenths is greater than 9 hundredths.
How to evaluate decimal number digits?When we are talking about decimals, the left hand side before the decimal are referred to as whole numbers while the first digit after the decimal represents the tenths place, the next digit after the tenths place represents the hundredths place, the next digit after the hundredths place represents the thousandths place and so on.
Now, we are given two decimals 0.6 and 0.39.
We see clearly that 0.6 has a greater tenths digit than the hundredths digit in 0.39. This is seen as;
0.6 = 6/10 while 0.39 = 39/100

Answer: 77 degrees
Step-by-step explanation:
Ratio of the angles = 5 : 7 : 9 = 5x : 7x : 9x
5x + 7x + 9x = 21x
180 = 21x
x = 180/21
Largest angle = 9x,
= 9 * 180/21
= 540/7

The apothem of a regular pentagon exists [tex]$4.6797 \mathrm{~cm}$[/tex], and the perimeter exists [tex]$34 \mathrm{~cm}$[/tex]. The area equals [tex]$79.55 \mathrm{~cm}^2$[/tex].
What is meant by regular pentagon?It is a regular pentagon if all of its sides and angles are equal in size. It is not normal if not. Each angle inside the regular pentagon is 108°, while each angle outside is 72°. There are 5 equal sides in an equilateral pentagon.
Five congruent sides (sides of identical length), five congruent inner angles (each measuring 108°), and five congruent outer angles of 72° are necessary for a regular pentagon to exist.
If a polygon's sides and angles are equal, it is said to be regular. As a result, an equilateral triangle is a regular triangle, and a regular quadrilateral is a square.
Therefore, the correct answer is option c) The apothem of a regular pentagon is [tex]$4.6797 \mathrm{~cm}$[/tex], and the perimeter is [tex]$34 \mathrm{~cm}$[/tex]. The area equals [tex]$79.55 \mathrm{~cm}^2$[/tex].

This suggests that the translation vector [tex]$\mathbf{t}$[/tex] has a component of -1 in the y-direction. Therefore, we have:
t=(3,−1)
How to find translation vector?To find the translation vector that maps quadrilateral ABCD to quadrilateral $A"B"C"D"$, we can subtract the coordinates of corresponding vertices. Let $\mathbf{t}$ be the translation vector. Then:
[tex]$$ \begin{align*}\\\mathbf{A}" - \mathbf{A} &= \langle -3 - t_x, -3 - t_y \rangle - \langle -3, -2 \rangle \\\&= \langle -3 - t_x + 3, -3 - t_y + 3 \rangle \\\&= \langle -t_x, -t_y \rangle\end{align*} $$[/tex]
Similarly, we have:
[tex]$$ \begin{align*}\mathbf{B}" - \mathbf{B} &= \langle 0 - t_x, -1 - t_y \rangle - \langle 0, -2 \rangle \\\&= \langle -t_x, 1 - t_y \rangle \\\\\\mathbf{C}" - \mathbf{C} &= \langle 1 - t_x, -3 - t_y \rangle - \langle 1, 0 \rangle \\\&= \langle -t_x, -3 - t_y \rangle\end{align*}[/tex]Since [tex]$\mathbf{D}"$[/tex] is not given, we cannot use it to solve for the components of [tex]$\mathbf{t}$[/tex]. However, note that the x-coordinate of [tex]$\mathbf{A}"$[/tex] is -3, which is 3 less than the x-coordinate of [tex]$\mathbf{A}$[/tex]. This suggests that the translation vector [tex]$\mathbf{t}$[/tex] has a component of 3 in the x-direction. Similarly, the y-coordinate of [tex]$\mathbf{B}"$[/tex] is -1, which is 1 more than the y-coordinate of [tex]$\mathbf{B}$[/tex]. This suggests that the translation vector [tex]$\mathbf{t}$[/tex] has a component of -1 in the y-direction. Therefore, we have:
t=(3,−1)
which means that the correct answer is [tex]$\boxed{\langle 3, -1 \rangle}$[/tex]
