1.22 / 1,22
because:
100% of 100 is 100. You multiplied it by one.
110% of 100 is 110. You multiplied it by 1.1 / 1,1
So if you want to multiply by a percentage between 100 and 200 you have to multiply by a number between 1 and 2.
Answer:
Confidence interval: (21.9, 32.9).
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 26 - 1 = 25
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 25 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.485
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 27.4 - 5.5 = 21.9 hours
The upper end of the interval is the sample mean added to M. So it is 27.4 + 5.5 = 32.9 hours
Confidence interval: (21.9, 32.9).
Answer:
Step-by-step explanation:
The answer is 24° because all three the three angel of the triangle is 180° and u subtract 132 by 180 left with the other two small angel's sum which is 48. rhan u divided by two u get one of the angel which is 24°.
im pretty bad at explaining, hopefully it helps!
