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

Use the zero product property to find the solutions to the equation x^2 + x -30=12
Alla [95]

Answer:

The solutions are x = -7, 6.

Step-by-step explanation:

To find the solutions, move everything to one side of the equation so the equation is equal to 0. Then factor. Set the factors equal to 0 and solve for x.

x^2 + x - 30 = 12\\x^2 + x -42=0\\(x+7)(x-6) = 0

x+7 = 0

x = -7

and

x-6 = 0

x = 6

The solutions are x = -7, 6.
