Answer:
the 3rd one
Step-by-step explanation:
Step-by-step explanation:
To find a percent, you need to put the numbers into a fraction first. Since the total number of beads is there, that is the denominator (number on the bottom of the fraction). The purple bead number will go on the top. This makes the fraction 8/12. When you divide 12 by 8, you get the decimal 0.66666667. You move the decimal two places over and get ~66%. This makes your answer B. Hope this helps! :)
Answer:
Step-by-step explanation:
The ratio of the same side interior angles of two parallel lines is 33:3
If two parallel lines are cut by a transversal
Sum of the same side interior angles = 180 degrees.
Therefore, the two same-side interior angles are:
We can then say that the measure of all eight angles formed by the parallel lines and transversal starting from the upper left in a clockwise rotation is:
Using the t-distribution, the 95% confidence interval for the average number of hours of sleep for working college students is between 6.03 and 6.97 hours.
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:
In which:
- is the sample mean.
- s is the standard deviation for the sample.
For this problem, the parameters are given as follows:
Hence the bounds of the interval are:
The 95% confidence interval for the average number of hours of sleep for working college students is between 6.03 and 6.97 hours.
