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%.

Answer:
D
Step-by-step explanation:
Use law of sines
320ft/sin(17) = x ft/sin(128)
x = 862.5
Find 17 degrees using 180 - 128 - 35 = 17
The probability would be 50 percent because there are 3 gold watches and 3 silver watches.
