According to the empirical (68-95-99.7) rule, if a random variable has a standard normal distribution, then approximately 95% of all values fall between ‑scores of –2 and 2. Use the standard normal table to determine the precise positive value of such that 95% of the area under the standard normal density curve is between − and .

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

y -5 = (-1/4)(x + 8)

step-by-step explanation:

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
