70 students at a school were asked to complete a survey about the location of their next field trip. 28 students chose the zoo 33 students chose the amusement park. the remaining students did not complete the survey . which expression gives the percent of survey participants who chose the zoo?

Info:

Voted - 70

Voted for zoo - 33

Calculating percentage:

(33/70) * 100 = x

0,47 * 100 = x

47% approx.

Notes:

When finding a percentage, you create a fraction, which we can call a rate, containing the number of actions on top (numerator), and the total of actions below (denominator). Afterwards, we multiply the answer by 100 and round the answer to the closest number, which will be our percentage.

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.

the aswere is the one with all 8's and the second one is with the 10,8 and 6
