Step-by-step explanation:
Given a right angled triangle ABC, with a right angle at A.
<ABC =
<BCA =
AC = 9 = 1
CB = 18 = 2
Applying Pythagoras theorem to ΔABC, we have;
AB =
=
=
Thus applying the trigonometric ratios, it would be observed that;
i. sin(C) =
ii. tan(C) =
iii. sin(B) =
Answer:
$44.90
Step-by-step explanation:
The resulting value for the company of replacing a failed product is given by the price of the warranty minus the cost of replacement:
This event has a 0.7% chance of happening.
The resulting value for selling extended warranty to a product that does not fail is given by the proce of the warranty:
This event has a 99.3% chance of happening.
