Ipatiy [6.2K]

Answer:

$2(3x - 7) = - 4(x + 5) + 3 \\ 6x - 14 = - 4x - 20 + 3 \\ 6x + 4x = - 20 + 3 + 14 \\ 10x = - 3 \\ \\ x = \frac{ - 3}{10} \\ \\ x = - 0.3$

The amount of time needed for a certain machine to process a job is a random variable with mean EXi = 10 minutes and Var(Xi)=2 m

lana66690 [7]

Answer:

0.98732

Step-by-step explanation:

Given that :

Mean = 10 minutes

Variance = 2 minutes

For less than equal 40 jobs

Mean (m) = 40 * 10 = 400 minutes

Variance = 2 * 40 = 80 minutes

Standard deviation (s) = √variance = √80

Converting hours to minutes

X = 60 * 7 = 420 minutes

P(X≤ 420) :

Z = (x - m) / s

P(X≤ 420) :

Z = (420 - 400) / √80

Z = 20 / √80 = 20 / 8.9442 = 2.236

P(Z ≤ 2.236) = 0.98732
