20 students each rolled dice 5 times each to measure the median. Here is the data in the picture attached. What can we infer from this graph by looking at the median data?
A. when rolling a dice multiple times, the median is less likely to fall between numbers 1 and 6.
B. it's not possible to tell the likelihood of where the median is going to be when measuring probability since rolling dice is completely randomized, etc.
C. some other response
We can deduce that option A is likely to be true based on the given graph of rolling dice median data.
What is the median?The median is the value in the middle of a data set, which means that 50% of the data points have a value less than or equal to the median, and 50% of the data points have a value greater than or equal to the median.
The graph illustrates that the median value of the rolls is closer to the center of the possible outcomes (numbers 3, 4, and 5) than the extremes (numbers 1 and 6).
This implies that when rolling a dice several times, the median is less likely to fall between the numbers 1 and 6.
However, because rolling the dice is a random process, there is always a degree of uncertainty in predicting the outcomes.

Answer: The top right table
-------------------------------------------------------------------------------------------------------------
Given: \(\textsf{y = 30 - 3x}\)
Find: \(\textsf{Match the table of values with the equation}\)
Solution: First we must understand what form our equation is in and what each of the numbers represent. This form is known as the slope intercept form which is formatted as y = mx + b. Our equation is slightly re-ordered but we can change that by converting it to y = -3x + 30 where m is equal to -3 and b is equal to 30. Let us know talk about what m and b are. M is the slope of the equation or also known as the rise/run or the change in y over the change in x. B is the y-intercept which is basically the value of y when x is equal to 0. In this case, our b is equal to 30.
Looking at the tables we can see what the value of y when x is equal to 0 for each table. The only table that matches up stating that y is equal to 30 when x is 0 is the top right table.
You do not have to go any further but if you want to confirm that the slope is as expected we can do the following: \(\frac{y_2\ -\ y_1}{x_2\ -\ x_1}\).
Plug in the values and simplify
\(\frac{48\ -\ 30}{-6\ -\ 0}\)\(\frac{18}{-6}\)\(-3\)Therefore, we can confirm that the slope matches up with the given equation as well. So, the final answer would be that the top right table would correspond to the equation y = 30 - 3x.

Is y=-5x+1 and x-5y=30 perpendicular or parallel
Answer:
Perpendicular lines
Step-by-step explanation:
Parallel lines have the same slope. In contrast, perpendicular lines have negative reciprocal slopes, in which the product of the slopes of two lines result in -1.
Given the two linear equations, y = -5x + 1 and x - 5y = 30:
Transform x - 5y = 30 into its slope-intercept form, y = mx + b:
x - 5y = 30
x - x - 5y = - x + 30
-5y = -x + 30
Divide both sides by -5:
\(\frac{-5y}{-5} = \frac{-x + 30}{-5}\)
\(y = \frac{1}{5}x - 6\) (This is the slope-intercept form of the second equation, x - 5y = 30).
Now that we have both equations, it is easier to see that they have negative reciprocal slopes:
y = -5x + 1 ⇒ slope = -5
\(y = \frac{1}{5}x - 6\) ⇒ slope = 1/5
Multiplying their slopes together: -5 × 1/5 = -1. Therefore, these equations represent perpendicular lines.

The sales tax for an item was $21.70 and it cost $310 before tax.
Find the sales tax rate. Write your answer as a percentage.
Answer:
\(Sales \ Tax \ Amount = Net \ Price \cdot \frac{Sales \ Tax \ percentage}{100}\)
\(21.70 = 331.70 \cdot \frac{sales\ tax \ percentage}{100} \\\\\frac{21.70}{331.70} = \frac{sales\ tax \ percentage}{100}\\\\0.0654 = \frac{sales\ tax \ percentage}{100}\)
Sales Tax Percentage = 0.0654 × 100 = 6.54%
A local city park rents kayaks for $3.75 per hour. If a customer rents for four or more hours, the cost is only $3.25 per hour, plus a $5 processing fee. If C(x) represents the total cost and x represents the number of rental hours, which of the following functions best models this scenario?
C of x equals 3.75 times x if x is less than 6 and 3.25 plus 5x if x is greater than 6.
C of x equals 3.75 times x if x is less than or equal to 5 and 3.25x minus 5 if x is greater than 6.
C of x equals 3.75 times x if x is less than 6 and 3.25x plus 5 if x is greater than or equal to 6.

Consider this equation
1/x-1 = | x-2 |
Using three iterations of successive approximation, what is the approximate solution to the equation? Use the graph as a starting point.
A. x ≈ 43/16
B. x ≈ 21/8
C. x ≈ 41/16
D. x ≈ 19/8
The approximate solution to the equation 1/x-1 = |x-2| after three iterations of successive approximation is x ≈ 5/2 or x ≈ 2.5.
To solve the equation 1/x-1 = |x-2| using three iterations of successive approximation, we will start with an initial guess and refine it using an iterative process.
Given that the equation involves absolute value, we will consider two cases:
Case 1: x - 2 ≥ 0
In this case, |x-2| simplifies to x-2, and the equation becomes 1/(x-1) = x-2.
Case 2: x - 2 < 0
In this case, |x-2| simplifies to -(x-2), and the equation becomes 1/(x-1) = -(x-2).
Now, let's perform the successive approximation:
Iteration 1:
Let's start with an initial guess, x = 2.
Case 1: When x - 2 ≥ 0,
1/(2-1) = 2-2,
1/1 = 0,
which is not true.
Case 2: When x - 2 < 0,
1/(2-1) = -(2-2),
1/1 = 0,
which is not true.
Since our initial guess did not satisfy the equation in either case, we need to choose a different initial guess.
Iteration 2:
Let's try x = 3.
Case 1: When x - 2 ≥ 0,
1/(3-1) = 3-2,
1/2 = 1,
which is not true.
Case 2: When x - 2 < 0,
1/(3-1) = -(3-2),
1/2 = -1,
which is not true.
Again, our guess did not satisfy the equation in either case.
Iteration 3:
Let's try x = 2.5.
Case 1: When x - 2 ≥ 0,
1/(2.5-1) = 2.5-2,
1/1.5 = 0.5,
which is true.
Case 2: When x - 2 < 0,
1/(2.5-1) = -(2.5-2),
1/1.5 = -0.5,
which is not true.
Our guess of x = 2.5 satisfies the equation in Case 1.
Therefore, the approximate solution to the equation 1/x-1 = |x-2| after three iterations of successive approximation is x ≈ 5/2 or x ≈ 2.5.

