Given the table:
x f(x)
2 6
7 3
9 5
To determine the coordinate given in the table, we have the following:
f(2) = 6
f(7) = 3
f(9) = 5
From the answer choices, the only coordinate given is:
f(5) = 9
ANSWER:
f(9) = 5
First, create a scale that includes all the numbers- that being, you can plot both the minimum and maximum values on it.
Next, draw a line of a set height (I tend to use 2 squares in my work) where the median is. Next, draw similar lines, at the same height, for the rest of the values- both quartiles and the maximum values. You can obviously do this in whatever order you like, but that's how I do it.
Next, join up the tops and bottoms of the quartiles, with the median in the middle, and connect the middles of the quartiles to their corresponding minimum or maximum values.
Voila, my friend. You have a box plot.
Answer is a :

but the markup is more than 300%
ans : a)
Answer:
7/8 x 4/1
make 1/4 a reciprocal (basically just turning the fraction upside down)
then turn the division sign into a multiplication sign and multiply across:
7/8 x 4/1 = 28/8 = 3 4/8 = 3 1/2
Answer:
y=
3x/8x+2
Step-by-step explanation:
1
2x
−
3
4y
=−2
Step 1: Multiply both sides by 4xy.
−3x+2y=−8xy
Step 2: Add 8xy to both sides.
−3x+2y+8xy=−8xy+8xy
8xy−3x+2y=0
Step 3: Add 3x to both sides.
8xy−3x+2y+3x=0+3x
8xy+2y=3x
Step 4: Factor out variable y.
y(8x+2)=3x
Step 5: Divide both sides by 8x+2.
y(8x+2)
8x+2
=
3x
8x+2
y=
3x
8x+2
Answer:
y=
3x/8x+2
