Answer:
AH! Quadratic Equations?!?!?!??
Step-by-step explanation:
The discriminant is the this part of the quadratic formula(the one in parentheses)

So let's take it out!

(if you don't know what a quadratic equation is, why are you doing this to yourself?)
REMINDER: Quadratic equation: x^2+bx+c=0
So let's input the values into this and find out!
It is more likely that the last three will have a negative discriminate so:
3:
49-12
37
Nope! Positive!
4:
16+8
Nope!Positive!
5:
9-16
Found It!
Hope this helps.
FYI it's option 5
Answer:
a. 68
b. 128 moderates
c. The percentage of females in the sample
Step-by-step explanation:
Total high school student = 347.
There are 95 liberals of which 27 are males and 68 are females.
Of 128 Moderates, 91 are females and males are 37 in number
To find the total number of conservatives, we have:
Total no - (total moderates + total liberals) = total conservatives
347 - (128 + 95)
347 - 223
= 124 number of conservatives of which females are 93 and males are 31.
a. The joint frequency for liberal females is 68
b. And the largest marginal frequency for political preference is 128 moderates
c. what does the relative frequency 252/347 represent?
answer: total females: 68 + 91 + 93 = 252 out of 347 students. The percentage of females in the sample

You use the equation Final Velocity²= (Initial Velocity)² 2(Acceleration)(Distance). You plug in what you have 0²=22.4² X 2(-3.5)(D) and solve for D which is 71.68m or about 72m.
