The interquartile range for the given data set 2.35, 1.56, 1.77, 2.45, 6.02, 4.38, 2.77, 5.23, 2.22, 3.26 is 2.16.
What is meant by interquartile range?The middle two-thirds of your data set—the interquartile range, or IQR—contain the second and third quartiles. The interquartile range, as opposed to range, provides the range of the middle half of a data set. Range provides the spread of the entire data set. The statistical dispersion, or spread of the data, is measured in descriptive statistics by the interquartile range. In addition to the IQR, other names for it include the mid spread, middle 50%, fourth spread, and H-spread. The distinction between the data's 75th and 25th percentiles is what is meant by this term.
Given the data set is,
2.35, 1.56, 1.77, 2.45, 6.02, 4.38, 2.77, 5.23, 2.22, 3.26
First we have to arrange data set in the ascending order:
1.56, 1.77, 2.22, 2.35, 2.45, 2.77, 3.26, 4.38, 5.23, 6.02
Here,
Median=(2.45+2.77)/2
Median=2.61
First Quartile Q₁=2.22
Third Quartile Q₃=4.38
Interquartile Range= Q₃- Q₁
=4.38-2.22

Find the demand function for the marginal revenue function. recall that if no items are sold, the revenue is 0.

Answers
The marginal revenue function, locate the demand function is P = 0.02x² -0.025x + 138 when R'(x) = 0.06x² - 0.05x + 138 .
Given that,
We have to find for the marginal revenue function, locate the demand function.
Remember that the income is zero if no things are sold:
R'(x) = 0.06x² - 0.05x + 138
p(x) is what.
We know that,
MR = dTR/dx = 0.06x² - 0.05x + 138
Integrating the marginal revenue function , we get total revenue function,
MR = TR
= (0.06x²⁺¹)/(2+1) - (0.05x¹⁺¹)/(1+1) + 138x
= (0.06x³)/3 - (0.05x²)/2 + 138 x
TR = 0.02 x³ - 0.025 x² + 138 x
TR = (P)(Q) = (P)(x) = 0.02 x³ - 0.025 x² + 138 x
P = ( 0.02 x³ - 0.025 x² + 138 x)/x
P = 0.02x² -0.025x + 138
Therefore, The marginal revenue function, locate the demand function is P = 0.02x² -0.025x + 138 when R'(x) = 0.06x² - 0.05x + 138 .

If the scale of drawing is 1 inches : 250 inche and the real horse height is 15 inche, then the height of the horse in drawing is 0.06 inches.
What does a scale look like in math?The ratio that describes the relationship between the true figure itself and model is called the scale. It serves as a representation of the real statistics in smaller units on maps. A scale of 1:5, for instance, indicates that 1 on the map is approximately the size of 5 in the actual world.
Briefing:The scale of drawing the horse = 1 inch :
Therefore in scale
Horse height in drawing equals one inch
The height of the horse = 250 inche
The original height of the horse = 15 inche
The height in the picture = x inches
To find the height the horse in the picture, we have to use proportion
1 inch : 250 inche = x inches : 15 inche
1 / 250 = x / 15
1 × 15= 250x
250x = 15
x = 15/250
x = 0.06 inches
Therefore, the height of the horse in drawing is 0.06 inches

Cadence has a collection of 52 dolls that all have either blue-eyes or green-eyes. Cadence has 16 more blue-eyed dolls than green-eyed dolls. How many green-eyed dolls does Cadence have? How many blue-eyed dolls?
Answers
Answer:
18 green eyed dolls and 34 blue eyed dolls
Step-by-step explanation:
Cadence has a total of 52 dolls, either green eyed or blue eyed so lets take the number of green eyed dolls as g and the number of blue eyed dolls as b. So you have
b + g = 52
also we know b is 16 greater than g so
b - 16 = g
transpose 16 & g
b - g = 16
Now we add the equations
b+g = 52
b-g = 16
______
2b = 68
(+g and -g cancel each other out)
so b = 34
If we put 34 into an earlier equation
34 + g = 52
g = 52 - 34
g= 18

