T=90-Z
Because 9 solved correctly*10 points per question answered correctly=90 and each incorrect question is a point lost
(y2-y1)/(x2-x1)
=(5-3)/(3-2)
=2/1
=2
so the slope is 2
hope this helps !
Answer:
0.66
Step-by-step explanation:
24.95 x 25%=6.23
24.94 - 6.23 = 18.72
25.80 x 30% = 7.74
25.80 - 7.74 = 18.06
18.72 -18 .06 = 0.66
