The following tables gives the distribution of items of production and also the relatively defective items among them according to size groups. Find the correlation coefficient between size and defect in quality and it's probable error. The no of items are 200,270,340,360,400,300 while the no of defective items are 150,162,170,180,180and114 ​

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
