Answer:
x=5,y=5,z=5
Step-by-step explanation:
x=15-y-z
15-y-z-y+z=5
15-2y=5
y=5
x+y+z=15
15-2y+y+z=15
15-10+5+z=15
z=5
x-y+z=5
x-5+5=5
x=5
Answer:
2m↑3
Step-by-step explanation:
The answer is most likely 15ft.
Conditional probablility P(A/B) = P(A and B) / P(B). Here, A is sum of two dice being greater than or equal to 9 and B is at least one of the dice showing 6. Number of ways two dice faces can sum up to 9 = (3, 6), (4, 5), (4, 6), (5, 4), (5, 5), (5, 6), (6, 3), (6, 4), (6, 5), (6, 6) = 10 ways. Number of ways that at least one of the dice must show 6 = (1, 6), (2, 6), (3, 6), (4, 6), (5, 6), (6, 6), (6, 5), (6, 4), (6, 3), (6, 2), (6, 1) = 11 ways. Number of ways of rolling a number greater than or equal to 9 and at least one of the dice showing 6 = (3, 6), (4, 6), (5, 6), (6, 3), (6, 4), (6, 5), (6, 6) = 7 ways. Probability of rolling a number greater than or equal to 9 given that at least one of the dice must show a 6 = 7 / 11
Answer:
Step-by-step explanation:
Rational numbers;
Numbers which can be written in the form of 
or repeating decimal numbers are the rational numbers.
Examples : 1, 2, 
Irrational numbers:
Numbers which can't be written in he form of a fraction or non repeating decimal numbers are the Irrational number.
Example: 
From the given numbers,
Rational numbers: 
, 6.25, 0.01045, 
, 0.424242....
Irrational numbers:
