Answer:
x = 1+sqrt(69)/8 about 2.0383
or
x = 1-sqrt(69)/8 about -0.0383
Step-by-step explanation:
Use the quadratic formula:
(Move 17 to the left side first though)
(-b±√(b²-4ac))/2a
(1±sqrt(1-4*1*-17))/2(4)
x = 1±sqrt(69)/8
The most efficient method is the quadratic equation because the equation is not easily factorable and a!=1.
Answer:
d. 30
Step-by-step explanation:
The computation of the 35th percentile of this data set is shown below:
Before that first we have to series the number in ascending number
S. No Numbers
1 26
2 29
3 30
4 30
5 31
6 32
7 34
8 35
9 36
Now use the formula
Here n = 9
Percentile = 100
= 3.5th
= 3th + 0.5 (4th - 3th)
= 3th + 0.5 (30 - 30)
= 3th + 0
= 30
