So lets add the common fractions 3/4+3/4+1/4+1/2=7/4+1/2=18/8, now the whole numbers 3+1+2+4+2=12, so 12 18/8 and simplify 14 2/8= 14 1/4 <span />

Step-by-step explanation:
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
