Answer:
0.917915
Step-by-step explanation:
Exponential distribution is expressed as it follows
F (y,λ) = 1 – e ^(- λ(y)
)
Where λ is equal to 1/ population mean
So λ = 1/2.8 = 0.357
Let y be the length of time a costumer wait on hold
Now, let´s find the value for y = 7 minutes, which is the proportion of costumer that wait on hold
P (y<7) = 1 – e^(- .357*(7)
)
P (y<7) = 0.917915
12 cm, use the pythagorean theorem: a^2+b^2=c^2
5^2+b^2=13^2
25+b^2=169
b^2=144
b=12
12 cm

The range of is the set of all real values
<h3>How to determine the range?</h3>
The function is given as:
The above function is a parent logarithmic function.
The parent logarithmic function have a range of the set of all real values
Hence, the range of is the set of all real values
