Solving for the value that makes both true
dvide the left equation by 3 to simplify
3x-2y=1
oh, they are same equaiton
inifnite solutions
the solutions are the points on the line y=(3/2)x-(1/2)
The correct mean is 18.3 because you add 1.8 to the mean.
-3+-8. -11
——— = —–
2. 2
-1+6. 5
—— =. —
2. 2
answer is (-11/2 , 5/2)
Answer:
The company's chocolate bars weigh 1.6 ounces on average.
Step-by-step explanation:
We are given that a company claims that its chocolate bars weigh 1.6 ounces on average.
It took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.
95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.
Thus by definition we can say that The company's chocolate bars weigh 1.6 ounces on average.
Hence Option B is correct.
