Spinning a 4-section spinner twice can be described as which type of event?
vfiekz [6]

The <em>correct answer</em> is:


A) It is an independent event. The outcome of the second spin is unaffected by the outcome of the first spin.


Explanation:


Simple events are events in which one experiment happens at a time and there is only one single outcome. Since we are spinning the spinner twice, this is not a simple event.


Dependent events are events in which the outcome of one affects the other. This is not the case here.


Independent events are events in which the outcome of one event does not affect the probability of the next event. The result of the first spin will not influence the result of the second spin, so these are independent events.

Maths functions question
il63 [147K]

Answer:

-4 < x < 3

Step-by-step explanation:

<u>Information from Parts 1-4 of the same question:</u>

brainly.com/question/28193969

  • f(x)=-x+3
  • g(x)=x^2-9
  • A = (3, 0)

<u>Information from Parts 5-8 of the same question:</u>

brainly.com/question/28193994

  • D = (-4, 7)

<h3><u>Part (9)</u></h3>

The values of x for which g(x) < f(x) are the values of x between the points of intersection of the two functions:  points D and A.

From part (2) of the question, we found that A = (3, 0).

From part (5) of the question, we found that D = (-4, 7).

Therefore, the values of x for which g(x) < f(x) are -4 < x < 3.

In interval notation this is: (-4, 3).
