We can see that there are 3,832 yes votes, we did that by using the given ratio.
How many yes votes were there?We know that the ratio of yes votes to no votes was 4 to 3, so from each 7 votes, 4 are yes and 3 are no.
Then if we take the total number of votes, and we multiply it by (4/7), we will get the total number of yes votes.
In this case we know that the total number of votes is 6706, then the number of yes votes is:
(4/7)*6706 = 3,832
There are 3,832 yes votes.

A country's population in 1994 was 182 million. In 2002 it was 186 million. Estimate growth formula. Round your answer to the
the population in 2004 using the exponential
nearest million.
The growth formula for the given population is P = 182eⁿˣ and the population in 2004 is 186.98 million
Growth function:
Basically, the growth function means the pattern of data that shows greater increases with passing time, creating the curve of an exponential function.
Given,
A country's population in 1994 was 182 million. In 2002 it was 186 million.
Here we need to find the growth formula and the population in 2004.
According to the given problem, let us consider that the
final population P,
the starting population A, and
the time passed t.
Here we need to determine the value of the growth factor k.
And it can be calculated using the information for the years 1994 and 2002.
Here we know that, A will be 182 million (the population in 1994), P will be 186 million (the population in 2002), and t will be 8 years (the number of years between 1994 and 2002):
⇒186 = 182eⁿˣ⁸
⇒186/182 = e⁸ⁿ
Now, by applying ln to both sides of the equation:
⇒ln(186/182) = ln(e⁸ⁿ)
Using the laws of logarithms:
=> 8n = ln(186) - ln(182)
=> n = [ln(186) - ln(182)] / 8
=> n = 0.0027
Now, let's use this information to determine P in 2004.
Here the value of A will still be 182 million, but t will be 10 years.
Now, we have to apply these values then we get,
=> P = 182e⁰°⁰⁰²⁷ˣ¹⁰
=> P = 182e⁰°⁰²⁷
=> P = 182 x 1.0273
=> P = 186.98
Therefore, there are 186.98 million in 2004.

What is the total net worth if the banker pays off the student loans?
Answer:
$247,517
Step-by-step explanation:
Hello,
Assets
(Car Value) $29,850
(Savings Account Balance) $12,409
(Treasury Bonds) $10,000
(Checking Account Balance) $19,419
(Home Value) $194,450
29850+12409+10000+19419+194450 = 266128
Liabilities
(Car Loan) $10,560
(Student Loans) $13,824 since the students loans are payed of we don't include it into the final net worth.
(Credit Card Balance) $8,051
10560+8051=18611
assets - liabilities = net worth

The proceeds is $7,566.67 and the effective rate charged by the bank to the nearest is 6.87%.
How to find the effective interest rate?Given data:
Principal = $8,000
Rate =6 1/2% or 6.5%
Term= 300 Days
a. Proceeds
Interest = Principal x Rate x Time
Interest = $8,000 x 6.50% x 300/360
Interest = $8,000 x 0.065 x 0.8333
Interest = $433.33
Now let find the Proceeds:
Proceeds = $8,000 - 433.33
Proceeds = $7,566.67
b. Effective Interest Rate:
Effective Interest Rate = 433.33 / 7566.67 x 300/360
Effective Interest Rate = 433.33 / 6305.56
Effective Interest Rate = 0.0687 × 100

62.79 divided by 23 long division
Step-by-step explanation:
this is a college question ????
and you don't know how to do it ? what happened to you in elementary school ?
there are many different techniques. everybody thinks theirs is the fastest or easiest to understand.
after all, this is just "playing" with numbers, the factors embedded within the dividend.
this is mine. when I was in elementary school, we called this the "long division" :
62.79 ÷ 23 =
we pick the first few positions from the left of the dividend, where we are sure, the divisor fits at least once.
in our case here : 62.
we do an integer divide of 62/23 = 2 (for 3 the dividend would have to be at least 69). this 2 is our first digit of the quotient.
62.79 ÷ 23 = 2
now we multiply the divisor by that digit and subtract the result from the dividend. this gives us a remainder of 16, and we pull down the next position (7) :
62.79 ÷ 23 = 2
- 46
---------
167
now, we pulled the first digit after the decimal point, and we need to set the decimal point there in our quotient :
62.79 ÷ 23 = 2.
- 46
---------
167
now, we repeat the process by integer dividing this new dividend (167) by the divisor (23)
167/23 = 7
this 7 becomes the next digit in our quotient. and we repeat the process of multiplying this by the divisor and subtracting the result from the dividend. this gives us a remainder (6), and we pull down the next digit (9).
62.79 ÷ 23 = 2.7
- 46
---------
167
- 161
----------
69
and again, we repeat by integer dividing the new dividend (69) by the divisor (23)
69/23 = 3
this 3 is the next digit in our quotient.
we multiply it with the divisor and subtract the result from the dividend.
if the remainder is still not 0, we need to repeat the process by pulling the next digit, which would be an invisible 0. and continue.
but luckily, after this the remainder is 0, and we are finished.
62.79 ÷ 23 = 2.73
- 46
---------
167
- 161
----------
69
- 69
--------------
0
so, 62.79 ÷ 23 = 2.73 and 0 remainder.

Step 3: Simplify by dividing the numerator and denominator by their gcf. In this case it is 3. So, 1/3 of 3/8 is 1/8.
Step 4: Now we need to get the division equation of 1/3 x 3/8, for this you do the same thing as if we had to actually solve the division equation with fraction, just for changing multiplication to division instead. I am talking about keep change flip. You keep the first fraction the same. you change the operation to it's opposite ,and you flip the numerator and denominator in the second fraction. When we do this we get our division equation of 1/3 divided by 8/3.
Find the derivative
The derivative of the given function is 4x³ / (x²+1) ²
What is derivative mean?
The rate at which a function changes in relation to a variable Calculus and differential equations issues must be solved using derivatives.In order to determine the rate of change of an interest variable, scientists typically observe changing systems (dynamical systems).They then incorporate this information into a differential equation and use integration techniques to produce a function that can be used to predict how the original system will behave under various conditions.Geometrically, the slope of a function's graph or, more accurately, the slope of the tangent line at a point can be used to understand the derivative of a function.d(u/v) = [ u(dv/dx) + v(du/dx) ] / v²
Given:
f(x) = x²/x²+1
Applying the formulae:
= x²[ d(x²+1)/dx] + (x²+1) [ d(x²)/dx ] / (x²+1) ²
= x²(2x+0) + (x²+1)2x / (x²+1) ²
= 2x³ + 2x³ / (x²+1) ²
= 4x³ / (x²+1)²
