Iesha’s quality-control manager told her she must have 97% of her clocks functioning properly. she found a report that said 6 out of 300 clocks tested were not working properly. kiesha predicts that she will have enough working clocks to the manager. which statements are true about kiesha’s prediction? check all that apply.
kiesha’s experimental probability is 1/30.
kiesha will have more than 97% of the products working.
kiesha will not meet 97% because more than 3% of her clocks will be broken.
kiesha’s experimental probability is 1/50.
when the inventory is 4000 clocks, the prediction is that 3920 clocks will work.

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
