now subtract \frac{1}{2} from each side 
x= -0.1

Lady bird [3.3K]

Suppose that every student in a discrete mathematics class of 25 students is a sophomore, a junior, or a senior: FALSE

<h3>What is a sophomore?</h3>
  • A sophomore in the United States is a student in their second year at an educational institution, usually a secondary school or a college or university, but also other types of post-secondary educational institutions.
  • A sophomore in high school is equivalent to a tenth-grade or Class-10 student.
  • In sports, a sophomore is a professional athlete in their second season.

As in the description, it is given that a sophomore in high school is equivalent to a tenth-grade or Class-10 student.

So, the above-given statement becomes false as it says that every student is a sophomore but the class has juniors and seniors.

Therefore, the statement "suppose that every student in a discrete mathematics class of 25 students is a sophomore, a junior, or a senior" is FALSE.

What is the value of 6 in 4.769
mixer [17]
<span>The <u>correct answer</u> is:

6/100.

Explanation<span>:

We look at place value to answer this. The digit in front of the decimal is the ones; directly after the decimal we have the tenths; behind this we have the hundredths; and behind this we have the thousandths.

6 is two places behind the decimal; this is the hundredths place. This means it is six hundredths, or 6/100.</span></span>
