The cumulative percent frequency for students working less than 20 hours per week is 25%.
In statistics, the frequency of the first-class interval is added to the frequency of the second class, and this sum is added to the third class and so on then, frequencies that are obtained this way are known as cumulative frequency (c.f.). A table that displays the cumulative frequencies that are distributed over various classes is called a cumulative frequency distribution or cumulative frequency table. There are two types of cumulative frequency - lesser than type and greater than type. Cumulative frequency is used to know the number of observations that lie above (or below) a particular frequency in a given data set. Cumulative frequency is the total frequencies showcased in the form of a table distributed in class intervals. There are two types of cumulative frequency i.e. lesser than and greater than, let us learn more about both types.
The number of hours frequency is given as follows:
Number of hours Frequency Cumulative frequency
0 - 9 20 20
10 - 19 80 100
20 - 29 200 300
30 - 39 100 400
So, the cumulative percent frequency for students working less than 20 hours per week is
= (No. of students working less than 20 hours/ total number of students)* 100
= (100/400)*100
= 25%
Thus, the cumulative percent frequency for students working less than 20 hours per week is 25%.

A building is in the from of a cylinder of radius 7 m and height 6 m sumounted by a cone of same radius and of siant height 14 m calculate the outer surface area of the building
The outer surface area of the building is 356 m².
What distinguishes surface area from outer surface area?
The total area of a three-dimensional object's base, top, and any lateral or exterior surfaces is measured as surface area. A cone, cube, cuboid, or cylinder's surface area is the area it covers on the outside. The formula for a cube's total surface area is 6 (side)2. A cuboid's lateral surface area is equal to 2(length + width) height. Similar to this, a cube with side "a" has lateral surface area equal to 4 (side)2.
Given that,
radius of building = 7m
and its saint height = 14m
Outer surface area = πrl + 2πrh
= πr( L + 2h )
= 22/7 × 7 ( 14 + (2×6))
= 22 × (14 + 12)
= 22 × 26
= 356 m².

It costs $15 to rent a popcorn machine and it costs $25 to rent a cotton candy maker. The cost of additional supplies for the popcorn is $0.05 per bag. The additional cost for the cotton candy is $0.10 per stick. Team A will sell the bags of popcorn for $0.50 each. Team B will sell the cotton candy for $0.75 per stick.
What is the least number of items Team A will need to sell to avoid losing money?
Team A will need to sell at least 256 bags of popcorn to avoid losing money.
What is a linear equation?When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."
There are both one-variable and two-variable linear equations.
Given total amount to be raised by each team is $100,
Team A wants to sell popcorn,
rent of popcorn machine = $15
total cost to be earned for team B = $100 + $15 = $115
let the number of candies sold be x
cost used in popcorn bag = $0.05 per stick
cost used in x popcorn bag = $0.05x
the selling price of each popcorn bag = $0.50
the selling price of x popcorn bag = $0.50x
total gain = $0.50x - $0.05x
total gain = $0.45x
minimum number of popcorn bags to be sold for no loss
$0.45x = $115
x = 115/0.45
x = 255.55
x = 256
Hence for no loss, at least 256 popcorn bags are to be sold.

Answer:
h = -12
Step-by-step explanation:
Here's a step-by-step explanation to solve the equation:
h/6 - 1 = -3
Start by adding 1 to both sides of the equation to isolate h/6 on one side.
h/6 - 1 + 1 = -3 + 1
h/6 = -2
Next, multiply both sides of the equation by 6 to isolate h on one side.
6 * (h/6) = 6 * (-2)
h = -12
So the solution is: h = -12.

find a parametrization for the line in which the planes intersect:
3x-6y-2z=3 and 2x y-2z = 2
The parametrization of the line of intersection of the two planes is <12, -6, 12>
A parametrization is a way of representing a line or a curve using a set of parameters.
First, we can find the normal vectors of the two planes.
For the first plane, the normal vector is given by <3, -6, -2>, and for the second plane, the normal vector is given by <2, 1, -2>.
The line of intersection will be parallel to the cross product of these two normal vectors, which is <12, -6, 12>.
Plugging in the values from the first plane, we get:
3x - 6y - 2z = 3
3x = 6y + 2z + 3
x = 2y + z + 1
Now that we have a point on the line, we can use this to parametrize the line.
We can use the direction vector <12, -6, 12> and the point <1, 0, 0> to find the parametrization of the line:

You invest a certain amount of money at an interest rate of 6% for 4 years, and earn $168 in interest, how much did you originally invest?
Answer:
Amount originally invested = $700
Step-by-step explanation:
[This answer assumes that the interest is simple interest.]
We are told that upon investing a certain amount of money for 4 years at a rate of 6%, we get $168 in interest. We are then asked to calculate the amount originally invested.
To solve this problem, we have to use the formula for simple interest:
[tex]\boxed{I = PRT}[/tex],
where:
• I ⇒ interest = $168
• P ⇒ principal (original) amount = $?
• R ⇒ interest rate = 6% = 0.06
• T ⇒ time for which the money is invested = 4 years.
Using the above formula and rearranging it to make P the subject of the equation, we can calculate the principal amount:
[tex]I = PRT[/tex]
⇒ [tex]P = \frac {I}{RT}[/tex]
⇒ [tex]P = \frac{168}{0.06 \times 4}[/tex]
⇒ P = 700
Therefore, the amount originally invested was $700.

