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

Answer:

a = 4, b = - $\frac{3}{2}$

Step-by-step explanation:

Given

$\frac{8-3\sqrt{2} }{2}$ = a + b $\sqrt{2}$ ( multiply both sides by 2 to clear the fraction )

8 - 3 $\sqrt{2}$ = 2a + 2b $\sqrt{2}$

For the 2 sides to be equal , then

2a = 8 ( divide both sides by 2 )

a = 4

and

2b = - 3 ( divide both sides by - 2 )

b = - $\frac{3}{2}$

Subtract 9 from 10. Multiply this different by 3 square this product

BigorU [14]

Answer:

Step-by-step explanation:

Given: Subtract 9 from 10. Multiply this difference by 3, square this product.

Now, lets simplify it.

$[(10-9)\times 3]^{2}$

Using PEDMAS rule to solve it

First working on Parenthesis

= $[(1)\times 3]^{2}$

Opening the parenthesis

= $[1\times 3]^{2}$

= $[3]^{2}$

= $9$

∴ Answer is 9.
