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.

The complete question is given below:
Suppose that every student in a discrete mathematics class of 25 students is a sophomore, a junior, or a senior. Is the following statement true or false:
"The course must have at least five sophomores, or at least 20 juniors, or at least 10 seniors."
Answer:
1. 3-4-5 method
2. Rope method
3. Optical square method
Step-by-step explanation:
1. You'll need a measuring tape, two range poles, pegs, and three people.
The first person holds the zero mark between their thumbs and fingers, the second person holds the 3m mark on the tape between their thumbs and fingers, and the third person holds the 8m. When all sides of the rope are stretched, a triangle is created, and an angle near one is a right angle.
2. Wrap one loop of the rope around peg A with a peg through the other loop, draw a circle on the ground, place pegs B and C where the circle crosses the base line, and place peg D half way between pegs B and C, allowing pegs D and A to form lines perpendicular to the base line, forming a right angle.
3. Single and double prismatic squares are basic devices used to measure correct angles.
Answer:
x=6
XY=24 units
YZ=18 units
Step-by-step explanation:
we have that
Y is between X and Z
substitute the given values and solve for x
therefore
Answer:
Step-by-step explanation:
Number of boys = 12
Number of girls = 18
Total number of students = 12 + 18 = 30
Probability refers to chances of occurrence of any event.
Probability = Number of favorable outcomes ÷ Total number of possible outcomes
To find P(Senior | Boy), use
P(Senior and Boy) =
P(Boy) =
So,
P(Senior | Boy) = P(Senior and Boy) ÷ P(Boy) =
