Answer:
a) The probability that at least 5 ties are too tight is P=0.0432.
b) The probability that at most 12 ties are too tight is P=1.
Step-by-step explanation:
In this problem, we could represent the proabilities of this events with the Binomial distirbution, with parameter p=0.1 and sample size n=20.
a) We can express the probability that at least 5 ties are too tight as:
The probability that at least 5 ties are too tight is P=0.0432.
a) We can express the probability that at most 12 ties are too tight as:
The probability that at most 12 ties are too tight is P=1.
The length of the rectangle is 14 feet and the width of the rectangle is 9 feet.
The length of a rectangle is 5 more than the width. The area is 126 square feet.
We need to find the length and width of the rectangle.
<h3>What is the area of a rectangle?</h3>The area of a rectangle is calculated by multiplying the rectangle's length by its width.
Let the width of the rectangle be x, then the length of the rectangle be x+5.
We know that the area of the rectangle = Length×Width
Now, the area of the rectangle = (x+5)×x=126 square feet.

Since length cannot be a negative integer.
So, Width=9 feet and Length=9+5=14 feet.
Hence, the length of the rectangle is 14 feet and the width of the rectangle is 9 feet.
