Answer:
The salmon size is less than equal to 10.28 inches represent bottom 25% of all salmon.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 12.5 inches
Standard Deviation, σ = 3.3
We are given that the distribution of salmon size is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.25
Calculation the value from standard normal z table, we have,
Thus, the salmon size is equal to or less than 10.28 inches, they are considered small and young and represent bottom 25% of all salmon.
Answer:
area of the rectangle is 168 inch²
area of triangle:
→ * base * height
→ * 2 * 12
→ 12 inch²
area of left triangle is 12 inch² and right triangle is 12 inch²
Both triangle have same area; so total area of both: 2 * 12 = 24 inch²
Area of the trapezoid: area of the rectangle + area of two triangles
→ 168 inch² + 24 inch²
→ 192 inch²
