Answer:
<span>533</span>
Explanation:
We first let <span>0.<span><span>¯¯¯¯</span>15</span></span> (15 being repeated) be x.
Since x has 2 decimal places recurring, we multiply it by <span>100.</span>
<span> x=0.151515....</span>
<span>100x=15.151515...</span>
Next, we subtract them.
<span><span>100x−x=15.151515−0.151515</span><span>99x=15</span></span>
Lastly, we divide both sides by 99 to get x as a fraction.
<span><span>x=<span>1599</span></span><span>=<span><span>533</span></span></span></span>
Answer:
x -7
Step-by-step explanation:
(3x + 5) + (2x - 9) - (4x+3)
3x + 5 + 2x - 9 -4x -3
x -7
Given the data
X, ...rankX.....Y.....rankY......d=rx-ry........d²
4.........4...........-5......4................0..............0
53.......3.........-1........3................0...............0
86.......2.........13.......2................0................0
162......1..........16.......1.................0...............0
Then, using the rank correlation formula
p = 1 — 6•Σd² / n(n²—1)
p = 1 - 6• 0 / 4(4²-1)
p = 1 - 0
p = 1
So, the rank correlation is 1, this means that the two variables being compared are monotonically related, even if their relationship is not linear.
Nope, because .3 becomes .30, and .30 is less than .32
