You are a chief for an electric utility company. The employees in your section cut down trees, climb poles, and splice wire. You report that of the 128 employees in your department 10 cannot do any of the three (management trainees), 25 can cut trees and climb poles only, 31 can cut trees and splice wire, but not climb poles, 18 can do all three, 4 can cut trees only, 3 can splice wire, but cannot cut trees or climb poles, and 9 can do exactly one of the three. How many employees can do at least two of the three jobs mentioned?

109 Employees

Step-by-step explanation:

Total Number of Employees, Universal Set=128

Key: P=Climb poles, T=Cut down trees, W=Splice wire

Since 9 can do exactly one of the three.

Number of Employees who can do at least two of the jobs

109 Employees can do at least two of the jobs.

OR

Therefore: Number who can do at least two jobs

=128-(10+9)=109

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

it would be a on edgenuit y
