The 98% confidence interval ranges from 48.60 to 51.40 hours.
Please research the included formula below, as it is crucial to understanding this topic.
better late than never :P
The answer is B. Since you know the lengths of both legs of the triangle, you can use the Pythagorean Theorem to solve. The Pythagorean Theorem says "a squared plus b squared equals c squared. The square root of c is the length of the hypotenuse." Since there is no answer that says 19.799 (This is the approximate answer), then the answer is B.
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality

Answer:
A
Step-by-step explanation:
Refer to the picture.
Step 1: expand the bracket
Step 2: bring like terms together (e. G. Numbers, algebra like terms)
Step 3: simplify equation
Step 4: rearrange algebraic form to see which order fits the answer.
