Answer:
28/15 or 1 13/15
Step-by-step explanation:
All triangles inner angles addition equals to 180°
So if you’re finding the x° then minus the other angles from 180°
23°+129°+x=180°
x=180°-129°-23°
x=28°
I hope this helped :)

Answer: There is enough evidence to support the claim that the population mean of the students at this college is less than the recommended number of 8.4 hours.
Step-by-step explanation:We are given the following in the question:
Population mean, μ = 8.4 hours
Sample mean, = 7.72 hours
Sample size, n = 237
Alpha, α = 0.01
Sample standard deviation, s = 1.02 hours
First, we design the null and the alternate hypothesis
We use one-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since, the calculated test statistic is less than the critical value, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Conclusion:
Thus, there is enough evidence to support the claim that the population mean of the students at this college is less than the recommended number of 8.4 hour
