Question

The total amounts of rainfall at various points in time during a thunderstorm are shown in the table. Rainfall During a Thunderstorm Time (hours) 0.4 1.1 2.9 3.2 3.7 4.4 Rainfall (cm) 0.3 0.6 1.8 2.0 2.2 2.6 According to a regression calculator, what is the equation of the line of best fit for the data? A calculator screen. A 2-column table with 6 rows titled Data. Column 1 is labeled x with entries 0.4, 1.1, 2.9, 3.2, 3.7, 4.4. Column 2 is labeled y with entries 0.3, 0.6, 1.8, 2, 2.2, 2.6. The linear regression equation is y almost-equals 0.594 x + 0.029; r almost-equals 0.998. y almost-equals 0.06 x + 0.03 y almost-equals 0.06 x + 0.29 y almost-equals 0.59 x + 0.03 y almost-equals 0.59 x + 0.29

Answer 1

Answer:

y approximately is equal to 0.59x + 0.03, the third option.

Step-by-step explanation:

Answer 2

Answer:

C. y almost-equals 0.59 x + 0.03

Step-by-step explanation:

The linear regression equation is y ≈ 0.594 x + 0.029; r ≈ 0.998.

0.594 must be rounded down to 0.59 (digits finished in 1, 2, 3 and 4 are rounded down)

0.029 must be rounded up to 0.03 (digits finished in 5, 6, 7, 8 and 9 are rounded up)
