678 to the nearest hundred the answer is 700
Answer: ( -∞ , - 21 )
Step-by-step explanation:
Let the number be x , so from the question , we have
5(x+27) ≥ 6 ( x + 26 )
expanding , we have
5x + 135 ≥ 6x + 156
5x - 6x ≥ 156 - 135
- x ≥ 21
Therefore :
x ≤ - 21
So , the numbers less or equal to -21 are -21 ,-22 , -23 ...
so the solution set is ( - ∞ , 21 )
The 99% confidence interval for the population proportion is given by

Given that 52% = 0.52 is the standard proportion and the standard error is 2.4% = 0.024.
Therefore, the <span>99% confidence interval for the fraction of u.s. adult twitter users who get some news on twitter is given by

</span>Therefore, the <span>99% confidence interval for the fraction of u.s. adult twitter users who get some news on twitter is 45.82% and 58.18%.
The interpretation of the confidence interval</span> is as follows: "We are 99% confident that the fraction of U.S. adult twiter users who get some news on twitter is between 45.82% and 58.18%.
