Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others. From this definition,
For sample 1, Every fifth person who enters Little Casesars Arena for a Red Wings game. This is not biased because no person is more likely to be selected than another
For sample 2, Every tenth name in the phone. This is also not biased
because no person is more likely to be selected than another
Answer:
Step-by-step explanation:
step 1
Find out the lateral area of the pillars
we know that
The lateral area of a rectangular prism is equal to
where
P is the perimeter of the base
H is the height of the prism
Determine the perimeter of the base
----> is a square base
The lateral area is equal to
Remember that the number of pillars is 2
so
step 2
Find the cost of tiling the pillars at the rate of Rs 52 per square feet
Multiply the lateral area of the two pillars by the rate
so
Answer:
absolute max=
(4.243,18)
absolute min =(-1,-5.916)
absolute max=(pi/6, 2.598)
absolute min = (pi/2,0)
Step-by-step explanation:
a)
To find max and minima in the given interval let us take log and differentiate
It is sufficient to find max or min of Y
In the given interval only 4.243 lies
And we find this is maximum hence maximum at (4.243,18)
Minimum value is only when x = -1 i.e. -5.916
b)
Equate I derivative to 0
-2sint +1-2sin^2 t=0
sint = 1/2 only satisfies I quadrant.
So when t = pi/6 we have maximum
Minimum is absolute mini in the interval i.e. (pi/2,0)
