Answer:

X = 1/2 and X = 5/4

Step-by-step explanation:

7x^2 - 14x + 5 = -x^2

8x^2 - 14x + 5 = 0

(2x - 1) + (4x - 5) = 0

To find X1

2x - 1 = 0

2x = 1

x = 1/2

To find X2

4x - 5 = 0

4x = 5

x = 5/4

The incomplete table above summarizes the number of left-handed students and right-handed students by gender for the eighth grad

creativ13 [48]

Answer:

The answer is A

Step-by-step explanation:

x+y=18

5x+9y=122

When you solve this system of equations, you get x=10 and y=8. Thus, 5*10, or 50, of the 122 right-handed students are female. Therefore, the probability that a right-handed student selected at random is female is

50/122

which to the nearest thousandth is 0.410.
