Answer:
f(-x)= -f(x) so, the given function \(f(x)= x^3-2x\) is Odd
Step-by-step explanation:
We need to determine if the function \(f(x)= x^3-2x\) is Even, Odd, or Neither.
Determining if a function f(x) is even or not we put x=-x and check
If f(-x)=f(x) the function is even
if f(-x)= -f(x) the function is odd
So, Putting x =-x and determining if the given function \(f(x)= x^3-2x\) is Even, Odd, or Neither.
\(f(x)= x^3-2x\\Put \ x=-x\\f(-x)=(-x)^3-2(-x)\\f(-x)=-x^3+2x\\f(-x)=-(x^3-2x)\\f(-x)=-f(x)\)
As f(-x)= -f(x) so, the given function \(f(x)= x^3-2x\) is Odd

The last box 2/37.5 = 4/75 = 0.8/15 have same proportional relationship.
what is proportional relationship?
When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. In a proportional connection, one variable is always a constant value multiplied by the other, which is another way to think of them. The "constant of proportionality" is the term used to describe that constant.
Given x and y will have a proportional relationship if the ratio of x to y will be equal for all given values.
9/8 ≠ 12/8
16/28 = 4/7 ≠6/10.5
12/32= 3/8 ≠8/20

if q is inversely propotional to p, and q= 120 when p=2, form an equation connecting p and q and calculate q when p=5
Answer:
q = 108/p
Explanation:
the initial statement is q ∝ 1 /p
to convert to an equation multiply by k the constant of variation
⇒ q = k × 1 /p = k /p
to find k use the given condition
q = k/ p
⇒ k = q/ p = 3 /2 × 72 = 108
equation is q = 108/ p
Answer:
q = 48
Step-by-step explanation:
Given q is inversely proportional to p then the equation relating them is
q = \(\frac{k}{p}\) ← k is the constant of proportion
To find k use the condition q = 120 when p = 2 , then
120 = \(\frac{k}{2}\) ( multiply both sides by 2 )
240 = k
q = \(\frac{240}{p}\) ← equation of proportion
When p = 5 , then
q = \(\frac{240}{5}\) = 48
At Jefferson High school there are 250 students who drive to school and 375 students who ride the bus to school. The number of students who drive to school is blank% of the number of students who ride the bus to school.
Answer:66.67%
Step-by-step explanation: At Jefferson High School, there are 250 students who drive to school and 375 students who ride the bus to school. To find the percentage of students who drive to school compared to the number of students who ride the bus to school, we can divide the number of students who drive to school by the number of students who ride the bus to school and multiply by 100%:
(250 / 375) * 100% = (2/3) * 100% = 66.67%
So the number of students who drive to school is 66.67% of the number of students who ride the bus to school. Is there anything else you would like to know?

Each histogram represents a set of data with a median of 29.5. Which set of data most likely has a mean that is closest to 29.5?
A graph shows the horizontal axis numbered 9 to 48. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 33 then a downward trend from 33 to 45.
A graph shows the horizontal axis numbered 15 to 48. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 30 then a downward trend from 30 to 45.
A graph shows the horizontal axis numbered 12 to 56. The vertical axis is numbered 2 to 8. The graph shows an upward trend from 1 to 32 then a downward trend from 32 to 56.
A graph shows the horizontal axis numbered 15 to 54. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 24, a downward trend from 24 to 27, an upward trend from 27 to 30, a downward trend from 30 to 39, an upward trend from 39 to 45, a downward trend from 45 to 48, then an upward trend from 48 to 51.
To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.
Looking at the histograms described:
The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.
The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.
The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.
The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.
Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.

Adi bought a bag for $25 and sold it at a loss of 10%. Find the selling price of the bag.
Answer:
The selling price of the bag is $22.5
Step-by-step explanation:
Buying Price = $25,
Selling Price = ?
Since they sold it at a loss of 10%,
So, they sold it for a price 10% less than the buying price,
or at 90% or 0.9 of the buying price,
so,
Selling Price = (0.9)(25) = $22.5

construct a box plot from the given data. diameters of cans in an assembly line: 5.7,5.6,5.1,5.4,5.2,5.6,5.7,5.3,5.8,5.2
The resulting box plot for the given data would show a box ranging from 5.2 to 5.7, with the median at 5.4.
A box plot, also known as a box-and-whisker plot, is a graphical representation of numerical data that displays the distribution of a dataset. It provides a visual summary of the minimum, first quartile, median, third quartile, and maximum values, as well as any outliers that may be present.
To construct a box plot from the given data (diameters of cans in an assembly line: 5.7, 5.6, 5.1, 5.4, 5.2, 5.6, 5.7, 5.3, 5.8, 5.2), follow these steps:
1. Sort the data in ascending order: 5.1, 5.2, 5.2, 5.3, 5.4, 5.6, 5.6, 5.7, 5.7, 5.8.
2. Find the median (middle value) of the dataset, which is 5.4.
3. Determine the first quartile (Q1), which is the median of the lower half of the data. In this case, it is the median of the numbers below 5.4: 5.2.
4. Find the third quartile (Q3), which is the median of the upper half of the data. In this case, it is the median of the numbers above 5.4: 5.7.
5. Calculate the interquartile range (IQR) by subtracting Q1 from Q3: 5.7 - 5.2 = 0.5.
6. Identify any outliers in the dataset. Outliers are values that fall below Q1 - 1.5 * IQR or above Q3 + 1.5 * IQR. In this case, there are no outliers.
7. Construct the box plot using a number line. Draw a box from Q1 to Q3, with a line inside representing the median. Add whiskers (lines) extending from the box to the minimum value (5.1) and the maximum value (5.8).
The resulting box plot for the given data would show a box ranging from 5.2 to 5.7, with the median at 5.4. The whiskers would extend from 5.1 to 5.8. This visual representation provides an overview of the distribution and key statistical measures of the diameters of cans in the assembly line.

A random sample of 25 U.S. residents was selected using census data from the year 2000. The dotplot below shows the distribution of total personal income (in thousands) for the members of the sample. The mean of this distribution is $25,615 and the standard deviation is $25,333.What percent of the sample had total personal incomes within two standard deviations of the mean?
Answer:
95%
Step-by-step explanation:
Data falls within 2 standard deviations from the mean - is calculated using;
μ – 2σ and μ + 2σ .
The mean of this distribution is $25,615 and the standard deviation is $25,333.
μ – 2σ
= $25,615 - 2($25,333)
=$-25051
μ + 2σ
= $25,615 + 2($25,333)
= 76,281
Empirical rule states that: 95% of data falls within 2 standard deviations from the mean
Hence, 95% the sample had total personal incomes within two standard deviations of the mean.

An equation to represent how he got $460.65 as take home pay is:
15x - (.17× (15x) ) = 460.65
15x tells us how much money he earned in total. We also multiply that by .17 to determine how much goes to taxes. Then, we subtract taxes from total, and put that equal to our take home pay
