465 / 3 = 155
so -153 + -155 + -157 = -465
Answer:
Step-by-step explanation: Your supposed to move 1.5x to the other side of 2y. Then you have -1.5x on the right side. Divide all terms by 2 and you’ll get your equation in y=mx+b format. Hope this helps
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
The answer for this problem is 2 since it is not specified whether it is adjacent to the right or adjacent to the left.
If it is adjacent to the right, the answer is:
p (k) = 2 * p(1) + 2 * k
If the is adjacent to the left, the answer is:
P (k) = 2 *p(1) +2 * (k-2)
