The value of x is 5.5. I got this answer by first distributing -3 amongst (x-11), and distributing 7 amongst (2x-5). Next I combined like terms and subtracted 3x from 5x, and added -35 and 2. Next I subtracted 33 from both sides. Next I subtracted 14x from both sides. And finally I divided both sides by -12 to get the final answer of 5.5.
Answer:
x= -7 x = -4
Step-by-step explanation:
x^2 + 11x + 28 = 0
What two numbers multiply to 28 and add to 11
7*4 = 28
7+4 =11
(x+7) (x+4) =0
Using the zero product property
x+7 =0 x+4 =0
x= -7 x = -4
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)
=
The speed is 630mp/s I think. Because you have to multiply Wavelength by Frequency to get true speed
