What is the slope of the line through (-9, 6) (-3, 9)
2 answers:
To find the slope, you can use the equation y2-y1 divided by x2 - x1. When you plug in the numbers from the problem, the equation becomes 9-6/-3-(-9). We know that subtracting by a negative is the same as adding a positive, so the equation becomes 9-6/-3+9. When you solve this, it becomes 3/6, which can be simplified to become 1/2. I have attached an image to hopefully make this easier for you to understand because I know it’s a bit confusing written out in words (I’m sorry if the image is bad, I drew it on my phone). If there is anything that you need me to clarify, please let me know and I will be happy to help!

Answer:
0.3875
Step-by-step explanation:
Given that in a group of college students, the ratio of men to women is 3:1 (i.e., 3 to 1). In a recent survey, 40% of the men in this group selected hiking as their favorite outdoor activity whereas 35% of the women in the group selected hiking as their favorite outdoor activity
From the above information we find that
P(Men) = 0.75 and P(women) = 0.25 (since men:women = 3:1)
Out of men prob for not selecting hiking as their favorite outdoor activity
Out of women prob for not selecting hiking as their favorite outdoor activity
Prob for a randomly selected person that hiking is not his/her favorite outdoor activity = Prob (man and not selected activitiy) + P(women and not selected activity) (since men and women are mutually exclusive and exhaustive)
=
