Answer:
0.1749
Step-by-step explanation:
We are to find the probability that none of the house-holds tuned to 50 minutes.
P(tune to 50 minutes) = 0.16
p = 0.16
q = 1 - 0.16
q = 0.84
number of households (n) = 10
x = number of households that tuned at 50 minutes
since none of the household tuned, then:
x = 0
Using the binomial expression:




P(x =0) = 0.1749
Answer:
A = 240 units²
Step-by-step explanation:
the area (A) of a regular polygon is
A =
pa ( p is the perimeter and a the apothem )
here p = 8 × 6 = 48 ( an octagon has 8 sides ) and a = 10 , then
A =
× 48 × 10 = 24 × 10 = 240 units²
That would 32a - 8, Good Luck!

Answer:
Inverse of

Step-by-step explanation:
Let y = -5x-4
Swap y and x
x = -5y -4
Solve for y
x+4 = -5y
which is the inverse