Jessie and Bob's balloon payment will be $529,229.56.
A balloon mortgage is a type of mortgage in which the borrower makes smaller monthly payments over the term of the loan, with a large balloon payment due at the end.
To calculate the balloon payment, we need to know the amount of the loan, the interest rate, and the term of the loan.
Given that Jessie and Bob are financing $425,500 to purchase a house, the interest rate is 6.55%, and the term of the loan is 30/8 (or 3.75) years, we can use the below formula to calculate the balloon payment:
Balloon payment = Loan amount * (1 + Interest rate * Loan term)
Balloon payment = $425,500 * (1 + 6.55% * 3.75)
Balloon payment = $425,500 * 1.249625
Balloon payment = $529,229.56

A linear function, m(t) = 2500 + 40t, may be used to describe the savings account balance, where t is the number of years that have elapsed. The $2500 starting sum is taken into consideration, and for each year that has gone, an additional $40 is added. This gain might be compared to an annual interest rate or investment growth.
Then, B(t) = m(t) + 500 may be used to represent the combined balance of both accounts. This function transfers the fixed balance of $500 in the checking account to the savings account balance, m(t). We may simply fill in the value of t to get the total financial condition at any given year by merging both accounts.
Making decisions about spending, saving, and investing may be done using this kind of depiction, which is helpful for tracking financial development over time. It may also be used to define financial objectives and monitor progress toward them. One may change their spending patterns and investing strategies to get to the desired financial position by keeping an eye on the trend in the growth of the overall balance.

a.) M(t) = 2500 + 40t is a representation of the savings account amount after t years. The $2500 starting sum is added to a $40 annual increase using this function.
b.) The total balance of the two accounts at the end of t years may be written as B(t) = m(t) + 500. In this function, the constant $500 checking account amount is added to the savings account balance, m(t).
Investment
Allocating money or capital to purchase securities or other assets in the hopes of turning a profit or seeing their value increase is known as investing.
Stocks, bonds, mutual funds, and other forms of real estate and commodities are just a few examples of the many shapes and sizes that investments can take. As each type of investment carries specific risks and potential rewards, selecting the right balance of investments is essential to a sensible investing strategy.
Most investments are made with the hope of accumulating money over time. By investing, people can increase their wealth and secure their long-term financial well-being or save for future expenses like retirement. Investing can also serve as an inflation hedge because it frequently outperforms inflation rates in terms of returns. The kind of assets a person selects and the level of risk they are willing to accept are determined by their investment goals and time horizon.

A 16 foot ladder leans against a brick wall. The ladder reaches a height of 8 feet on the wall. The ladder makes a ___° with the wall.
Solve for x
The ladder makes a 60° angle with the wall.
What makes a right triangle?
A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle.
In this case, we can draw a diagram. What we get is a right triangle with one leg as 8 and the hypotenuse as 16.
This is a 30-60-90 triangle (because the leg is half the hypotenuse).
They want the angle the ladder makes with the wall, so the angle between hypotenuse and leg, which is 60 degrees.
cos (angle) = adjacent / hypotenuse = 8/16
arcos(8/16) = 60°
x = 60°
Hence, The ladder makes a 60° angle with the wall.

The ladder makes an angle of 60° with the wall . The angle made between the ladder and the wall is 60°.
Here, these values are given,
Height of ladder = 16 foot
Height of wall = 8 foot
So, We have to find the angle made between the ladder and the brick wall.
Let, the angle made between the ladder and the wall be x °.
So, According to question ,
We use trigonometry for finding the value of angle between the ladder and the wall.
cos∅ °= base/height ( b/h)
Because, base = height of wall and hypotenuse = height of ladder.
Then, cos x° = 1/2
cos x ° = cos 60°
So, x° = 60°

What is value and what is position in for loop?
The value represents the content of the current iteration, while the position represents the index or iteration number of that value.
In a for loop, the "value" refers to the current iteration value assigned to a variable, while the "position" refers to the iteration number or index.
For example, in a for loop that iterates over a list of numbers, the value could be each individual number in the list, while the position could be the index of that number in the list.
For example, consider the following code:
numbers = [1, 2, 3, 4, 5]
for i, value in enumerate(numbers):
print("Position:", i, "Value:", value)
The output of this code would be:
Position: 0 Value: 1
Position: 1 Value: 2
Position: 2 Value: 3
Position: 3 Value: 4
Position: 4 Value: 5
Here, i represents the position, starting from 0 and increasing by 1 for each iteration, and value represents the value assigned to each number in the numbers list.
