4/5 because in y=mx+b format, the “m” represents slope, or the number in front of the x

Factor the polynomial by its greatest common monomial factor.

inna [77]

Answer:

$5 {y}^{2} (4 {y}^{4} - 3 {y}^{2} + 8)$

Step-by-step explanation:

We want to factor the common monomial out of :

$20 {y}^{6} - 15 {y}^{4} + 40 {y}^{2}$

The greatest common monomial fact is

$5 {y}^{2}$

We factor to get:

$5 {y}^{2} (4 {y}^{4} - 3 {y}^{2} + 8)$

The expression in the parenthesis has no common factor again since we factored the greatest common factor.

What are the relative frequencies, to the nearest hundredth, of the rows of the two-way table? Drag and drop the values into the

quester [9]

Answer:

.25 .75

.44 .56

Step-by-step explanation:

To find the relative frequency, we take the part over the total.

Since this is a relative frequency table, the total for each row is 1

Group 1 A = 15/ (15+45) = 15/60 = .25

Group 1 B = 45/(15+45) = 45/60 = .75

Group 2 A = 20 /(20+25) = 20/45 =.44

Group 2B = 25/(20+25) = 25/45 =.56
