Answer:
You haven't given all the data examples as there is just one box plot.
If there are only two choices of Data then go with the first one on picture as it handles data up to 24
The first data on picture also balances the data 15, 17 and 19 and 19 as the first two quarters. So seems to draw the median at 19 and out of the two examples is more consistent to quarters 1-4 = 15-24
Step-by-step explanation:
I would look for answers that represent the whole data
1st qtr = 13-15 = 2
2nd qtr = 15-19 = 4
3rd qtr = 19- 21 = 2
4th quarter = 21-24 = 2
As 2nd qtr is twice as big it still only represents 25% data
You said that (xy) = 16, and (x+y) = 4 .
From the second equation you can get [ x = 4 - y ],
then substitude that for 'x' in the first equation, and
finally, rearrange the first equation to read
<u>x² - 4x + 16 = 0</u>
Don't even try to factor that quadratic equation. Go straight
to the quadratic formula, and the two solutions you find are ...
<em>x = 2 + i 2√3</em>
and
<em>x = 2 - i 2√3</em> .
Those are the two number that do what you want.
There are no <u>real</u> numbers that can do it.
Answer:
Step-by-step explanation:
x = last month
y = this month
y = 2x + 7
y = 43
43 = 2x + 7
43 - 7 = 2x
36 = 2x
36/2 = x
18 = x <== he sold 18 gym memberships last month
Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle is 180 degrees.
90 + 2x - 2 + x + 5 = 180 degrees.
Combine like terms.
3x + 93 = 180
Subtract 93 from both sides.
3x = 87
Divide both sides by 3
x = 29
