The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Original price = $179.30

The selling price = $154.15

The percent markdown.

= (179.30 - 154.15) / 179.30 x 100

What is a triangle?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

Given that the length of two sides of a triangle are 20 and 15.

Triangle inequality theorem:

The sum of two sides of a triangle is always greater than the third side.

The of two sides of the triangle is (20 + 15) = 35.

According to triangle inequality theorem,

The third side of the triangle must be less than 35.

Assume that the length of the third side is x.

Therefore, x ≤  35.

Step-by-step explanation:

The middle number on the 50th row is 891.5.

The nth row is 18n - 17.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

We see that there are 18 numbers in each row.

The numbers are consecutive natural numbers.

Now,

We can see that,

The first number of each row is 1.

The first number of the second row is 19.

The first number of the third row is 37.

The first number in each row can form a series.

1, 19, 37,....

This series is an arithmetic sequence.

First term = 1

Common difference = 18

The nth term is a + (n - 1)d.

50th term.

= 1 + (50 - 1)18

= 1 + 49 x 18

= 1 + 882

= 883

This means,

The 50th row will have the following series.

883, 884, 885, 886, 887, 888, 889, 890, 891, 892, 893, 894, 895, 896, 897, 898, 899, 900.

The middle number is the midpoint of 891 and 892.

= 891.5

The nth row.

= 1 + (n - 1)18

= 1 + 18n - 18

= 18n - 17

Thus,

The middle number on the 50th row is 891.5.

Step-by-step explanation:

the area between first two curves is 10.67-unit, 2nd two curves is 8-unit, 3rd two curves is 7.5 unit, and the last two curves is

area bounded by two curves means the curves have intersected each other and we can determine the point of intersection of them. In the next we apply the integration with limit formula for the equation of curves in where the point of intersection acts as the upper and lower limit.

while determining area we get either negative value or positive value depending on the position of curve in the xy  coordinate but in real life the value of area is written as a positive number.

1. the curve y=x² and y=4x

let the two curves intersects each other so x²- 4x= 0

                                                    x=0, 4

                                   for this value of x, we determine the values of y

                                  y= 0, 16

  now we determine the area between two curves by using the formula, ∫x²dx-∫4xdx

            ∫₀⁴(x²-4x) dx

               [1/3×x³-³4/2×x²]₀⁴

   area = -10.67

2. the curves y=x+1 and y=5 is intersected as we need to calculate the area bounded by them, 5=x+1 and x=4

for x=4, we get y= 5

now the area will be ∫₀⁴(x+1-5)dx

                                     [1/2x²- 4x] ⁴

                                 area= -8 unit

3. in case of 3rd two curves, x=y² and x-y=2

                                   y²-y=2, hence y= -1, 2

   the x values are x= 1, 4

the area bunded by them is ∫₋²₁{y²-(y-2)}dy

                                [1/3y³-1/2y²+2y]₋²₁

                                area =7.5 unit

4. from the last two curves y=4+x, y²= 2-x

  hence, the area calculated are 10.67-unit, 8 unit and 7.5 unit respectively.

You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.

Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

In graphical form, the normal distribution appears as a "bell curve".

The normal distribution is the proper term for a probability bell curve.

In a normal distribution the mean is zero and the standard deviation is1. It has zero skew and a kurtosis of 3.

Normal distributions are symmetrical, but not all symmetrical distributions are normal.

The t-distribution describes the standardized distances of sample means to the population mean when the population standard deviation is not known, and the observations come from a normally distributed population.

On solving the given question, by the equation, A riding 48 mi at 8 mph takes 6 hours, which indeed is 3 hours longer .A riding 48 mi at 8 mph takes 6 hours, which indeed is 3 hours longer.

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal."

J can ride his bike 8 mph faster than A can ride. It takes A 3 hours longer than J to ride 48 miles. How fast can J ride?

Let r = rate that J rides, in miles per hour.

Then rate that A rides is (r – 8).

distance = rate * time

time = distance/rate

Time taken by J to ride 48 miles = 48/r.

Time taken by A to ride 48 miles = 48/(r – 8).

But A's time is 3 hours more than J's time.

48/(r – 8) = 3 + 48/r

Solve that for r.

48/(r – 8) = 3r/r + 48/r

48/(r – 8) = (3r + 48)/r

Multiply both sides by (r – 8)r.

[tex]48(r) = (3r + 48)(r - 8)\\ 48r = 3r2 -24r + 48r -384\\ 0 = 3r2 - 24r -384\\ 0 = r2 -8r - 128\\ 0 = (r -16)(r + 8)[/tex]

So r = 16 mph or r = –8 mph.

J riding 48 mi at 16 mph takes 3 hours.

A riding 48 mi at 8 mph takes 6 hours, which indeed is 3 hours longer.

Answer: \boxed{0.49}.

The compound inequality is -4 < X < 6.

Let X represents the numbers between 4 and 6

X is between 4 and 6. This means that 4 and 6 are not included in the series of numbers. Thus, they are the boundaries of the series of numbers.

The number between 4 and 6 is 5.

To find the compound inequality, we look at the series of numbers. Here, we notice that the number 5 is greater than 4  (the number is greater than 4 because it lies on the right-hand side of 4 on the number line) and the number 5 is smaller than 6 (the number is smaller than 6 because it lies on the left-hand side of 6 on the number line).

Thus, the compound inequality is -4 < X < 6.

On solving the provided question we can say that  the equation of the line will be  y+11 = 0.

The slope of a line is how steeply it slopes from left to right. The slope of a line is determined by dividing its rise (vertical change) by its slope, which is its horizontal change. Regardless of whatever two locations on the line you pick, the slope of the line is always constant (it never changes).

To find the coordinates of two points on the line, choose two. Find the difference between these two locations' y-coordinates (gradients). Find the difference between these two places' x coordinates (runs). Divide the change in the y coordinate by the difference in the x coordinate (slope/history or slope).
