Hi!
Samuel bought the mixer for $54,205. The value of this (the prive) decreases every year at a costant rate (so, for example, it may decrease of $100 every year).
we are solving for t and we should keep in mind that we multiply the price for the function (1 - rate/100)^time
in f(t) you put the value of year 1 for example

Solving for r will bring us to the solution, and we can substitute 1 to t since we are calculating how much it decreases after ONE year.
We would divide for 54205 to cancel out that 54205 multiplicating the parenthesis.
Also, the x is given by the formula (vale2-value1)/value1 to see how much the price changes from year 1 to year 2
We will get

Again, it would be:
f(t) = 54205(0.13)^1
Answer:
c is the answer i believe
Step-by-step explanation:
Answer:
Option B) data from the sample is used to estimate the population parameter
Step-by-step explanation:
Point estimation:
- Its is the process of getting a point estimate from a sample that describes a population parameter in the best way.
- We calculate the unknown population parameter with the help of a sample drawn from the population.
- It is similar to interval estimation.
- In interval estimation we obtain an interval in which the population parameter may lie but in point estimation we obtain a single value which is the best approximation of population parameter.
Thus, the correct answer is
Option B) data from the sample is used to estimate the population parameter

Area of a triangle:

In our case:
b=4
h=2
Plug in what we know:

Find the matching solution:
A.) it is 1/2 the area of a rectangle of length 4 units and width 2 units
X B.) it is twice the area of a rectangle of length 4 units and width two units
X C.) it is 1/2 the area of a square of side length 4 units
X D.) it is twice the area of a square of side length 4 units
Answer:
c=60m+35
Step-by-step explanation:
c is the cost so it should be equal to and 60 a month so 60m and +35
