The triangular region shows the number of possible ounces of gold, x, and the number of possible ounces of silver, y, a jewelry maker can mix together to make a certain piece of jewelry. which combination of gold and silver can the jewelry maker use?
a.12 oz of gold and 20 oz of silver
b.10 oz of gold and 10 oz of silver
c.16 oz of gold and 30 oz of silver
d.25 oz of gold and 20 oz of silver

A.12 oz of gold and 20 oz of silver is the correct answer

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
