Answer:
∠3≅∠1
∠4≅∠8
∠3& ∠8 are supplementary
Step-by-step explanation:
Median is the middle number, but since there is 6 numbers.
Put them in order first
23,39,40,40,43,50
Well in middle is 40 for both sides
So to solve median for this you'd add the two middle numbers together since there is even set of numbers.
40+40 =80 then divide by 2
80÷2=40
Median = 40
*Follow This Example for any other even sets of numbers for Median*
The "line of best fit" is the result of a linear regression computation. If you have done that, you already know its equation.
If you have "eye-balled" the line into place, then you have to figure out its equation from points you read on the graph. We take a couple of the points to be ... (2001, 1700) and (2010, 2450)
The line through these points will have the equation
... y = (2450 -1700)/(2010 -2001)(x -2001) +1700
... y = (250/3)(x -2001) +1700
Putting x=2013 into this equation, we get ...
... y = (250/3)(2013 -2001) +1700
... = (250/3)(12) +1700
... y = 2700
The population is predicted to be 2700 in 2013.
_____
Had you drawn your graph with a vertical grid line at 2013, you could have read the number from the graph.
0.08 is your answer to the question
So, the multiples for 4 and 10 are...
4,8,12,16,20...
10,20,30,40,50...
So, basically LCM means least common multiple which just means that from the two numbers that you're given (4 & 10) there is one number that goes into both of them and is the smallest amount.
So for 4 and 10, the numbers that go into both of them are 20 and 40. out of both of these numbers 20 is the lowest, making it the LCM. Hopefully that helped, and if it didn't then I'm sorry. Good luck with the rest queen.
