what is the difference between theoretical and experimental probability

After calculating the discount and subtracting it from the original price, Eric's bike cost $135.60, which is $14.35 less than Kurt's bike that cost $149.95.

To determine how much less Eric paid for his bike compared to Kurt's bike, we need to calculate the discount Eric received and subtract it from the original price of his bike. Then, we'll compare it to the price Kurt paid for his bike.

First, we calculate Eric's discount by multiplying the original price of the bike, $169.50, by 1/5 (which represents the 20% discount):

$169.50 times  15= $33.90.

Now, subtract this discount from the original price to find out how much Eric paid for the bike:

$169.50 - $33.90 = $135.60.

Finally, to find out how much less Eric's bike cost than Kurt's, we subtract the price Eric paid from the price Kurt paid:

$149.95 - $135.60 = $14.35.

Eric's bike cost $14.35 less than Kurt's.

The vertex form of the equation of a parabola with a vertex at (0,0) and passing through the point (1,2) is [tex]y=2x^2.[/tex]

The vertex form of a parabola is given by: [tex]y = a(x - h)^2 + k[/tex] where (h, k) is the vertex of the parabola.

In this case, the vertex is (0, 0), so h = 0 and k = 0.

Therefore, the equation becomes: [tex]y = a(x - 0)^2 + 0.[/tex] Simplifying further, the equation becomes: [tex]y = ax^2[/tex].

Now, we need to find the value of 'a.' To do this, we can use the given point (1, 2). Substitute these values into the equation:

[tex]2 = a(1)^2[/tex].

Therefore, 'a' is 2. So, the final equation in vertex form is: [tex]y = 2x^2.[/tex]

So, the correct answer is A. [tex]Y = 2x^2.[/tex]

The solution is, There are 198 calories in a 22-oz iced tea.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

given that,

a 15-oz iced tea at a certain restaurant had 135 calories.

now we have to find that, How many calories are there in a 22-oz iced tea.

i.e. we have

15/135 = 22/?

let, x calories are there in a 22-oz iced tea.

now, 15/135 = 22/x

or, x = 22 x 135 / 15

we have,

22 x 135 = 2970

2970/15 = 198

so, x = 198

There are 198 calories in a 22-oz iced tea.

Hence, The solution is, There are 198 calories in a 22-oz iced tea.

A clockmaker is the answer

There are 54 people at the party.

18 people are wearing red which means that 36 people are not wearing red

54 - 18 = 36

The fraction [tex]\frac{36}{54}[/tex] represents the 36 people at the party that are wearing no red. We can find what percent of the people at the party are not wearing red by turning [tex]\frac{36}{54}[/tex] into a percent.

[tex]\frac{36}{54}[/tex] can be reduced to [tex]\frac{2}{3}[/tex]  by dividing both the numerator and denominator by the greatest common factor of 36 and 54.

2 ÷ 3 = 0.667

0.667 × 100 = 66.67%

Therefore, 66.67% of the people at the party are not wearing red

The inverse of the relation y=6x-3 is y = (x + 3) / 6.

To find an equation for the inverse of the relation y=6x-3, we need to follow a series of steps which involves swapping the variables, and then solving for the new y.

Start with the initial equation: y = 6x - 3.

Swap the variables x and y: x = 6y - 3.

Solve for y to find the inverse relation: Add 3 to both sides to get x + 3 = 6y, then divide both sides by 6 to isolate y, resulting in y = (x + 3) / 6.

Final answer:

The triangle with angles of 120 degrees, 35 degrees, and 25 degrees is classified as an obtuse scalene triangle because it has one angle greater than 90 degrees and all angles of different measures.

Explanation:

To classify the triangle with angles of 120 degrees, 35 degrees, and 25 degrees, we first confirm that the sum of its angles is 180 degrees, which is true for any plane triangle. Given this sum, we can classify the triangle based on its angles and sides.

A triangle with one angle greater than 90 degrees is called an obtuse triangle, as it has an obtuse angle (greater than 90 degrees). Since this triangle has a 120-degree angle, it fits that definition. Furthermore, because all the angles are different, we can classify it as a scalene triangle, meaning all sides have different lengths. Therefore, the correct classification for this triangle is an obtuse scalene triangle.

The first line is the line of best fit for this given disperse plot.

"A disperse plot is a kind of plot or numerical graph involving Cartesian directions to show values for regularly two factors for a bunch of information.

On the off chance that the focuses are coded, one extra factor can be shown."

For a particular scatter plot, four different lines are drawn here.

We know, a line drawn on a disperse plot fits it the best is the line that is nearer to a large portion of the places.

The calculated quotient of the expression (14x³ - 21x² + 28x) ÷ 7x is 2x² - 3x + 4

How to evaluate the quotient expression

From the question, we have the following parameters that can be used in our computation:

(14x³ - 21x² + 28x) ÷ 7x

Factor out x in the numerator

So, we have

(14x³ - 21x² + 28x) ÷ 7x = x(14x² - 21x + 28) ÷ 7x

Evaluate the quotient

(14x³ - 21x² + 28x) ÷ 7x = (14x² - 21x + 28) ÷ 7

Divide through by 7

(14x³ - 21x² + 28x) ÷ 7x = 2x² - 3x + 4

Hence, the quotient of the expression is 2x² - 3x + 4

The solution is 17 chairs

The number of chairs placed is 17 and the inequality equation is 2x < 35 , where x is the number of chairs

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the number of chairs be represented as x

Now , the inequality equation will be

Each chair installed in the new chapel requires 24 inches of clearance

So , 24 inches = 2 feet

And , each row cannot be greater than 35 feet

So , the number of 2 feet chairs = 2x

And , 2x cannot be greater than 35 feet

Substituting the values in the equation , we get

2x < 35   be equation (1)

Divide both sides of the equation by 2 , we get

x < 17.5

x < 17 chairs

Therefore , the value of x is 17 chairs

Hence , the number of chairs is 17 chairs

-mustard

Solution:

There are five toppings available and the five toppings are lettuce, tomato, bacon, cheese, mustard.

We need to make 2 topping sandwiches.

So, we can select any 2 toppings from the available 5 toppings

So, we must use combination here

So, the number of two topping sandwiches is 5 combination 2

Or, Number of 2 topping sandwiches= 5 C 2

The formula is, n C r =[tex]\frac{n!}{(n-r)!r!}[/tex]
