There are three motors available to repair Ralph’s vacuum cleaner. Motor #1 has a 65% chance of breaking by the end of the week.
Orlov [11]

Answer:

0.619

Step-by-step explanation:

from the question we have the following data:

probability of motor 1 breaking = 65% = 0.65

probability of motor 2 breaking = 35% = 0.35

probability of motor 3 breaking = 5% = 0.05

since we have 3 motors the probability of any of them breaking down is  = \frac{1}{3}

but what the question requires from us is the conditional probability of the first one being installed

we have to solve this questions using bayes theorem

such that:

\frac{0.65*\frac{1}{3} }{0.65*\frac{1}{3}+0.35*\frac{1}{3}+0.05*\frac{1}{3}   }

= \frac{0.2167}{0.2167+0.1167+0.0167}

= \frac{0.2167}{0.3501}

= 0.618966

approximately 0.619

therefore the conditional probability ralph installed the first motor is 0.619

A certain bacterial culture is multiplying in a culture dish, doubling in size every 6 minutes. It takes exactly an hour to fill
Anastaziya [24]
1 hours to fill the dish
for 1/2 of the dish
think
1/2 times 2=2/2=1 so therefor it takes 1 less doubling so

60 mins
1 less double
(double is 6 mins so )
60-6=54

What is 2x+y=4 and 2x+y=-1
butalik [34]

Answer:

{x,y} = {5,6}

Step-by-step explanation:

// Solve equation [1] for the variable  x

 [1]    x = y - 1

// Plug this in for variable  x  in equation [2]

  [2]    2•(y -1) - y = 4

  [2]    y = 6

// Solve equation [2] for the variable  y

  [2]    y = 6

// By now we know this much :

   x = y-1

   y = 6

// Use the  y  value to solve for  x

   x = (6)-1 = 5
