Answer:
y is equal to 65 so 115 isn't a possible answer
It’s meters squared. Since you need to find the area in order to find the amount of fertilizer, the area is expressed as the unit squared.
2,213,000, 6 is closer to 10 than 0.
For margin of error to be a maximum of 3:
3 = z*(SD / sqrt(n)), where z is the z-score, SD is the standard deviation and n is the sample size.
z = 1.96 for a 95% confidence interval, and we are given SD = 15.
3 = 1.96*15/sqrt(n)
sqrt(n) = 9.8
n = 96.04 ~ 96 commercials.
Answer:
The correct answer is:
Step-by-step explanation:
By evaluating first, and then the mathematical calculation, we have:
