3-8+4-6+1=
-5+4-6+1=
-1-6+1=
-7+1=
-6=
The Answer is -6
Answer:
the first answer option
Step-by-step explanation:
|x + 4| = 2
so,
(x + 4) must be +2 or -2 to make the original equation true.
when is (x + 4) = 2 ?
x + 4 = 2
x = -2
when is (x + 4) = -2 ?
x + 4 = -2
x = -6
so, -6 and -2 are the correct solutions.
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
