You would take 280-105=175 miles away and take 105 and divide that by your time 1.5 too get 70 mph
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
Putting it like 7*t*s*3*r*t and multiplying like terms using the commutative property, we get 21*t²*s*r or 21rst²
No the don't add up to one eighty I'm pretty sure if not tell me
Answer:
I think the answer for that question is c
