Answer:
Area of the parallelogram is 96 .
Step-by-step explanation:
A parallelogram is a quadrilateral with parallel and equal length of opposite sides. The diagonals are perpendicular to each other.
Area of a parallelogram is given as,
Area = base x height
Thus for the given parallelogram with base 12 cm and height 8 cm, the area would be;
Area = base x height
= 12 x 8
= 96
Area = 96
The area of the parallelogram is 96 .
Answer:
C. Decreases the margin of error and hence increases the precision
Step-by-step explanation:
If we select a sample by Simple Random Sampling in a population of “infinite” size (a population so large that we do not know its size exactly), then the margin of error is given by
where
<em>Z = The Z-score corresponding to the confidence level </em>
<em>S = The estimated standard deviation of the population </em>
<em>n = the size of the sample. </em>
As we can see, since n is in the denominator of the fraction and the numerator is kept constant, the larger the sample size the smaller the margin of error, so the correct choice is:
C. Decreases the margin of error and hence increases the precision
