Nik, a social worker for a county, helps county residents who are struggling with different issues. Nik logs the following hours meeting with clients (c) or doing other work (o):

Mon: 6 c, 4 o
Tue: 8 c, 2 o
Wed: 9 c, 1 o
Thu: 7 c, 3 o
Fri: Off

B

Step-by-step explanation:

The question is:

What percent of time did Nik spend with clients on Thursday?

a. 10%

b. 70%

c. 30 %

d. 80%

Solution:

c means client meetings and o means other work.

The hours are shown in the table.

We want % of time on Thursday that he spent on clients.

In Thursday:

7c and 3o

Means 7 hours with clients and 3 hours with office work.

Total time spent = 7 + 3 =  10 hours

Client time spent = 7 hours

% time spent with clients on Thursday: 7/10 = 0.7 * 100 = 70%

Answer choice B is right.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
