You flip a coin 8 times and record the results using 0 for heads and 1 for tails. you find the variance. is investigating this sample variance the same as investigating the sampling distribution of the variance?

1/3(x-10)=-4 solve for x with steps

Can someone me with this? i’m not sure what to put for my equations.

Jenny invests $2,000 at an interest rate of 5%. the amount of money, me, in jenny's account after tyears can be represented using the equation ma-2000(1.05). if jenny would have invested the same amount of money at the same interest rate four years ago, the equation representing the amount of money mo. in her account would be represented using the equation! mg = 2000(105)*** which of the following is equivalent to mp? 2000(105) om- 1.05 2000(1.05) mo 1059 mp-2000(1.05) (105) mp - 2000(1.05) + (1.05)
