-1/3
Step-by-step explanation:
The common difference is how much it goes up by with each new number, so you can see that each time it goes down by 1/3. This means that the common difference is -1/3.
Answer:
a = 108° and b = 144°
Step-by-step explanation:
The opposite angles of a rhombus are the same and the sum of all the angles of the rhombus is 360°.
So, from the given diagram of the rhombus we can write
2b + 2× 36 = 360
⇒ 2b = 360 - 72 = 288
⇒ b = 144° (Answer)
Again, the each angles of a pentagon is given to be a.
Hence, we can write 3a + 36 = 360
⇒ 3a = 324
⇒ a = 108° (Answer)
Answer: 
We are 99% sure that the true population mean falls in interval .
Step-by-step explanation:
Let 
be the sample proportion.
As per given , we have
Standard error = 0.024
Critical value for 99% confidence interval :
Confidence interval is given by :-
Then, the 99% confidence interval will be :-
Hence, a 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter :
Interpretation : We are 99% sure that the true population mean falls in interval .
