Step-by-step explanation:
P(t) = 12,000 (2)^(-t/15)
9,000 = 12,000 (2)^(-t/15)
0.75 = 2^(-t/15)
ln(0.75) = ln(2^(-t/15))
ln(0.75) = (-t/15) ln(2)
-15 ln(0.75) / ln(2) = t
t = 6.23
The median for data A is greater.
the mean for data A is greater.
The equation representing the given relationship is
y = 0.50x + 15
Given, The cost for renting a car a day is $0.50 per mile, plus a $15 flat fee.
we have to find an equation to represent the given relationship.
Let the number of miles driven be, x
and the total cost be, y
total cost = cost per mile × miles driven + flat fee
Total cost = 0.50 × miles driven + 15
y = 0.50x + 15
Hence, the equation representing the given relationship is
y = 0.50x + 15
