Answer:
may have different df values but they all have the same denominator
Step-by-step explanation:
In a two-factor analysis of variance, the F-ratios for factor A, factor B, and the AxB interaction _____. may have different df values but they all have the same denominator
In two--factor analysis of variance, the estimates of the variance can be obtained by partitioning the total sum of squares into three components corresponding to the three possible sources of variation , viz; Between Rows, Between Columns, and Within Samples or error.
As the number of rows and columns may differ the degrees of freedom differ with them.
In other words
Total df= Rows df + Columns df + Error df
Since the variance is identically the same for each row of the c values and variance is the same for each observation in the jth column of r values the sum of squares becomes an identity.
Therefore it may have different df values but they all have the same denominator.
3. This was spun 50 times, and it landed on yellow 6 times. Therefore, it won't land on yellow all but 6 times. P(not yellow) is 44/50, or 22/25.
4. If 50 students are asked, and 7 have a dog, then the probability is 7/50. We can use a proportion to find the equivalent of 7/50 with a denominator of 1400, because that is how many people are at the school. 7/50=x/1400. 50x=9800. x=196
Answer:
GCF = 4xy⁷z
Step-by-step explanation:
Do Prime Factorizations for each term and select only those terms common to each:
28xy⁹z = 2·2·7·x·y·y·y·y·y·y·y·y·y·z
32x²y⁷z = 2·2·2·2·2·x·x·y·y·y·y·y·y·y·z
GCF = 2·2·x·y·y·y·y·y·y·y·z
GCF = 4xy⁷z
Answer:
115
Step-by-step explanation:
The angle of a straight line is 180°. so all you have to do is subtract 65 from 180 and get 115.
