Answer:B. 86
Explanation: 1032/12=86
To find a percentage of a number, you just need to multiply the percentage by that number.
Percentages must be converted into decimal form before any work can take place. We can do that by either dividing the percentage by 100, or (my personal shortcut) by just shifting the decimal point to the left two places.
276% = 2.76
Then, we just need to multiply.
2.76 * 8 = 22.08
Since the question requires the answer in fraction form, we need to convert 22.08 to a mixed number. This mixed number would be 22 2/25
276% of 8 in fraction form is 22 and 2/25.
Hope this helped =)
Answer:
We conclude that the machine is under filling the bags.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 436.0 gram
Sample mean, = 429.0 grams
Sample size, n = 40
Alpha, α = 0.05
Population standard deviation, σ = 23.0 grams
First, we design the null and the alternate hypothesis
We use one-tailed(left) z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, we conclude that the machine is under filling the bags.
