$ 807.76 is the balance after 3 years by compound interest.
What is compound interest with example?
When you earn interest on both the money you have saved and the interest you have already received, this is known as compound interest.For instance, after a year, if you deposited $1,000 in an account with 1% yearly interest, you would have received $10 in interest. Compound interest allows you to earn 1 percent on $1,010 (principal plus interest), or $10.10 in interest payments for the year, in Year Two.Given
Principal , P = $675
Rate , r = 6% = 0.06
Time = t years
n = 12 (compounded monthly)
(a)
Balance after t years is given as,
A = P(1 + r/n)nt
A = 675(1 + 0.06/12)12t
A = 675(1.005)12t
Balance after t years = 675(1.005)12t
(b)
Balance after 3 years = 675(1.005)12*3
= 675(1.005)36
= 675*1.19668
=807.7593 \approx 807.76
Balance after 3 years = $ 807.76

Answer:
б) не более трех раз
Which expression is equivalent to quantity y raised to the negative second power times z raised to the seventh power end quantity over quantity z raised to the negative third power times y raised to the eighth power end quantity all raised to the negative second power? z raised to the tenth power over y raised to the tenth power y raised to the tenth power over z raised to the tenth power z raised to the twentieth power over y raised to the twentieth power y raised to the twentieth power over z raised to the twentieth power
The expression z raised to the twentieth power over y raised to the twentieth power is equivalent to the expression given in the question.
y raised to the negative second power = [tex]y^{-2}[/tex]
z raised to the seventh power = [tex]z^{7}[/tex]
Thus, in the numerator we have the expression- [tex]y^{-2} z^{7}[/tex]
In the denominator, we will have-
z raised to the negative third power = [tex]z^{-3}[/tex]
y raised to the eighth power = [tex]y^{8}[/tex]
denominator will be = [tex]z^{-3} y^{8}[/tex]
Thus, the expression becomes-
[tex](\frac{y^{-2 }z^{7} }{z^{-3} y^{8} })^{-2}[/tex]
Now, that we've decoded the expression, let us solve it-
[tex]({y^{-2 }y^{-8} z^{7} z^{3} )^{-2}[/tex]
= [tex]({y^{(-2-8) } z^{(7+3)})^{-2}[/tex]
= [tex]({y^{(-10) } z^{(10)})^{-2}[/tex]
= [tex]{y^{(-10*-2) } z^{(10*-2)}[/tex]
= [tex]{y^{(20) } z^{(-20)}[/tex]
= [tex]\frac{z^{20} }{y^{20} }[/tex]
= [tex](\frac{z}{y} )^{20}[/tex]
Thus, the expression z raised to the twentieth power over y raised to the twentieth power is equivalent to the expression given in the question above.

The equation of the line graph in slope intercept form is gotten as;
y = x + 3
What is the equation of the Line in Slope Intercept Form?The general formula for the equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Now, from the given straight line equation graph, we can see that the line crosses the x-intercept at x = -3 and crosses the y-intercept at y = 3. Thus;
When x = 0, y = 3
When y = 0, x = -3
Slope is gotten by using two points and their coordinates to get;
m = (3 - 0)/(0 - (-3))
m = 3/3
m = 1

Step-by-step explanation:
three cards are drwan at random, without replacement, from a standard deck of 52 playing cards. compute the (conditional) probability that the first card drawn is spade, given that the second and third cards have spades.
If the second and third cards have a spade then the probability that the first card drawn is a spade is 21.2%.
Probability can be described as a field of mathematics that determines how likely a thing is to happen. When there is uncertainty about the outcome of an event we consider the probabilities of certain results or outcomes.
There are a total of 13 spades in a deck of 52 playing cards. So if the second and third cards have spades then there are 11 spades remaining.
The formula for probability can be given as;
probability = number of favorable outcomes or events ÷ total number of outcomes or events
probability = 11 / 52 = 0.212
Converting it into percentage;
probability = 0.212 × 100 = 21.2%
Therefore, the probability that the first card drawn is a spade is calculated to be 21.2%.

