Tanya [424]

Answer:

Expanded: (y-3)(y-3)(y-3)

Simplified: $y^{3}-9y^{2}+27y-27$

Step-by-step explanation:

Expanded: (y-3)(y-3)(y-3)

Simplified:

$y^{2} -3y-3y+9(y-3)\\y^{2} -6y+9(y-3)$

$y^{3} -3y^{2}-6y^{2} +18y+9y-27$

$y^{3}-9y^{2} +27y-27$

Sample standard deviation

Mean of data = 84.4

Calculate deviations from the mean = 23.4, 17.8, 3.4, 1.4, -2.6, -3.6, -4.6, -5.6, -13.6 and -15.6

Squaring these deviations; we get 547.56, 316.84, 11.56, 1.96, 6.76, 12.96, 21.15, 31.36, 184.96, 243.36

Adding these we get 1378.47

As its a sample Std Dev we divide by 10 - 1 = 9. For the popklation Std Dev we divide by the number of scores (10).

Std Deviation for sample = sqrt ( 1378.47 / 9) = 12.4 to nearest tenth (answer)

Population Std Dev = sqrt (1378.47 / 10) = 11.7 answer

Theres a lot of arithmetic there so hope i haven't slipped up anywhere!
