Answer: 1.960
Step-by-step explanation:
The value of z we use to calculate a confidence interval with a (
) confidence level is a two-tailed test value i.e. represented by :-
Given : The level of confidence: 
Then, significance level : 
With the help of standard normal distribution table for z , we have
Hence, the value of z should be used to calculate a confidence interval with a 95% confidence level =1.960
9.2x10^-8
Move the decimal to the right 8 times. Since it is moved to the right, the exponent is negative.
cos(30)=x/8
Rewrite the equation as
x/8=cos(30)
Multiply both sides of the equation by
8
.
8
⋅
x/8=8⋅cos(30)
Simplify both sides of the equation.

Answer:
y > 0 best describes the range of the function f(x) = 2(3)x.
A function whose value is a constant raised to the power of the argument, especially the function where the constant is e.
