A researcher who is studying voting habits chose 650 registered voters at random, shortly after the 2016 presidential election. Of these voters, 74% said they had voted in the election. However, election records show that only 58% of registered voters voted in the election. Which of the following statements is true? Seventy-four percent is a sample and 58% is a population. Seventy-four percent and 58% are both statistics. Seventy-four percent is a statistic and 58% is a parameter. Seventy-four percent is a parameter and 58% is a statistic. Seventy-four percent and 58% are both parameters.

Step-by-step explanation:

A statistic is a percentage of a sample.

A parameter is a percentage of a population.

So 74% is a statistic and 58% is a parameter.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
