The requried lottery commission should make a single deposit of Kenya Shillings 8.7475 million (rounded to 4 decimal places) to fund Peter's annuity.
To calculate the present value of Peter's annuity,
[tex]PV = PMT * (1 - (1 + r)^{-n}) / r[/tex]
where PV is the present value, PMT is the monthly payment, r is the monthly interest rate, and n is the number of months.
In this case, PMT = 87325, r = 0.107/12 = 0.008917, and n = 21*12 = 252.
Substitute the value in the formula given above:
[tex]PV = 87325 * (1 - (1 + 0.008917)^{-252} / 0.008917[/tex]
PV = 8747531.78

A belt runs a pulley at 80 revolutions per minute. Find the angular velocity of the pulley in radians per second.
A belt runs a pulley at 80 revolutions per minute.
(a) To find the angular speed of the pulley in radians per second, we can use the formula
ω = 2πf
Where
ω = angular speed in radians per second
f = frequency in Hertz
We know that the pulley rotates at a rate of 80 revolutions per minute. To convert this to a frequency in Hertz, we can divide by 60 seconds per minute
f = 80 rev/min ÷ 60 min/s = 4/3 Hz
Now we can plug in this value for f into the formula
ω = 2πf = 2π(4/3) = 8π/3 rad/sec
Therefore, the angular speed of the pulley is 8π/3 radians per second.
(b) To find the linear speed of the belt in centimeters per second, we can use the formula
v = rω
Where
v = linear speed in centimeters per second
r = radius of the pulley in centimeters
ω = angular speed in radians per second
We know the radius of the pulley is given in centimeters. Let's assume it is r cm. We just found the angular speed to be 8π/3 radians per second. Now we can plug in these values into the formula
v = rω = r(8π/3) = (8π/3)r cm/s
Therefore, the linear speed of the belt is (8π/3)r centimeters per second.

A. Probability distribution
B. Frequency table
C. Conditional probability
D. Cumulative probability
You can use the notation P(A), read “the probability of event B, given event A” to write a conditional probability. The correct answer is C.
Conditional probability refers to the probability of one event occurring given that another event has already occurred. In this case, we are interested in the probability of event B occurring given that event A has already occurred, and we can represent this using the notation P(B|A), where '|' means 'given'.
For example, let's say we are interested in the probability of getting a head on a coin toss (event B), given that the coin was flipped and landed on heads (event A). We could represent this using the notation P(B|A). The value of P(B|A) would be 1, because if the coin already landed on heads, then the probability of getting a head on the next flip is certain.
Conditional probability is an important concept in probability theory and is often used in real-world applications, such as predicting the likelihood of a disease given certain symptoms, or the probability of an event occurring given certain conditions.

Brooklyn and Matthew both recently got a job and want to start a savings account to earn interest on money they save. Brooklyn's paycheck for was for $625 net pay-after taxes. the bank her parents use offer savings account compounded monthly with an interest rate of 2.5%. Matthews paycheck was also for $446 net pay. his parents know of a savings account that earns 4% compounded quarterly.
a. use the compounding interest rate formula to identify who will have more money after two years (assuming no additional deposits or withdrawals are made)
b. use the Desmos graphing calculator to graph Brooklyn's equation and Matthew’s equation on the same graph. identify the points of intersection and interpret the results.
WHAT MISTAKES DID THE STUDENTS MAKE??
After two years, Brooklyn will have more money in her savings account than Matthew.
Brooklyn's savings account grows at a slower rate than Matthew's initially but eventually catches up and surpasses Matthew's account due to the higher interest rate and monthly compounding.
a.
[tex]A = P(1 + r/n)^{nt}[/tex]
where A is the final amount, P is the initial principal (or net pay), r is the interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.
For Brooklyn saving account,
P = $625, r = 0.025, n = 12 (monthly compounding), and t = 2.
A = $625(1 + 0.025/12)^(12*2) = $686.71
For Matthew saving account,
P = $446, r = 0.04, n = 4 (quarterly compounding), and t = 2.
A = $446(1 + 0.04/4)^(4*2) = $506.84
b.
To graph Brooklyn's equation and Matthew's equation on the same graph, we can use the following equations:
Brooklyn's equation: A = 625(1 + 0.025/12)^(12t)
Matthew's equation: A = 446(1 + 0.04/4)^(4t)
Now,
The resulting graph will show the growth of each saving account over time.
The points of intersection on the graph represent the times when the two savings accounts have the same amount of money.
From the graph, we can see that the two accounts intersect at around 11 months and 23 months.
We can say that Brooklyn's savings account grows at a slower rate than Matthew's initially, but eventually catches up and surpasses Matthew's account due to the higher interest rate and monthly compounding.
Thus,
After two years, Brooklyn will have more money in her savings account than Matthew.
Brooklyn's savings account grows at a slower rate than Matthew's initially but eventually catches up and surpasses Matthew's account due to the higher interest rate and monthly compounding.

