-1/2 * 16 = -8
или 16/(-2) = -8
Quadrant 3 will have a negative x and a negative y........so ur answers are :
A and C
Answer:
16.7% (rounded)
Step-by-step explanation:
Step 1. Make a proportion, which is 2/12 times x%/100
Step 2. Cross multiply = 2*100/12
Step 3. Solve = 16.(6) or, 16.7% rounded!
68% will be 1 standrd deviation either side of the mean so a reasonable estimate will be (25*0.68) / 2 = 8.5
180 - (30+35)
= 180 - 65
= 115
M = 115 (vertical angles)
