Answer:
0.5.
Step-by-step explanation:
Number of red marbles = 50
Yellow marble = 40
Green marble = 10
Total number of marble = 50+ 40 + 10 = 100
Probability of getting yellow marble =
= 0.4
Probability of getting green marble =
= 0.1
Probability of getting either red or green marble = 0.4 + 0.1 = 0.5
Hence, the required probability is equal to 0.5.
Answer:
The Correct option is C ) 25
Therefore the value of x is 25 when y =40.
Step-by-step explanation:
Given:
Variable 'y' is directly proportional to the variable 'x'.
......Direct Variation
Where,
k = Constant of proportionality
To Find:
value of x = ? when y = 40
Solution:
First we need to find Constant of proportionality
When x = 20 and y = 32
Substituting the values we get
Now when k =1.6 , y = 40 then x will be
Therefore the value of x is 25 when y =40.
