Answer:

The new ordered pair for point Q' are: Q' (5, 7)

Step-by-step explanation:

Q = (-5, 7)

The rule of translation is:

(x, y) → (-x,y)

According to this rule, the value of x is multiplied by -1, and the value of y remains the same.

Thus,

P(x, y) → P'(-x,y)

Q (-5, 7) → Q' (-(-5), 7) → Q' (5, 7)

Thus, the new ordered pair for point Q' are: Q' (5, 7)

Find the real and/or imaginary solutions by factoring

Leya [2.2K]

Here is number 7:
${x}^{2} - 11x = - 24 \\ {x}^{2} - 11x + 24 = 0 \\ (x - 3)(x - 8) = 0 \\ x = 3 \: and \: 8$
Here is number 8:

$3 {x}^{3} + 3 {x}^{2} = 27x \\ 3 {x}^{3} + 3 {x}^{2} - 27x = 0 \\ 3x( {x }^{2} + x - 9) = 0 \\ x = 0 \: and \: two \: more \: solutions \: shown \: below.$
Use the quadratic formula to find the other two solutions:

$x = \frac{ - 1 + - \sqrt{ {1}^{2} - 4(1)( - 9) } }{2(1)} \\ x = \frac{ - 1 + \sqrt{37} }{2} \\ x = \frac{ - 1 - \sqrt{37} }{2}$

This person has a 75% chance of a full recovery. Is this classical probability, empirical or subjective

RideAnS [48]

Answer:

Subjective probability

Step-by-step explanation:

At first we should know the following:

Classical probability ⇒ when there are n equally likely outcomes.

Subjective probability ⇒ is based on whatever information is available.

Empirical probability ⇒ when the number of times the event happens is divided by the number of observations.

So, according to the previous definitions:

This person has a 75% chance of a full recovery

There is no equally likely outcomes, and the percentage of full recovery is based on the information available about the person and also it is based on educated guess.

So, this is Subjective probability
