Surgery Satisfaction Survey
Zinaida [17]

Answer: D) 14.3%

Step-by-step explanation:

Conditional probability formula:

P(B |\text{given that A}) =\dfrac{P(A\ and\ B)}{P(A)}

So, The probability he or she was dissatisfied, given that he or she had hip surgery = \dfrac{\text{Number of persons are dissatisfied and has hip surgery}}{\text{Total persons have hip surgery}}

From the table, the number of persons who are dissatisfied and has hip surgery = 15

Total persons have hip surgery = 105

Required probability = \dfrac{15}{105}\approx0.143

In percent, Required probability = 14.3%

Correct option D) 14.3%

What is the solution of the linear-quadratic system of equations? { y = x 2 + 5 x − 3 y − x = 2
svp [43]

The two solutions for the system of equations:

y = x^2+ 5x - 3

y - x = 2

Are:

(-5, -7) and (1, -1)

<h3>How to solve the system of equations?</h3>

Here we have the following system of equations:

y = x^2+ 5x - 3

y - x = 2

We can replace the first equation into the second one to get:

(x^2+ 5x - 3) - x = 2

x^2 + 4x - 3 = 2

x^2 + 4x - 3 - 2 = 0

x^2 + 4x - 5  = 0

Using the quadratic formula, we will get the solutions:

x = \frac{-4 \pm \sqrt{4^2 - 4*1*-5} }{2} \\\\x = \frac{-4 \pm 6}{2}

The two solutions are:

x = (-4 - 6)/2 = -5

x = (-4 + 6)/2 = 1

To find the values of y, we can evaluate the linear equation:

when x = -5

y - (-5) = -2

y + 5 = -2

y = -2 - 5 = -7

So one solution is (-5, -7)

when x = 1

y - 1 = -2

y = -2 + 1 = -1

The other solution is (1, -1)
