A group of students is taking a CPR course. The total cost for the course is $275. The room in which the course will be held can hold a maximum of 25 people, including the instructor. What is the minimum number of students needed to take the course so that the cost per student will be less than $15? A. 11 B. 17 C. 18 D. 19

Answers

Answer 1

Answer: 25 people = 24 students + 1 instructor;
$275 / x < $15
x > $275 : $15
x > 18.3333
x = 19
Answer:
The minimum number of students is: D ) 19.

Answer 2

Answer:

Answer:

The answer is the option D

the minimum number of students will be $19$

Step-by-step explanation:

Let

x-------> the minimum number of students

we know that

$15x\geq 275$ ------> inequality that represent the situation

The domain of the inequality is the interval-------> $[0,24]$

Solve for x

Divide by $15$ both sides

$x\geq 275/15\n x\geq 18.33$

the minimum number of students will be $19$

Answers

Simplify 35x to 3x5

3x5−15=65x+12

2. Simplify 65x to 6x5
3x5−15=6x5+12

3. Multiply both sides by 5
3x−75=6x+60

4. Subtract 3x from both sides
−75=6x+60−3x

5. Simplify 6x+60−3x to 3x+60
−75=3x+60

6. Subtract 60 from both sides
−75−60=3x

7. Simplify −75−60 to −135
−135=3x

8 .Divide both sides by 3
−1353=x

9. Simplify 1353 to 45
−45=x

10. Switch sides
x=−45

What are the coefficients in the polynomial 5x^2 + 2x - 4?A: 5, 2
B: -5, -2
C: 5, 2, -4
D: 5, -2, -4

Answers

The solution is, A) 5, 2 are the coefficients in the polynomial 5x^2 + 2x - 4.

What are Polynomials?

Polynomials are sums of k-xⁿ terms, where k can be any number and n can be any positive integer.

here, we have,

given that,

the polynomial is : 5x^2 + 2x - 4

now, we have to find the coefficients in the polynomial 5x^2 + 2x - 4

we know that,

a coefficient is a multiplicative factor in some term of a polynomial, a series, or an expression; it is usually a number, but may be any expression. When the coefficients are themselves variables, they may also be called parameters.

and. we have,

a variable is a symbol that represents a mathematical object. A variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set.

so, we get,

a coefficient is the number in front of the variable,

here, 5, 2 are the coefficients.

and the variable is x.

Hence, The solution is, A) 5, 2 are the coefficients in the polynomial 5x^2 + 2x - 4.
