This simplified is 126x so that is equivalent to this expression
There is no difficulty in this problem until you construct the figures. How can we do it is shown in the attached picture. After drawing PRST, from the point P, we can draw PMKD and later we can complete PMCT as a result. From this picture, we can see that the side of PMCT is also a. Then, the area of this square is
Well,
Emily received $40.00 and then withdrew $40.00. The final amount would be zero.
Jacoby climbed 782 feet to get to his campsite, and then descended 782 feet to get back to his car. His final change is zero.
The Eagles mad two points, but then the Bulldogs evened it out with another two points. The difference between the two scores would be the same.
Marcus ends up going down more than he goes up, so this is not a correct option.
The Ravens scored two points, but at the end the Raiders scored an additional 5 points, which set both teams to the same score.
Since there are an equal number of protons and electrons, and the protons have the same (but opposite) amount of charge as the electrons, the charges cancel each other out, leaving the atom with a neutral overall charge (0).
Let n = required random sample size.
Assume that the population standard deviation is known as σ.
Let m = sample mean.
At the 95% confidence level, the expected range is
(m - k(σ/√n), m + k(σ/√n))
where k = 1.96.
Therefore the error margin is 1.96(σ/√n).
Because the error margin is specified as 3% or 0.03, therefore
(1.96σ)/√n = 0.03
√n = (1.96σ)/0.03
n = 128.05σ²
This means that the sample size is about 128 times the population variance.
Answer:
Smallest sample size = 128.05σ², where σ = population standard deviation.
