Step-by-step explanation:
Sounds like you're more interested in being given answers than you are in receiving help and guidance towards finding your own answers.
I will give you one answer and ask you to find the other two.
First, rearrange the given data 3 2 6 4 5 3 4 2 7 5 3 in ascending order. Since you have 11 data points, merely choose the point in the exact middle (that is, the 6th point). That's your "median" for this data set.
Your turn: look up "mean" and share the definition you find. Do the same for "mode."
Supposing you sum up the 11 data points and divide that sum by 11. What would this give you? What's its name?
Answer:
Option B. 7.6
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
where
k is the constant of proportionality
The slope of the linear equation is the same that the constant of proportionality
In this problem we have
so
the slope is 
therefore
The constant of proportionality k is 
The height is 3 feet long
you multiply 5 by 4 and get 20 and 20x3=60 therefore 3 is your answer
First, you should substitute the variables for their value in the expression.
= [ 3 (-0.5) (4)² - (-3) ] / (-0.5)
= [ 3 (-0.5) (4)² + 3 ] / (-0.5)
= [ 3 (-0.5) (16) + 3 ] / (-0.5)
= [ (-1.5) (16) + 3 ] / (-0.5)
= [ (-1.5) (16) + 3 ] / (-0.5)
= (-24+3) / (-0.5)
= -21 / -0.5
= 42
