A bag contains only red and blue marbles. Yasmine takes one marble at random from the bag. The probability that she takes a red

marble is 1 in 5. Yasmine returns the marble to the bag and adds five more red marbles to the bag. The probability that she takes one red marble at random is now 1 in 3. How many red marbles were originally in the bag?

There was originally one red marble in the bag because at first the probability was 1 in 5 therefore the other 4 were blue and there was only 1 red

What strategy would you use to find a vertex on a graph, on a table or of an equation? How are these strategies different?
Gemiola [76]

Hey there! :D

To find a vertex on a graph, you would need to look at where the line stops. This place where there is a distinct curve or stopping point and at least one line is going infinity in one direction is the vertex. The graph is much easier than any other method, because it is visual. If I was looking at the vertex on a table, I would see (especially on a quadratic) if there was a pattern to the points. Most points are opposite of each other, so it can be helpful to look at a pattern. In an equation, a parent function can help to see where the vertex is, as well (for quadratics) finding the line of symmetry with the equation to find the vertex. (-b/2a) The strategies are very different, some are easier than others. For example, I would much rather look at a graph for a vertex then do an equation to find it. Some involve looking, seeing a pattern, and others solving. They are all very different but can all be extremely helpful!

I hope this helps!

a quadratic equation has zero real number solutions. which could be the discriminant value associated with this equation? a. –5
Flauer [41]

Answer: Option 'a' is correct.

Step-by-step explanation:

As we know about the discriminant value i.e.

if we have given a quadratic equation :

ax^2+bx+c=0

then,

discriminant value will be

b^2-4ac

There are 3 properties regarding discriminant value as follows:

1)b^2-4ac>0\\\\means,\\\\\text{ there exists real zeros}\\\\2)b^2-4ac=0\\\\means,\\\\\text{ there exists equal zeroes}\\\\3)b^2-4ac

So, here we need a zero real number solutions i.e. there does not exists any real number.

So,

b^2-4ac=-5

Hence, Option'a' is correct.
