Answer:
-x^4-10x+1/10
Step-by-step explanation:
standard form goes from biggest power to smallest power
Let n = required random sample size.
Assume that the population standard deviation is known as σ.
Let m = sample mean.
At the 95% confidence level, the expected range is
(m - k(σ/√n), m + k(σ/√n))
where k = 1.96.
Therefore the error margin is 1.96(σ/√n).
Because the error margin is specified as 3% or 0.03, therefore
(1.96σ)/√n = 0.03
√n = (1.96σ)/0.03
n = 128.05σ²
This means that the sample size is about 128 times the population variance.
Answer:
Smallest sample size = 128.05σ², where σ = population standard deviation.
Answer:
when you divide you get -11/12
if you have a calculator you could add the 5/8 and 3/4
then add the -2/3 and the -5/6
then divide the first answer by the second answer
The answer is 1:11. After it being simplified from 6:66. Hope this helps.
To rewrite, all we have to do is apply the associative property of addition. It allows us to write the expression as <br /><br />y + (1 + 4) <br /><br />we could even take it one step further and combining our terms for<br /><br />y + 5
