<span>The formula to find the z score in a normally distributed set of data is: z = (x - ÎĽ) / Ď With ÎĽ being the mean, Ď being the standard deviation, and x being the score. Substituting these values into the formula gives us z = (800 - 500) / 100 = 3 The z-score of the 800 point score is 3.</span>

Luba_88 [7]

Answer:

Step-by-step explanation:

√48 = √(3*16) = 4√3

                   

                  √1

Determine whether the sequence converges or diverges. If it converges, give the limit: 72, 18. 9/2, 9/8, ...
kakasveta [241]
Answer: The sequence converges. The limit it converges to is 0.

-------------------------------------------------------------------------------------------

The sequence is a geometric sequence with a = 72 and r = 1/4. Because 0 < r < 1, this means that the sequence gets smaller and smaller. The terms get closer to 0. They don't actually get there but the limiting value is 0.
