1. (quality control) suppose that when a fabric production process is in control, the number of flaws in a piece of fabric of length l yards has a poisson distribution with mean (.02)l. suppose that periodically a length of fabric of 10 yards is inspected and the flaws are counted. if there are too many flaws, say more than k, the process will be presumed to be out of control, and stopped, and fixed. what should k be such that the probability of stopping the process when it is really in control is at most 5%? (again, a little bit of trial and error, the value of k is small.)

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

radha is now 5 years old

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !

step-by-step explanation:

d would equal 12

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24
