Therefor you use the compound interest formula:Kerry has a credit card. She is charge 0.05% compound interest per day on outstanding balances.
How much nterest is Kerry charged on an amount of $250, which is outstanding on her credit card for 30 days?
That would be correct if you were finding the mean score, however the line of regression requires the median score.steph123 said:for q 28 (c) (i) i put the corresponding point C as (58.3, 170)
because...isnt 55+50+70/3= 58.3??
Group 1 - 50, 60, 70 - median of 60 - point was 155,60steph123 said:yeh....except the other A and B points seemed to use the mean...i.e- point A..if it was the median wouldnt they use point 70,155? but instead they used (60,155)
