Answer:

Mean = 7

Step-by-step explanation:

Given

Data: 2, 4, 6, 12, 8, 10.

Required

Determine the mean

The mean of a data is calculated as thus:

Mean = \frac{\sum x}{n}

In this case:

n = 6

So, the formula becomes:

Mean = \frac{2+4+6+12+8+10}{6}

Mean = \frac{42}{6}

Mean = 7

How do I solve 6x—20=
REY [17]

Answer:

Can not be determined

Step-by-step explanation:

regularly, you would +20 to both sides, but without a full =, you cant solve. If the equation is 6x-20=0, x would equal 3 2/6.

Hope this helps!

kenny6666 [7]
Assuming its the same temp, use this equation for pounds and minutes then solve:

\frac{1}{3.5} =  \frac{50}{x}

cross multiply 

50(3.5) = 175 minutes 

it'll take an 2 hours 55  minutes

Write a compound inequality: a quantity of x is greater than 10 and less than 20
Rudiy27

The compound inequality is: x<20 and x>10

Given,  a quantity of x is greater than 10 and less than 20.

A compound inequality (also known as a compounded inequality) is created when two or more inequalities are coupled with and. One part of an inequality must be true for a value to be a solution to an or inequality. It must make both parts true in order to be the solution to an inequality. X<3 or X>2, for instance.

Divide a compound inequality into two independent ones before attempting to solve it. Choose either a union of sets ("or") and an intersection of sets as the appropriate response ("and"). Then, resolve the graph and all inequalities.

Simply put, a compound inequality is more than one inequality that we want to address simultaneously. When referring to the resolution of both inequalities, we can either use the term "and" or "or."

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function?
gogolik [260]

Answer:  If you plot a point in the y-axis at -6, you can plot two more points by using the slope "rise over run" Then draw a line connecting the points.

The coordinate of the y intercept is (0.-6)  To find the first x values of the first 2 coordinates, add 1 then 2 to 0. To find the y values, add 2 then 4 to the -6

Step-by-step explanation:

From -6 go up 2 over 1 and plot at (1, -4 )  then up 2 over 1 again to (2, -2)

The x- intercept will be at  (3,0)
