Answer
Step-by-step explanation:
Let x be the fasteners
95% of x passed, and 5% of x failed
20% of the 5% which failed are defective, remaining the 80% of the failed 5%.
Now 40% of this 80% of the 5% which failed are scrapped, meaning only the remaining 60% passed second inspection.
Thus
a). The proportion ;
60% of 80% of 5% of x
mathematically
= 60/100 × 80/100 × 5/100
= 0.024 or 2.4%
b) initially 95% passed and later on 2.4% pass again. Therefore total that passed = 95%+2.4%=97.4%
c) probability that it passed on first inspection is 95/100
Percentage that went through recrimping = 80% of 5% = 80/100 × 5/100 = 1/25 or 0.04 or 4%
Thus probability of passing and not going through recrimping
= 1 - (1/25) = 0.96 or 96%

Step-by-step explanation:
The area of semi-circle is 8π cm² with diameter of 8cm.
What is area of semi-circle?
- The area that the semicircle occupies is that which is contained inside its perimeter. Half of a circle is a semicircle.
- The area of a semicircle will therefore be equal to half that of a circle. Both the radius and the diameter can be used to get the semicircle's area.
- The formula used to determine a semicircle's area in terms of radius "r" is written as follows:
Area of circle = πr²/2
- Area of semi-circle= πd²/8 is the formula used to determine a semicircle's area in terms of its diameter.
- The value of the constant is 22/7, or 3.14.
Given:
Diameter = 8cm
Area of semicircle = πd² / 8
=π8² / 8
= 8π cm²
Hence, the area of semi-circle is 8π cm².
