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
Answer:
Option B.
Step-by-step explanation:
Area of the composite figure = Area of the rectangle- area of the semicircle removed
= (length × width) -
Since diameter of the semicircle is the width of the rectangle.
So, radius of the semicircle =
= (3.8 × 9.2) -
= 34.96 - 5.6677
= 29.2923
≈ 29.3 in²
Therefore, area of the given composite figure is 29.3 in².
Option B is the correct option.
There’s 100 students in the drama club and 84 students in the yearbook club
Answer:
4(x+3) = 20
Distrbute
4x+12 = 20
-12 from both sides
4x = 8
divide both sides by 4
x = 2
