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
It depends on how long there arms are I think
So pretend weekend calls is x and weekday calls are y.
the formulas is x + y = 610
0.07x + 0.08y = 48.05
So, x = 610 - y
Then, substitute x into the second equation.
0.07(610 - y) + 0.08y = 48.05
42.7 - 0.07y + 0.08y = 48.05
0.01y = 5.35
y = 535
Then substitute y into the first equation.
x + 535 = 610
x = 75
Just to be sure, substitute x and y into the second equation.
0.07(75) + 0.08(535) = 48.05
5.25 + 42.80 = 48.05
48.05 = 48.05
So, on weekends, he used 75 minutes.
On weekdays, he used 535 minutes.
Answer:
this doesn't make sense, but it depends how big the wall is I guess
