Write a fraction that is less than 5/6 and has a denominator of 8
KatRina [158]
You'll want to make a common denominator with 6 and 8.
That denominator would be 24.
24/6=4 so you would have to multiply 5/6 by 4/4 to get 20/24.
Next, 24/8=3 so 1/8 could be multiplied by 3/3 to get 3/24.
Since 3 is less than 20, 1/8 is smaller than 5/6.

If you want the same numerator, 5/8 = 15/24. This would make 5/8 smaller than 5/6 as well.
The highest eighth you can go is 6/8 which is 18/24.
So you can use any numerator between 1 and 6 with a denominator of 8 to get a fraction smaller than 5/6.

Any one know how to find the roots of an equation?
soldier1979 [14.2K]
So what you do is
make into ax^2+bx+c=0 form

add-9/2 to both sides
y^2-2y+9/2=0
now we use the quadratice formula which is
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}

ax^2+bx+c=0
1y^2-2y+9/2
a=1
b=-2
c=9/2
subsitute
x=\frac{-(-2)+/- \sqrt{(-2)^{2}-4(1)(9/2)} }{2(1)}
x=\frac{2+/- \sqrt{4-(36/2)} }{2}
x=\frac{2+/- \sqrt{4-(18)} }{2}
x=\frac{2+/- \sqrt{-14} }{2}
x=\frac{2+/- \sqrt{-14} }{2}
x=1+/- \frac{\sqrt{-14} }{2}
x=1+/- \frac{\sqrt{14} \sqrt{-1}}{2}
x=1+/- \frac{\sqrt{14} i }{2}
x=1+/- \frac{ i \sqrt{14} }{2}

answer is C

marusya05 [52]

Answer:

Stratified Sampling

Step-by-step explanation:

Since Keri divides the day into different strata and each unit is selected from each strata randomly. So, it is Stratified Sampling.

Further, In Stratified Sampling population is divided into several groups such that within the group it is homogeneous and between the group it is heterogeneous. And now a selection of each stratum and unit has an equal chance of selection.
