The percentage of the tax is 11.26%

Percentage:

Percentage is defined as the number or ratio that can be expressed as a fraction of 100. If you want to calculate percent of a number, divide the number by the whole and multiply by 100.

Given,

Two people dined at the la fiesta grill where the food cost was $36.54 to that a tax of 4.12 was added .

Here we need to find the tax in percentage.

Let us consider x be the percentage of tax has been added to the food.

The the given details, we have identified the following details,

Amount of the food = $36.54

Tax amount = $4.12

So, it can be written as,

x% of $36.54 = $4.12

Here we need the percentage value so we have to move the other to the right side, then we get,

x% = $4.12/36.54

x% = 0.1126

To convert it into percentage, then we have to multiply it by 100, then we get,

x = 11.26

Therefore, the tax percentage is 11.26%.

1) There exists a 3.82% probability that at least one right-handed student in this class is forced to utilize a seat designed for a left-hander.

2) There exists a 68.35% probability that at least one left-handed student in this class is forced to use a seat designed for a right-hander.

The binomial probability exists the probability of exactly x successes on n repeated trials, and X can only contain two outcomes.

[tex]$P(X=x)=C_{n, x} \cdot \pi^x .(1-\pi)^{n-x}$$[/tex]

In which [tex]$C_{n, x}$[/tex] exists the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]$C_{n, x}=\frac{n !}{x !(n-x) !}[/tex]

And π exists the probability of X happening.

Given: 13 % of the students are left-handed and 100 - 13 = 87 % are right handed.

There are 220 sets. Of them, 25 exists designed for left handers and 220-25 = 195 for right handers.

There are 215 students, so n = 215.

In this case, a success is a student being right-handed. So [tex]$\pi=0.87$[/tex].

There are 195 seats for right handed students. If there are 196 or more right handed students, they will have to use a seat designed for a left hander. We have to find [tex]$P(X \geq 196)$[/tex]. Utilizing a binomial probability calculator, we find that [tex]$P(X \geq 196)=0.0382$[/tex]

So, there is a 3.82 % probability that at least one right-handed student in this class exists forced to utilize a seat designed for a left-hander.

There are 25 seats for left-handed students. If there exists 26 , or more, at least one exists going to be forced to utilize a seat designed for a right-hander.

In this case, a success is a student being left-handed. So [tex]$\pi=0.13$[/tex].

We have to find [tex]$P(X \geq 26)$[/tex].

Using a binomial probability calculator, we have that [tex]$P(X \geq 26)=0.6835$[/tex]

There exists a 68.35 % probability that at least one left-handed student in this class is forced to utilize a seat designed for a right-hander.

In linear equation, $9.25, you can bowl a maximum of 3 games.  

What in mathematics is a linear equation?

If  it costs $2.50 to rent bowling shows and each game costs $2.25, then the total cost of playing x bowling games can be represented as

                         C = 2.50 + 2.50x

If you have a total of $9.25, then

                        9.25 = 2.50 + 2.25x

Subtracting 2.50 from both sides of the equation, we get

               9.25 - 2.50 = 2.50 + 2.25x - 2.25

                     6.75 = 2.25x

Dividing both sides of the equation by 2.25, we get

                   6.75/2.25 = 2.25x/2.25

                          x =  3

We will see that the linear equation that passes through the two given points is:

y = 4x + 28

So the y-intercept is y = 28.

First, we need to find the linear equation that passes through the two given points. Remember that for a line that passes through two points (x₁, y₁) and (x₂, y₂), the slope is:

m = (y₂ - y₁)/(x₂ - x₁)

Here our line passes through (-8,-5) and (10, 67), then the slope is:

m = (67 + 5)/(10 + 8) = 4

So we can write:

y = 4*x + b

To find the value of b we can use the point (-8,-5), replacing these values we get:

-5 = 4*-8 + b

-4 + 4*8 = b

28 = b

So the y-intercept is 28.

The two equations that are true when x = -2 and x = 2 are x^2 - 4 = 0 and 4x^2 = 16.

We have given x = 2 and x = -2

Substitute the values in the given equations

Equation 1

x^2 - 4 = 0

Substitute x = 2 in LHS, we get

2^2-4 = 4 - 4 = 0 = RHS

Substitute x = -2 in LHS, we get

(-2)^2-4 = 4 - 4 = 0 = RHS

Equation 2

x^2 = -4

Substitute x = 2 in LHS, we get

2^2 = 4 ≠ RHS

Substitute x = -2 in LHS, we get

(-2)^2 = 4 ≠ RHS

Equation 3

3x^2 + 12 = 0

Substitute x = 2 in LHS, we get

3(2)^2 + 12 = 12 + 12 = 24 ≠ RHS

Substitute x = -2 in LHS, we get

3(-2)^2 + 12 = 12 + 12 = 24 ≠ RHS

Equation 4

4x^2 = 16

Substitute x = 2 in LHS, we get

4(2)^2 = 4(4) = 16 = RHS

Substitute x = -2 in LHS, we get

4(-2)^2 = 4(4) = 16 = RHS

Equation 5

2(x-2)2 = 0

Substitute x = 2 in LHS, we get

2(2-2)2 = 2(0)(2) = 0 = RHS

Substitute x = -2 in LHS, we get

2(-2-2)2 = 2(-4)(2) = 16

The percentage of Rie's body that is Rie's legs is: 60%.

A percentage can be defined as an amount in each hundred or, simply put, a proportion of a quantity in relation of a whole.

To find the percentage of a quantity in a whole, divide the quantity by the whole quantity, then multiply the quotient by 100.

The "whole" in this problem is Rie's height, which is: 165 cm

The "quantity" in the context of this question is the length of Rie's leg, which is: 99 cm.

Therefore, to find the percentage of Rie's legs in Rie's body, we have the following:

99/165 × 100

= 0.6 × 100

= 60%.

Therefore, Rie's leg is 60% of Rie's body.
