Answer:
B) 264 units²
Step-by-step explanation:
Figure 1:
A = 1/2BH
A = 1/2 12(4)
A = 1/2 48
A = 24
Figure 2:
24 - 4 = 20
20 x 12 = 240
Total area:
240 + 24 = 264
Answer:
40 degrees
Step-by-step explanation:
- All internal angles of a triangle add up to 180 degrees.
- A right angle is 90 degrees.
90+50=140
subtract 140 from 180, which is 40 degrees.

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
