Answer:
The correct option is b) 4.71
Step-by-step explanation:
Consider the provided information.
Test statistic for proportion:
It is given that the claim is that the proportion of accidental deaths of the elderly attributable to residential falls is more than 0.10, and the sample statistics include n=800 deaths of the elderly with 15 percent of them attribute to residential falls.
Therefore, , p = 0.1, q = 1-0.1 = 0.9 and n = 800.
Substitute the respective values in the above formula.
Hence, the correct option is b) 4.71
Answer: The answer is 3n + 2
Step-by-step explanation: You will have to combine like terms:
=−n + −4 + 4n + 6
=(−n + 4n) + (−4 + 6)
=3n + 2
We can only add and subtract fractions that have the same bottom numbers. If fractions have the same bottom numbers, we can add them by just adding the top numbers and and keeping the original bottom number.
If they don't have the same bottom number, we have to find the least common denominator for those fractions which is simply the least common multiple of the two or how ever many fractions there are.
For example, to add 1/2 and 1/3, we find the least common
denominator, which is 6, and we want to get a 6 in the denominator.
When we have the same denominator, just add
the numerators and keep the original denominator.
