To simplify we can collect like terms so we get -1.7f-18 :)
Answer:
{-3, 8}
Step-by-step explanation:
This rational expression is undefined wherever the denominator is 0.
Thus, our task is to determine the roots of x² - 5x - 24:
This expression factors as follows: (x - 8)(x + 3) = 0
Setting x - 8 = 0 and solving for x yields x = 8.
Similarly, x + 3 = 0 yields x = -3.
This rational expression is undefined for {-3, 8}.
Using the binomial distribution, it is found that there is a 0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.
For each chicken, there are only two possible outcomes, either they are contaminated, or they are not. The chickens are independently selected, hence, the binomial distribution is used.
<h3>What is the binomial probability distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- About 30% of frozen chickens are contaminated, hence .
- Chickens are delivered to grocery stores in crates of 24, hence .
The probability that a certain crate has <u>more than 4 contaminated</u> chickens is:
In which:
Then
Hence
0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.

Answer:
Denote the principal amount: P
In 25 years, a bond with a 4.75% annual interest rate earned $2,375 as interest.
=> P x (1 + 4.75/100)^25 - P = 2375
=> P x 3.19 - P = 2375
=> P x 2.19 = 2375
=> P = 2375/2.19 = 1084.48$
Hope this helps!
