Due to the fact that many people only call their doctors when they are ill once or twice a year, the data is skewed toward the lower levels.

A histogram is a bar graph-like data visualization that groups various class levels into columns along the horizontal x-axis. Each column's data count or percentage of occurrences are shown on the vertical y-axis. Data distribution patterns can be seen visually using columns.

A common tool for graphing is the histogram. It is employed to summarise continuous or discrete data that is measured on an interval scale. It is frequently used to provide a convenient manner of illustration for the main characteristics of the data distribution.

Histograms show numerical or quantitative data, whereas bar charts show categorical factors. The numerical data in a histogram will typically be continuous in most cases (having infinite values).

Therefore, the correct answer is option b) The data is skewed to the lower values because many patients only call the doctor once or twice a year when they are sick.

Market price of goods is 3942.86 Rs.

The price at which a goods, assets, instruments or raw materials are bought and sold at a wholesale market.

let, market price of Nepali goods = X

after allowing discount and vat the price of goods = 4140 Rs

discount = 10 %

the amount of discount = X 10/ 100

Vat added = 15%

the amount of vat added = X 15/ 100

Now, discount is subtracted from market price and vat is added to it.

The equation will be

X - X10/100 + X15/100 = 4140 Rs

X = 3942.86 Rs

The value of (fxg)(-3) if f(x)=5x-1 and g(x) =2x^2+1 will be 94.

A function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. Let A & B be any two non-empty sets; mapping from A to B will be a function only when every element in set A has one end, only one image in set B. It is a relation “f” in which each element of set “A” is mapped with only one element belonging to set “B”. Also in a function, there can’t be two pairs with the same first element.

f(x)=5x-1

g(x) =2x^2+1

fxg = 5(2x^2+1) - 1

fxg = 10x^2 + 5 - 1

fxg = 10x^2 + 4

fxg(-3) = 10(-3)^2 + 4

fxg(-3) = 10(9) + 4

fxg(-3) = 90 + 4

The correct answer is Michelle makes a quarter turn to her right and Rebecca makes a three eight turn to her left.

Speed is the rate of change of position. It is the physical quantity that measures how quickly an object moves from one place to another. It is measured in units such as meters per second, kilometers per hour, or miles per hour. Speed is related to velocity, which is the measurement of how quickly an object moves in a specific direction. Speed is an important concept in physics and is necessary for understanding how the universe works.

Michelle makes a quarter turn to her right and Rebecca makes a three eight turn to her left. By making these turns, they will both end up facing north. A quarter turn to the right is the same as a three eight turn to the left. This is because a full turn is 360 degrees, so a quarter turn is 90 degrees and a three eight turn is also 90 degrees.

Answer:

the equation for the ellipse that describes the arch is:

(x^2/20^2) + (y^2/6^2) = 1

Step-by-step explanation:

An ellipse can be represented by the equation (x^2/a^2) + (y^2/b^2) = 1, where a and b are the lengths of the semi-major and semi-minor axes of the ellipse, respectively. In this case, the x-axis coincides with the water level and the y-axis passes through the center of the arch, so the center of the ellipse is at the point (0, 6).

For the arch in question, the semi-major axis is 20 meters (since the arch spans a river 20 meters wide) and the semi-minor axis is 6 meters (since the center of the arch is 6 meters above the center of the river).

So the equation for the ellipse that describes the arch is:

(x^2/20^2) + (y^2/6^2) = 1

The monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.

What is simple interest?

Simple interest is based on the principal amount of a loan or the first deposit in a savings account. Simple interest doesn't compound, which means a creditor will only pay interest on the principal amount and a borrower would never have to pay more interest on the previously accumulated interest.

The simple interest earned can be calculated by using this formula

A = P(1 + rt)

Where,

A is the future value.

P is the principal value.

r is the interest rate.

t is the time.

Now Substituting the values into the formula, we have,

A = 16,000[1 + (0.08 × 3)]

A = 16,000[1 + 0.24]

A = 16,000× 1.24

Future value, A = $19,840.

Following that, we will compute the monthly payment over a 36-month period as follows:

Monthly payment = Future value/Time

Monthly payment = 19,840/36

Monthly payment = $551.11

Similarly, we will compute the credit card's compound interest:

A = 16000[1 + (0.15/12)]⁽¹² ˣ ⁷⁾

A = 16000[1 + 0.025]⁸⁴

A = 16000× 1.025⁸⁴

A = 9000 × 3.49258954

Future value, A = $45425.80

Following that, we will compute the monthly payment over an 84-month period as follows;

Monthly payment = Future value/Time

Monthly payment = 45425.80/84

Monthly payment = $540.78.

Hence, the monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.

Using equation, the number of large drinks is 126.

A drink stand is selling small drinks for $2 each and large drinks for $4 each. One day, a total of 150 drinks were sold for $552.

The number of large drinks sold can be calculated as follows:

Using equation,

let

x = number of small drinks

y = number of large drinks

Hence,

2x  + 4y = 552

x + y = 150

multiply equation(ii) by 2

2x  + 4y = 552

2x + 2y = 300

subtract equation(ii) from equation(i)

2y = 252

divide both sides by 2

y = 252 / 2

y = 126

The final result of  algebra is: (6x^3 - x^2 - 14x + 5) : (2x - 1) = 3x^2 - x - 7 + 5/(2x-1)This is the simplified form of the given expression.

Simplification is the process of making an expression or equation simpler and easier to understand or work with. In mathematics, simplification often involves combining like terms, removing unnecessary operations, or reducing the number of terms in an expression. The goal of simplification is to obtain an equivalent expression that is clearer, more manageable, and easier to interpret.

Here ,

is the step by step process:

(6x ^ 3 - x ^ 2 - 14x + 5):(2x - 1)

Step 1: Divide 6x^3 by 2x and write the quotient 3x^2.

Step 2: Multiply the denominator (2x - 1) by the quotient (3x^2)

Step 3: Subtract the result from the numerator and bring down the next term of the numerator ( x^2)

Step 4: Repeat the process by dividing the x^2 by 2x and write the quotient -x.

Step 5: Multiply the denominator (2x - 1) by the quotient (-x)

Step 6: Subtract the result from the numerator and bring down the next term of the numerator ( -14x)

Step 7: Repeat the process by dividing the -14x by 2x and write the quotient -7

Step 8: Multiply the denominator (2x - 1) by the quotient (-7)

Step 9: Subtract the result from the numerator and bring down the next term of the numerator (5)

Step 10: We can see that the degree of the remainder is less than the degree of the denominator so we can write the remainder as 5/(2x-1)

So the final result is:(6x^3 - x^2 - 14x + 5) : (2x - 1) = 3x^2 - x - 7 + 5/(2x-1)

By ranking the wages of a group of employees in descending order, you may determine the median base salary by finding the wage that is in the Middle of the distribution . 50 percent of earnings fall below the median, while 50 percent of salaries rise above the median.

The average of a set of numbers is known as the mean. If there are five salaries involved and the mean is $360, the total can be calculated by

Average = Total / number

Total = (Average)(Number)

Total = $360 * 5 = $1800
