Write and solve an equation of ratios:

£1.40 2.5 kg

c 4.25 kg

Cross multiplying, we get:

(£1.40)(4.25 kg) = (2.5 kg*c), or

(£1.40)(4.25 kg)

c = -------------------------- = £2.38

So hmmm notice the picture below

thus $\bf \textit{volume of a rectangular prism}\\\\
V=lwh\qquad 
\begin{cases}
l=length\\
w=width\\
h=height\\
----------\\
l=100\\
w=20\\
V=225,000

Answer:

0.0025551

Step-by-step explanation:

Given that:

Mean (m) = 40000

Standard deviation (s) = 2500

P(x < 33,000) :

USing the relation to obtain the standardized score (Z) :

Z = (x - m) / s

Z = (33000 - 40000) / 2500 = - 2.8

p(Z < -2.8) = 0.0025551 ( Z probability calculator)

Probability of Tyre wagering out before mileage limit is reached = 0.0025551