Don and Celine have been approved for a $400,000, 20-year mortgage with an APR of 3.35%. Using the mortgage and interest formulas, set up a two-month amortization table with the headings shown and complete the table for the first two months.
To set up the amortization table, we can use the mortgage and interest formulas as follows:
Mortgage formula:
M = P [ i(1 + i)^n / (1 + i)^n - 1]
where M is the monthly payment, P is the principal (the amount borrowed), i is the monthly interest rate (APR divided by 12), and n is the total number of payments (20 years multiplied by 12 months per year).
Interest formula:
I = P * i
where I is the monthly interest payment, P is the remaining principal balance, and i is the monthly interest rate.
Using these formulas, we can set up the following amortization table for the first two months:
Month Payment Principal Interest Balance
1 $400,000
2
To fill in the table, we need to calculate the monthly payment (M) and the monthly interest payment (I) for the first month, and then use these values to calculate the principal payment for the first month. We can then subtract the principal payment from the initial balance to get the balance for the second month, and repeat the process to fill in the remaining columns.
To calculate the monthly payment (M), we can use the mortgage formula:
M = P [ i(1 + i)^n / (1 + i)^n - 1]
where P is the principal amount, i is the monthly interest rate, and n is the total number of payments.
Plugging in the given values, we get:
M = 400,000 [ 0.00279 (1 + 0.00279)^240 / (1 + 0.00279)^240 - 1]
M = $2,304.14
Therefore, the monthly payment is $2,304.14.
To calculate the interest payment for the first month, we can use the interest formula:
I = P * i
where P is the remaining principal balance and i is the monthly interest rate.
Plugging in the values for the first month, we get:
I = 400,000 * 0.00279
I = $1,116.00
Therefore, the interest payment for the first month is $1,116.00.
To calculate the principal payment for the first month, we can subtract the interest payment from the monthly payment:
Principal payment = Monthly payment - Interest payment
Principal payment = $2,304.14 - $1,116.00
Principal payment = $1,188.14
Therefore, the principal payment for the first month is $1,188.14.
To calculate the balance for the second month, we can subtract the principal payment from the initial balance:
Balance = Initial balance - Principal payment
Balance = $400,000 -$1,188.14
Balance = $398,811.86
Therefore, the balance for the second month is $398,811.86.
Using these values, we can complete the first two rows of the amortization table as follows:
Month Payment Principal Interest Balance
1 $2,304.14 $1,188.14 $1,116.00 $398,811.86
2
To fill in the remaining columns for the second month, we can repeat the process using the new balance of $398,811.86 as the principal amount for the second month. We can calculate the interest payment using the same method as before, and then subtract the interest payment from the monthly payment to get the principal payment. We can then subtract the principal payment from the balance to get the new balance for the third month, and repeat the process for the remaining months of the amortization period.
If f(x)=x²-3 x+5 and g(x)=-2 x, find the following composition. (f°g)(2)
(f°g)(2)=__ (Simplify your answer.)
The value of the funciton of function f(g(x)) for x = 2 is that f(g(2)) is 33.
What is a function?The function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
As per the given function,
f(x) = x² -3x + 5 and g(x) = -2x
f(g(x)) = f(-2x)
Since the operation of f(x) is x²-3 x+5.
So, f(-2x) = (-2x)² - 3(-2x) + 5
f(g(x)) = 4x² + 6x + 5
The value of the combined function for x = 2 is
f(g(2)) = 4(2)² + 6(2) + 5
⇒ 16 + 12 + 5 = 33
Hence "The value of the funciton of function f(g(x)) for x = 2 is that f(g(2)) is 33".

Find the x- and y-intercepts, if possible.
Describe the interval(s) on which the function is continuous. (Enter your answer using interval notation.) f(x) = x + 4 / sqrt(x).
The function \(f(x)\) = x + 4 / \(\sqrt{x}\) is continuous on the interval (0,∞).
The domain of the function, which is all real numbers greater than zero, determines this interval. To put it another way, the function is defined for all real number larger than zero. The function range includes all real numbers bigger than 4.
Because there are no discontinuities in the domain, the function is continuous. The function denominator, \(\sqrt{x}\) , is never 0, hence the denominator can never be zero, and so there are no holes or jumps in the graph.
The function is also continuous since its limit as x approaches 0 is 4. This indicates that when x = 0, the function is continuous. As x increases, the function increases as well, so it is also continuous at the right endpoint of the interval, which is infinity.
