Answer:
The probability is 
Step-by-step explanation:
Consider a political discussion group consisting of 10 Democrats, 10 Republicans, and 5 Independents.
Total members of the group = 
Selecting 2 republicans in succession means selecting 1st republican out of 10 republicans and total 25 members and then selecting 2nd republican out of 9 left republicans and 24 members.
Hence, probability becomes:

= 
So, the probability is 
Slope: (y2-y1)/(x2-x1)
(3-3)/(2-10) = 0/-8 = 0
The slope is 0
Answer:
T = ±22
Step-by-step explanation:
Let's solve your equation step-by-step.
0=−16t2+7744
Step 1: Add 16t^2 to both sides.
0+16t2=−16t2+7744+16t2
16t2=7744
Step 2: Divide both sides by 16.
16t2
16
=
7744
16
t2=484
Step 3: Take square root.
t=±√484
t=22 or t=−22
Subtract what is to the right of the equal sign form both side of the equation but any way the answer is 0
