Answer: Option C, 
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.
Answer: A
Step-by-step explanation:
Answer:
n = 2.6
Step-by-step explanation:
6.5 : 5
n : 2
6.5/5 = 1.3
2 x 1.3 = 2.6
n = 2.6
i hope this helps
For number 16, keep the slope and plug in the values of x and y and solve for the y intercept. For 20 take the opposite reciprocal and then plug in the values of x and y and solve for y intercept. For number 24 and 25 convert both into slope intercept form (y=mx+b) and see if they are parallel or perpendicular
