Sami designs a number generator that produces the integers 0 to 4. She then runs the generator 632 times. The results are shown in the table below. Use The table below to answer each of the questions below. If Karen runs the generator a total of 5,000 times, what is the expected number of times the integer 2 is produced?

Solve the equation - 2(m -30) = -6m a-15 b-13 c-8 d8

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.

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
