Kyla Lynch · Answer 1

(1) average = (600 + 300 + 500 + 900) / 4 = 2300/4 = 575

(2) 600 - 575 = 175

300 - 575 = - 275

500 - 575 = - 75

900 - 575 = 325

(3) 175^2 = 30625

-275^2 = 75625

-75^2 = 5625

325^2 = 105625

(4) (30625 + 75625 + 5625 + 105625) / 4 =

217500 / 4 = 54375

(5) sqrt 54375 = 233.18 rounds to 233.2
