The standard deviations of four data sets are shown in the table below. Which
of the data sets is the most spread out?
Data set
Standard deviation
Data set A
6.06
Data set B
4.88
Data set C
5.21
Data set D
3.39
A. Data set B
B. Data set D
C. Data set C
D. Data set A
Answer: Data set A
Step-by-step explanation: It has the most
The largest deviation for this case is from the dataset C so then the answer would be Data set C.
How is standard deviation calculated?Suppose that the considered data set is
Then, its standard deviation is the positive square root of the variance of this data set.
A variance of data set is the sum of squared differences of the data values from its mean to the total count of data values.
Thus, we get:
[tex]\sigma = \sqrt{\dfrac{1}{n} \sum_{i=1}^{n} (x_i-\overline{x})^2[/tex]
And for this case we have the deviations for each dataset are given by:
[tex]s_a = 5.21\\\\s_b =4.88\\\\s_c = 6.06\\\\s_d = 3.39\\[/tex]
We need to remember that the deviation is a measure of dispersion.
For this case, if the deviation is larger then we have more spread out the distribution of interest.
And largest deviation for this case is from the dataset C so then the answer would be:
Thus, the correct answer is D. Data set C.

y = (x2 - 2x + 1)
y = (x - 1)(x - 1)
Prove that the following functions are equivalent through algebraic and numerical proof
Answer:
see below
Step-by-step explanation:
y = (x² - 2x + 1)
y = (x - 1)(x - 1)
First, recognize that the first equation is fully simplified/expanded already.
Now, we should solve for the second equation.
FOIL the expressions: first–outer–inner–last
(x - 1)(x - 1)
F: x²
O: -x
I: -x
L: 1
Combine these terms.
x² - x - x + 1
x² - 2x + 1
Notice that this equation is identical to our first equation. Therefore, the functions are equivalent.
Hope this helps!
y = (x^2 - 2x + 1)
y = (x - 1)(x - 1)
Algebraic Proof
FOIL y = (x - 1)(x - 1)
y = (x - 1) (x -1 ) = x^2 -2x + 1
Done.
Numeric Proof
Let x = 1
y = x^2 - 2x + 1
y = (1)^2 - 2(1) + 1
y = 1 - 2 + 1
y = 2 + 2
y = 0
Let x be 1 again.
y = (x - 1)(x - 1)
y = (1 - 1)(1 - 1)
y = 0
There you have it. Both equations are the same.

The amount y (in dollars) that you earn by working x hours is represented by the equation y = 9x. A) What is the slope? B) What does the slope mean? Interpret! C) How much money would you make if you worked 40 hours?
Answer:
360 dollars
Step-by-step explanation:
Equation;
y = 9x
A) What is the slope?
The slope in an equation is the coefficient of the x variable. In this question, the slope is 9.
B) What does the slope mean? Interpret!
The slope shows the relationship between the x and y values.
This means that for every single unit change of x, y changes by 9 times.
C) How much money would you make if you worked 40 hours?
x = working hours
y = Amount
y = 9 (40) = 360 dollars

[52 + (48 divided by 8)] + 17
Answer:
75
Step-by-step explanation:
48/8 = 6
6 + 52 = 58
58 + 17 = 75!
The solution to the expression [52 + (48 divided by 8)] + 17 is 75.
To solve the expression [52 + (48 divided by 8)] + 17, follow the order of operations, which is commonly remembered as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
Step 1: Evaluate the division inside the parentheses.
48 divided by 8 equals 6.
Therefore, the expression becomes:
[52 + 6] + 17
Step 2: Perform the addition inside the brackets.
52 + 6 equals 58. The expression simplifies to:
58 + 17
Step 3: Evaluate the final addition.
58 + 17 equals 75.
Therefore, the solution to the expression [52 + (48 divided by 8)] + 17 is 75.

David has a bag of coins. The bag contains 7 dimes, 2 nickels, and 6 pennies. He will randomly select 2 coins from the bag one at a time
without replacement. What is the probability that David will select a dime first and then a penny?
Answer:
7/15 for dime
6/15 for pennies
Step-by-step explanation:
7/15 because 7+2+6=15 and there are 7 dimes so 7/15.
6/15 because there are 15 coins and there are 6 pennies so 6/15.
15 is the total so 7 and 6 have to go over it.
