Jarryd received a mark of \( 75 \% \) on both his Diagnostic Test and his Assignment 1 assessment items. (Have you done your Diagnostic Test yet? It's not too late. You are missing out on \( 5 \% \) of your available mark towards your final grade if you haven't). The Diagnostic test was weighted at \( 5 \% \) of the final mark and the Assignment 1 was worth \( 15 \% \) of the final grade. Hence Jarryd has completed \( 20 \% \) of the assessment weighting for the semester. His mark out of 20 at this stage is this stage 15 . There are various ways to calculate that mark and one of the options below is incorrect. Which option below is incorrect? So Jarryd has \( 15 \% \) out of \( 20 \% \) towards his final mark. (A) \( 5 \times 0.75)+(15 \times 0.75)=15 \) So Jarryd has \( 15 \% \) out of \( 20 \% \) towards his final mark. (C) \( \frac{(5 \times 75)+(15 \times 75)}{100}=15 \) So Jarryd has \( 15 \% \) out of \( 20 \% \) towards his final mark. (D) \( 0.5 \times 75)+(0.15 \times 75)=15 \)
