Answer:
n
Step-by-step explanation:
Answer:
t = 1
Step-by-step explanation:
1) Subtract 4 from both sides so you get -2t = -2
2) Divide both sides by 2 so you get t = 1
4(x+2)=4x+8
2(x-1)=2x-2
2(x+1)=2x+2
You use disruptive property when solving equations like this.
Answer:
D
Step-by-step explanation:
Probability that the die will show an even number
in one rolling is 3/6=0,5 = p
We have formula for repeating rolling
n!/(r!(n-r)!) p^r (1-p)^(n-r)
n = how many times we repeat rolling = 6
r = how many times we want something to happen
(show an even number exactly two times) = 2
15 *(0,5)^2 *(0,5)^4 = 0,234375
