Answer:

a. the percentage of the students who not drive a car is 44%

b. Number of students in 1 car

c. 1 = 3 i think

Step-by-step explanation:

11 / (14 + 11)

11/25

average is 2 i think

you can change the denominator to 100 by multiply 4, dont forget to do the same to the top

44/100

the percentage of the students who not drive a car is 44%

mean is average. to find the mean add all the given then divide by how many

sooo i think since it said "number of students in each car"

1 + 2 + 3 / 3

6 / 3

2 i think?

The solutions to the equations is

The percentage of students who do not travel by car is given by the equation A = 44 %

The mean number of students in each car is 2 students and the missing frequency is 3 cars

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The total number of students in the school = 25 students

The number of students who travel by car = 14 students

The number of students who do not travel by car = 11 students

So , the percentage of students who do not travel by car = ( number of students who do not travel by car x total number of students in the school ) x 100

Substituting the values in the equation , we get

The percentage of students who do not travel by car A = ( 11/25 ) x 100

On simplifying the equation , we get

The percentage of students who do not travel by car A = 0.44 x 100

The percentage of students who do not travel by car A = 44 %

And , the missing frequency is f = 3 cars

The total number of students in one car = 1 + 2 + 3 = 6 students

So , the mean number of students in each car = 6/3 = 2 students

Hence , the equations are solved

Answer:

slope is 5, y intercept is -7

Step-by-step explanation:

In the form y=mx+c, m is the slope and c is the y-intercept.

Rearrange the formula to fit this form:

5x-y=7

-y=7-5x

y=5x-7

∴m(slope)=5

∴c(y-intercept)=-7

There are 40128 peoples in the parade route by proportion.

According to the given question.

You can fit 19 people in a 5ft x 5ft square.

Here we need to find the number of peoples in the 10ft x 1 mile parade.

Since, we have to convert miles into feet then,

1 mile = 5280 feet

We know that the parade route is in the form of rectangle.

Also, the process of proportion reasoning involves understanding the multiplicative relationships between rational quantities.

Now we will find the number of peoples by proportions,

Let us consider the number of people in the rectangle as x.

Therefore,

19/25  = x/5280

⇒ (19/25)(5280) = x

⇒ x = 40128

Hence, there are 40128 peoples in the parade route by proportion.

Step-by-step explanation:

The Vieth-Müller Circle is an imaginary circle that passes between both retinae and the fixation point.

The Vieth-Müller Circle is an ophthalmology concept that depicts an imaginary circle that passes across the foveas (the primary points of the retinae that are responsible for acute, detailed vision) and the fixation point (the point at which the eyes are directed).

The Vieth-Müller Circle is significant because it helps to explain the phenomenon of binocular vision, which is the ability to perceive depth and three-dimensional space using both eyes together. The circle aids in the definition of the equivalent locations on the two retinae, which are sites that receive visual field information and are critical in combining the images from the two eyes into a single, three-dimensional perception.

https://brainly.com/question/27123882

#SPJ4

The imaginary circle that passes through both retinae and the fixation point is called the horopter. The horopter is important in visual perception as it represents the set of points in space that stimulate corresponding points on each retina, which is necessary for binocular vision and depth perception.

The Horopter is an imaginary circle that passes through both retinae and the fixation point. In this context:

1. "Imaginary" refers to the fact that the Horopter is a theoretical concept rather than a physical object.
2. "Retinae" are the light-sensitive layers at the back of both eyes, which play a crucial role in processing visual information.
3. "Fixation" is the point where both eyes are focused on a single object in the visual field.

In brief, the Horopter represents a collection of points in the 3D space that are perceived as having the same depth or distance as the fixation point. It helps in understanding binocular vision and depth perception, as points on the Horopter contribute to forming a single, fused image from both eyes.

One benefit of statistical sampling compared to non-statistical sampling is that statistical sampling provides mathematically-sound methods to control for sampling risk. Statistical sampling techniques allow for the application of probability theory to estimate and control sampling errors and uncertainties.

By using statistical methods, one can determine the appropriate sample size, select samples randomly or systematically, and apply inferential statistics to make reliable inferences about the population being sampled. Non-statistical sampling, on the other hand, does not provide the same level of rigor in terms of controlling for sampling risk and may not yield reliable and representative results.

Therefore , the solution of the given problem of triangle comes out to be x = Tan⁻¹(15/8) .

Because a triangle has two or so more extra parts, it is a polygon. It has a straightforward rectangular shape. Only two of a triangle's three sides—A and B—can differentiate it from a regular triangle. Euclidean geometry produces a single area rather than a cube when boundaries are still not perfectly collinear. Triangles are defined by their three sides and three angles. Angles are formed when a quadrilateral's three sides meet. There are 180 degrees of sides on a triangle.

Here,

Given :

The unconfined compression strength of the clay sample is equal to the major stress at failure, which is 3,000 psf.

To determine the unconfined compression strength of the clay sample, given that the major stress at failure is 3,000 psf, you can follow these steps:

1. Identify the major stress at failure, which is 3,000 psf in this case.

2. The unconfined compression test measures the unconfined compressive strength (UCS) of the clay sample. Since there is no lateral confinement in this test, the major stress at failure is equal to the unconfined compressive strength.

3. Therefore, the unconfined compression strength of the clay sample is 3,000 psf.

In summary, the unconfined compression strength of the clay sample is equal to the major stress at failure, which is 3,000 psf.

The turkey farmer should guarantee a weight of 13.45 pounds to have to give her customers' money back only 1% of the time.

To determine the weight the turkey farmer should guarantee, we need to find the value that corresponds to the 99th percentile of the normal distribution. Using the mean (9.0 pounds) and standard deviation (2.8 pounds) provided, we can calculate this value.

To find the 99th percentile, we can use the Z-score formula: Z = (X - μ) / σ, where Z is the standard score, X is the value we're looking for, μ is the mean, and σ is the standard deviation. Rearranging the formula to solve for X, we have X = Z * σ + μ.

Since we want the 99th percentile, we need to find the Z-score that corresponds to that percentile. Using a standard normal distribution table or calculator, we find that the Z-score for the 99th percentile is approximately 2.33.

Plugging the values into the formula, we have X = 2.33 * 2.8 + 9.0 = 13.45 pounds. Therefore, the turkey farmer should guarantee a weight of at least 13.45 pounds to have to give her customers' money back only 1% of the time.

From the question we are told that:

Total Vegetarian Sandwiches Sold \(T_{vs}=75\)

Total Vegetarian Sandwiches Income \(T_{vi}=$712.50\)

Generally the equation for Cost of vegetarian sandwich is mathematically given by

 \(X=\frac{Total\ income\ from\ vegetarian\ sandwich}{No.\ of\ vegetarian\ sandwich\ sold}\)

Step-by-step explanation:

You want to know the area of a triangle with side lengths 13, 15, and 24 inches.

The area of a triangle can be found using Heron's formula:

  A = √(s(s -a)(s -b)(s -c)) . . . . . where s = (a+b+c)/2

For (a, b, c) = (13, 15, 24), the area is ...

  s = (13 +15 +24)/2 = 26

  A = √(26(26 -13)(26 -15)(26 -24)) = √(26·13·11·2) = 26√11

The area of the triangle is 26√11 square inches.
