Answer:
First question is 109
Second question is 45, but I guess it's a typo with 145.
Answer:
-7.333
Step-by-step explanation:
Using the mean <u>formula and it's interpretation</u>, it is found that:
1. The mean is 7.52.
2. If we were to give this quiz to more and more students, the mean score for these students would approach 7.52.
The mean of a discrete distribution is given by the <u>sum of each outcome divided by it's respective probability</u>.
Hence, in this problem, according to the <u>distribution given</u>, the mean is:

The mean is 7.52.
The <em>interpretation </em>is that over many trials, the mean would approach 7.52.

The northern hemisphere is experiencing winter because the earth's axis is tilted so that the northern hemisphere doesn't receive direct sunlight. The changing of the seasons is determined by whether a place is experiencing direct sunlight or indirect sunlight due to the earth's tilt.
Answer: y= -3/2x
Explanation:
3x+ 2y- 6
→ 2y= -3x+ 6
→ y= -3/2x+ 3
Parallel to y= ax+ b is to have the same slope (ax) and have a different y- intercept.
For this equation, y= -3/2x + 3, it is y= -3/2x because the line has to pass through point (0,0).
