Answer:
0.4224 = 42.24% probability he will find an expired meter BEFORE the 3rd one
Step-by-step explanation:
For each car, there is a 24% probability that it had expired parking meters.
What is the probability he will find an expired meter BEFORE the 3rd one?
Three possible outcomes:
Two expired(each with 24% probability)
First expired(24% probability) and second not(76% probability)
First not(76% probability) and second expired(24% probability). So
0.4224 = 42.24% probability he will find an expired meter BEFORE the 3rd one
Answer:
y = 5/4 x
Step-by-step explanation:
We already know the slope, so now we need to find the y-intercept. To do that, you need to simply plug the coordinates into the equation which is
y = 5/4 x + b
-5 = 5/4 (-4) + b
-5 = -5 + b
0 = b
y = 5/4 x + 0 or simply just y = 5/4 x.
Answer:
y=-4x-5
Step-by-step explanation:
thats how you write it in y=mx+b form
h ope this helps. :)
13x-2. 2•5x=10x 2•-1=-2. 10x-2+3x=13x-2
<h2>T
he small mass should be placed at x = 11.72 cm or x = 68.28 cm </h2>
Step-by-step explanation:
Let the small mass be m and position on x axis be y.
A 20 kg sphere is at the origin.
Distance to 20 kg mass = y
A 10 kg sphere is at x = 20 cm
Distance to 10 kg sphere = 20 - y
We have forces between them are equal
We have gravitational force
Where G = 6.67 x 10⁻¹¹ N m²/kg²
M = Mass of body 1
M = Mass of body 2
r = Distance between them
Here we have
So the small mass should be placed at x = 11.72 cm or x = 68.28 cm
