Answer:
159 metros cúbicos
Step-by-step explanation:
Os metros cúbicos de água que Isabel e sua família consumiram durante este período são calculados como:
Nova leitura - primeira leitura
Primeira leitura = 2.431 metros cúbicos
Nova leitura = 2590 metros cúbicos
Conseqüentemente:
2.590 metros cúbicos - 2.431 metros cúbicos
= 159 metros cúbicos

Step-by-step explanation:
Answer:
1. The sum of the residuals is always close to zero.
2.The coefficient of determination measures how much of the variation in the y-values is explained by the regression line.
3. In the equation of the least-squares regression line, y hat is a predicted value when x is known
Step-by-step explanation:
The least square regression line is a line that makes distance from data points to the regression line to be as minimal as possible. This line is a best fit for the data points. Let's say we have a collection of numbers and a scatter plot, this line is a line that exists and best fits the data.
Therefore, the least square regression line minimizes sum of squared error to be close to zero. R² measures the extent to which variations in the value of y is explained by the regression line. In the equation of this line, y hat is a predicted value when x is known.
Hot dogs are sold in packs of 10. 30 divided by 10 equals 3. (30/10=3)
Buns are sold in packs of 8. 30 divided by 8 equals 3.75. (30/8=3.75) but we must round to 4 since we can’t buy 75% of a pack of buns.
3 packs of hotdogs and 4 packs of buns
