You have been given authorization to study a flame-resistant material. there are 8 key factors, (a, b,c, d,e, f,g, h) 1. how many samples at a minimum would you need to request to perform a full fractional experiment of any use? 2. you have been authorized only 100 samples at maximum. what are the feasible balanced fractional experiments you could run? 3. for each of the experiments you listed in the last part, what are the engineering trade-offs in the feasible ones? 4. pick your choice of experiment and state issues with that experiment you would need to keep in consideration during the analysis phase. 5. assume de and bc are significant and critical two way interactions, use the frf2 package to determine generators for your choice above to address these.

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