For example, if two legs of a right-angled triangle are given as 4 units and 6 units, then the hypotenuse (the third side) can be calculated using the formula, c2 = a2 + b2; where 'c' is the hypotenuse and 'a' and 'b' are the two legs.where a and b are legs and c is the hypotenuse
we are given one leg (OP=8) and the hypotenuse (ON=18) so now we can plug in these numbers to find PN

b²=260
b=√260
b=√4 * √65
b=2√65

Answers
Answer:
To solve a quadratic equation using the method of completing the square, we need to first write the equation in the form ax² + bx + c = 0, where a, b, and c are constants. In this case, the given equation is 2²+3x+37 = 0, which can be written as 4+3x+37 = 0.
To complete the square, we need to add a number to the constant term (in this case, 37) so that the coefficient of the x² term is a perfect square. In this case, the coefficient of the x² term is 4, which is already a perfect square. Therefore, we do not need to add any number to complete the square.

What is the mean and the range?A dataset's mean is the sum of all values divided by the total number of values. It is the most widely used measure of central tendency and is frequently referred to as the "average."
The range of a set of numbers is the difference between its highest and lowest values. To find it, subtract the lowest value from the highest in the distribution.
The given data is 45,68,77,90,90,95,100,100,86,90,50,55.
The mean of the data will be calculated as,
Mean = (sum of the data) / ( number of the data)
Mean = ( 45 + 68 + 77 + 90 + 90 + 95 + 100 + 100 + 86 + 90 + 50 + 55)/12
Mean = 94.6
The range of the data will be calculated as,
Range = Highest value - The lowest value
Range = 100 - 45
Range = 55
The mode of the data is 90 because it has three repetitions.
The median of the data is the middlemost value of the data when the data is arranged in increasing order,

There are three branch prediction scheme: predict not taken, predict taken, and dynamic prediction. assume that they all have zero penalty when they predict correctly and two cycles when they are wrong.
In computer architecture, a branch predictor is a digital circuit that attempts to guess which direction a branch (e.g. an if-then-else construct) is going finally announced. The purpose of the branch predictor is to improve the flow of the instruction pipeline. Branch predictors play a key role in achieving high performance in many modern pipeline microprocessor architectures.
1. If the branch is taken 5% of the time, the branch prediction scheme is ``predicted-taken'' because the process must start fetching and then executing at the target address.
2. If a branch is taken 95% of the time, the branch outcome is known with certainty, so the branch prediction scheme is "unpredictable".
3. If the branch is taken 70% of the time, then the prediction scheme is "dynamic prediction" and the branch prediction can change dynamically during program execution.

Answer:
The correct answer is B. looking for work/total work force.
Unemployment rates are typically calculated by dividing the number of people who are looking for work by the total work force. The work force includes all people who are currently employed or actively looking for work, regardless of whether they are currently employed. The number of people who are looking for work is determined by surveying individuals and asking them whether they are currently seeking employment. The unemployment rate is then calculated by dividing the number of people who are looking for work by the total work force, and expressing this as a percentage.
The other answer choices are not accurate ways of calculating unemployment rates. Dividing the total work force by the number of layoffs (A) would not give an accurate measure of unemployment, as it would not account for people who are looking for work but have not been laid off. Dividing the number of people looking for work by the total population (C) would also not be an accurate way of calculating unemployment, as it would not take into account people who are not part of the work force (e.g. children, retirees, etc.). Therefore, the correct method for calculating unemployment rates is to divide the number of people looking for work by the total work force.

How do you graph a rational function example?
Answers
To graph a rational function example, start by writing the equation in the form y = (ax + b)/(cx + d).
Then, plot the points where the denominator equals zero (when x = -d/c). These points are called vertical asymptotes.Next, plot the points where the numerator equals zero (when x = -b/a). These are called horizontal asymptotes.Finally, plot points between the vertical and horizontal asymptotes to graph the rational function.Plotting the points between the vertical and horizontal asymptotes will allow you to see the shape of the graph. Start by plotting points on either side of the vertical and horizontal asymptotes. Then, plot points at evenly spaced x-values between the vertical and horizontal asymptotes. For example, if the vertical asymptote is at x=-d/c, and the horizontal asymptote is at x=-b/a, you can plot points at x=-1.5d/c, x=-0.5d/c, x=-1.5b/a, and x=-0.5b/a. By plotting these points and connecting them with a smooth curve, you can graph the rational function.
