Answer:
21, 15
Step-by-step explanation:
12+9=21
the third side of a triangle must be equal to the two other sides added up to make it possible
also 15 if you're trying to make a possible right triangle
Answer: can I have more context?
Step-by-step explanation:
Let y be the yield of bushels of wheat in comparison to the amount of rainfall
Let x be the amount of rainfall that occurs (in inches)
If the linear regression equation is y = 47.3 + 0.78x, then per inch of rainfall will yield an addition 0.78 bushels (plugging into x the additional inches of rainfall).
Therefore, on the first inch of rainfall, y = 48.08.
On the second inch of rainfall, y = 48.86.
And so on.

Answer:
B. Sample mean used to estimate a population mean.
C. Sample variance used to estimate a population variance.
D. Sample proportion used to estimate a population proportion.
Step-by-step explanation:
This is because the mean of the sampling distribution of the mean tends to target the population mean. Also, the mean of the sampling distribution of the variance tends to target the population variance.
This means that the sample mean and variance tend to target the population mean and variance, respectively, instead of systematically tending to underestimate or overestimate that value. This is why sample means and variances are good estimators of population means and variances, respectively. This is also true for proportions but not true for medians, ranges and standard deviations.
