Answer:
25th percentile = 202
80th percentile = 285

N = total number of variables = 15.
25th percentile = [(N + 1)/4]th variable = (15 + 1)/4 = 4th variable.
So, the 25th percentile = 4th variable = 202.
80th percentile = 0.8(N + 1) th variable = 0.8 × (15 + 1) = 12.8th variable = 13th variable = 285
To find the 25th and 80th percentiles for the reaction times, sort the list and determine the corresponding values.
To find the 25th and 80th percentiles for the reaction times in this experiment, we need to first sort the list in ascending order:
The 25th percentile is the value that separates the lowest 25% of the data. In this case, it is the 4th value in the sorted list, which is 202 milliseconds. The 80th percentile is the value that separates the lowest 80% of the data. In this case, it is the 12th value in the sorted list, which is 273 milliseconds.

Answer:
14 to the 10th power
Step-by-step explanation:
If two exponents have the same base, you can subtract them if they're being divided.
In your case:
14 to the 15th power/14 to the 5th power
We can subtract:
15 - 5 = 10
So our final answer would be:
14 to the 10th power
(the fourth answer)

Answer:
14¹⁰
Step-by-step explanation:
14¹⁵ divided by 14⁵ equals 14¹⁰
Answer:
6.8
Step-by-step explanation:
27 / 4 = 6.75, which rounded to the nearest tenth, is 6.8.
It's incorrect. There are 6 moles of NaBr produced for every 3 moles of Na₂S among the reactants (as well as 2 moles of FeBr₃), so the mole ratio of NaBr to Na₂S should be 2 : 1, not 1 : 1.
Answer:
x<-7
Step-by-step explanation:
Use inverse operations to solve
4 - ( x + 2 ) < -3 ( x+ 4)
first distribute the (-) sign and the (-3)
4 -x -2 < -3x -12
simplify
2 -x < -3x -12
simplify again, with inverse operations
2 -x < -3x -12
+3x +3x
2 + 2x < -12
-2 -2
2x < -14
/2 /2
x<-7
in 4 - (x + 2) < -3(x + 4), x < -7
isolate the variable by dividing each side by factors that don't contain the variable.
