Answer:
Step-by-step explanation:
Distribute:
Combine all like terms:
You know ABC is isoceles, so AB = BC and BC = 2.5 cm.
That means that the scale factor is KL/BC = 2
So JL = 2AC = 8 cm
The coordinates of points A, B, and C are (5, 4), (–2, 1), and (4, –4), respectively. Which point, B or C, is closer to point A?

Answer:
The distance between two points (x1,y1) and (x2,y2) = √((x1-x2)2+(y1-y2)2) Distance between A and B = √((5--2)2+(4-1)2) = √(72+32) = √(49+9) = √58 = 7.62 Distance between A and C = √(12+82) = √65 = 8.06 Point B is closer to A. Another method to solve this problem is to draw the points on a graph paper and measure distance with a ruler.
The answer is 47.5.
The equation for this problem is:
60(H) + (M) divided by 2.
Plug the numbers of the time in the equation,
60(3) + (25) / 2
180 + 25 / 2 = 205/2
205/2 = 102.5 (Smaller Angle)
Then you calculate the angle between 12 and the Minute hand 25.
0m= 6M
0m = 6(25)
0m= 150
Final step is to subtract the hour angle by the minute angle.
H(102.5)-(150)= -47.5 or 47.5 degrees

Answer: The p-value is 0.154.
Step-by-step explanation:
Since we have given that
We claim that
Null hypothesis :
Alternate hypothesis :
Population mean = 20 hours
Sample mean = 18.5 hours
Sample standard deviation = 4.3 hours
Sample size n = 35
So, test statistic would be
So, the p value would be 0.154.
Hence, the p-value is 0.154.
