Answer:
130
Step-by-step explanation:
Angle B = 180 - Angle A
180 - 50 = 130
Answer:
The probability that Karen has bought at least one dented can is 82.5%
Step-by-step explanation:
To know the probability of Karen buying at least one dented can, it's easier to calculate the probability of her not buying any dented can, and we know that:
The probability of a can not being dented is (in the same principle as above, 100%(all cans)-7%(dented cans)=93%(non-dented cans) 0.93.
As the probability of a can being dented or not is independent from each other, we multiply the probabilities:
Now, we calculate the probability of at least one dented can, expressed as a percentage:

Explanation:</h3>
For a system of 2 equations in 2 unknowns, there are 3 cases:
- slopes are different — one solution
- slopes are the same and y-intercepts are different — no solutions
- slopes and y-intercepts are the same — infinitely many solutions
When slopes are different, the two lines intersect at <em>one</em> point, the <em>solution</em>.
When slopes are the same, the lines may be either parallel (different y-intercepts) or the same (same y-intercepts). If the lines are parallel, there are no points of intersection, hence <em>no solutions</em>. If the lines are the same line, they intersect at all points, so there are <em>infinitely many solutions</em>.
