Answer:
Step-by-step explanation:
Overall students=50
35 -> j.
25 -> r.
16-> j.+r.
35-16=19 students joined j.
25-16=9 joined r.
50-19+9
50-28=22
The answer is 22
It would be nice if you could give me the brainliest rating. Best of luck!
The correct response is D; we can treat the survey as one involving a single variable, responding with either "yes, I attended more than 4 games" or "no." Given the random survey of 10 students meets the randomization criterion and that their responses are independent, options B and C can be dismissed. However, since only 10 students were surveyed, the confidence interval will not be narrow. As per Statistical Solutions, a minimum of 10 subjects per variable is essential for regression analysis. If the query concerns the number of games each student attended, the potential variables increase; conversely, if it solely asks, “Did you attend more than 4 games?”, then we only consider a single variable, making 10 students sufficient.
Response
The first diagram displays angles 1 and 2 as vertical angles.
Clarification
In all four diagrams, the initial one illustrates the vertically opposite angles.
Angles 1 and 2 are classified as vertically opposite because they face each other.
These angles maintain equal measurement when two lines intersect, resulting in four angles where two pairs of vertically opposite angles are formed.
In contrast, all other figures depict angles 1 and 2 as adjacent angles.
