Answer: 25%
Step-by-step explanation:
You have a 1/2 chance of landing a heads or tails both times. So, you multiply 1/2 *1/2 = 1/4. 1/4 = 0.25 = 25%.
Answer:
x · -4
Step-by-step explanation:
-2×-4=8
8×-4=-32
-32×-4=128
The process is also known as recurssion which is most often the term used in computer science.
Both terms mean that you do something to the previous term to get to the next term. In general terms it is written like this
fn = f_(n - 1) + d for an arithmetic progression. The series begins with n =2 , 3 , 4 , 5 , 6 ...
f1 is defined as 7
so f2 = f_(2 - 1) - 2 or
f2 = f_1 - 2
f2 = 7 - 2
f2 = 5
f3 = f_(3 - 1) - 2 or
f3 = f_2 - 2
f3 = 5 - 2
f3 = 3 and so on. Computers handle this much better than people do. They can go through a thousand such calculations most of the time in less than a second.
First car: $10 + 3 every mile
Second car: $20 + 2 per every mile
For the part that says "Write an equation that represents the cost of
each car service and determine when they cost the same.", find the LCM of 13 and 22.
