Answer:
2 (C)
Step-by-step explanation:
The "bisector" of the two sides is always equal to 1/2 of the base so...
2(3x-1) = 2x+6
Then, we simply btoh sides...
6x-2 = 2x+6
Then, we bring all the variables to one side and the numbers to the other..
4x = 8
Finally, we simplify to get our answer...
x=2 (C)

The interval of true average price of a regular room with a king size bed in the resort community with 99% confidence is ( 14.74, 48.89 ).
<h3>What is the confidence interval of an average?</h3>
One method of determining the actual population mean is by using a confidence interval for the mean. A confidence interval provides a lower estimate and an upper estimate rather than just the mean.
A confidence interval expresses the degree of uncertainty surrounding a given statistic. A margin of error is frequently used with confidence intervals. It reveals the degree to which you may be certain that the findings of a poll or survey correspond to what you would anticipate discovering if it were possible to poll the complete population. Levels of confidence are inextricably linked to confidence intervals.
x = mean;
99% confidence interval for μ is
(x - t * S) /√n < μ <( x + t * S) /√n;
(135 - 2.898 * 25 )/√18 < μ < (135 + 2.898 * 25)/√18;
14.74< μ< 48.89;
99% CI is ( 14.74, 48.89 ) ;
critical value at 0.01 significance level with 17 df = 2.898
