Answer:
D. the absolute deviation is 3
Step-by-step explanation:
Given:
data = [7,10,10,14,14,17]mean = 12MAD:
[tex]\displaystyle \large{\dfrac{1}{n}\sum_{i=1}^{n}|x_i-m| = \dfrac{|x_1-m|+|x_2-m|+|x_3-m|+...+|x_n-m|}{n}}[/tex]
Therefore:
[tex]\displaystyle \large{MAD=\dfrac{|7-12|+|10-12|+|10-12|+|14-12|+|14-12|+|17-12|}{6}}\\\displaystyle \large{MAD=\dfrac{5+2+2+2+2+5}{6}}\\\displaystyle \large{MAD=\dfrac{18}{6}}\\\displaystyle \large{MAD = 3}[/tex]
Therefore, absolute deviation is 3

A true or false test has 5 questions. what is the probability of guessing the correct answers to all the questions?
Answer:
C) [tex]\frac{1}{32}[/tex]
Step-by-step explanation:
There are only two options: right or wrong.
Right for each question: [tex]\frac{1}{2}[/tex]
Since there are 5 questions, and 5 right answers are desired: [tex]\frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2}[/tex]
= [tex]\frac{1}{32}[/tex]

At the garden store, pots were $5 and buckets were $7
If a customer bought $1140 worth of 192 pots and buckets
How many of each type did they buy?
Step-by-step explanation:
Let the number of Pots be x.
Number of Buckets be y.
From given data we have,
Customer Bought $1140 worth of 192 poys and Buckets.
Total Items=192
[tex]x + y = 192[/tex] ----------->1
Total Cost=$1140
Cost of each Pot=$5.
Cost of each Bucket=$7
Therefore we get
[tex]5x + 7y = 1140[/tex] --------->2
Solving equations 1 and 2
Equation 2 - 5×(Equation 1)
5x+7y=1140
- 5x+5y=960
-----------------------
0+ 2y=180
-----------------------
2y=180
y=90
From Equation 1 we get,
x+y=192
x+90=192
x=192-90=102
Hence we get
x=102
y=90
Therefore
Number of pots=102
Number of Buckets=90
In the morning, the temperature is "-5'F." The temperature increases by 13'F, then decrease by 5'F. Write an equation to represent the situation.
The equation to represent the temperatures are A = ( -5F ) + ( 13F ) - ( 5F )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the initial temperature in the morning be a = -5F
Now , the increase in temperature is b = 13F
And , the decrease in temperature is c = -5F
On simplifying the equation , we get
A = a + b + c
A = ( -5F ) + ( 13F ) - ( 5F )
Therefore , the value of A is ( -5F ) + ( 13F ) - ( 5F ) = 3F
Hence , the equation is A = ( -5F ) + ( 13F ) - ( 5F )

A student claims that 50% of a sample of data is less than the median and 50% of data is greater than the median, therefore the data is symmetric. What is the student's error?
a) The student did not make an error
b) It is impossible for 50% of the data values to be both less than and greater than the median, so you can't determine whether or not the data is symmetric.
c) While 50% of the data values are always greater than the median, the data may have greater variability on one side of the median than the other.
d) Data is never symmetric, so this assumption is incorrect.
Answer:
A
Step-by-step explanation:
Simply put if it's 50-50 then it just is what it is
The student's error is that d) Data is never symmetric, so this assumption is incorrect.
What is Median?Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order.
Given that,
A student claims that 50% of a sample of data is less than the median and 50% of data is greater than the median, therefore the data is symmetric.
In a symmetric distribution, the left hand side and the right hand side of the median will be equal.
That is, the left points and the right points are equal.
Hence the correct option is d) Data is never symmetric, so this assumption is incorrect.

Answer the question in the screenshot
Answer:
A. 29
B. 22
C. 36
Step-by-step explanation:
To find the median, you have to put the numbers in order from least to greatest which would be 18, 19, 22, 28, 28, 30, 32, 36, 37, 42. Then you find the number in the middle, and there are 10 numbers. So, you split them in half and 18, 19, 22, 28, 28 would be on one half, and 30, 32, 36, 37, 42 would be on the second half. The middle of 28 and 30 is 29, so that is your median.
To find the lower quartile, you have to divide the numbers into two sides with the lowest numbers on one side and the highest numbers on the other. Since there are 10 numbers, there will be 5 on each side. On the lowest number side there will be 18, 19, 22, 28, 28. To find the lower quartile, you find the middle number of the 5 numbers. 22 is in the middle, so that is the lower quartile.
To find the upper quartile, you have to take the highest numbers which are 30, 32, 36, 37, 42. Then you find the middle number, just like finding the lower quartile. The number in the middle is 36, so that is the upper quartile.

Step-by-step explanation:
for the rectangle the formula is bxh (base x height). for a triangle, it is bxh/2, or base times height divided by 2. for a trapezoid, it is b1+b2 x h / 2, or base 1 (bottom) plus base 2 (top) times height, take all of that and divide by 2.
