$3.00 x .05 = 15 cents
$3.00+ .15= $3.15
3.15 final answer
the three numbers are 49,56 and 63.
First, we get the z-score using formula:
z =( X - μ ) / σ
From the problem, we substitute the given values:
z = (9 - 7.8) / 1.7
z = 0.71
From the z-table (one-tailed), for a z-score of 0.7059, the proportion of numbers that are greater than 9 is 0.76.
