To find 5 percent of a value, multiply the value by 0.05. In this instance, 0.05 x 1755 = 87.75 or $87.75
Check that coin again. There was no such thing as the United States in 1755, let alone a U.S. one dollar coin.
If: z -31 = 64 then the value of z is 95
A z-score of 0 means the value is the mean.
The U.S. did not exist in 1755. Please post a new question with more details that might help to ID your coin, including any wording on it and a description of the images.
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
0.97
10.2
The z-score, for a value z, is the probability that a Standard Normal random variable will have a value greater than z.
z-score of a value=(that value minus the mean)/(standard deviation)
z-score of a value=(that value minus the mean)/(standard deviation)
Z=²8² = 8x8 = 64the value of z = 8
