Answer:
D
Step-by-step explanation:
Think about the question, you can't say that i am wong.
Well you need first 1 2/4 of a yard. Then you will need 5/6 of a yard. But first you need to put them together. So we need to find the common denominator. Six and four both share which multiple? Twelve. So let's rewrite that. You need 1 6/12 yards + 10/12 yards of wrapping paper. But before we do anything else we need to fix the mixed number. 1 6/12 isn't as easy to add ad 18/12 is. So 18/12 + 10/12 = 28/12
That can simplify as well. Now it's 14/6 which is equivalent to the fraction we had before. But it can also go down to 2 2/6. Now we can simplify it even further. By dividing it by two we can get 2 1/3. These are the measurements we need. So you would need how many thirds? Seven. (2 1/3 is seven thirds) This is your final answer.
You would need to have seven peices of wrapping paper cut to wrap both gift boxes.
If earning more money from a college degree occurs, a researcher is interested in finding out. She is aware that the average annual household income in thousands is μ<=80.
The null hypothesis is a claim made about the population parameter in relation to the test's goal and in opposition to the alternative hypothesis.
- The term "null hypothesis" refers to a researcher's attempt to reject or "nullify" a commonly held assumption (such as that the sky is blue). A null hypothesis is "a statistical theory suggesting that no statistical relationship exists between given observed variables," according to a more formal definition.
- It always contains = , ≤ , ≥ signs.
- The results will be examined using a one-tailed hypothesis test.
Hence, μ<=80
