4.) The time X (minutes) for a lab assistant to prepare the equipment for a certain experiment is believed to have a uniform dis
Jet001 [13]

Answer:

P(35-2 < X 35+2) = P(33< X< 37)= P(X

And using the cumulative distribution function we got:

P(35-2 < X 35+2) = P(33< X< 37)= P(X

The probability that preparation is within 2 minutes of the mean time is 0.134

Step-by-step explanation:

For this case we define the following random variable X= (minutes) for a lab assistant to prepare the equipment for a certain experiment , and the distribution for X is given by:

X \sim Unif (a= 20, b =50)

The cumulative distribution function is given by:

F(x) = \frac{x-a}{b-a} , a \leq X \leq b

The expected value is given by:

E(X) = \frac{a+b}{2} = \frac{20+50}{2}=35

And we want to find the following probability:

P(35-2 < X 35+2) = P(33< X< 37)

And we can find this probability on this way:

P(35-2 < X 35+2) = P(33< X< 37)= P(X

And using the cumulative distribution function we got:

P(35-2 < X 35+2) = P(33< X< 37)= P(X

The probability that preparation is within 2 minutes of the mean time is 0.134

HELP AGIAN PLEASEEEEEEEEEEEEEE
marusya05 [52]

Step-by-step explanation:

y=mx+b

6 -8

9 -7

- 8 = 6m + b \\  - 7 = 9m + b \\   - 7 + 8 = 9m - 6m \\  3m= 1 \\ m =  \frac{1}{3}  \\

- 8 = 6 \frac{1}{ 3}  + b \\  b =  - 8 - 2 \\ b =  - 10 \\ y = 0.333x - 10 \\ y =  \frac{x}{ 3 }  - 10
