Answer:
z=14.73
p=0.000
for 99% confidence level the null hypothesis is rejected, thus majority of us adults would not bothered if the NSA collected personal records.
Step-by-step explanation:
: Half of US adults would not bothered if the NSA collect records of personal telephone calls
: Majority of the adults would not bothered if the NSA collect records of personal telephone calls
According to the sample, z-value can be found using the formula:
z=
where
- X is the adults, who would not be bothered in the survey (397)
- M is the mean of the distribution of null hypothesis (257)
- n is the sample size (514)
- p is the proportion of the sample, who said they would not bothered (
≈ 0.77)
Putting these numbers in the formula,
z=14.73 and corresponding p value is p≈0.000
Since p<0.01, for 99% confidence level we reject the null hypothesis, thus majority of us adults would not bothered if the NSA collected personal records.
Answer:
The fourth term is -102----------------------------------------------
Explanation:
The term after the nth term is generated by this rule
which means that we first
Step 1) multiply the nth term (
) by -4
Step 2) Add the result of step 1 to the value 2 to get the next term in the sequence
Let's follow those steps above to generate the first four terms
The first term is
. In short, the first term is 2
The second term is...
So the second term is -6
The third term is...
The third term is 26
Finally, the fourth term is...
The fourth term is -102.

Answers: choice C, choice D</h3>
Look at where we don't have repeating x values. This happens with function C and function D. All the x values are unique for each choice mentioned.
In choices A, B, and E, the value x = -3 repeats itself. So we don't have a function for either of these. A function is only possible if any input (x) leads to exactly one output (y).
Y= -1
it’s a horizontal line that is perpendicular to the y-axis
