30 seconds every 15 minutes.
The total time passed was 8 hours and 16 minutes. 16 minutes late meant that the trip normally takes 8 hours. over 8 hours 16 minutes were lost. 16min divided by 8 hours is 2 minutes per hour. 2 minutes is 120 seconds (2*60). there are four 15 minute intervals in an hour so 120/4= 30 seconds per every 15 minutes.
To solve this problem, we make use of the z statistic.
The formula for the confidence interval can be calculated using the formula:
Confidence Interval = p ± MOE
where,
p is the portion of girls = 278 / 556 = 0.5
MOE is the margin of error
We calculate the margin of error using the formula:
MOE = z * sqrt[p (1 – p) / n]
From the standard distribution tables, the value of z at 99% confidence is:
z = 2.58
Therefore the MOE is:
MOE = 2.58 * sqrt[0.5 (0.5) / 556]
MOE = 0.055
Therefore the confidence interval is:
Confidence Interval = 0.5 ± 0.055
Confidence Interval = 0.445, 0.555
0.445<p<0.555
3x+6=-5-2x+6
3x=-5-2x
3x+2x=-5
5x=-5
x=-1
<span>This question requires only one calculation to determine the answer. A full turn is 360 degrees. Therefore, to find the degree measure of two thirds of a full turn, we multiply 360 degrees by 2/3. This gives us 240 degrees.</span>
