Answer:
slope is -3/2
Step-by-step explanation:
Use the slope formula
y2-y1/x2-x1=m (rise over run)
(7,5) (5,8)
x1 y1 x2 y2
8-5/5-7=m
-(3/2)=m
Times by 3. Then divide the top backup by 3 to get 9/30. 9/30+9/30+9/30=27/30=9/10.
Answer:
Sorry it's acually (h+3)(h-9)
Based on the estimated number of defective batteries and the number of batteries that were actually defective, the percent error of Jake's estimate is 20%
<h3>How to find the percent error?</h3>
The percent error of a problem can be found by the formula:
= (Expected results - Actual results) / 100%
Expected results = 12 defective batteries
Actual results = 10 defective batteries
Jake's percentage error is therefore:
= (12 - 10) / 100%
= 2 / 10 x 100%
= 0.2 x 100%
= 20%
In conclusion, the percent error of Jake's estimate is 20%.
