Step-by-step explanation:
Opposite angles are equal, so we know that C=2x and D=5x+5 as well.
The sum of the interior angles of any quadrilateral is 360, so we have
So, the measures of the angles are

Answer:
Step-by-step explanation:
The average weight of a package of rolled oats is supposed to be at least 18 ounces
Null hypothesis: u >= 18
Alternative: u < 18
Using the t-test formula, we have
t = x-u/ (sd/√n)
Where x is 17.78, u = 18, sd = 0.41 and n = 18
t = 17.78-18 / (0.41/√18)
t = -0.22 / (0.41/4.2426)
t = -0.22/ 0.0966
t = -2.277
Since, this is a left tailed test, at a significance level of 0.05, the p value is 0.01139. Since the p value is less than 0.05, we will reject the null hypothesis and conclusion that the true mean smaller than the actual specification.
Answer: Your answer is: C. The range of the speeds after the course is smaller than the range of the speeds before the course.
