Answer:
x=0 or x=1
Step-by-step explanation:
(x−2)(−5x2+x)=x(−5x2)+x−2(−5x2)−2x
−5x3+11x2−2x=−5x3+10x2−x
Step 1: Add 5x^3 to both sides.
−5x3+11x2−2x+5x3=−5x3+10x2−x+5x3
11x2−2x=10x2−x
Step 2: Subtract 10x^2-x from both sides.
11x2−2x−(10x2−x)=10x2−x−(10x2−x)
x2−x=0
Step 3: Factor left side of equation.
x(x−1)=0
Step 4: Set factors equal to 0.
x=0 or x−1=0
x=0 or x=1
Answer:
4m
Step-by-step explanation:
We are looking for the circumference
We need to find the radius
r = d/2 = 1.2/2 = .6
C = 2*pi*r
C = 2*pi*(.6)
C = 1.2*pi
We can approximate pi by 3.14
C =1.2*3.14
C =3.768 m
To the nearest meter
C = 4m
Answer:
12:20:25
I thnk this is it. I'm not sure though
The answer would be 23i.
Simplify ( 26 + 16i - 26 + 7i )
Gather like terms ( 26 - 26 ) + (16i + 7i)
Simplify (23i)
Answer:
0.0159
Step-by-step explanation:
Given that a common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight.
Here if X is the no of persons that do not show up, then X is binomial as each trial is independent with p = 0.04 and n =150 (no of tickets sold)
The plane is overbooked if more than 150 show up
i.e. less than 2 do not show up
Hence the probability that the airline overbooked this flight
=
