Answer:
This variable that is impacted by manipulating the independent variable is known as dependent variable
Step-by-step explanation:
One of the methods to test a hypothesis is the use of independent variable. The independent variable is manipulated to know if the change will be effective or not.
The variable which will be impacted by the independent variable is called dependent variable. The researcher manipulated the values for independent variable to check if the dependent variable changes or not ..
This is an exponential decay problem.
Using the equation Y = a *(1-rate)^time
where Y is the future value given as 12,000 and a is the starting value given as 13,000.
The rate is also given as 5%.
The equation becomes:
12,000 = 13,000(1-0.05)^x
12,000 = 13,000(0.95)^x
Divide each side by 13000:
12000/13000 = 0.95^x/13000
12/13 = 0.95^x
Use the natural log function:
x = ln(12/13) / ln(0.95)
x = 1.56 years. ( this will equal 12,000
Round to 2 years it will be less than 12000.
Answer:
3 • (2x - 7) - (x + 4) = 0
then do 3.1 Pull out like factors :
5x - 25 = 5 • (x - 5)
5 • (x - 5) = 0
4.2 Solve : x-5 = 0
Add 5 to both sides of the equation :
x = 5
Step-by-step explanation:
Okay. To find the distance apart from each other, subtract 15.3 and 7.5. When you do that, you should get 7.8. -7.5 and -15.3 are 7.8 units away on a number line.
