**Step-by-step explanation:**

i) Capacity(Volume) = length x breadth x depth

= 3.2 x 2.9 x 1.5

= 13.92 m³

In litres, 13.92 x 1000 = 139,20 litres

ii) Capacity(Volume) = length x breadth x depth

= 2.5 x 1.6 x 1.3

= 5.2 m³

In litres, 5.2 x 1000 = 5200 litres

iii) Capacity(Volume) = length x breadth x depth

= 7.3 x 3.6 x 1.4

= 36.792 m³

In litres, 36.792 x 1000 = 36,792 litres

**Answer:**

-69.19x + 38.2

**Step-by-step explanation:**

–9.2(8x – 4) + 0.7(2 + 6.3x)

-73.6x + 36.8 + 1.4 + 4.41x

-69.19x + 38.2

Hope this helps.

**Answer:**

20% of $68 is $13.60

**Step-by-step explanation:**

(20/100)x68

(20x68)/100

1360/100 = 13.6

**Answer:**

**1) **The expected value of the number of moving violations for which the individual was cited during the last 3 years is **1**

**2) **The expected amount of surcharges is $**250**

**Step-by-step explanation:**

Given that;

Y 0 1 2 3 4

p(y) 0.50 0.20 0.15 0.10 0.05

1)

Value of E(Y)

E(Y) = (0×0.50) + ( 1×0.20) + ( 2×0.15) + (3×0.10) + (4×0.05)

= 0 + 0.20 + 0.3 + 0.3 + 0.2

E(Y) = **1**

Therefore, The expected value of the number of moving violations for which the individual was cited during the last 3 years is **1**

b)

Suppose an individual with Y violations incurs a surcharge of $100Y² , the expected amount of the surcharge is given by,

E($100Y²) = 100E(Y)²

= 100∑Y²P(y)

= 100(0²×0.50) + ( 1²×0.20) + ( 2²×0.15) + (3²×0.10) + (4²×0.05)

= 100( 0 + 0.2 + 0.6 + 0.9 + 0.8 )

= 100(2.5)

= $**250**

Therefore; The expected amount of surcharges is $**250**

**Answer:**

why won't Ralph show 13/20 then?
