A manufacturing plant producing electric motors has two production lines. In a typical day, 85% of the motors are produced in la

ne I, 15% in lane II. Past quality control study shows the probability that a randomly selected motors be defective is 12% if produced by line I, and 4% if produced by line II. A randomly selected motor from this manufacturing plant is tested for possible defect. Find the probability that the selected motor is produced by line 1 if the test shows that the selected engine is defective.

Answer:

1. 23/20 miles, 2. 7/20 miles

Step-by-step explanation:

1. Total distance = 3/4 + 2/5

= (3*5)/(4*5) + (2*4)/(5*4)

= 15/20 + 8/20

= 23/20

= 1 3/20 miles

2. Difference between walked miles and jogged miles = 3/4 - 2/5

= 15/20 - 8/20

= 7/20 miles

Vadim26 [7]

Answer:

(7,2)

Step-by-step explanation:

x + y = 9 + 2x - 3y = 8 is really two equations, and you should show this by separating x + y = 9 from 2x - 3y = 8 through the use of a comma, or the word "and," or through writing only one equation per line.

Here you have the system of linear equations

 x +   y =  9

2x - 3y = 8.

Let's solve this system by elimination.  Mult. the 1st eqn by 3, obtaining the system

3x + 3y = 27

2x - 3y =    8

-------------------

5x = 35, so that x = 7.  Subbing 7 for x in x + y = 9, we get 7 + y = 9, indicating that y = 2.

Thus, the solution to this system of equations is (7,2).

The Walking Club is one of the after-school activities at Jefferson Middle School.

You first need to know how much miles it takes on the trail. Then you look 20 x 3 is one hour. And if the 3 group said it takes 2 hours waking for them its like this, the first group takes one hour to go thru the trail, but the second group takes and hour and half the 3 group takes 2 hours.

I wish this helps. :)
