Answer:

Step-by-step explanation:
Amount deducted for Medicare = $725
Amount deducted for state income tax = $3000
Amount deducted for Social security = $3100
To find: Total amount deducted from Alton's pay for FICA last year
Solution:
Total amount deducted from Alton's pay for FICA last year = Amount deducted for Medicare + Amount deducted for state income tax + Amount deducted for Social security = 
On adding 725 and 3000, we get 
On adding 3725 and 3100, we get 
So, amount deducted = 
Rule of 72 says to divide 72 by the rate of return and that will be the number of years an investment will double
so 72 / 9.6 = 7.5 years to double
7.5 * 2 = 15 years
18-3 = 15
the answer is: <span>Yes, the $15,000 will double each 7.5 years. In 15 years, it will double twice.</span>
According
to the empirical rule, if the data form a "bell-shaped" normal
distribution, approximately 99.7 percent of the observations will be contained
within 3 standard deviations around the mean.
<span>
To add, a bell curve is used to describe the mathematical concept called
normal distribution, sometimes referred to as Gaussian distribution. </span>
Answer:
The answer to your question is below
Step-by-step explanation:
Data
Equation 25x² + 64y² = 1600
Process
1.- Divide all the equation by 1600
25x²/1600 + 64y²/ 1600 = 1600/1600
-Simplify
x²/64 + y²/ 25 = 1
2.- Equation of a horizontal ellipse

3.- Find a, b and c
a² = 64 a = 8
b² = 25 b = 5
-Calculate c with the Pythagorean theorem
a² = b² + c²
-Solve for c
c² = a² - b²
-Substitution
c² = 8² - 5²
-Simplification
c² = 64 - 25
c² = 39
-Result
c = √13
4.- Find the center
C = (0, 0)
5.- Find the vertices
V1 = (-8, 0) V2 = (8, 0)
6.- Find the foci
F1 = (-√13, 0) F2 = (√13, 0)
