Answer:
D.]
Step-by-step explanation:
We will find the standard deviation and variance:
Variance= E
-[![[E(x)]^{2}](https://tex.z-dn.net/?f=%5BE%28x%29%5D%5E%7B2%7D)
E[x] = 3.462
E[{x}^2]= 31.86
Var(x)= 31.86-(3.462)^2 = 28.4
Standard deviation = 
= 
= 5.833 = 6(aproximately)
Therefore, the chances of winning are equal in each lane.

Answer:
3. 273
4. 168
5. 189.25
Step-by-step explanation:
3. Triangle= .5 x 17 x 6 = 21
Rectangle= 18 x 14 = 252
252 + 21 = 273
4. Big rectangle (shaded)= 11 x18= 198
Small rectangle (right)= 5x4=20
Smaller rectangle (left)= 2x5=10
BR - (SR+SMR)
198-30=168
5. radius=5
Area of the circle= 25(pi)
Semi-circle= 39.25(not exact)
Rectangle= 10 x15=150
Rectangle + Semi-circle
150+39.25=189.25
B. Scale Drawing
