Answer:
since we have four groups, the number of population k = 4
Option C. 4 is the correct answer
Step-by-step explanation:
Given the data in the question;
Number of group k = 4
the number of cases in each group = 30
so
n = 4 × 30
n = 120
SS_total = df = n - 1
= 120 - 1
= 199
SS_between = k - 1
= 4 - 1
= 3
since we have four groups, the number of population k = 4
Option C. 4 is the correct answer
Answer:
The answer to your question is x = 18
Step-by-step explanation:
Use this problem using proportions
![\frac{QR}{LM} = \frac{RT}{MO}](https://tex.z-dn.net/?f=%5Cfrac%7BQR%7D%7BLM%7D%20%3D%20%5Cfrac%7BRT%7D%7BMO%7D)
Substitution
![\frac{x}{30} = \frac{9}{15}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B30%7D%20%3D%20%5Cfrac%7B9%7D%7B15%7D)
Solve for "x"
x = ![(30) \frac{9}{15}](https://tex.z-dn.net/?f=%2830%29%20%5Cfrac%7B9%7D%7B15%7D)
Simplification
x = ![\frac{270}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B270%7D%7B15%7D)
x = 18
Answer:
predicted: 15.7
residual: 1.3
Step-by-step explanation:
In x-axis, age of the tree is represented, and in y-axis, height of the tree is represented. When the tree is 5 years, x = 5, and the predicted value is:
f(5) = 1.3(5) + 9.2 = 15.7
Residual value is computed as follows:
residual = observed - predicted
residual = 17 - 15.7 = 1.3
4 only has three factors 1,2,4. 4 times 1 and 2 times . No other possible combinations making Adam wrong.
20 + 20 + 30 + 15 + 40 = 125
125/5= 25
25-15 = 10
Absolute deviation for 15 is 10
