A box of marbles contains 20 red marbles, 15 blue marbles, 13 orange marbles, and 12 white marbles. What is the probability that if a marble is selected at random, the marble will be blue? a 0.25
b 0.33
c 0.20
d 0.15

a

Step-by-step explanation:

becuase 15/60 = 0.25

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
