Tim Worker is doing his budget. He discovers that the average miscellaneous expense is $45.00 with a standard deviation of $16.00. What percent of his expenses in this category would he expect to fall between $38.60 and $57.80?
Enter the answers to the nearest tenth.
The z for $38.60 = ?
The percent of area associated with $38.60 = ?%.
The z for $57.80 = ?
The percent of area associated with $57.80 = ?%.
Adding the two together, the percent of his expenses between $38.60 and $57.80 is ?%.

If m∠abc = 70°, what is m∠abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°. using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°. using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