Write the formula for a meal that has a total cost of C
that is equal to the price of the food F plus 20% (for tip) of
the price of the food.
Answer:
C = F(0.20) + F
Step-by-step explanation:
C is the total cost. F(0.20) will reduce the value of the food to the tip amount required, and then adds the tip value to the price of the food, F.
Example inputs: let F be equal to 10
C = F(0.20) + F turns into C = 10(0.20) + 10
10(0.20) will cause 10 to be multiplied by the tip value, 20%, and 20% is equivalent to 0.20. Once you multiply 10 by 0.20, you get 2. After that, you add 2 to the price of food, which is 10, and you get a total cost of 12.
12 = 10(0.20) + 10

E(penny) = 0.5 and E(nickel) = 1.5, so she should play with the nickels. E(penny) = 1.75 and E(nickel) = 1.5, so she should play with the pennies. E(penny) = 2.38 and E(nickel) = 2, so she should play with the pennies
Using the expected value of a discrete distribution, the correct option is given as follows:
E(penny) = 1.75 and E(nickel) = 1.5, so she should play with the pennies.
What is the expected value of a discrete distribution?The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
When 3 coins are tossed, the probabilities are given as follows:
All heads: (1/2)^3 = 0.125.All tails: (1/2)^3 = 0.125.At least one of each: 1 - 2(0.125) = 0.75.Hence the distribution for the penny points is:
P(X = -2) = 0.25.P(X = 3) = 0.75.The expected value for the penny points is:
-2 x 0.25 + 3 x 0.75 = 1.75.
When 2 coins are tossed, the probabilities are given as follows:
All heads: (1/2)² = 0.25.All tails: (1/2)² = 0.25.At least one of each: 1 - 2(0.25) = 0.50.Hence the distribution for the nickel points is:
P(X = -2) = 0.5.P(X = 5) = 0.5.The expected value of nickel points is:
E(X) = -2 x 0.5 + 5 x 0.5 = 1.5.
Due to the higher expected value, she should play with the pennies and the third option is correct.

assume the cost of a gallon of milk is $2.70. with continuous compounding, find the time it would take the cost to be 4 times as much (to the nearest tenth of a year), at an annual inflation rate of 6%.
The time it would take the cost to be 4 times the current cost of a gallon of milk at an annual inflation rate of 6% is calculated to be 23.8 years.
To determine the time for the cost to be 4 times the current cost of a gallon of milk, we use the compound interest formula as follows;
A(t) = A(0) (1 + r)^t
Here A(t) is the cost of 4 times the current cost at time t
A(0) is the current cost
r is the interest rate
t is the time period
Therefore;
2.70 × 4 = 2.70( 1 + 0.06)^t
2.70 × 4 / 2.70 = (1.06)^t
4 = (1.06)^t
Taking log on both sides;
t × log(1.06) = log 4
t = log 4 / log(1.06)
t = 23.791 = 23.8 years

Fixed costs = $ 1329.50 per month
Variable cost are $3.70 per set of napkins
Total cost she set aside = $1870 for monthly costs
Amount left for napkins = Total cost - Fixed Cost

$540.50 she can spend on napkinsCost for one set = $3.70
Let set of napkins = x
Total cost for napkins = $540.50
x × 3.7 = 540.50 x = 540.50 / 3.70x = 146.08 (approx) or 147 setsTherefore , she can afford to make 147 (approx) sets of napkins per month.

Predicted Rating (y) =
0.5 (2.5)² - 2.6 (2.5) + 8.9 [Substitute x into the function]
y= 0.5 (6.25) - 2.6 (2.5) + 8.9 [Expand the brackets]
y= 3.125 - 6.5 + 8.9
y= 5.525
Hence the predicted rating in two decimal places is 5.53. This means that the symptoms have been reduced by at least 50%.
