D. There is a 5/8 chance each time. You would multiply that together to get the answer seen in D.
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
3x +2y = 5 → (1)
x - 2y = - 1 → (2)
Adding the 2 equations term by term will eliminate the term in y, that is
(3x + x) + (2y - 2y) = (5 - 1)
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 in either of the 2 equations and solve for y
Substituting in (1)
3(1) + 2y = 5
3 + 2y = 5 ( subtract 3 from both sides )
2y = 2 ( divide both sides by 2 )
y = 1
Solution is (1, 1 )
Answer:
$23,330.66
Step-by-step explanation:
The compound interest function is ...
FV = P(1 +r/n)^(nt)
where P is the principal amount ($19,600), n is the number of compoundings per year (4), r is the interest rate (.035), and t is the number of years (5).
Putting these numbers into the formula and doing the arithmetic, we get ...
FV = $19,600(1 +.035/4)^(4·5) = $23,330.66
