Will cash bonuses speed the return to work of unemployed people? a state department of labor notes that last year 68% of people who filed claims for unemployment insurance found a new job within 15 weeks. as an experiment, this year the state offers $500 to people filing unemployment claims if they find a job within 15 weeks. the percent who do so increases to 77%. what flaw in the design of this experiment makes it impossible to say whether the bonus really caused the increase? explain.

People by hearing about the bonus of 500 US dollar news had purposely resigned and filed for unemployment.

Step-by-step explanation:

The flaw in the design was basically no restrictions for people who deliberately resign from their companies to get bonuses.If one needy person after struggle get employment he might not risk his job for 500 US dollars.

In the mean while people with experience and currently working in the different companies  resigned from their jobs,filling unemployment claims to get bonus and due to experience as well as restoring their jobs easily.So percent Increase is only because of those people who want to earn a bonus.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

y = i/2 xtnop + (3i/2 tnop+ 1)
