Answer:

a) 0.970225

b) 0.999775

c)  0.000225

Step-by-step explanation:

probability of one system not working =1-0.985=0.015

a)

probability of one system is 0.985 then

Probability of both system = 0.985 * 0.985= 0.970225

b)

probability of one of system fail is = 1 - 0.985

                                                         =0.015

Therefore

probability of both system failing =0.015 * 0.015 =0.000225

probability at least one system function satisfactorily = 1- 0.000225

                                                                                        = 0.999775

c)

If both system are fail then probability is 0.000225

Write the y-intercept of the graph of 9x + 6y = 27
stealth61 [152]

Answer:

y= −3 /2 x+ 9/ 2

Step-by-step explanation:

Let's solve for y.

9x+6y=27

Step 1: Add -9x to both sides.

9x+6y+−9x=27+−9x

6y=−9x+27

Step 2: Divide both sides by 6.

6y /6=−9x+27 /6

y= −3 /2 x+ 9/ 2

Answer:

y= −3 /2 x+ 9/ 2
