Answer:
Quadrant 2
Step-by-step explanation:
Convert radians to degrees
7pi/8(180/pi)
1260/8=157.5
157.5 degrees would fall into quadrant 2
Answer: See description below.
The residuals are the differences between the predicted values and the actual values. You will need to make a scatter plot of each difference.
Here are the five points that you will need to plot:
20 - 21 = -1 (1, -1)
17 - 16 = 1 (2, 1)
9 - 10 = -1 (4, -1)
6 - 5 = 1 (5, 1)
2 - 2 = 0 (6, 0)
180-50=130
x-y=130
x+y=50
2x=180
x=90
90+y=50
y=50-90
y=-40
The probability of drawing an even number is 4/8 = 1/2 since there are 4 even cards (2,4,6,8) out of 8 total.
After the first draw, the card is put back. There are still 8 cards in the deck. There are 2 cards that are larger than 6. Those numbers are 7 and 8. So the probability of picking a card larger than 6 is 2/8 = 1/4
Multiply the two individual probabilities to get
(1/2)*(1/4) = (1*1)/(2*4) = 1/8
The final answer is 1/8