A geography teacher assigns each student to write a report about one of the first 13 colonies. Students select the name of a colony by "blindly" drawing a colony's name from a bag. Once a colony has been drawn, it is not replaced.
What is the probability that the first student selects Pennsylvania and the second student selects Virginia? Round your answer to the nearest hundredth of a percent.
The probability that the first student selects Pennsylvania and the second student selects Virginia to the nearest hundredth of a percent is 0.64%.
Probability problemThe probability that the first student selects Pennsylvania is 1/13. Once Pennsylvania has been drawn, there are only 12 colonies left in the bag, so the probability that the second student selects Virginia is 1/12.
To find the probability that both events occur, we multiply the probabilities:
(1/13) x (1/12) = 1/156
To express this probability as a percentage, we multiply by 100:
(1/156) x 100 ≈ 0.64%

use the equation 1/5 +s =32/40
The required solution to the equation 1/5 + s = 32/40 is s = 3/5.
To solve the equation 1/5 + s = 32/40 for s, we can begin by subtracting 1/5 from both sides to isolate s:
1/5 + s = 32/40
s = 32/40 - 1/5
We need a common denominator to combine the fractions on the right side of the equation. The least common multiple of 5 and 40 is 40, so we can convert both fractions to have a denominator of 40:
s = (32/40) - (8/40)
s = 24/40
Simplifying the fraction 24/40 by dividing both the numerator and denominator by their greatest common factor, which is 8, we get:
s = 3/5
Therefore, the solution to the equation 1/5 + s = 32/40 is s = 3/5.

An axon is a long, tubelike structure that extends from a neuron's cell body.
It is a specialized fiber that carries electrical impulses, known as action potentials, away from the cell body and towards the axon terminals.
Axons are covered by a fatty substance called myelin, which insulates and protects the axon and helps to speed up the transmission of signals.
At the end of the axon, there are small branches called axon terminals, which release chemicals called neurotransmitters into the synapse, the small gap between the axon terminals and the dendrites of the next neuron in the circuit.
This allows the electrical signal to be converted into a chemical signal and transmitted to the next neuron, continuing the chain of communication in the nervous system.

You deposit $500 in an account that earns simple interest at an annual rate of 4%. How much money is in the account after 6 years?
Answer:
The formula for simple interest is:
I = P * r * t
Where:
I = Interest earned
P = Principal amount (initial amount deposited)
r = Annual interest rate (as a decimal)
t = Time in years
Using the given values, we have:
P = $500
r = 0.04 (4% expressed as a decimal)
t = 6 years
I = P * r * t
I = $500 * 0.04 * 6
I = $120
So the interest earned after 6 years is $120. To find the total amount of money in the account, we add the interest to the principal:
Total = P + I
Total = $500 + $120
Total = $620
Therefore, there will be $620 in the account after 6 years.

m/2 - sqrt(5) + sqrt(5) = 3 + sqrt(5)
Simplifying:
m/2 = 3 + sqrt(5)
Next, we'll multiply both sides of the equation by 2:
