<u>Answer:</u>
The correct answer option is 48.
<u>Step-by-step explanation:</u>
In the given experiment, three events take place which include rolling a die, flipping a coin and spinning a spinner.
The possible outcomes of each of these events are as follows:
Rolling a die - 6
Flipping a coin - 2
Spinning a spinner - 4
Therefore, by multiplying their possible outcomes, we can find the number of elements in the sample space of this environment.
Number of elements = 6 × 2 × 4 = 48
Answer:
Response Bias
Explanation:
Response bias occurs when participants in a research study have a tendency to reply falsely to research surveys. It is mainly caused by poor survey design, example ambiguous use of likert scale in survey questions. In this case, participants have a pre-recorded response to survey questions which would not accurately represent the population as participant replies are likely to be false.
Answer: C
<u>Step-by-step explanation:</u>
(x - 3)² = 0
(x - 3)(x - 3) = 0
x(x - 3) -3(x - 3) = 0
x² - 3x -3x + 9 = 0
x² - 6x + 9 = 0
Answer:
Because they're set's of positive and negative numbers
