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%.

14/5 is the same as 2 4/5. 5 goes evenly into 14 twice, which gives us the 2. 14-10 is 4, so we have 4/5. I hope this made sense. if it didn't please tell me and i can try to explain it better

Hey!
To find out how much it is in cups, we must know how many cups 1 quart is equal to.
1 quart = 4 cups.
5 1/2 (or 5.5) quarts = 22 cups.
<h3>
Answer: -8</h3>
===================================================
Work Shown:
Q(x) = 4x^2 + 5x - 7
Q(-1) = 4(-1)^2 + 5(-1) - 7 .... replace every x with -1; use PEMDAS
Q(-1) = 4(1) + 5(-1) - 7
Q(-1) = 4 - 5 - 7
Q(-1) = -1 - 7
Q(-1) = -8
