The function f(x) = x + is used to complete this table. a 2-column table with 4 rows. the first column is labeled x with entries negative 1, 0, 1, 2. the second column is labeled f of x with entries 1, three-halves, 2, five-halves. which statements are true of the given function? check all that apply. fstartfraction negative 1 over 2 endfraction = –2 f(0) = three-halves f(1) = –1 f(2) = 1 f(4) = seven-halves

X2 + y 2 = 36 x + y = 6 solve the system of equations.

3.17 scores on stats final. below are final exam scores of 20 introductory statistics students. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 57, 66, 69, 71, 72, 73, 74, 77, 78, 78, 79, 79, 81, 81, 82, 83, 83, 88, 89, 94 (a) the mean score is 77.7 points. with a standard deviation of 8.44 points. use this information to determine if the scores approximately follow the 68-95-99.7% rule. (b) do these data appear to follow a normal distribution? explain your reasoning using the graphs provided below.
