Stop marking at the second calculation error. • Assuming answers/values in order to solve a problem is NOT acceptable. LET WEL: • As 'n kandidaat 'n vraag TWEE KEER beantwoord, sien slegs die EERSTE poging na. • As 'n kandidaat 'n antwoord van 'n vraag doodtrek en nie oordoen nie, sien die doodgetrekte poging na. • Volgehoue akkuraatheid word in ALLE aspekte van die Nasienriglyne toegepas. Hou op nasien by die tweede berekeningsfout. • Aanvaar van antwoorde/waardes om 'n probleem op te los, word NIE toegelaat nie. GEOMETRY • MEETKUNDE A mark for a correct statement (A statement mark is independent of a reason) S 'n Punt vir 'n korrekte bewering ('n Punt vir 'n bewering is onafhanklik van die rede) A mark for the correct reason (A reason mark may only be awarded if the statement is correct) R 'n Punt vir 'n korrekte rede ('n Punt word slegs vir die rede toegeken as die bewering korrek is) Award a mark if statement AND reason are both correct S/R Ken 'n punt toe as die bewering EN rede beide korrek is Copyright reserved/Kopiereg voorbehou Please turn over/Blaai om asseblief ### Page 3 Mathematics P2/Wiskunde V2 3 DBE/November 2024 NSC/NSS – Marking Guidelines/Nasienriglyne QUESTION/VRAAG 1 Weight 34 32 40 27 33 28 27 55 39 44 30 57 28 32 31 (in kg) (x) Number of push- ups per minute 26 21 6 20 16 26 23 7 18 14 17 8 28 25 20 (y) Scatter plot 30 25 Push-ups per minute 20 15 10 5 0 0 10 20 30 40 50 60 Weight (in kg) 1.1 a = 39,456001… ✓ a = 39,46 b = – 0,590018… ✓ b = – 0,59 yˆ = 39 ,46 − 0,59 x CORRECT ANSWER ONLY: FULL MARKS ✓ equation (3) 1.2 r = – 0,8 ✓(A) – 0,8 (1) 1.3 y = 39,46 – 0,59(29) ✓ substitution y = 22,35 ✓ answer (2) OR/OF y = 22,35 (calculator) ✓✓ answer (2) 1.4 y = 18 ,33 ✓(A) 18,33 (1) 1.5 The increase in the number of push-ups will have no influence. ✓ no influence OR The standard deviation stays the same. standard deviation remains the same geen verandering / bly dieselfde (1) 1.6 6 is furthest y-value below the least squares regression line. ✓ 6 An increase of 10 push-ups will get the team member to ✓ difference is 10 (40 ; 16), the minimum number of push-ups for a player weighing 40kg.
