Answer:
Area = pi X r^2 = pi x (1)^2 = 3.14 x 1 = 3.14
Step-by-step explanation:
Answer:
f(x) = - 3x + 4
Step-by-step explanation:
Note that y = f(x)
Given
9x + 3y = 12 ← Rearrange making y the subject
Subtract 9x from both sides
3y = - 9x + 12 ( divide all term by 3 )
y = - 3x + 4, thus
f(x) = - 3x + 4
Answer:
The answer is B) 0.57.
Step-by-step explanation:
In this problem we have to apply queueing theory.
It is a single server queueing problem.
The arrival rate is 
and the service rate is 
.
The proportion of time that the server is busy is now as the "server utilization"and can be calculated as:
where c is the number of server (in this case, one server).
(this shows the percent of people that would work over time on a regular basis out of the 30 people) 12/30= (40%) of the 30 said they would work overtime.
200×.4=80 employees of the 200 would have probably have said they would work overtime.
Answer:
Step-by-step explanation:
<u>Exponential function is:</u>
<u>Use two points on the graph to determine the value of a and b:</u>
<u>Find the values of a and b:</u>
- f(0) = a*b⁰ = a = 100
- f(1) = a*b¹ = ab = 100b = 50 ⇒ b = 50/100 = 1/2
<u>The function is:</u>
