A quality-assurance worker wants to systematically sample 120 glass jars each day from a conveyor belt in a factory that puts out 3,600 jars each day. If the worker will select every kth jar, what is the best value of k for the worker to use? Enter a whole number.

Answers

Answer:

The best value of k for the worker to use is 30.

Step-by-step explanation:

Sample of 120 jars from a set of 3,600.

If the worker will select every kth jar, what is the best value of k for the worker to use?

The best case would be starting at 0 and ending at 3600, finding 120 values, which means that k is given by the division of 3600 by 120. So

[tex]k = \frac{3600}{120} = \frac{360}{12} = 30[/tex]

The best value of k for the worker to use is 30.

If x represents the age of the father and

then the statement for 'present age of

age of the son' in terms of a
mathematical equation is *​

Answers

Answer:

x = 5+6y

Step-by-step explanation:

Let x represents the age of the father and  y represents the present age of the son.

ATQ,

The present age of  the father is 5 more than 6 times the  age of the son. We can write it in the form of equation as follows :

6 times the  age of the son means 6y. So,

x = 5+6y

Hence, the mathematical equation is "x = 5+6y".
