joe spend 1 1/3 hours studying for his math test. randy studied for 1/2 the amou t the time that joe did. what fraction of an hour did randy spend studying
​

Answers

Answer 1

Step-by-step explanation:

Lets convert 1 1/3 into improper fraction.

[tex]1 \frac{1}{3} = \frac{1 \times 3 + 1}{3} \\ = \frac{4}{3} [/tex]

Since Randy studied half the above time,

Randy Studied:

[tex] \frac{1}{2} \times \frac{4}{3} \\ = \frac{1 \times 4}{2 \times 3} \\ = \frac{4 \div 2}{6 \div 2} \\ = \frac{2}{3} hours[/tex]

To determine how many students at a middle school bring their lunch from home, all the students on one school bus are surveyed. identify if this is BIASED OR UNBIASED. Explain your reasoning!!

Answers

I would say biased because only the student on one school bus are being surveyed. While there are other buses of kids and kids who get dropped off. So they are in a way discriminating those other kids. Just surveying one bus of kids out of all the other kids won’t get the correct number of students who bring their lunch from home.
