Answer:
We have been given confidence interval 95%, mean 20 , data set 30 and standard deviation 3.
We will use the formula: 
Here,
Z-score value at 95% confidence interval is 1.96
On substituting the values in the formula to plug the values:
Now, we have a formula for marginal error:
Marginal error means your answer will be within that percentage only.
Say you have 3% marginal means your value will be within 3% real population 95% of the time.
Answer:
what is difficult about this problem? do you not have a calculator? what part is tough?
Step-by-step explanation:
A. If p = a number is negative and q = the additive inverse is positive, the original statement is p → q.
B. If p = a number is negative and q = the additive inverse is positive, the inverse of the original statement is ~p → ~q.
D. If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q.
Answer: 9
Step-by-step explanation:
Evaluate=
(256 x 3^-5 x 6)^-2 x (3^2/2^3)^4 x 2^28
(256 x 1/243 x 6)^-2 x (3^2/2^3)^4 x 2^28
(256 x 1/243 x 1)^-2 x (3^2/2^3)^4 x 2^28
Multiply=
(256/243)^-2 x (3^2/2^3)^4 x 2^28
Evaluate=
59049/65536 (3^2/2^3)^4 x 2^28
59049/65536 (1/9/2^3)^4 x 2^28
59049/65536 (1/9/8)^4 x 2^28
Divide=
59049/65536 (1/72)^4 x 2^28
Evaluate=
59049/65536 x 1/26873856 x 2^28
59049/65536 x 1/26873856 x 268435456
Multiply=
9
