Answer:
C. The principal randomly selects homeroom classes and surveys each student in the chosen classes.
Step-by-step explanation:
Middle school is 6-8th. Surveying only the eighth-grade students won't give a representative sample of the whole school only the eighth-graders. Option A is incorrect.
Surveying only the students in detention represents a very small amount of students compared to the school, therefore it is not a representative sample. Option B is incorrect.
Yet again, the students in the math club is a small amount of students compared to the school. It does not represent the entire, or majority of the population. Option D is incorrect.
Picking students from homeroom classes and surveying each will give a wider variation of opinions from each grade and therefore a representative sample. Option C is the correct answer.
You put your like terms together so, you do the opposite of addition which is subtraction.
So you subtract 6 on each side, and -28-6 is -34
so now you have 2n=-34 and since 2 has the variable you have to divide by 2 on each side so how you have n= -34÷2
so 34÷2= 17 and since the terms are unlike you have to put a negative sign
so n=-17
Answer:
<h2>6 feet</h2>
Step-by-step explanation:
3 x 2 = 6
The Fundamental Theorem of Algebra is one of the most common and most essential theorem in mathematics which states that "any polynomial degree of n will also have n roots". The degree of the equation is the highest exponent that the terms has.
In this item, if we perform the operation then, we will have a degree of 3. Therefore, the number of roots for this polynomial function is 3.
Answer:
$27.90
Step-by-step explanation:
Due the Laura and her sister being 2 people, we will be dividing the total by 2.
So,
55.80 ÷ 2 = $27.90
Both Laura and her sister will be paying $27.90 to split the amount evenly.
