In a group of 31 pupils, 4 play the flute only. 14 play the piano only. 7 play neither instrument. A student is selected at rand

solmaris [256]

Answer:

probability the student plays both instruments is [ $\frac{6}{31}$ ]

<h2> <u>Explanation</u>:</h2>

students who play both instruments = total students - flute players - piano players - students who play neither instruments

students who play both instruments

→ 31 - 4 - 14 - 7

→ 6 students play both instruments.

probability:

<h2>→ $\boxed{\frac{students- who -play- both- instruments}{total -students} }$ </h2><h2>→ $\boxed{\frac{6}{31} }$ </h2>

Solving rational equations<br><br> solve for x: 3/x-4=7/x

KIM [24]

Solving the rational equation $\frac{3}{x-4}=\frac{7}{x}$ the value of x is 7

Step-by-step explanation:

We need to solve rational equation: $\frac{3}{x-4}=\frac{7}{x}$ and find value of x.

Solving:

$\frac{3}{x-4}=\frac{7}{x}$

Cross multiplying:

$3(x)=7(x-4)\\Simplifying:\\3x=7x-28\\3x-7x=-28\\-4x=-28\\x=-28/-4\\x=7$

So, value of x = 7.

Solving the rational equation $\frac{3}{x-4}=\frac{7}{x}$ the value of x is 7

Determine which function has the greatest rate of change as x approaches infinity.

Mekhanik [1.2K]

Answer: h(x) = 3*x^2 - 7*x + 8

Step-by-step explanation:

The rate of change of a function is equal to the derivate:

remember that a derivate of the form:

k(x) = a*x^n is k'(x) = n*a*x^(n-1)

Then we have:

f(x) = 2*x - 10

f'(x) = 1*2* = 2

g(x) = 16*x - 4

g'(x) = 1*16 = 16

h(x) = 3*x^2 - 7*x + 8

h'(x) = 2*3*x - 1*7 = 6*x - 7

So the only that increases as x increases is h(x), this means that the greates rate of change as x approaches inffinity is the rate of change of h(x)

What is the product?<br><br> 2x(x – 4)

sashaice [31]

Keywords:

<em>Product, factors, polynomial, distributive property </em>

For this case we must find the product of two factors of a polynomial. To do this, we must apply the distributive property, which states: $a (b + c) = ab + ac.$

So:

$2x (x - 4) = 2x * x-2x * 4\\2x (x - 4) = 2x ^ 2-8x$

Thus, the product of $2x (x - 4)$ is: $2x ^ 2-8x$

Answer:

The product of $2x (x - 4)$ is: $2x ^ 2-8x$
