It would be ‘F’, because 0.30 times 8 is 2.40, and 0.30 times 5 is 1.50, so the constant rate would be 0.30 cents per corn
Answer: -3n-2.
Because for the first term, for example, plug in 1, you'll get -3(1)-2=-3-2=-5, which is the first one. Try it with all terms.
300.50 + 0.07x > = 900.85
0.07x > = 900.85 - 300.50
0.07x > = 600.35
x > = 600.35 / 0.07
x > = 8576.43 <=== she would have to sell at least 8576.43
Since the sample is greater than 10, we can approximate this binomial problem with a normal distribution.
First, calculate the z-score:
z = (x - μ) / σ = (37000 - 36000) / 7000 = 0.143
The probability P(x > 37000$) = 1 - P(<span>x < 37000$),
therefore we need to look up at a normal distribution table in order to find
P(z < 0.143) = 0.55567
And
</span>P(x > 37000$) = 1 - <span>0.55567 = 0.44433
Hence, there is a 44.4% probability that </span><span>the sample mean is greater than $37,000.</span>
