Step-by-step explanation:
1) Find the Mean of all the numbers.
3+4+5+7+10+12+15=56
56/7=8 mean is 8
Now We Calculate Standard Deviation:
S=[tex]\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}[/tex]
You take each number from the problem i.e 3,4,5...
and then you subtract the mean from it and then square it.
S=[tex]\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}[/tex]
S=[tex]\sqrt{25+16+9+1+4+16+49}[/tex]
S=[tex]\sqrt{120}[/tex]
S=[tex]\sqrt{120}/7[/tex]
7 is the amount of data units given in the problem.
120/7=17.1428571429
[tex]\sqrt{17.1428571429}[/tex] =4.1403933560541

Answer:
[tex]\frac{2}{3}[/tex] (9 + 12) > 15 * [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3}[/tex] (9 + 12) = [tex]\frac{2}{3}[/tex] * 21 = 2 * 7 = 14
15 * [tex]\frac{2}{3}[/tex] = 5 * 2 = 10
14 > 10 ⇒ [tex]\frac{2}{3}[/tex] (9 + 12) > 15 * [tex]\frac{2}{3}[/tex]

The figure of y = x will be a straight line with slope 1 and they ;lie in the first quadrant and the third quadrant.
What is Linear Function?A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables but does not have exponents to the variables or the exponent of the variable is 1.
We have to choose 5 ordered pairs first whose first and second coordinate are equal.
Let the coordinates be (-4, -4), (-2, -2), (0, 0), (2, 2) and (4, 4).
The ordered pairs are of the form (x, x), that both the coordinates have same value.
So we get a linear function y = x
The graph of a linear function will be a straight line.
Since y = x, the graph will be a straight line which tends to the positive direction and the slope of the line = 1.
That is , the angle that the line making with the X axis is 45°.
And the figure lies on first and third quadrant.
Hence the figure of y = x would be a straight line with slope 1.

Tim has a friend, John, across the world he wants to transfer 1000$ to. However, his bank charges a 0.3% fee on the value of every transfer. Tim wants John to receive 1000$ after the fees, which means that Tim needs to send more than 1000$ for him to cover the fees the bank charges. How much should Tim send so that John receives 1000$ in his account after fees?
Answer:

What are the dependent and independent
variables?
Answer:
The dependent variable depends on the value of some other number also known as the independent variable. Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5.

For example, the January sales from last year are compared to the January sales from this year. Which of the following best describes the first step needed to simulate this data?
(Answer choices shown in photo. Will report fake/spam answers. Thanks for the help).
Answer:
Determine the proportion of months where memberships sold decreases,
increases and remained the same.
Step-by-step explanation:
I just took the test and got it correct.
The first step needed to simulate this data is:
Assign each month a digit from 1 to 24 to account for the 24 total months being compared.
Option B is the correct answer.
What is simulating data?Simulating data means creating artificial data that mimics the characteristics of real data.
This artificial data is generated by using a model or a set of rules that describe how the data might be generated under certain conditions.
We have,
The first step needed to simulate this data is to assign each month a digit from 1 to 24 to account for the 24 total months being compared.
This will allow for an easy comparison of the sales data from last year and this year.
Once each month has been assigned a digit, the data can be organized and analyzed to determine the proportion of months where memberships sold decreased, increased, and remained the same, as well as the mean monthly sales from last year and this year.
Finally, random digits can be assigned to each sales figure from last year and this year to create a simulated data set that can be used for further analysis and modeling.
Thus,
