In anova, by dividing the mean square between groups by the mean square within groups, a(n) Analysis of variance statistic is computed.
What is Analysis of variance ?
- With the help of the statistical analysis approach known as ANOVA, apparent aggregate variability within a data set is explained by separating systematic components from random factors.
- Systematic influences, but not random ones, statistically affect the data set that is being presented.
What are some instances where ANOVA has been applied?
- An ANOVA demonstrates the link between the dependent variable and the level of the independent variable.
- For illustration: In order to determine whether there is a difference in the number of hours of sleep each night as your independent variable, you divide the groups into low, medium, and high social media use categories.

Answer:
C. 16
Step-by-step explanation:
240/15
Step one: 10x15= 150
240-150= 90
Partial quotient: 10
Step two: 6x15= 90
90-90= 0
Partial quotient: 6
Step 3: 10+6= 16
Answer check: 240/15= 16
Answer:
18 small dogs
Step-by-step explanation:
Given the ratio of small dogs to all dogs was 3:7
Total dogs that are there = 42 dogs
Number of small dogs there = ratio of small/ratio of all dogs * Total dogs
Number of small dogs there = 3/7 * 42
Number of small dogs there = 3 * 6
Number of small dogs there = 18
Hence there are 18 small dogs there
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the measures of the 3 sides.
Sum the sides and equate to 75, that is
2x - 9 + 3x + 4 + 2x + 3 = 75, that is
7x - 2 = 75 ( add 2 to both sides )
7x = 77 ( divide both sides by 7 )
x = 11
Thus
AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m
BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m
AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m
