If you carry out a two-factor ANOVA (main effects model) on a dataset with Factor A at four levels and Factor B at five levels, with one observation per cell, how many degrees of freedom will there be for:

a. Factor A?
b. Factor B?
c. Interaction?
d. Error?

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

imma say 16%. sorry if its wrong. i'm doing the same stuff right now

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
