Option C:
It is
throughout the line.
Solution:
Point on the larger shaded triangle are (0, 0) and (–6, –2).
Point on the smaller shaded triangle are (–6, –2) and (–9, –3).
Slope of the line:

Slope of the larger triangle:
Here, 


Slope of the smaller triangle:
Here, 




Both slopes are equal.
It is
throughout the line.
Hence option B is the correct answer.
Answer:
x = 
Step-by-step explanation:
Add 2/3 to both sides.
x+−2/3+2/3=8+2/3
x=26/3

Answer:
It’s an irrational number. 3.08007288, just round it to the nearest whole number and you’ll get 3.
Answer:
a) The probability of falling in the warranty period is 11.6%.
b) The warranty period need to be 19771 km to ensure that no more than 5 per cent of tires fail in the warranty period.
Step-by-step explanation:
a) To fall within the warranty period, the tire has to fail before the 20,000 km.
To calculate the probability, we first calculate the z-value:

Then, the probability of falling in the warranty period is:

b) To calculate this we have to go on from a P(z<z₁)=0.05. This happens for z=-1.645.
This corresponds to a value X of:
The warranty period need to be 19771 km to ensure that no more than 5 per cent of tires fail in the warranty period.
