Answer:
24.8 mins
Step-by-step explanation:
Time > timemark > frequency
0 – 10 > 10/2 = 5 > 5
10 – 20 > (10+20)/2 = 15 > 15
20 – 30 > (20+30)/2 = 25 > 13
30 – 40 > (30+40)/2 = 35 > 10
40 – 50 > (40+50)/2 = 45 > 7
The mean time for the 50 people is given by:
Mean = summation (mid time x frequency) / total frequency
Mean = [5x5 + 15x15 + 25x13 + 35x10 + 45x7] / 50
Mean = [25 + 225 + 325 + 350 + 315] / 50
Mean = 1240 / 50
Mean = 24.8 mins
Answer:
30 min
Step-by-step explanation:
She takes 45 minutes to run 6 miles.
Lets simplify this. If we divide by 3, then we know that:
She takes 15 minutes to run 2 miles.
Therefore, to find the amount of time it takes to run 4 miles, we just multiply 15 by 2.
Therefore it takes her 30 mins to run 4 miles.
Hi,
c(x) is a linear function, if you graph it, you obtain a straight line.
The slope is the coefficient of x, therefore the slope is 2.
When the ride starts (x = 0), the start cost is 4 dollars (or whatever the currency is), then every minute spent on the moving taxi, as many as 2 dollars need to be paid to taxi driver.
I hope these help.
