If two parallel lines are cut by a transversal,
then alternate interior angles are congruent.
Since one alternate interior angle measures 60 degrees,
the other alternate interior angle must also measure 60 degrees.
The rate of travel, or speed, is
200 miles
--------------- = 40 mph
5 hours
Recall that distance = rate times time, so that rate = distance / time.
The answer is 5.196152423
Since - x^2=27
X=square root of 27
=5.196152423
39 miles on 3 gallons = 39 / 3 =
13 miles per gallon
Traveling 26 miles requires (26 / 13) equals
2 gallons of gas.
Answer:
Using a 95% confidence level, the lower end point of a two-tailed interval that would be used to predict the range of values that this 17th sampled unit would be in with respect to seconds soaking a component part in solution is of 29.137 seconds.
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 = 16 - 1 = 15
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 15 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.1315
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 33.4 - 4.263 = 29.137 seconds.
Using a 95% confidence level, the lower end point of a two-tailed interval that would be used to predict the range of values that this 17th sampled unit would be in with respect to seconds soaking a component part in solution is of 29.137 seconds.
