1) Distance = speed x time
time = distance/speed

time = 8054/715 = 11.26 hours or 11 h and 15 minutes (0.26 x 60 = 15.6)

2) The mode in a statistical series is the number that is repeated most or in short the highest frequency. In you example we notice that 12 is repeated twice, whereas the others are not repeated. Then the mode is 12.

3) The cost of each game = $17.99, so with his $65 he can buy:
65/17.99 = 3.61 . Obviously he can't buy 0.61 game, then he can buy 
only 3 games (3 x 17.99 =  $53.97) and keep in his pocket :
65 - 53.97 = $11.03

Find an equation of the circle whose diameter has endpoints (2,3) and (-4,5)
natka813 [3]

Answer:

(x+1)² + (y-4)² = 10

Step-by-step explanation:

The diameter of a circle has the endpoints at (2,3) and (-4,5).

Therefore, the length of the diameter is given by

\sqrt{(2-(-4))^{2}+(3-5)^{2}} = 2\sqrt{10}

Hence, the radius of the circle is √10.

Now the midpoint of the line joining (2,3) and (-4,5) will be the center of the straight line.

Hence, the center will be at (\frac{2-4}{2},\frac{3+5}{2}) =(-1, 4)

Therefore the equation of the circle is  

(x+1)² + (y-4)² = (√10)²

⇒  (x+1)² + (y-4)² = 10 (Answer)
