To develop an equation to predict the surface area of a person as a function of their height and weight using numerical methods and MATLAB, you can follow these steps:

The required details for MATLAB in given paragraph

Begin by organizing the given data into two separate arrays: one for height (H) and one for weight (W). For example, you might create the following arrays:

H = [182 180 179 187 189 194 195 193 200];

W = [74 88 94 78 84 98 76 86 96];

A = [1.92 2.11 2.15 2.02 2.09 2.31 2.02 2.16 2.31];

Use the MATLAB function "polyfit" to fit a polynomial function to the data. You can specify the degree of the polynomial function based on the number of variables you want to include in the model. For example, to fit a second-degree polynomial function, you can use the following command:

p = polyfit(H,A,2);

This will fit a polynomial function of the form A = p(1) * H^2 + p(2) * H + p(3) to the data, where p(1), p(2), and p(3) are the coefficients of the polynomial.

Use the MATLAB function "polyval" to evaluate the fitted polynomial function at a specific value of H. For example, to estimate the surface area for a person with a height of 187 cm, you can use the following command:

A_estimated = polyval(p,187);

This will return the estimated surface area for a person with a height of 187 cm. You can use similar commands to estimate the surface area for different values of H

what do you mean by MATLAB?

MATLAB (short for "Matrix Laboratory") is a programming language and software environment for numerical computation, visualization, and programming. It is commonly used in scientific, engineering, and mathematical fields to analyze and visualize data, develop algorithms, and build mathematical models.

A function in MATLAB is a self-contained block of code that performs a specific task or computation. Functions are useful because they allow you to reuse code and make your programs more modular and easier to understand. In MATLAB, you can define your own functions or use built-in functions that are provided with the software.

Answer:

7 kg

Step-by-step explanation:

Newton's second law tells us that Force = Mass * Acceleration, also known as F = ma.

The downward acceleration due to gravity on Earth is usually taken to be 9.8 ms^-1.

Substitute the values into the equation:

68.6 = m * 9.8

Rearrange and simplify:

m = 68.6 / 9.8

m = 7 kg

Answer:

the football team sells 805,000 tickets each season

Step-by-step explanation:

average number of tickets sold per match=23,000

the average number of games played each session=35

the number of tickets sold on average each session = 23,000 x 35 which equals 805,000

so the average football club sells 805,000 tickets each season

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Two congruent parallelograms are joined along their base to make the shape below.

Now,

We know that;

2 identical parallelogram whose area = 2 (Base x Height)

And, 2 identical right triangle = base x height

And, 1 rectangle = length x width

So, We get;

In parallelogram;

Base = 15 cm

Height = 11 cm

Hence, We get;

Area = 2 (15 x 11)

       = 330 cm²

And, Area of two identical right triangle;

Base = 11 cm

Height = 11 cm

Hence, Area = 11 × 11

                    = 121 cm²

Area of rectangle = 18 x 15 = 270 cm²

The complete question is;

A house has seven rooms. Each room can be painted white or yellow. How many possible outcomes are there?

BY using the inequality,

(67 + 65 + 64 + 88 + 2x)/5 ≥ 73,

we find the score she must make on final exam to pass the courses with an average of 73 or higher is x>=80.

An inequality is a mathematical statement that shows that one quantity is greater than or less than another quantity.

The average, or mean, of a set of numbers is a measure of the central tendency of the set.

This inequality states that the average of Shureka's scores on the four tests and the final exam must be greater than or equal to 73 in order for her to pass the course. Solving for x, we find that x ≥ 80.

The meaning of the answer to part (a) is that Shureka must make a score of 80 or higher on the final exam in order to pass the course with an average of 73 or higher. In other words, if Shureka makes a score of 80 or higher on the final exam, her average score on the five tests will be 73 or higher, which is the minimum required to pass the course. If she makes a score lower than 80 on the final exam, her average score will be less than 73, and she will not pass the course.

Answer: 4 red and 12 blue

Step-by-step explanation: Answer to 9

We know that for every red rose, he plants 3 blue flowers. The rate is 1:3. If he grows 16, there will be 4 red roses and 12 blue ones. This is because the rate is 1:3 then there are 4 flowers in all. This is 1/4 of how much he wants to grow. So multiply each type of plant by 4. 1 times 4 is 4, so there are 4 red ones. 3 times 4 is 12, so there are 12 blue ones. Hope this helps!

Area under the given standard normal curve for the z-score between 0.97 to 1.26 is equal to 0.06219.

As given in the question,

Given values to find area under the standard normal curve = 0.97 to 1.26

From the table of area under the given standard normal curve

z - score of 0.97 is equal to 0.33398

z-score of 1.26 is equal to 0.39617

Area under given standard normal curve between z-scores 0.97 and 1.26

= P ( 0.97 < z < 1.26 )

= 0.39617 - 0.33398

= 0.06219

Option B is the graph best represents the most reasonable distribution of the differences.

Any variable whose value is uncertain or any function that values each result of an experiment is referred to be a random variable. Discrete (having definite values) or continuous random variables are also possible (any value in a continuous range).

As a result, the random variables are so-called because it is impossible to determine their value with certainty; instead, we can only guess, and this estimate is known as the probability that a random variable will have a given value.

Here we assume the random variable X denotes the difference between the outcomes of rolling the two dice.

here the number of rolls is 500. As we know by central limit theorem every distribution approaches to normal distribution irrespective of the parent distribution. Since Normal is symmetric about the mean the most reasonable distribution is the second figure.

a) The probability that both are girls is of: 21/150.

b) The probability that both are from the same school is of: 0.7333 = 73.33%.

How to obtain the probabilities?

The probabilities are obtained as the division of the number of desired outcomes by the number of total outcomes.

For item a, the outcomes are given as follows:

One girl from school A -> 7/15 probability.

One girl from school B -> 3/10 probability.

Hence the probability that both are girls is of:

p = 7/15 x 3/10 = 21/150.

The probability that the two boys are from the same school can be given by these two cases:

School A: 8/15 x 7/14.

School B: 7/10 x 6/9.

Then the probability is of:

p = 8/15 x 7/14 + 7/10 x 6/9 = 0.7333 = 73.33%.

Rows and columns serve as a measure of a matrix's dimensions. Given that it has three rows and three columns, for instance, the matrix below has a dimension of 3 x 3. Three by three can be read off as the matrix's dimension. We consequently obtain the additive inverse of the matrix

Answer:

Step-by-step explanation:

You want the (a) post-order, and (b) pre-order list of visited vertices in a traversal of the tree described by {root, left, center, right}: {d, f, {b, i, h, e}, {a, {c, g}}}.

A tree is traversed in post-order by visiting the left branch, center branch, and right branch before the root. This is accomplished recursively.

For the given tree, the root 'd' has left branch 'f' which has no branches. That means node 'f' is reported first.

The middle branch goes to 'b' which has three branches. Those are reported before their root 'b'.

The right branch from root 'd' goes to 'a', which has branch 'c' going to 'g'. So, 'g' is reported, then 'c', then 'a'.

Finally, 'd' is reported.

Hence, the post-order traversal is f, i, h, e, b, g, c, a, d.

The pre-order traversal reports the root node, then the left, center, and right nodes, recursively. The vertices are effectively visited in the order in which we have defined the tree above: d, f, b, i, h, e, a, c, g.
