Answer:
a) 97.37%
b) 1.31%
Step-by-step explanation:
a)
Here we want to calculate the area under the Normal curve with mean 0.52 and standard deviation 0.009 between 0.5 and 0.54
This can be easily done with a spreadsheet and we get
<em>P (0.5くV < 0.54) = 0.9737 or 97.37% </em>
(See picture 1)
b)
Here we want the area under the Normal curve with mean 0.52 and standard deviation 0.009 to the left of 0.5.
<em>P(V ≤ 0.5) = 0.0131 or 1.31% </em>
(See picture 2)
<u>Given:</u>
A triangular piece is cut out of a rectangular piece of paper to make the class banner.
<u>To find:</u>
The area of the class banner.
<u>Solution:</u>
The rectangular piece of paper is 14 inches long and inches wide.
From the given diagram, the triangle has a base length of the same 8 inches and has a height of inches long.
To determine the area of the banner, we subtract the area of the triangle from the area of the rectangle.
The area of a triangle
The area of the triangle square inches.
The area of a rectangle
The area of the rectangle square inches.
The area of the class banner square inches.
So the banner has an area of 100 square inches which is the first option.
