Answer:
- decay
- decay
- growth
Step-by-step explanation:
If the base of a positive exponential is greater than 1, the function is a growth function. If it is less than 1, the function decays.
Remember that a^-1 = 1/a, so a negative exponential can be transformed to a positive one.
__
1. y = 2(11/5)^-x = 2(5/11)^x . . . . 5/11 < 1, so decay
2. y = e^(-2x) = (1/e^2)^x . . . . 1/e^2 < 1, so decay
3. y = 1/4e^x . . . . e > 1, so growth
_____
e ≈ 2.71828 . . . an irrational number
Answer:
The lower limit is 75.04
The upper limit is 78.96
Step-by-step explanation:
From the question we are told that
The sample size is 
The sample mean is 
The standard deviation is 
Given that the confidence level is 95% then the level of significance is mathematically represented as
The critical value for 
obtained from the normal distribution table is
Generally the margin of error is mathematically represented as
=> 
=> 
The 95% confidence interval is mathematically represented as
=> 
=> 
Answer:
I think it will be 2/1
Step-by-step explanation:
Its positive I know that, but since the points go right two and up one that should be the slope if i'm not mistaken.
The slope of these points is 4/3
