In this case, the complement would be selecting a number less than or equal to 7; the probability of this occurring is 
Answer:
I know it is 13
Step-by-step explanation:
hope you get it right
Let's assign some random values to it, and say 1 unit of petroleum costs 100 bitcoins, because we all know bitcoins are the best currency :P
If the price goes up by 10%, it is now 100*1.1 = 110bitcoins for 1 unit.
However he's only getting 0.9 units now, so multiplying 110 by 0.9 gives us 99 bitcoins. His petroleum bill used to be 100 (which is why I picked 100 as it's easier), and now it is 99. Therefore his petroleum bill has reduced by 1%
Answer: r= 1.22
Step-by-step explanation:
Formula for amount with simple interest = 
, where
P= principal value , r= rate of interest , t = time.
Given: P= $2000, t= 5 years, r= 1.25% = 0.0125

Formula to compute compound amount : 

When both have same worth then

taking log on both sides , we get

Hence, Value of r= 1.22
Answer:
See the distances bellow
Step-by-step explanation:
Given data
D(-5, -6), E(5, 2)
substitute into the expression for the distance

E(5, 2), F(4, -4)

F(4, -4), G(-6, -12)

G(-6, -12), D(-5, -6)
