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%

Answer:
$27.34
Step-by-step explanation:
250 miles divided by 32 miles per gallon equals 7.8125 which is the number of gallons needed. Then multiple 7.8125 by the cost per gallon $3.50 to determine the cost of the fuel needed.
The answer to this would be 3 1/2 but the simplified fraction is 3.5
Answer:
∠3= 180° - m∠1
Step-by-step explanation:
a quadrilateral equals 360° when divide 360° into 4 angles the opposite angles add up to 180° half 360°
