Answer:
Step-by-step explanation:
-0.25x+1.75x<-1.75+2.5 x
sift terms containing x to right and constant term to left
1.75<2.5 x+0.25x-1.75 x
1.75<2.75x-1.75x
1.75<1.00 x
or 1.75 <x
or x>1.75

Answer:
y=-1/2x+2
Step-by-step explanation:
Solve for y:
4y= -2x+8 (move 2x to the other side to isolate 4y)
y=-2/4x+8/4 (divide by 4 on both sides to isolate y)
y=-1/2x+2 (simplify, gives equation y=mx+b)
slope=-1/2 and y-intercept=2 (m=slope & b= y-intercept)
4P2 * 2P1 * 3P2
you want to use permuations instead of combinations because order matters.
12*2*6=144
Answer:
So, the probability is P=0.094.
Step-by-step explanation:
We know that in a recent survey, 73% of the community favored building a police substation in their neighborhood.
We get that p=0.73 and q=1-0.73=0.27.
We calculate the probability that exactly 8 of them favor the building of the police substation, if 14 citizens are chosen.
We get that n=14 and k=8.
We calculate the probability:
So, the probability is P=0.094.
