Anita works at a bike shop. the shop receives a shipment of new tires that are supposed to be less likely to get flats than the shop's current tires. anita puts the current tires on a random sample of 8 bikes and puts the new tires on a random sample of 8 bikes. she collects data on the number of flats for each bike over a one-year period. current tires: 4, 5, 7, 2, 3, 9, 7, 5 new tires: 1, 3, 3, 3, 1, 2, 1, 2 the means are 5.25 and 2 respectively, for a difference of 3.25. anita wants to know if this is significant or if it could be caused by chance. to find out, she re-randomizes the results 15 times and finds the differences of the means. the dot plot shows the data. what is the best conclusion for anita to make based on the data? the difference of 3.25 is significant because the re-randomizations show that it is within the range of what could happen by chance. the difference of 3.25 is not significant because the re-randomizations show that it is within the range of what could happen by chance. the difference of 3.25 is not significant because the re-randomizations show that it is outside the range of what could happen by chance. the difference of 3.25 is significant because the re-randomizations show that it is outside the range of what could happen by chance.

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

steve should create a type of business report called a business plan. the correct option among the options that are already given in the question is the last or the fourth option. this business report created by steve will actually influence the investors about investing their money in steve's business. this business report will have all the details about the business, the amount of investment required and the amount of expected profit.

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!
