The probability that in any one sample, two calculators or less will be faulty is; 100%
<h3>Probability and Random sampling</h3>
According to the task content;
- A statement of fact indicates that; 20% of the calculators produced in a factory are faulty.
Hence, it follows that, when a sample of 10 calculators is selected randomly each day, 2 of the calculators are faulty by proportion.
Ultimately, the probability that in any one sample, two calculators or less will be faulty is; 100%.

Answer:
The correct option is y ≤1/3 x – 4
Step-by-step explanation:
If you look at the attached graph you will see that the inequality is the shaded area below the solid line.
The slope of the line is positive which is 1/3.
The y intercept is equal to -4
Thus the inequality must be:
y ≤1/3 x – 4
Therefore the correct option is:
y ≤1/3 x – 4 ....
Answer:
f^-1(x)=1/2x+5
Step-by-step explanation:
y=2x-10
inteechange 'y' with 'x'
x=2y-10
make 'y' the subject
2y=x+10
divide by 2both sides
y=(x+10)÷2
y=1/2x+5
f^-1(x)=1/2x+5
Answer:
