The Current Population Survey conducted by the Census Bureau records the incomes of a large sample of U.S. households each month. What will be the relationship between the mean and median of the collected data
Explanation:
There are 3 possible cases that describe the relationship between the mean and median of the collected data.
First case:
If the distribution is symmetric then, mean = median.
Second case:
For the positively skewed frequency distribution, the mean is greater than the median.
Third case:
For the negatively skewed frequency distribution mean is less than the median.

–2z − 7 need this done now
Answer:
the value of the z is -3.5
Step-by-step explanation:
According to the question, the following information is given
-2z - 7
Based on the above information
We assume that we have to determine the z value
so
-2z - 7 = 0
-2z = 7
z = 7 ÷ -2
= -3.5
Hence, the value of the z is -3.5

which pair of of expressions are equivalent? A. 10(x+4) and 10x+14 B. 3(x+5) and 3x + 5 C. x+x+x+1+1+1 and 3(x+1) D. x+x+x+x+1+1+1+1 and 8x
Answer:
C. x+x+x+1+1+1 and 3(x+1)
Step-by-step explanation:
Algebraic Expressions
Some algebraic expressions are equivalent to others if the correct operations are done on them.
A. 10(x+4) must be operated by multiplying 10 by x and 10 by 4, thus:
10(x+4) = 10x + 40.
This choice is not correct
B. 3(x+5) must be operated by multiplying 3 by x and 3 by 5, thus:
3(x+5) = 3x + 15.
This choice is not correct
C. x+x+x+1+1+1 is equivalent to an expression where like terms are collected, that is. x+x+x=3x and 1+1+1=3, thus:
x+x+x+1+1+1=3x+3=3(x+1)
This choice is correct
D. x+x+x+x+1+1+1+1 in a similar way as explained above, like terms must be correctly collected: D. x+x+x+x=4x and 1+1+1+1=4, thus
D. x+x+x+x+1+1+1+1 = 4x+4 = 4(x+1)
This choice is not correct
PLEASE ANSWER ASAP FOR BRAINLEST!!!!!!!!!!!!!!
Elena gets a base pay of $1,500 per month. She also earns a commission of 8% of the total sales dollars that she makes. What are Elena’s earnings for a month in which she has sales of $32,000?
Answer
4060 DollarsHere's why this is correct
and if Elena gets a base pay of $1,500 per month, then we add 8% of the total sales, ($32,000) and 8% of 32,000 is $2,560.
8% of 32,000 = 2,560
So we add $2,560 by $1,500 and we get 4060 Dollars.

Which of the following represents a function? OA X -5-1 9 8 -1 y 1 7 23 17 1 B. y NS x -4 NO 4 C. {(0,1),(3,2), (-8,3), (-7,2), (3,4)} D. -4 5 9 3 13
Given:
The different relations in the options.
To find:
The relation which represents a function.
Solution:
A relation is called a function if there exist a unique output (y-value) for each input (x-value).
In option A, there exist two outputs y=7 and y=1 for a single input x=-1. So, this is not a function.
In option B, there exist two outputs y=-5 and y=2 for a single input x=-1. So, this is not a function.
In option C, there exist two outputs y=2 and y=4 for a single input x=3. So, this is not a function.
In option D, there exist only one value of y for each x. So, this is a function.
Therefore, the correct option is D.

What is the solution to the system of equations? 2x + 3y = 26 3x + 5y = 40
Answer:
x = 10 , y = 2
Step-by-step explanation:
The solution of the system of equations will be x= 10 and y = 2.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the system of equations is 2x + 3y = 26 and 3x + 5y = 40. the two equations by elimination method can be solved as;-
2x + 3y = 26
3x + 5y = 40
Cross-multiply with the variable of x,
6x + 9y = 78
-6x - 10y = -80
___________
-y = -2
y = 2
The value of x will be:-
2x + 3y = 26
2x + 3 ( 2 ) = 26
2x = 20
x = 10
Hence, the solution of the system of equations will be x= 10 and y = 2.

It's c because you need the sum of x and 10 but both multiplied by 2. So it wouldn't be A nor B because they are both subtracting. That would leave you with C and D and d doesn't have anything to do with multiplying. I dunno made sense to me.

A number increased by five is negative fifteen. What is the number?
Answer:
The value of the number is: n = -20
Step-by-step explanation:
Given
A number increased by five is negative fifteen.
To determine
What is the number?
Let 'n' be the unknown number.
''A number increased by five'' means we have to add 5 to the number.
i.e.
n+5
Also, it is stated that a number increased by five is negative fifteen.
Thus,
[tex]n+5=-15[/tex]solving for n
[tex]n+5=-15[/tex]
Subtract 5 from both sides
[tex]n+5-5=-15-5[/tex]
Simplify
[tex]n=-20[/tex]
Therefore, the value of the number is: n = -20
Let f(x) be an exponential functionWhich transformations to the graph of f(x) would describe e - f(x - 3) ?
Look at the graph below carefully
Observe the results of shifting ={2}^{x}f(x)=2x
vertically:
The domain, (−∞,∞) remains unchanged.
When the function is shifted up 3 units to ={2}^{x}+3g(x)=2x +3:
The y-intercept shifts up 3 units to (0,4).
The asymptote shifts up 3 units to y=3y=3.
The range becomes (3,∞).
When the function is shifted down 3 units to ={2}^{x}-3h(x)=2 x −3:
The y-intercept shifts down 3 units to (0,−2).
The asymptote also shifts down 3 units to y=-3y=−3.
The range becomes (−3,∞).

Answer:
reflection over the x-axistranslation up 'e' units and right 3 unitsStep-by-step explanation:
The transformation ...
g(x) = a×f(x-h) +k
performs a vertical stretch by the factor 'a', and a translation by (h, k), which is h units right and k units up. When 'a' is negative, there is a reflection over the x-axis.
Here, we have 'a' = -1, h = 3, k = 'e'. So, the graph of f(x) has been ...
reflected over the x-axis
translated right by 3 units
translated up by 'e' units

The variable s varies directly as the square of t. When s = 4, t = 12. Nick’s work finding the value of t when s = 48 is shown:
What is the first error, if any, in Nick’s work?
See in pic:
Answer:
C - He substituted incorrectly when calculating the constant of variation.
The first error, in Nick’s work is given inn option C, i.e. He substituted incorrectly when calculating the constant of variation.
What is constant of variation?Constant of variation is the ratio between two variables in a direct variation or the product of two variables in an inverse variation.
We have,
s = 4, and t = 12
Now according to the question,
The variable s varies directly as the square of t,
i.e.
s = kt²
So,
Substituting given values of s and t,
s = kt²
i.e.
4 = k × 12²
⇒
[tex]k = \frac{4}{144}=\frac{1}{36}[/tex],
Now,
for 48,
i.e.
s = kt²,
We get,
[tex]48 = \frac{1}{36} t^2[/tex],
i.e.
[tex]t^2=36 *48=1728[/tex]
[tex]t=\sqrt{1728} = \sqrt{3*576} =24\sqrt{3}[/tex]
So, this is the correct value for t.
Hence, we can say that the first error, in Nick’s work is given inn option C, i.e. He substituted incorrectly when calculating the constant of variation.

The mosquitos have different traits because they have different proteins for body size feature in their cells. Differences in the structure of protein molecules affect how they interact with other protein molecules. A gene version provides instructions for making a specific protein, so mosquitos with different combinations of gene versions will have different proteins in their cells that result in small, medium, or large body sizes. Each parent randomly passes on one of its two copies of a gene for a feature, which is why each mosquito offspring can have a different combination of gene versions even though they have the same parents.
Answer:
The mosquitos have different traits because they have different proteins for body size feature in their cells. Differences in the structure of protein molecules affect how they interact with other protein molecules. Genes provide rules for making particular energy, so mosquitos with different mixtures of genes will have different proteins in their cells that end up in different body sizes. Each parent randomly gives on one out of two of a gene for a characteristic, which is why each mosquito babies can have different mixtures of genes, even though they have the same parents.

a fish is swimming at a contest rate toward the ocean floor. the equation y=-7x-3 can be used to represent to this situation where y is the depth of the fish in meters below se level. x is the number of seconds the fish has been swimming. which staTement best describes the depth of the fish given this equation.
Answer:
C
Step-by-step explanation:
y = -7x - 3 is a linear function that follow y = mx+b. M is the slope or rate. Here m = -7 so the fish descends 7 meters per second. B is the y-intercept or starting position. Here the starting position is -3 so the fish starts 3 feet below sea level.
