The length of the rectangle is three times its width.The perimeter of the rectangle is at most 112 cm .
Slav-nsk [51]

Option D is the correct answer

2w+2.(3w)\leq 112

Further explanation:

Let

l\ be\ the\ length\ of\ rectangle\\and\\w\ be\ the\ width\ of\ rectangle

The perimeter of a rectangle is given by:

P=2w+2l

It is also given that:

P\leq 112

So we can write as

2l+2w\leq 112

We also know that The length of the rectangle is three times its width

l=3w

Putting the value of l in the inequality

2.(3w)+2w\leq 112

Rearranging the terms

2w+2.(3w)\leq 112

Hence, option D is the correct answer.

Aleonysh [2.5K]

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
