Find the future value if you invest $1200 at 5.25% compounded quarterly for two years.
In accordance with the compound interest model, the future value if you invest $ 1200 at 5.25 % compounded quarterly for two years is $ 1807.
How to determine the current capital by compound interest model
The compound interest model is based on the assumption that the initial capital obtain gains continuously in time. This model is represented by the following expression:
C' = C · (1 + r/100)ˣ (1)
Where:
C - Initial capitalC' - Current capitalr - Interest ratex - Time, in quartersPlease notice that a year consists in four quarters. If we know that C = 1200, r = 5.25 and x = 8, then the current capital is:
C' = 1200 · (1 + 5.25/100)⁸
C' = 1807

During a cash poker game, a professional gambler bets $6,000 on the cards in his hands. The bet has a 0.81 probability of producing a large profit of $6,500, a 0.08 probability of producing a small profit of $200, and a 0.11 probability of producing a loss of $6,000. If the gambler were to continue making bets with this probability distribution, what would his expected profit be?
The expected profit for the gambler is $4,621

What is the quotient of this equation
Answer:

Step-by-step explanation:

Next, we know that when dividing fractions, there is a certain pattern to follow.
It goes like this:

[tex]\frac{20}{3}\times\frac{9}{2} \\\\\frac{180}{6}\\\\\ =30[/tex]
Answer:
Hello! the answer to this question is 30.
Step-by-step explanation:
To solve for the quotient, we have to convert the mixed number to an improper fraction:
[tex]6\frac{2}{3} = \frac{6*3 + 2}{3} = \frac{20}{3}[/tex]
When dividing fractions, we have to flip the divisor to its reciprocal. When doing so, the divisor [tex]\frac{2}{9}[/tex] becomes [tex]\frac{9}{2}[/tex].
Now that we have the reciprocal, the operation will change from division to multiplication. We can take the final steps to solve the problem:
[tex]\frac{20}{3} * \frac{9}{2}[/tex]
This leaves you with a result [tex]\frac{180}{6}[/tex]. This can further be simplified by doing 180 ÷ 6 to get 30.
Therefore, the quotient is 30.

If there are eleven people on the team and nine positions, how many total arrangements of the players can be made? if amy does not want to play pitcher, then there are now people available to pitch. assuming the pitcher has already been chosen, there are ten remaining players and remaining positions. how many ways are there to arrange the remaining players and positions?
There are 19958400 ways if 9 people are selected for positions and if Amy does not want to play then the number of ways will be 1814400 if done through permutations.
Given there are 11 people and nine positions.
We have to find the number of ways in which arrangement can be done if there are 11 people and 9 positions and the number of ways to arrange if Amy doe not want to play assuming the pitcher has already been chosen.
Permutations helps us to know the number of ways an object can be arranged. It is denoted by n[tex]P_{r}[/tex]=n!/(n-r)!
where n is the number of choices available,
r is the choices.
Given that the team has 11 players while there are only 9 positions available, the number of ways is 11[tex]P_{9}[/tex]=11!/(11-9)!
=11!/2!
=19958400
Now Amy does not want to play, therefore the number of ways the remaining people can be arranged in the place of pitcher is 10. Also the positions has also decreased from 9 to 8.
Thus the number of ways in which remaining people can be arranged are: 10[tex]P_{8}[/tex]=10!/(10-8)!
=10!/2!
=1814400
Hence the number of ways in which 11 people are arranged is 19958400 and the number of ways in which the remaining players are arranged is 1814400.

108 centimeters to meters
Answer:
1.08 Meters
Step-by-step explanation:
Simply, divide the length value by 100.
So in this case, the length value is 108.
So 108 ÷ 100 would be equal to 1.08.
This would mean moving the decimal points to places to the left would give you your answer.
Therefore, 108 centimeters is 1.08 meters.

Which of the following functions are continuous?
Answer:
B. I, II, and III
Step-by-step explanation:
A function is continuous if it is defined everywhere and its graph can be drawn without lifting the pencil. That is, at every point, the limit from the left and the limit from the right must equal each other and the function definition at the point.
Looking at choicesAll polynomial functions with real coefficients are continuous everywhere. (Choices I and II.) They have no discontinuities.
Rational functions will have a discontinuity wherever the denominator is zero. Here, the one rational function has a denominator of x^2+1, which is always positive (never zero). The given rational function is continuous everywhere (Choice III.)
All of the functions in the problem statement are continuous: I, II, and III.

⇒ ∠ EGF = 180° - 90° - 26°
⇒ ∠ EGF = 64°
• ∠ DGE + ∠ EGF = 90° [as shown in the diagram]

A. 2.14
B. 2.85
C. 4.75
D. 8.55
Answer:
B. 2.85
Step-by-step explanation:
to find the average of multiple numbers, we add them together and divide by the number of values we combined
for example: the average of 1, 2, and 3:
1 + 2 + 3 = 6
6 / 3 (because there were 3 numbers) = 2
so, this average would be 2.
Let's add the weights (I have changed these into a denominator of 20, so that they can be easily added. Let me know if you need clarification on how I did so)
1 1/2 pounds, 4 3/4 pounds, 2 3/10pounds
1 1/2 = 1 10/20
4 3/4 = 4 15/20
2 3/10 = 2 6/20
1 10/20 + 4 15/20 + 2 6/20 = 7 31/20
7 31/20 = 8 11/20
8 11/20 = 8.55
8.55 / 3 = 2.85
so, the average weight of these packages is 2.85 [pounds]
