3(3)^2 - (-2)^3 - (-2)^3 + 5
27 - (-8) - (-8) +5
35 - (-8) + 5
43 + 5
48
Order the list from least to greatest:
-12, -9, 0, 8, 15, 16, 17
subtract the least from the greatest: 17 - (-12)
17 + 12 = 29
The range is 29
hope this helps
Answer:
20.24 cm
Step-by-step explanation:
Here, since the age of the crab is given in months and the regression line was computed using the age in months, we just have to replace the value of the age in the formula to estimate the size.
The formula obtained for the estimated size Y was
Y = 9.1411 + 0.4775X
where X is the age in months
Replacing X with 23.2417, we get
Y = 9.1411 + 0.4775*23.2417 = 20.24 cm
The ratio 4 to 7. would be 12 and 21
