The answer is b because 80+60=140, -7 and then divide by three you get 11
Answer:
Unsimplified: 28/40 people passed
Simplified: 7/10 people passed
Step-by-step explanation:
28/40 passed now we simplify it, divide both sides by two
28/4=7
40/4=10
7/10
Answer:
no
Step-by-step explanation:
If this were a right triangle we would assume the Pythagorean Theorem to prove it


this gives us
49+64=84.64
this is 143=84.64 and therefore not equal and not a right triangle
Average rate of change is 0
Interpretation: The crop yield did not change from year 5 to year 15
<em><u>Solution:</u></em>
The function that models the yield is:

The average rate of change of f(x) from x = a to x = b is given by the formula:

Find and interpret the average rate of change from year 5 to year 15


<em><u>Thus average rate of change:</u></em>


Thus Average rate of change is 0
Interpretation: The crop yield did not change from year 5 to year 15.
