The amount of interest paid will be $396.6.
What is simple interest?The simple interest is the simple amount paid by the borrower to the bank according to the percentage set by the bank for per year which is a fixed interest rate.
Given that Margo takes out a $600 loan with a 10-month repayment period and a 2% yearly interest rate.
The simple interest will be calculated as:-
SI = ( P x R x T ) / 100
SI = ( 1100 x 9 x 4 ) / 100
SI = 39600 / 100
SI = $396

The balance in the account after 1 year due to continuous compounding is approximately $1030.45 and AYP is 3.04%.
What is meant by continuous compounding?
If compound interest is calculated and reinvested into the balance of an account across an essentially unlimited number of periods, continuous compounding is the mathematical limit that compound interest can reach. Continuous compounding determines interest by assuming constant compounding across an infinite number of periods, as opposed to computing interest on a finite number of periods, such as annually or monthly.
Given,
rate per period = 3%
Principal amount = $1000
Compounding is done after 1,5 and 20 years.
But we are asked to find the amount after continuous compounding after 1 year.
The formula of the amount after continuous compounding is:
[tex]A = Pe^{rt}[/tex]
where A = amount after continuous compounding
r = rate of period
t = time period
P = principal amount
[tex]A = Pe^{rt} = 1000e^{0.03*1}[/tex] = $1030.45
Annual yield formula (AYP) = [tex](1+\frac{r}{n} )^n-1[/tex]
n = times it compounds per year = 365
r = 0.03
AYP = [tex](1+\frac{0.03}{365} )^{365}-1 = 0.0304[/tex]
= 3.04%
Therefore The balance in the account after 1 year due to continuous compounding is approximately $1030.45 and AYP is 3.04%.

6. There are marbles of four different colors in a bag. The
ratio of red to white to blue marbles is 3:4:5. There are half
as many green marbles as there are blue marbles. What is
the least possible number of marbles in the bag?
(A) 12
(B) 24
(C) 29
(D) 58
Answer:
(C) 29
Step-by-step explanation:
Answer:
the least possible number of marbles in the bag is 12.
Step-by-step explanation:
As for the question about the marbles, let's call the number of red marbles "x". Then the number of white marbles is 4x, the number of blue marbles is 5x, and the number of green marbles is (1/2) * 5x = 2.5x.
The total number of marbles in the bag is x + 4x + 5x + 2.5x = 12.5x.
To find the least possible number of marbles, we need to find the smallest possible value of x, which will give us the smallest total number of marbles. Since x represents the number of red marbles, it must be a positive integer. The smallest positive integer value of x is 1.
So, if there is one red marble, there are 4 white marbles, 5 blue marbles, and 2.5 green marbles. The total number of marbles in the bag is 1 + 4 + 5 + 2.5 = 12.5.
Therefore, the least possible number of marbles in the bag is 12.

Sami is 5 feet 8 inches tall and his younger sister is 4 feet 11 inches tall. How many inches taller is sami than his sister?.
The number of inches Sami is taller to his younger sister as per their respective given heights is equal to 9 inches.
Height of Sami in feet and inches is equal to 5 feet 8 inches
Height of Sami's younger sister is equal to 4 feet 11 inches
Convert all height into inches we get,

4 feet = 4 × 12 inches
= 48 inches
Number of inches Sami's is taller than his younger sister is equal to

Population increase in India India had one billion people in 2001. Its growth rate was 1.8% per year. By how many people did the population increase the first year?
The population increased by 18 million at the end of one year at the rate of 1.8%.
What is percentage?The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. Alternatively put, it is the relationship between a component and a whole in which the value of "whole" is always assumed to be 100.
For instance, if a student receives 15 out of 50 in math, one can determine the relevant percentage by expressing "marks earned" as a fraction of "total marks" and multiplying the result by 100. i.e., the percentage of marks is equal to 15 / 50 100, or 30%.
Given that, population of India is one billion.
The rate of increase is 1.8%.
After one year the population will be:
P = (1000000000)(1.8/100)
P = 18000000
Hence, the population increased by 18 million at the end of one year at the rate of 1.8%.

What is the percentage?
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Frequently, it is indicated with the per cent sign, "%". A percentage is a number without dimensions and without a standard measurement.

So basically, the general vertex form of any equation is x = a(y - k)² + h
⇒ y²-4y-x+9 = 0
Shifting the x to RHS,

What is quadratic equation?
A quadratic equation is a polynomial equation of degree 2, which means that the highest power of the variable in the equation is 2. The general form of a quadratic equation is:
ax^2 + bx + c = 0
where x is the variable, and a, b, and c are constants, with a not equal to 0. The quadratic equation can have two solutions, one solution, or no real solutions, depending on the values of a, b, and c.
Starting with the given equation:
25 = (x + 9)²
We can start by taking the square root of both sides of the equation, which gives us:
±5 = x + 9
Next, we can isolate x by subtracting 9 from both sides of the equation:
x = -9 ± 5
This gives us two solutions:
x = -9 + 5 = -4
or
x = -9 - 5 = -14
Therefore, the solutions to the quadratic equation 25 = (x + 9)² are x = -4 and x = -14.

If a seed is planted, it has a 95% chance of growing into a healthy plant.
If 7 seeds are planted, what is the probability that exactly 4 don't grow? Round answer to 4 decimal places.
The probability that exactly 4 out of 7 seeds planted do not grow is 0.0007 (approximately), given that each seed has a 95% chance of growing into a healthy plant.
Calculating the probability of a specific outcome using the binomial distribution formula.The probability that a seed doesn't grow is 1 - 0.95 = 0.05.
To calculate the probability that exactly 4 seeds don't grow out of 7, we need to use the binomial distribution formula, which is:
P(X=k) = C(n, k) * [tex]p^k[/tex] * [tex](1-p)^{(n-k)}[/tex]
where:
X is the random variable representing the number of seeds that don't grow.
k is the specific number of seeds that don't grow (in this case, k=4)
n is the total number of seeds planted (n = 7)
p is the probability that a seed doesn't grow (p=0.05)
C(n,k) is the number of ways to choose k items out of n, also known as the binomial coefficient.
Plugging in the values, we get:
P(X=4) = C(7,4) * 0.05⁴ * 0.95³
