Answer:
31/40
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
Number of possible outcomes = 270, number of total outcomes = 1200
Probability (the number of people from the suburbs attending the concert is 270) = 270/1200 = 9/40
Probability (the number of people from the suburbs attending the concert is fewer than 270) means that the number of people from the suburbs attending the concert is not 270 = 1 - 9/40 = (40-9)/9 = 31/40

Explanation:
The quadrilateral will be a parallelogram if the diagonals bisect each other. That will be the case if the sums of their end-point coordinates are the same.
A + C = (-3, 6) +(9, -9) = (6, -3)
B + D = (6, 0) +(0, -3) = (6, -3)
Both diagonals have their midpoint at (3, -1.5), so the diagonals are mutual bisectors. The figure ABCD must be a parallelogram.
___
The midpoint of AC is (A+C)/2 = (6, -3)/2 = (3, -1.5).
A spinner is divided into eight equal-sized
sections, numbered from 1 to 8, inclusive. what
is true about spinning the spinner one
Answer: B.
First, we have to have a question for this problem to create a solution. So, the example sentence is how many granola bars does each student get.
Second, an algebraic expression has a variable in it. So since we are trying to find the number of students, the variable is s.
From looking at C and D, we can already eliminate them. This question has mostly multiplication and division words in it, so it can't be addition and multiplication.
Now, we only have A and B left. A tip on how to figure this out is reading the word problem out thoroughly. I will use B as an example. 5 boxes of granola bars were multiplied by the number of granola bars each student got. From reading this, it makes more sense. But it does change the example sentence, though.
I hope this helped and this is the right answer!
Answer:
I think it is 20.75°
Step-by-step explanation:
An interesting problem!
the m arcVYX = 282° so the m arcVYXV must equal 360°
so the m arcVX must equal 360 - 282 = 78°
I beleive m angle UVX - m arcVX = 78°
78 = 4x - 5
83 = 4x
20.75° = x
I don't like this answer. I would normally exspect whole numbers for most algebra problems
