Answer: 
Step-by-step explanation:
When we throw a die , Total outcomes =6
When we throw 3 dice , Total outcomes = 6 x 6 x 6 = 216 [by fundamental counting principle]
Given : Three fair dice are rolled, one red, one green and one blue.
Favorable outcomes : When the upturned faces of the three dice are all of different numbers i.e. no repetition of numbers allowed
By Permutations , the number of favorable outcomes = 
The probability that the upturned faces of the three dice are all of different numbers = 

The probability that the upturned faces of the three dice are all of different numbers is
.
1) (f + g)(2) = 7 + 3 = 10 The answer is C
2) (f - g)(4) = 11 - 15 = -4 The answer is A
3) f(1) = 2(1) + 3 = 5 g(1) = 1² - 1 = 0 The answer is D
4) (f xg ) (1) = 7/3 The answer is B
Answer:
x = 4, hope this helps!
Step-by-step explanation:
2x + 3 = 4x - 5
-2x -2x
3 = 2x -5
+5 +5
8 = 2x
divide by 2 on both sides
4 = x
switch where the x and 4 is, because teachers seem to like that
x = 4
4.438 rounded to the nearest tenth is 4.4
Answer:
x = 20
Step-by-step explanation:
added together, the angles make 180
3x + 80 + 2x = 180
subtract 80 from both sides of the equation
3x + 80 - 80 + 2x = 180 - 80
combine like terms
5x = 100
divide both sides by 5
5x/5 = 100/5
x = 20
