Answer:
measure of variability
Step-by-step explanation:
Measure of variability shows the extent in which data in a statically distribution differ from an average value as well as how they differ from each other. It shows how much the data falls from the center value (mean) showing the width of the distribution. The most used measures of variability are the range, interquartile range, variance, and standard deviation depending on the data to be measured.

Answer:
A/m=-2. since x goes up by 2 on the table, y decreases by 4 on the table, but if the next part of x on the table was 6, then y would be -2.
What is the value of x/3y, when x = 18 and y = 3? 3/18 <- this means three over 18 if you don't know 2 3 6
Answer:
2
Step-by-step explanation:
So the first step is to replace the variables with the numbers.
So it then becomes 18/3(3)
18/9
the answer is 2

It takes Kevin 15 minutes to drive 5 1/2 miles.
How many miles does Kevin drive per minute?
a) 11/30
b) 5/6
c)2 8/11
d) 3
Answer: 11/30 miles per minute
Step-by-step explanation:
To get miles per minute
Divide the distance by the time
5 1/2 ÷ 15 . Change 5 1/2 to an improper fraction 11/2
invert the divisor and multiply: (Multiply by the reciprocal of 15: 1/15)
11/2 × 1/15 = 11/30
Here, we are required to determine how many miles does Kevin drive per minute.
The number of miles Kevin drives per minute is 0.3667miles.According to the question, Kevin drives 5 1/2 miles (5.5 miles) in 15 minutes.
To determine how many miles Kevin drives per minute, we need to determine Kevin's speed over the 15 minutes in which he covered 5.5 miles.
Speed = distance/timeSpeed = 5.5miles/15minutes
Therefore, Speed = 0.3667 miles per minute.
Ultimately, Kevin drives 0.3667miles per minute.

Use the function rule \(f\)(x)=3\(x\)-2. Find the output \(f\)(1.5).
Answer:
To find the output of the function f(x) = 3x - 2 when x = 1.5, we simply substitute 1.5 for x in the function rule and simplify:
f(1.5) = 3(1.5) - 2
f(1.5) = 4.5 - 2
f(1.5) = 2.5
Therefore, the output of the function f(x) when x = 1.5 is 2.5.
Answer:
f(x)- x = 1.5 is 2.5.

If xx and y vary directly and y is 21 when x is 7, find y when x is 5
Answer:
y = 15
Step-by-step explanation:
We need to solve for k
y = x
21 = 7k Divide both sides by 7 to solve for k
3 = k
y = xk
y = 5(3)
y = 15
Answer: y = 15
Step-by-step explanation:
Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

A Rectangle has a perimeter of 78 inches. The width,w is 4 less than twice the length. What is the width of the rectangle???
Need explanation/ work
answer/equation
Need help ASAP!!
Answer:24.66 inches.
Step-by-step explanation:
Let's start by using algebra to set up a system of equations to represent the given information.
Let L be the length of the rectangle and W be the width of the rectangle.
From the problem, we know that:
The perimeter of the rectangle is 78 inches, which means that 2L + 2W = 78.
The width is 4 less than twice the length, which means that W = 2L - 4.
We can use the second equation to substitute W in terms of L in the first equation, and solve for L:
2L + 2(2L - 4) = 78
2L + 4L - 8 = 78
6L = 86
L = 14.33 (rounded to 2 decimal places)
Now that we know the length, we can use the second equation to find the width:
W = 2L - 4 = 2(14.33) - 4 = 24.66 (rounded to two decimal places)
Therefore, the width of the rectangle is approximately 24.66 inches.
Evaluate the expressions. Write your answer as a single base with a positive exponent.
