Answer:
f(t) = 66·0.995^t
Step-by-step explanation:
You can try t=0 and t=1 in each of the formulas to see which one gives values of 66 and 0.5% less than 66, or 65.67.
The first function has an initial value of 0.5, so is not correct.
The second function gives f(1) = 99, so is not correct.
The third function gives f(1) = 65.67, so is correct.
The fourth function gives f(1) = 66.33, so is not correct.
_____
You can realize that the multiplier will be 0.5% less than 100%, so will be 99.5% = 0.995. This number shows up only in the third selection.
If 8 apples cost $ 4, then (4/8) = 1/2 (or 0.50)....so each apple is 0.50 (or 50 cents)
so if u want 9 apples, u will have to pay : 9 * 0.50 = $ 4.50 <=
The mode is defined as the number that appears most within a given sequence.
The median is the middle number of a given sequence listed from least to greatest.
Let's look for the mode.
We have:
4
5
7
8
9, 9
10.
9 appears the most, so the mode is 9.
Let's find the median now.
4, 5, 7, 8, 9, 9, 10.
Cross out the smallest number with the largest number until we can no longer do so.
5, 7, 8, 9, 9.
7, 8, 9.
8.
Your median is 8.
Your mode is 9.
I hope this helps!
