Answer:
The sample size should be approximately 151.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 100
Population standard deviation, σ = 15
We have to evaluate the sample size, n.
Alpha, α = 0.10
Confidence interval:
Putting the values, we get,

Thus, the sample size should be approximately 151.
What is Elevation ?
When the height of a point is its vertical distance above or below the surface of a reference plane you have selected, it is called the elevation of that point. When the height of a point is its vertical distance above or below mean sea level , it is called the altitude of the point.
Elevation is defined as the height above the ground or other surface, or a place or position of height. An example of elevation is a plane flying at 36,000 feet above the ground. An example of elevation is a pope being raised to the position of saint.

Answer:
The value of x would be 20
Step-by-step explanation:
To solve this triangle, we need to first note that all triangles have 180 degrees. So we can add these all together and set equal to 180.
40 + 3x + 4x = 180
40 + 7x = 180
7x = 140
x = 20
The cut-off point is 0.5: higher than this would be closer to 1, and lower would be closer to 0
and 3/8 is lower than 0.5: we know this because a bigger number, 4/8 is equal to 0.5
so it's closer to 0!
