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
Step-by-step explanation:
m∠3 = 7x - 10
m∠6 = 5x + 10
m∠3 = m∠6
7x - 10 = 5x + 10
7x - 5x = 10 + 10
2x = 20
x = 20/2 = 10°
Answer:
Step-by-step explanation:
question 1a) hey, so it would look like this for example:
question 1b) no, because they don't follow the rules of a 30-60-90 triangle (like the one shown below)
tell me if u have any questions
Step-by-step explanation:
33/4=8.25
-21/2= -10.5
8.25÷-10.5=0.785
I dont understand what you are asking
