Answer:
.
Step-by-step explanation:
We have been given that 4 days I have 140 copies of a book, 9 days I only have 50 left. We are asked to write an equation , where c is number of copies still on hand and t days being available.
We have two points on line (4,140) and (9,50). Now, we will use these points to find slope as:
Now, we will use point-slope form of equation and substitute
and coordinates of point (9,50) as:
Therefore, our required equation would be .
Answer:
f(2)=5
f(5)=33
Step-by-step explanation:
The given formula, that recursively defines the sequence is
When n=1, we obtain;
When n=2, we get:
When n=3,
When n=4
When n=5,
Answer:
(a) 51%
(b) 41%
Step-by-step explanation:
We can simplify this problem down by realizing that the amount of girls over 200 will get us our percentage as a decimal.
Looking at this table, we can see that girls were asked. So,
, and
.
We can also see that people preferred video games, so
, and
.
Hope this helped!
