Margo borrows $200, agreeing to pay it back with 4% annual interest after 6 mobths. How much interest will she pay?
Answer:
$3.96
Step-by-step explanation:
Use the formula:
[tex]p(1+\frac{r}{n} )^{nt}[/tex]
p is our initial investment
r is the interest rate
n is the term
t is time
doing this we get
[tex]200(1+\frac{.04}{1})^{0.5}[/tex]
where t = 0.5 because the term is 6 months or half a year
We get a value of 203.96 which is the amount of money being paid after 6 months.
The interest is then our initial value of $200 subtracted from our final value.
[tex]203.96-200= 3.96[/tex]

3 $26,000 $9,360 $16,640 $3,328 $12,688 $13,312
What is the double-declining-balance method?
One of the depreciation methods in use is the double-declining-balance method, however it places more expense in the initial years of an asset's life.
The straight-line rate, which is calculated as the product of 100/estimated useful life multiplied by 2, is doubled in this depreciation technique.
The double rate is applied to the remaining balance at the end of each year for the depreciation expense.
The depreciation expense for the most recent year is calculated as the difference between the ending balance from the prior year and the residual value.
Auto = $26,000
Estimated useful life = 10 years
Residual = $600
Depreciable amount = $26,000 - $600 = 25,400
Straight-line depreciation rate = 100/10 = 10%
Double-declining depreciation rate =10% x 2 = 20%
Depreciation Expense:
1st year = 26000 x 20/100 = 5200
2nd year = 20800 x 20/100 = 4160
3rd year = 16640 x 20/100 = 3328
4th year = 13312 x 20/100 = 2662.40 = 2662
5th year = 10650 x 20/100 = 2130
6th year = 8520 x 20/100 = 1704
7th year = 6808 x 20/100 = 1361.6 = 1361

Which expression shows the greatest common factor of these three values using the distributive property?
The correct option is A . 12(3+2+4) shows the greatest common factor of these three values using the distributive property
What is gcf ?A factor is an integer in mathematics that, when multiplied by other integers, produces the desired results. The resultant total is also known as the factors. The numbers can often be combined in a broad variety of ways. If you are familiar with the multiplication tables, it will be simple for you to determine the factors.
When two or more numbers are combined, the largest number is the greatest common factor (GCF). They are divided by the biggest number, which yields a natural number (factor). There are a few things that both share once all the variables that effect the number have been identified. The term "largest common factor" refers to the common factor among the others having the highest number.
CalculationThe product of the common prime factors of 2 or more numbers is the greatest common factor(GCF) of the numbers.
Using the distributive property, it can be written that .a(b+c) = ab + ac
Step 2
Write each number as the product of its prime factors. The product of the common factors is the greatest common factor(GCF) of the numbers.
The numbers,36 , 24 , 48 can be factored as follows.
36 = 2 * 2 * 3 * 3
24 = 2 * 2 * 3 * 2
48 = 2 * 2 * 3 * 2 * 2
Hence, the greatest common factor(GCF) of these numbers is equal to
2 * 2 * 3 or 12 .
Take out the greatest common factor(GCF), 12 from the expression, 36+24+48 using the distributive property to obtain the result.
36+24+48 = 12 * 3 + 12 * 2 + 12 * 4
= 12 ( 3 + 2 + 4 )
Hence, the correct option is A .
Option B is incorrect as the factored out term is 6, which is not the greatest common factor(GCF) .
Option C is incorrect as the factored out term is 4, which is not the greatest common factor(GCF) .
Option D is incorrect as the factored out term is 3, which is not the greatest common factor(GCF) .

a. -$1250/year
b. -$950/year
C. -$150/year
d. $150/year
The rate of change at which the value of the auto is -950/year.
What is the Rate of Change?
It is said that the rate at which one quantity changes in relation to another is known as the rate of change function.
In simple terms, when calculating the rate of change in one item, the amount of change in another is divided by the comparable amount of change in another.
From the given data of question,
[tex]V(t) = 24000*0.95^{t}[/tex]
Then, by definition, the rate of change =[tex]\frac{d(v(t))}{dt} = \frac{d(24000*0.95^{t} )}{dt}[/tex]
= [tex]24000*0.95^{t}*ln(0.95)[/tex]
For time (t) = 5 years
[tex]\frac{d(v(t))}{dt} = 24000*0.95^{5}*ln(0.95)[/tex]
= 24000*0.7737*(-0.0512)
= -950
Hence, the rate of change of the value of the auto is -950/year.

Standard deviation of two sets:
Answer:
A = {1,2,3,4,5}
B = {5,6,7,8,9}
========================================================
Explanation:
Consider the set
A = {1,2,3,4,5}
The mean is found by adding up all the values to get 15, then divide by the number of values (5) to get 15/5 = 3
The standard deviation is a bit more complicated, and it depends which version you select (sample vs population). Let's say we go for the population standard deviation. Using a calculator gets us a population standard deviation of roughly 1.414; this value tells us how spread out the data set is. The higher the value, the more spread out the data set will be.
Now consider adding some fixed value to each item in set A. Let's add 4 to each value
We go from A = {1,2,3,4,5} to B = {5,6,7,8,9}
If you were to use a calculator, then the population standard deviation is still roughly 1.414 but the mean is now 7. The standard deviation hasn't changed because the values are still spread out the same way.
Note: infinitely many answers are possible for sets A and B.

What would be the 5 number summary for this data: 18,19,21,23,23,23,24,25,25,31 ?
The 5-number summary of the given data is as follows:
Minimum: 18Quartile Q1: 20.5Median: 23Quartile Q3: 25Maximum: 31What is 5 number summary?A set of descriptive statistics called the five-number summary is used to describe a dataset. When conducting descriptive analyses or conducting an initial analysis of a sizable data set, a five-number summary is particularly helpful. The maximum and minimum values in the data set, the lower and upper quartiles, and the median make up a summary's five values.The lower or first quartile of the first group's median is equal to (0 + 1)/2, or 0.5. The median for the second group is (27 + 61)/2, which is 44. This value represents the upper or third quartile. Observations 0 and 63 are the smallest and greatest values. The five-number summary is therefore 0, 0.5, 7.5, 44, 63.So, the data set is:
18,19,21,23,23,23,24,25,25,31Then, the 5-number summary will be:
