Answer:
$12000 at 5%
$27000 at 6.5%.
Step-by-step explanation:
Let x represent amount invested at 5% and y represent amount invested at 6.5%.
We have been given that a combined total of 39000 is invested in two bonds. We can represent this information in an equation as:
We are also told that the annual interest rate is 2355.00. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, an amount of $12,000 is invested at 5%.
Upon substituting in equation (1), we will get:
Therefore, an amount of $27,000 is invested at 6.5%.
Answer: It has systematic sampling.
Step-by-step explanation:
Systematic sample is a method of statistics which includes the selection of elements from the ordered sampling.
It has equal probability of each element.
It is done by choosing the starting point and selecting other elements after fixing the systematic or periodic interval.
She randomly selects the sixth name as a starting point and then selects every 100th subsequent name (106, 206, 306, etc.)
So, Sixth name is the starting point and then choosing the other elements after fixing an interval of 6.
So, it has systematic sampling.
I took five years before and it was hard for me to remember the postualates. I found it helpful to practice proving problems that involved the postualate. Some postualates like SAS are just abbreviations. SAS- Side-Angle-Side
Y-y=m(x-x). That is the formula for point slope form. You want to take the two y axis and subtract them from each other and m is your slope. Then u take the x axis put them in parentheses and then you u solve with pemdas from the there.
