Answer:
-5/4, 5
Step-by-step explanation:
h(x)=(-4x -5)(-x +5) = 0
-4x-5 = 0
x = -5/4
-x+5 = 0
x = 5
Using the binomial distribution, it is found that there is a 0% probability that fewer that 5 in a sample of 20 pills will be acceptable.
For each pill, there are only two possible outcomes, either it is acceptable, or it is not. The probability of a pill being acceptable is independent of any other pill, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
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:
- The sample has 20 pills, hence .
- 100 - 4 = 96% are acceptable, hence
The probability that <u>fewer that 5 in a sample of 20 pills</u> will be acceptable is:
In which
0% probability that fewer that 5 in a sample of 20 pills will be acceptable.

Alright, so I=prt. I is 1090-900=190=interest. It starts at 900, so that is p. R is 0.09. 1090=900*0.09*t, so 1090/(900*0.09)=t=around 13 years
To solve this question, you want to try to get the variable alone on one side.
So, your starting equation is 7a-3=3+6a. You want to subtract 6a from both sides of the equation, so that the variable a is only on the left side of the equation.
So, after subtracting, your equation looks like a-3=3. Next, you want to add 3 to both sides, to cancel out the -3 on the left side of the equation.
If performed correctly, your equation should be a=6.
Your final answer is a=6.
