Answer:
3 hours on the city roads and 4 hours on the other roads
Step-by-step explanation:
580 (total miles driven) - 400 (4 hours of driving 100km/h) = 180 (miles left)
180 (miles left to drive) / 60 (km/h) = 3 (hours driven at the speed of 60km/h)
I hope this helps :)
Answer:
Step-by-step explanation:
Given that x = no of movies high school students watched is N(6.8, 1.8)
Sample size = 36 and hence std error = 1.8/6 = 0.3
(two tailed test)
Mean difference = 6.2-6.8 = -0.6
Test statistic z = -0.6/0.3= -2
p value = 0.02275
Since p <0.05 we reject H0.
There is evidence to show that college students watch fewer movies a month than high school students
Answer:
the operation we use to convert quarts to liters : multiply
Step-by-step explanation:
One quart is approximately equal to 0.95 liter
Here quart is the larger unit and liter is the smaller unit
To convert larger unit to smaller unit we multiply
given that 1 quart = 0.95 liter
2 quart = 2 times 0.95
3 quart = 3 times 0.05
so to convert quart of liter we multiply
the operation we use to convert quarts to liters we multiply by 0.95
