Answer:
Number of courses would best be considered a discrete variable and drive time would be considered a continuous variable.
Step-by-step explanation:
Discrete variable:
Countable amounts(0, 1, 2, 3,...)
Continuous variables:
Can be decimal values.
In this question:
The number of courses is a countable amount(0,1,2,3,...), you cant take half a course, for example, so it is discrete. Otherwise, drive time accepts half minutes, for example, 10.5 minutes, so is continuous.
Number of courses would best be considered a discrete variable and drive time would be considered a continuous variable.
Answer:
Step-by-step explanation:
subtract the 2x to get 3y = -2x+6
Divide By 3 to get y = (-2/3)x + 2
The anwser is 5 2/3 hope it helped :)
A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
ω = 40 revolutions per minute. 1 minute = (1/60) hour.
= 40*2π radians / (1/60) hour = 4800π radians per hour π = 3.14
= 4800*3.14 = 15072 radians / hour
but radius, r = 30 inches, 63360 inches = 1 mile, 30 inches = (30/63360) mile
Linear velocity, v = ωr
v = 15072 radians / hour * (30/63360) mile
v ≈ 7.136 miles / hour
b) Linear velocity, v = ωr
v = 8.9 radians/second * 20 cm
v = 178 cm/s
