Answer:
(a) P (none) = 0.005873
(b) P ( at least one household ) = 0.9941
(c) P ( at most one household ) = 0.9960
(d) not wrong
Step-by-step explanation:
Given data
probability P = 29% = 0.29
no of sample n = 15
tv show X = 50
to find out
the probability that none of the households
the probability that at least one household
the probability that at most one household
If at most one household is tuned to 50 Minutes, does it appear that the 19% share value is wrong
solution
the probability that none of the households is tuned to 50 Minutes is
P (none) = 10C0 × ×
P (none) =
P (none) = 0.005873
and the probability that at least one household is tuned to 50 Minutes is
P ( at least one household ) = 1 - P(none)
P ( at least one household ) = 1 - 0.005873
P ( at least one household ) = 1 - 0.005873
P ( at least one household ) = 0.9941
the probability that at most one household is tuned to 50 Minutes is
P ( at most one household ) = P (none) + P (x=1)
P ( at most one household ) =0.9941 + 10C1 × ×
P ( at most one household ) = 0.9960
and in last part If at most one household is tuned to 50 Minutes it appear that the 19% share value is not wrong
because P( at most one household ) is not zero

2) Rectangular shape is square shape patio !
<u>Step-by-step explanation:</u>
Here we have , the area of Bianca’s rectangular backyard patio is represented by the expression x2 – 18x + 81, and the length of the patio is represented by the expression x − 9: We need to find
1. what is the expression for the width of the patio? Explain and show all work.
We know that area of rectangle =
⇒
Factorizing RHS:
⇒
⇒
⇒
⇒
2. what special rectangular shape is the patio?
Now , we see that
A rectangle whose length & width are equal is known as a square ! Hence , Rectangular shape is square shape patio !
