1) 5.10-2.8.16. 10-1
const2013 [10]

Answer: -2511 (if the periods mean multiplication)

Step-by-step explanation:

I’m not sure whether you’re trying to have the periods be multiplication, but if that’s what they are, this is the answer

5x10-2x8x16x10-1

50-16x160-1

50-2560-1

-2511

Again, I’m not sure if that’s what you mean but I can’t really see what else they would mean since you can’t have a 3 part decimal

A) choose the linear model that passes through the most data points on the scatterplot.
irina1246 [14]
Answer: b

Explanation:
The line of best fit to a scattergram is obtained in linear regression analysis by minimizing the sum of the squared errors.
For example, in the diagram shown below, there are n data points in the scattergram.
The error for the i-th data point is e_{i}.
The coefficients (a and b) for the line of best fit are determined using calculus, to minimize \sum_{i=1}^{n} e_{i}^{2}.
