Answer:
a ) See Annex
b) P₁ = 0,0464 or P₁ = 4,64 %
c) P₄ = 0,92 or P₄ = 92 %
Step-by-step explanation:
b) P₁ [ X being defective ] = P₂ + P₃
Where P₂ is the probability of X rays machine detects a weld defective and the weld is really defective
And P₃ is the probability of X rays machine detects a weld defective and the weld is not defective
Then
P₂ = 0,04 * 0,92 = 0,0368
P₃ = 0,96 * 0,01 = 0,0096
Then P₁ = 0,0368 + 0,0096
P₁ = 0,0464 or P₁ = 4,64 %
c) P₄ = 0,04 *0,92
P₄ = 0,92 or P₄ = 92 %
Answer:
$54.73 monthly installment for 6 months.
Step-by-step explanation:
Kevin just bought a refrigerator for $469.
He paid $140.6 in down payment and will pay the rest in equal installments.

Answer:
93.7 miles
Step-by-step explanation:
This problem can be represented as a right angled triangle. The distance between the final point and the starting point is the hypotenuse.
We need to find the hypotenuse. We can use Pythagoras rule:
where opp = opposite side to the angle considered
adj = adjacent side to the angle considered
This implies that:
The car is 93.7 miles far from its starting point.
