Find the mean absolute deviation for this data set.
2, 3, 1, 5, 4
The mean absolute deviation of the given data set is 1.2.
How to calculate the mean absolute deviation of a data set?Mean absolute deviation (MAD) is a measure of the average absolute distance between each data value and the mean of a data set. The formula for MAD is:
MAD =∑|x-m| / n
∑ is known as Sigma and means to sum up
| | are vertical bars that mean absolute value
x is each value
m is the mean
n is the total number of data points in your data set
Given: 2, 3, 1, 5, 4
n = 5
m = 2 + 3 + 1 + 5 + 4 = 15/5 = 3
∑|x-m| = |2-3| + |3-3| + |1-3| + |5-3| + |4-3| = 6
MAD =∑|x-m|/n = 6/5 = 1.2
Therefore, the mean absolute deviation of the set data is 1.2

(This question is about trigonometric ratios)
9514 1404 393
Answer:
(b) 15.32
Step-by-step explanation:
You can use your triangle sense to answer this.
The side x will always be shorter than the hypotenuse, 20. This eliminates the last two choices.
If the angle is 45°, then the sides are equal at about 0.707 times the length of the hypotenuse. That would make them 0.707×20 = 14.14. Since the angle is greater than 45°, the opposite side will be greater than 14.14. Only one answer choice fits between 14 and 20: the second choice -- 15.32.
__
The mnemonic SOH CAH TOA reminds you of the relation ...
Sin = Opposite/Hypotenuse
sin(50°) = x/20
x = 20×sin(50°) . . . . multiply by 20 to find x
x ≈ 15.32 . . . . . . . . . use your calculator to evaluate

The attachment is intended to show how the triangle side lengths change with angle.

Out of a total of 125 students surveyed, 48 said they did not like ice cream. Out of the total number of students surveyed, what percent said they did like ice cream?
Answer:
62% said they like ice cream
The percentage of students who liked the ice cream is given by the equation A = 61.6 %
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the percentage of students who liked ice cream be A
Now , the equation will be
The total number of students = 125 students
The number of students who didn't like ice cream = 48 students
The number of students who liked ice cream = 125 - 48
The number of students who liked ice cream = 77 students
So ,
The percentage of students who liked ice cream A = ( number of students who liked ice cream / total number of students ) x 100
Substituting the values in the equation , we get
The percentage of students who liked ice cream A = ( 77/125 ) x 100
On simplifying the equation , we get
The percentage of students who liked ice cream A = 0.616 x 100
The percentage of students who liked ice cream A = 61.6 %
Therefore , the value of A is 61.6 %
Hence , the percentage is A = 61.6 %

Answer: The answer is A
Step-by-step explanation:
Answer:
The answer is 34.6, or A.
Step-by-step explanation:
The formula for area is pi*r*r. This means that you will have to take the area, or A, and do this: [tex]\sqrt{\frac{a}{pi} }[/tex]. That would be that radius, so then multiply that by 2*pi, and that would give an answer of approximately 34.6.
The graph of a cosine function is shown. Which two points on the midline of the function are separated by a distance of one period?
Answer: (pi/8, 1) and (5*pi/8, 1)
Step-by-step explanation:
First, the midline is a horizontal line that cuts the graph in two halves.
In this case, we can see that the maximum of the function is y = 2.5, and the minimum is y = -0.5
The difference is:
Diff = (2.5 - (-0.5)) = 3
If we subtract half of the difference (3/2 = 1.5) to the maximum, we get the midline.
Then:
midline: y = 2.5 - (3/2) = 1
the midline is the line y = 1
Now, a period T is such that:
Sin(x) = Sin(x + T)
Two points that are in the midline and that are separated by a period will be two points on the line y = 1, and that are in corresponding parts of the graph.
Here the two points are, counting from left to right, the third and the 11th.
(both of them are in the line y = -1 and in the negative slope part).
The points are:
(pi/8, 1) and (5*pi/8, 1)

Angel uses 1/8 cup of sugar for 1/3 of a recipe. How much sugar is needed if Angel makes the entire recipe twice?
Answer:
3/4 cups of sugar
Step-by-step explanation:
So we know that 1/8 cup of sugar is for 1/3 OF a recipe.
So if we want the full recipe we jsut have to multiply 1/8 by 3 since its only worth 1/3 of the recipe.
You’ll get 3/8 cups of sugar for a whole recipe. The question asks for 2 full recipes and since we already know it takes 3/8 cups for one we can multiply that by 2 to find the amount of sugar needed for 2 full recipes.
You’d get 6/8 cups of sugar.

Answer:

Step-by-step explanation:
Hello There!
The shown figure is a trapezoid with the following dimensions:
Height - 11m
Base 1 - 41m
Base 2 - 19m
Given this information we need to find the area
Remember the formula for the area of a trapezoid is
[tex]A=\frac{a+b}{2} h[/tex]
where a and b are bases and h is the height
Because we are given all of the information needed to calculate the area all we have to do is plug in the values into the formula
So...
[tex]A=\frac{19+41}{2} 11\\19+41=60\\\frac{60}{2} =30\\30*11=330\\A=330[/tex]
In conclusion the area of the figure is 330 square units
Write an equation that describes the function.
