<h2>Solving for the Mean, Median and Mode of a Data Set</h2><h3>Answer:</h3>

Mean: 8

Median: 7

Mode: 5

<h3>Step-by-step explanation:</h3>

If we increase each element in the data set by 4, our new data set will be...

\{ 7, 9, 5, 9, 5, 5, 6, 7, 19 \}

The mean of a data set is the sum of all of its elements divided by the number of elements.

Solving for the mean:

\frac{7 +9 +5 +9 +5 +5 +6 +7 +19}{9} \\ \frac{72}{9} \\ 8

The median of a data set is just the middle number if and only if the elements of the data set is arranged according to how less to how great each element is.

If we arrange our data set it will be...

\{ 5, 5, 5, 6, 7, 7, 9, 9, 19 \}

We can do see that our middle number is 7 so this our median.

The mode of a data set is the number that repeated the most. We can see in our data set that the number 5 repeated 3 times. 6 and 19 is 1. 7 and 9 is 2. Since 5 is the number that repeated the most, this is our median.

Which of the following are point slope equations of the line going through (-3, -5) and (2, 4). Help is appreciated!​
ki77a [65]

Answer:

A and F

Step-by-step explanation:

first figure out the slope.

4-(-5)/2-(-3)= 9/5

slope: 9/5

y-y1=m(x-x1)

you substitute either coordinate for the second variables. we automatically take out any slopes that have a negative because the slope is positive.

C, D, E all have negative slopes so it is wrong.

B does not work because a negative times a negative is a positive. the equation shows it to be negative so it is wrong.

A & F fit the solution.

Alekssandra [29.7K]
Slope=0.005/2.000=0.002
p - intercept = 974/1 = 974.00000
n- intercept = 974/-404 = 487/-202 = -2.41089


Oh and it is ok if you don’t have a lot of points I am great full for the points you are giving me and the answer is C)13,094 and can I have the brainliest since the other guy clearly did not answer the question right I only have one brainliest ☺️

PLEASEHELP!

You factor out primes from the root, for example:
root 100
you can get 10 from it, or we'll use 5

100/5=20
20/5=4
root 4= 2
because there are 2 "5" we can bring that out of the root, there are 2 "2" so we bring that out too.
When a number is taking out of a root, the 2 exact same numbers become one. in this case, there are ONE 5 and ONE 2 outside the root. then You multiply 5 and 2 together, and you get 10
