Answer:
Follows are the responses to the given question:
Step-by-step explanation:
Please find the attached file for the complete question:
For point A:
The amount of money being spent appears to rise for those 25 students as the number of hours increases. This is evident from the plot of scattering as well as the best line.
For point B:
Its number of hours spent as well as the amount of money spent were also positive for such 25 students.
For point C:
Also with a line that fits best, we will indeed predict that only an 8-hour student would spend about $22.
All these are seen in a direct line drawn from the x-axis where x=8 fits this same best line and a horizontal line is drawn between that axis and the Y-axis is drawn.
Answer:
The intercept is 5.
Step-by-step explanation:
Since we already have the slope of -1/6, we can use that and either point in point-slope form to get the equation in slope-intercept.
y - y1 = m(x - x1)
y - 3 = -1/6(x - 12)
y - 3 = -1/6x + 2
y = -1/6x + 5
Therefore, b= 5
4(10-8)-3
4(2)-3
5
so the answer is 5
Answer:
1.5625%
Step-by-step explanation:
P(correct) = 1/4
Since all the attempts are independent, probability of all three correct is:
¼ × ¼ × ¼
1/64
1/64 × 100
