Answer:x=40
Step-by-step explanation: So since we know that AD is parallel to BC We know that M<c and M<a are congruent so we can use this equation to solve for x
2x-20= x+20
+20 +20
2x=x+40
-x -x
x=40
Answer: B. Population X will require a larger sample size
Step-by-step explanation:
- If a random variable say p has skewed distribution (whether right or left ) in a population then a bigger sample size is needed to make sure that the sampling distribution follows normal distribution.
Given : Two population distributions labeled X and Y.
Distribution X → highly skewed
Distribution Y → slightly skewed.
Since Distribution X more skewed so , we will need a larger sample size of population X as compared to Y.
Hence, the correct answer is B. Population X will require a larger sample size
Yes, because 9/11 is divided as a repeating number. A rational number repeats, so the answer is yes!!
