We can find the solution to a system of equations by graphing them and finding where they intersect each other.
In this case, they intersect at the point (2, 3).
To find the probability, we can mutiply the probability of Sue choosing a black dress(40%) by the probability their parents will approve(30%).
The probability would be:
40%×30%
=0.4×0.3
=0.12
=12%
Therefore the probability that Sue chooses ablack dress and her parents approve is 12%.
Hope it helps!
Answer:
Quadrant III
Step-by-step explanation:
Quadrants are numbered in a counterclockwise order starting at the top. Since both numbers are negative, it would fall into the lower left quadrant, also known as quadrant 3.
If a triangle is inscribed in a circle such that one side of that triangle is a diameter of the circle, then the angle of the triangle that is opposite the diameter is a right angle.
Therefore we have the equation:
5x = 90 <em>divide both sides by 5</em>
x = 18
