Total voters=v=80
total no. of democrats=d=65
total no. of republicans=r=15
probability of democrats=p1=65/80=0.8125
probability of republicans=p2=15/80=0.1875
probability of a democrat or a republican=p1+p2=0.8125+0.1875=1 <span />
4b. Laura has a 12-foot ladder. The safety instructions recommend the
base of the ladder be placed 4 feet from the base of the wall. How highwill the ladder be able to reach on the wall? WRITE YOUR ANSWER AS A SIMPLIFIED RADICAL.

Answer:
(2,16) , (1, 8)
Step-by-step explanation:
(-1,-7), x = -1 and y = -7
plug in
y = 8x
-7 = 8 * -1
-7 = -8, false
(2,16), x=2 and y = 16
plug in
y= 8x
16 = 8 * 2
16 = 16, so it is a solution
(1,8), x = 1 and y = 8
plug in
y = 8x
8 = 8 * 1
8 =8 , so it is a solution
(-2,-6), x = -2, y = -6
plug in
y = 8x
-6 = -2 * 8
-6 = -16, false
