Answer:
The 95% confidence interval of the proportion of Americans who believe in the conspiracy is 
Step-by-step explanation:
From the question we are told that
The sample size is n =1057
The number that believe there was a conspiracy is k = 614
Generally the sample proportion is mathematically represented as
=> 
From the question we are told the confidence level is 95% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the margin of error is mathematically represented as
=> 
=> 
Generally 95% confidence interval is mathematically represented as
=> 
=>

Answer:
True
Step-by-step explanation:
Evaluate 18 x - 2 (3 x + 1) = 5 x - 16 where x = -2:
-2×18 - 2 (1 - 2×3) = -2×5 - 16
3 (-2) = -6:
-2×18 - 2 (-6 + 1) = -2×5 - 16
1 - 6 = -5:
-2×18 - 2-5 = -2×5 - 16
18 (-2) = -36:
-36 - 2 (-5) = -2×5 - 16
-2 (-5) = 10:
10 - 36 = -2×5 - 16
5 (-2) = -10:
10 - 36 = -10 - 16
10 - 36 = -26:
-26 = -10 - 16
-10 - 16 = -26:
-26 = -26
-26 is equal to -26:
Answer: True
Answer:
2
Step-by-step explanation:
First, simplify the top and bottom separately:
Then, just divide:
Let the first unknown number be
And the second unknown number be
We know that
÷
= 7
My number is a multiple of 7 and also multiple of This is because of 7 ×
=
-----------------------------------------------------------------------------------------------------------
The number I divided my number by can be any number but
ZERO
Because
÷ 0 is undefined
--------------------------------------------------------------------------------------------------------------
My number cannot be a number which we cannot divide by
SEVENBecause
÷
= 7, so
must be divisible by 7 to obtain
