Answer:
45.2 is the constant of proportionality
Step-by-step explanation:
Direct proportionality says that:
then the equation is in the form of:
, where k is the constant of proportionality
As per the statement:
The distance, d, measured in miles, that Hye drove is
d = 45.2t, .....[1]
where,
t is the time in hours.
By definition of direct proportionality:
⇒
On comparing with [1] we have;
k = 45.2
Therefore, the constant of proportionality is, 45,2

Answer:
0.15 or 15%
Step-by-step explanation:
Since lengths are uniformly distributed, the probability that a class period runs between a two exact times is:
In this case, a = 47.0 and b = 52.0 minutes.
The probability that a given class period runs between 50.25 and 51.0 minutes is:
The probability is 0.15 or 15%.
