Answer:
Around 2397 Americans must be surveyed to get a margin of error of 2%.
Step-by-step explanation:
We are given the following in the question:
Proportion of US residents who thinks marijuana should be made legal = 48%
We have to construct a 95% confidence interval.
Margin of error = 2% = 0.02
Formula for margin of error =
Putting values, we get,
Thus, around 2397 Americans must be surveyed to get a margin of error of 2%.
A rectangular prism has 6 surface.
The function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.
<h3>Exponential equation</h3>
The inverse of exponential equation is logarithmic equation. The standard exponential equation is expressed as;
y = ab^x
where
a is the initial value
b determine the growth rate or decay.
If the value if b < 1, then it is a decay otherwise it is growth.
Given the function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.
