The correct option regarding when each table is appropriate is given by:
E.) Z-Tables are applicable when you have population data, T-Tables are applicable when you have sample data.
<h3>When to use the z-distribution and the t-distribution?</h3>
- When we have the standard deviation for the sample, the t-distribution is used.
- When we have the standard deviation for the population, the z-distribution is used.
Hence, option E is correct.

Answer:
Obtuse
Step-by-step explanation:
The pythagorean theorem: a^2+b^2=c^2
Right triangles: a^2+b^2=c^2
Acute triangles: a^2+b^2>c^2
Obtuse triangles: a^2+b^2<c^2
8^2+14^2 ? 20^2
64+196 ? 400
260 < 400
The triangle is obtuse.
Answer:
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.
