Answer: 2 1/4 hours
Step-by-step explanation:
If Rafael practices 3/4 of an hour each day for three days he will have had 3/4 of an hour practice after day 1, 1 1/2 hours of practice after day 2 and then 2 1/4 hours of practice after day 3.
3 x 3/4 = 9/4
9/4= 2 1/4
Answer:
1/6 is the probability of it being a green plastic marble.
Step-by-step explanation:
Note that there are 18 marbles in all (12 + 6 = 18).
Half of the green marbles (6) are made of plastic: 6/2 = 3
From the information above, we see that 3 green marbles are made of plastic. There are 18 marbles in all.
Divide, and simiplify.
(3/18)/(3/3) = 1/6
1/6 is the probability of it being a green plastic marble.

Answer:
C 10% Condition.
Step-by-step explanation:
Let's Look at them one by one.
A: Large Enough sample condition.
this is met because 600 students is a good number to carry out a surwey.
B: Randomization, 600 incoming freshman are definitely random.
C: we are left with C so the answer is C.
Using an exponential function, it is found that the value of the car after 5 years will be of $8,527.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
For this problem, the initial cost and the decay rate are given as follows:
A(0) = 23000, r = 0.18.
Hence the value of the boat after t years is given as follows:
The value after 5 years will be of:
The value of the car after 5 years will be of $8,527.
