X² -3x -10
x -5
x 2
(x - 5) (x + 2) = x² -3x - 10
x² +2x -5x -10
simplify
x² -3x -10 True
your answer is D.(x+2)
hope this helps
Assuming he had not dealt with the bank offering plan B before, he has nothing deposited two years back. Hence plan B only gives him only 0.2% annual interest for his deposit.
Plan A gives 0.25% for his deposit all the time.
So plan A is more advantageous.
For durations,
To reach $1,000,000 from $100,000, the money needs to grow 10 fold, or
(1+i)^n=10
n=log(10)/log(1+i).
So for plan A:
n=log(10)/log(1.0025)=922.18 years, while for
plan B
n=log(10)/log(1.0020)=1152.44 years.
Hope the bank(s) still exist at that time.
Answer:9
Step-by-step explanation:
Answer:
Given below
Step-by-step explanation:
First we state the objective of our research, whether what we have to find out.
Then we choose a random sample.
Then we collect the data about it, sort it and find out the statistics like mean etc.
The fourth step is to infer population parameters based on sample statistics.
The last step is to draw conclusions whether our objective is proved or not or what we can deduce from the results.
In this experiment the steps are as follows.
1) it is required to study how many hours households have internet usage.
2) The random sample in this experiment is 50000 households.
3) Finding out how many hours a day the household spends streaming video from the internet by asking from different households and then finding the mean etc.
4) The population mean prediction in this experiment depends on the sample mean.
5)The conclusion is drawn that how many hours a day the household spends streaming video from the internet.
