Answer:
B
Step-by-step explanation:
At t=0, the value is ...
C(0) = 50,000·(0.9^0) -2000 = 48,000
At t=20, the value is ...
C(20) = 50,000(0.9^20) -2000 = 6079 -2000 = 4079
The only graph that matches these end points is B.
Answer:
0.278
Step-by-step explanation:
Given that Nuri joins a game for a car. The rule is that Nuri pick one key from box either A, B, or C. A box has two keys but only one can be used. B box has three keys but only one can be used. C box has two keys but none of them can be used.
Each box is equally likely to be selected.
In other words

If A is selected then probability of winning is using the correct key out of two keys i.e. 0.5
If B is selected then probability of winning is using the correct key out of three keys i.e. 0.333
If c is selected then probability of winning is using the correct key out of two keys i.e. 0.00
So the probability that Nuri can win the car
= 
$125-$81.25 =$43.75 so that is how much was saved. Now figure what percentage $43.75 is of $125. so $43.75÷$125=.35 and changing to % the discount is 35%
Answer:
The answer is A
Step-by-step explanation:
Answer:
x=1.818minutes
Step-by-step explanation:
3/60 miles per minute for walk
8/60 miles per minute for run
0.05x + 0.1333y=1
x+y=10
x=y-10
0.05(y-10) + 0.133333y = 1
0.05y-0.5+0.133333y=1
0.18333y=1.5
y=8.18minutes
x=10-8.18
x=1.818minutes
