Elevator ride: Engineers are designing a large elevator that will accommodate 46 people. The maximum weight the elevator can hold safely is 8970 pounds. According to the National Health Statistics Reports, the weights of adult U. S. men have mean 177 pounds and standard deviation 70 pounds, and the weights of adult U. S. women have mean 165 pounds and standard deviation 79 pounds. Use the TI-84 Plus calculator. Part 1 of 3 (a) If 46 people are on the elevator, and their total weight is 8970 pounds, what is their average weight

i dont know men

well the answer to that is xoxoxo

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!
