What is the range for this set of data? 38, 17, 55, 40 02 38 39 O 72
Answers
Answer:
38
Step-by-step explanation:
The range is the difference between the highest value and the lowest value. Here the highest value is 55 and the lowest 17. Therefore, the range is take away 17 from 55 which equals to 38
The range for this set of data is 38.
Option B is the correct answer.
What is range in a set of data?The range is a measure of dispersion or spread in a set of data.
It is defined as the difference between the largest and the smallest values in the data set.
Range provides an idea of how much the data values are spread out or dispersed.
If the range is small, it indicates that the data values are close together, while a large range indicates that the data values are spread over a wider range of values.
We have,
To find the range of a set of data, we need to subtract the smallest value from the largest value.
Here, the smallest value is 17 and the largest value is 55.
So,
The range of the data set is:
55 - 17 = 38
Thus,
The range for this set of data is 38.

Step-by-step explanation:
If a = 38 and b = 26 then the equation would be y^2/1444 + x^2/676 = 1
also just graph it or smth
The equation of the ellipse in the figure is x^2/676 + y^2/1296 = 1
How to determine the equation?The figure is an ellipse, and it has the following parameters:
Center, (h,k) = (0,0)Major radius = 36Minor radius = 26The equation of the ellipse is then calculated using:

summarize how you can find the slope of a perpendicular line.
Answers
Let’s say we have the line given in slope-intercept form (y=mx+b), y=3x+1.
We know looking at this equation that the slope of the line is 3. To find a slope that is perpendicular you need to find it’s opposite reciprocal. In the case of 3, it’s opposite would be from + to -, so -3. The reciprocal would flip the number into a fraction -3 => -1/3. So the line perpendicular would have a slope of -1/3.
Steps:
1. Determine the slope of the line
2. Switch from a positive to a negative or a negative to a positive
3. Find the reciprocal (2/5 => 5/2, 1/4 => 4)
Since "slope" tells us the angle of the line being graphed, the word "slope" is commonly used in mathematics.
Planar geometry states that all lines have slopes. Any slope can be calculated by comparing it to another line, usually the x-axis. A line's slope, or angle, in relation to that x-axis value is how steep it is.
In mathematics, slope is the proportion of the change in the y value to the change in the x value.
Two perpendicular lines have a slope such that the reciprocal of the negative slope of one line equals the slope of the other. The slope of perpendicular lines is -1 as a result.
The relationship between the slopes of parallel lines can be demonstrated using the formula m1.m2 = -1, if the slopes of the two perpendicular lines are m1, m2.
Like a fraction, a slope works by favoring the rise, up-and-down movement, over-the-run, or side-to-side movement. If a line rose up one unit for every rightward unit traveled, the slope would be a positive one.

What is the probability of tossing a coin and getting heads three times in a row?
What is the chance that the next toss will be heads? What is the chance that the next toss will be tails?
Answers
The probability of tossing 3 heads in a row is P = 0.125, and after that, because the events are independent, the probability of getting heads (or tails) still is p = 0.5
How to find the probability?Assuming that we have a fair coin, we assume that both outcomes have the same probability, so:
P(tails) = 0.5
P(heads) = 0.5
Then the probability of getting heads 3 times in a row, is the product of the probability of getting heads 3 times, this will be:
P(3 heads) = 0.5*0.5*0.5
P(3 heads) = 0.5^3
P(3 heads) = 0.125
Now, after this point, what is the probability of getting heads or tails?
Remember that each toss of the coin is independent of the previous one, so the probability of getting tails still is 0,5, and the same for the probability of getting heads.

8. Laurie graphed two lines, as shown on the right.
One line has a slope of -2 and the other has a slope of
1/2. Laurie noticed that although the slopes are
negative reciprocals of each other, the lines do not
appear to be perpendicular. Explain why this result
occurs, even though she graphed the lines correctly.
Answers
It's possible that the lines do not appear to be perpendicular, even though the slopes are negative reciprocals, because the lines may not be intersecting at 90 degrees angle,
What are the slopes of the two lines?
The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter m.
The slopes of the two lines that Laurie graphed, -2 and 1/2, are negative reciprocals of each other, which means that their product is -1.
In a Cartesian coordinate system, lines that are perpendicular to each other will have slopes that are negative reciprocals of each other, and the product of their slopes will be -1.
However, it's possible that the lines do not appear to be perpendicular, even though the slopes are negative reciprocals, because the lines may not be intersecting at 90 degrees angle.
The two lines could be skew lines that never intersect and thus cannot be perpendicular.
Another reason could be that the lines may not be in the same coordinate system or not graphed on the same set of axes.
When working with slope, we always assume that the lines are defined on a 2D Cartesian coordinate system, if that is not the case, it could cause the lines to not appear as perpendicular.
Hence, it's possible that the lines do not appear to be perpendicular, even though the slopes are negative reciprocals, because the lines may not be intersecting at 90 degrees angle, another reason could be that the lines may not be in the same coordinate system or not graphed on the same set of axes.

The total number of times social media browsers have been showed your content.
How is social media value calculated?A general, but simplified earned media value formula is: EMV = impressions x cost per 1000 impressions x adjustable variable. The adjustable variable can be anything you are looking to track like engagement or impressions.
Simplifying
22 = 2(x + 8)
Reorder the terms:
22 = 2(8 + x)
22 = (8 * 2 + x * 2)
22 = (16 + 2x)
Solving
22 = 16 + 2x
Solving for variable ‘x’.
Move all terms containing x to the left, all other terms to the right.
Add ‘-2x’ to each side of the equation.
22 + -2x = 16 + 2x + -2x
Combine like terms: 2x + -2x = 0
22 + -2x = 16 + 0
22 + -2x = 16
Add ‘-22’ to each side of the equation.
22 + -22 + -2x = 16 + -22
Combine like terms: 22 + -22 = 0
0 + -2x = 16 + -22
-2x = 16 + -22
Combine like terms: 16 + -22 = -6
-2x = -6
Divide each side by ‘-2’.

A principal of $3600 is invested at 3.5% interest, compounded annually. How much will the investment be worth after 12 years? Use the calculator provided and round your answer to the nearest dollar. X S
Answers
Answer:
$5043
Step-by-step explanation:
To find the value of the investment after 12 years, you can use the following formula:
A = P * (1 + r/n)^(nt)
Where:
A = final amount
P = principal
r = interest rate
n = number of times the interest is compounded per year
t = number of years
Plugging in the values from the problem, we get:
A = 3600 * (1 + 3.5/100)^(1*12)
Solving this equation, we get:
A = $5043.33
So, after 12 years, the investment will be worth $5043.33.
