A cosmetics company conducted a survey to anticipate potential sales of various new products from its upcoming catalog. The survey was conducted by randomly selecting women from two different age groups with 400 women in each group. The women selected the product that they would most likely purchase when it became available. The results obtained are given in the table shown below.
Products Ages 21 - 30 Ages 31 - 40
Product 1 163 152
Product 2 84 89
Product 3 104 109
Product 4 49 50
Which of the following statements about the data above is true?
A.
The estimates for both age groups show an equal number of women would have voted for Product 3.
Answer: The answer is f(x) = -7x + 7.
Step-by-step explanation: We are give a relation as follows :
From here, we need to find the expression for f(x).
Here, we will be using the following properties of exponents :
We have
Thus, the required expression is f(x) = -7x + 7.
Answer:
$30,000 and $55,000
Step-by-step explanation:
If 4.5% loan is x, and the 6% loan is y, then:
x + y = 85000
0.045x + 0.06y = 4650
Solve the system of equations with substitution or elimination. Using substitution:
0.045x + 0.06(85000 − x) = 4650
0.045x + 5100 − 0.06x = 4650
450 = 0.015x
x = 30000
y = 55000
If it looks like this
y = 161*(0.725)^t then it's a decay. Reason: the base is under 1. Try a couple of values for t say 0,1,2
y = 161 * (0.725)^0
y = 161
y = 161 * (0.725)^1
y = 161 * 0.725
y = 116.7
y = 161 * (0.725)^2
y = 161 * (0.5256
y = 84.63
You can see that the function is steadily getting smaller. Remember if the base is under 1 and more than 0 the function decays. If it is greater than 1 then the function grows.
Just to make sure we understand what I'm saying
0 < base < 1
y = a ( base)^power.
