Since 10 out of 14 marbles are green, the probability of selecting a green marble is 10/14=0.714.

Similarly, the probability of selecting a red marble would be 4/14.

Answer: 0.714

What two numbers multiply to equal 50 and add up to equal -15
Tanzania [10]

The two numbers are 5,10. Which is multiply to equal 50 and add up to equal 15.

Step-by-step explanation:

Step:1

      Let, X,Y.

      Where X, Y are two numbers.

Step:2

      Form the Multiplication equation from given,

     X×Y=50         (∵ Multiply to equal 50)

Step:3

      Form Addition equation from given,

      X+Y= 15        (∵ Add equal to 15)

Step:4

      Check for alternatives to satisfy both equations

     Assume, X=1, Y=14

     1+14=15 (Satisfy addition equation)

     1×14=14 (Not satisfy multiplication equation)

     Assume, X=2, Y=13

     2+13=15  (Satisfy addition equation)

     2×13=26 (Not satisfy multiplication equation)

similarly.,

    assume X=5, Y=10

    5+10=15   (Satisfy addition equation)    

    5×10=50  (Satisfy multiplication equation)

So, the two numbers are 5,10.

Drag the coordinates to match the coordinates of each point on the left with the coordinates of its reflection across the x-axis
fredd [130]

Answer:

1. (-2,-7)

2. (3,-9)

3. (7,-2)

4.(-3,9)

Step-by-step explanation:

Since the reflection is across the x-axis, the y-coordinate will be flipped.

Example: (-7,4) would become (-7,-4)

HOWEVER, if the reflection is across the y-axis, the x coordinate will be flipped.

Example: (-7,4) would become (7,4)
