Answer: 3000 years
Step-by-step explanation:
Let y be the number of money and x be the number of years
So we have the equation
y= 6.5x + 10000
Now we put 29500 in the y
29500 = 6.5x + 10000
Subtracted 10000 from both sides
19500 = 6.5x
Divided both sides by 6.5
x = 3000 years

three calculus students entered a pizza parlor. they were quite hungry and ordered an entire pie, but instead of having the pizza maker cut the pie in the usual manner they asked her to slice the pie into three equal areas using only two parallel slices. where should these slices be made in order to accomplish this?
As per the Newton's method, the equal ration of the Pizza is 3: 2: 3
In math, Newton's method states that a technique for solving equations of the form f(x)=0 by successive approximation
Here we have given that three calculus students entered a pizza parlor. they were quite hungry and ordered an entire pie, instead of having the pizza maker cut the pie in the usual manner they asked her to slice the pie into three equal areas using only two parallel slices.
And we need to find these slices be made in order to accomplish this
Here let us assuming that the pizza has unit radius, and the area of the pizza is π and each piece has to have area π/3.
Therefore, the given details is enough to find the height of a circle segment such that its area is one third of the original circle,
As per the Newton's method, we get the value of h as,
=> h ≈ 0.735068 ≈ 4492/6111,
Therefore the three slices have widths approximately proportional to 3:2:3.

A group of nine people can now be seated in a row in 40320 different ways.
The two people who insist on sitting next to one other can be situated in one of two ways. The remaining seven people can be seated in seven different ways.
As a result, the total number of ways in which the nine persons can be seated in a row is 1 x 7! = 40320.
In this situation, the two people who dislike each other can be seated in
(7-1)! different ways.
The remaining seven people can be seated in seven different ways.
As a result, the total number of possible combinations for seating 9 individuals in a row is (7-1)! x 7! = 40320.

Tritan purchased a new car in 2000 for $22,800. The value of the car ha been depreciating exponentially at a constant rate then the Cost of the car in year 2016 will be $2811.
Cost price of the car = $22800
Value of the car has been depreciating exponentially, so the formula for value of the car after t years,
Here P(t) = Final value after t years
A = Cost price or initial value
r = rate of depreciation
t = duration in years
r = 100(1 - 0.87737)
r = 12.26%
Now cost of the car in year 2016 (After 16 years)
P(16) = 2810.99

[ select ] (b) from this available capacity, how many seats are protected for class 1, i.e., what is the protection level for class 1?
The function available capacity for the four classes is 40 seats each. The protection level for class 1 is 40 seats, meaning that 40 seats are protected for class 1. 40 + 40 + 40 + 40 = 160
The booking limits for the four fare classes in a flight are given as 40, 40, 40, and 40, respectively. This means that the available capacity for these four classes is 40 seats each. The protection level for class 1 is 40 seats, meaning that 40 seats are specifically reserved for passengers in class 1. This ensures that passengers in class 1 are guaranteed at least 40 seats on the flight. The protection level for the other classes is also 40 seats each, ensuring that at least 40 seats are available for each class. This allows airlines to ensure that all of their classes have sufficient seating capacity for their passengers. 40 + 40 + 40 + 40 = 160

Surface area implies the external surface that bounds a given shape. The surface area of the shape is 384 sq in.
The surface area of a shape is the external side of the shape that can be seen. Sometimes, a given shape may have different shapes that forms its surface area.
From the given question,
i. The area of triangular surface = 1/2 * base* height
= 1/2*12*8
= 48
Area of the triangular surface = 48 sq in.
ii. The area of its rectangular sides = length * width
= 9* 10
= 90
Area of its rectangular sides = 90 sq in.
iii. The area of its base = length * width
= 9 * 12
= 108
Area of its base = 108 sq in.
Therefore,
the surface area of the shape = (2*48) + (2*90) + 108

a fast-food restaurant runs a promotion in which certain food items come with game pieces. according to the restaurant, 1 in 4 game pieces is a winner. if jeff keeps playing until he wins a prize, what is the probability that he has to play the game exactly 5 times?
The probability that Jeff has to play the game exactly 5 times i.e he keeps playing until he wins prize is (0.25)⁵.
We have, a fast-food restaurant runs a promotion which consists some food items with games pieces. 1 in 4 game pieces is a winner. This means, probability of winning game or sucess (p) = 1/4 . Since number of trials is fixed, trials are independent and probability of success is constant in each trial, we can use Binomial distribution. The Binomial distribution probability formula is
P(X= x) = ⁿCₓ(p)ˣ(1-p)⁽ⁿ⁻ˣ⁾
where,n --> number of trials
p --> probability of success
x --> number of times for a specific outcome within n trials
ⁿCₓ --> number of combinations
we have calculate the probability that he has to play the game exactly 5 times, i.e
x = 5 . Jeff keeps playing until he wins and he wins when he play exactly 5 times so,n= 5
Now, plugging all known values in above formula we get,
P(X= 5) = ⁵C₅(0.25)⁵(1-0.25)⁰
=> P(X= 5) = ⁵C₅(0.25)⁵(0.75)⁰
=> P(X= 5) = 1× (0.25)⁵× 1 = (0.25)⁵

a deck of playing cards contains 52 cards, four of which are aces. what is the probability that the deal of a five-card hand provides a pair of aces?
The probability that the deal of a five-card hand provides a pair of aces is 0.0399
In this question, we have been given a deck of playing cards contains 52 cards, four of which are aces.
We need to find the probability that the deal of a five-card hand provides a pair of aces.
The sample space for given experiment is: choosing 52 cars choosing 5.
n(S) = 52C_5
We need to find the chance of getting a pair of aces, there are 4 aces in the pack on 2 of them.
So, n(A) = 4C_2
So that means there are 48 cards left which are not aces in the pack and want 2 of those.
So, the required probability is:
P(A) = (4C_2 * 48C_3) / 52C_5
P(A) = (6 * 17296) /2598960
P(A) = 103776 / 2598960
P(A) = 0.0399

What is probability?The area of mathematics known as probability is concerned with the outcomes of random events. Probability refers to a chance or potential for something to happen. It explains the likelihood that a specific event will take place.
We frequently say things like, "It will probably rain today," "He will probably pass the test, "There is very little chance of getting a storm tonight," and "Most likely the price of onions will increase once more." We substitute the word probability for all of the words chance, doubt, maybe, likely, etc. in these sentences.
In essence, probability is the ability to forecast an outcome based on the variety and quantity of potential outcomes or the analysis of historical data.
