Answer:
y-determinant = 2
Step-by-step explanation:
Given the following system of equation:
- x + 2y = 5
- x - 3y = 7
Let's represent it using a matrix:
The y‐numerator determinant is formed by taking the constant terms from the system and placing them in the y‐coefficient positions and retaining the x‐coefficients. Then:
y-determinant = (1)(7) - (5)(1) = 2.
Therefore, the y-determinant = 2
Answer:
Tangent line states that a line in the plane of a circle that intersect the circle in exactly one point.
Common external tangent states that a common tangent that does not intersects the line segment joining the centers of circle.
Common internal tangent states that a common tangent that intersects the line segment joining the centers of circle.
Circumscribe polygon states that a polygon with all sides tangent to a circle contained within the polygon.
Therefore:
A polygon with all sides tangent to a circle contained within the polygon = Circumscribe polygon
A common tangent that intersects the line segment joining the centers of circle = Common internal tangent
A common tangent that does not intersects the line segment joining the centers of circle = Common external tangent
a line in the plane of a circle that intersect the circle in exactly one point = Tangent line
Answer:
The correct option is d. 0.60
Step-by-step explanation:
Consider the provided information.
At Mike’s favorite coffee shop, the coffee of the day is either a dark roast, a medium roast, or a light roast.
The coffee being a light roast is 0.15 and the probability of the coffee being a dark roast is 0.25.
Pr(Light roast) = 0.15
Pr(Dark roast) = 0.25
We need to find the probability of the coffee of the day not being a light roast or a dark roast on the next day that Mike visits the coffee shop.
Hence, the correct option is d. 0.60
