The variable z is inversely proportional to x. when x is 5, z has the value 0.8. what is the value of z when x= 12?

Given that, the variable z is inversely proportional to x.

So, we can set up an equation as following:

z * x = k Where k is constant of variation.

Also given that, when x = 5 then z =0.8.

Next step is to plug in these values in the above equation to get the value of k.

So, 0.8 * 5 =k

k = 4

So, the equation become : z* x = 4.

Now we need to find the vaue of z when x=12. Hence,

z * 12 = 4

z = Divided each sides by 12 t isolate z.

z = 0.3 Rounded to tenth.

So, z= 0.3

Hope this helps you !

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
