Answer:
You have your x and y mixed up
Step-by-step explanation:
Look at your table. You labeled y1 and y2 where the x's are. y2 = 8, y1 = 4, x2 = 12 and x1 = 6. The slope then is (8-4)/(12-6) which is 4/6 or 2/3. You did run over rise instead of rise over run. Be careful. I see that a lot when I teach the concept to beginners.
For this case we have:
Let be a given function, where:
- x is an independent variable
- y it is a dependent variable
By definition, the domain of a function is represented by the values associated with the independent variable, that is, the values of x.
Therefore, the domain of the given function is represented by:
Answer:
The smallest number is 67/1000, then 0.672, then 68%, then 0.7, and the largest is 0.7
Using the binomial distribution, the probabilities are given as follows:
- 0.3675 = 36.75% probability that more than 4 weigh more than 20 pounds.
- 0.1673 = 16.73% probability that fewer than 3 weigh more than 20 pounds.
- Since P(X > 7) < 0.05, it would be unusual if more than 7 of them weigh more than 20 pounds.
<h3>What is the binomial 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.
The values of the parameters for this problem are:
n = 10, p = 0.4.
The probability that more than 4 weigh more than 20 pounds is:
In which:
Then:
Hence:
0.3675 = 36.75% probability that more than 4 weigh more than 20 pounds.
The probability that fewer than 3 weigh more than 20 pounds is:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0061 + 0.0403 + 0.1209 = 0.1673
0.1673 = 16.73% probability that fewer than 3 weigh more than 20 pounds.
For more than 7, the probability is:
Since P(X > 7) < 0.05, it would be unusual if more than 7 of them weigh more than 20 pounds.

7B + 4 = 7B - 3
We need to solve for B
Let's add 3 in both sides:
7B + 4 = 7B - 3
7B + 4 + 3 = 7B - 3 + 3
7B + 7 = 7B
Let's subtract 7B from both sides:
7B + 7 = 7B
7B - 7B + 7 = 7B - 7B
7 = 0
7 = 0, which is impossible. 7 can never be 0, and 0 can never be 7.
So the equation have no solution.
