I need help on 34 and 36
aleksley [76]
34. 65 = 3/4c - 7....add 7 to both sides
      65 + 7 = 3/4c...simplify
       72 = 3/4c...multiply both sides by 4/3, eliminating the 3/4 on the left
       72 * 4/3 = c
       288/3 = c
       96 = c

36. -5/2 = 3/4z + 1/2 ...subtract 1/2 from both sides
      -5/2 - 1/2 = 3/4z .... simplify
       -6/2 = 3/4z ....reduce
       -3 = 3/4z....multiply by 4/3. eliminating the 3/4 on the left
      -3 * 4/3 = z
       -12/3 = z
       -4 = z

Please answer this question...
irina1246 [14]

Answer:  I believe the standard deviation will remain the same, 6, choice A.

Step-by-step explanation:  Standard deviation is calkculated based on the difference of each point from the mean.  If 10 were added to each score, the mean would also increase by 10.  That would mean that the difference between the mean and each score would be exactly the same, leading to an identical standard deviation.  Sounds crazy, but that's what numbers do for a living.
