The heights of giraffes are known to be normally distributed (That is we expect them to have a bell-shaped histogram) with a mean of 156 inches and a standard deviation of 15 inches. What percent of giraffes have a height between 141 and 171 inches
Percent of giraffes have a height between 141 and 171 inches is approximately 68%
Given data are Mean μ = 156Standard Deviation σ = 15Now, we need to find the probability of giraffes with height between 141 and 171 inches. Here, we need to find the z-scores for the given height range.x1 = 141 inches, μ = 156, σ = 15 z1 = (x1 - μ) / σ = (141 - 156) / 15 = -1x2 = 171 inches, μ = 156, σ = 15 z2 = (x2 - μ) / σ = (171 - 156) / 15 = 1
The probability of giraffes with height between 141 and 171 inches is P(141 < X < 171) = P(-1 < Z < 1)We can find this by using the standard normal distribution table The probability of giraffes with height between 141 and 171 inches is P(-1 < Z < 1) = 0.6826Therefore, approximately 68% of giraffes have a height between 141 and 171 inches.

can you find the determinant of a non square matrix
No, the determinant of a matrix can only be calculated for square matrices. A square matrix has an equal number of rows and columns, while a non-square matrix has a different number of rows and columns.
The determinant is a mathematical property that is defined for square matrices only. It is a scalar value that represents certain characteristics of the matrix. To calculate the determinant of a square matrix, you can use various methods such as expansion by minors, cofactor expansion, or using the properties of determinants.
For example, let's consider a 3x2 non-square matrix:
```
A = [[1, 2],
[3, 4],
[5, 6]]
```
Since A is a non-square matrix, we cannot calculate its determinant.
the determinant is a concept applicable only to square matrices. Non-square matrices do not have a determinant.

Which factor provides the basis for the grading of newly diagnosed malignant tumors? size of the tumor x number of metastases degree of differentiation of the cells number of lymph nodes involved
The factor that provides the basis for the grading of newly diagnosed malignant tumours is degree of differentiation.
What is the degree of differentiation?The level of differentiation impacts an individual's capacity to control their emotions, thoughts, individuality, and connections to others. The degree of any differential equation can be obtained when it is expressed as a polynomial; otherwise, the degree cannot be defined.
The mechanisms by which immature cells develop into mature cells with particular roles are described in biology. This indicates the degree to which tumour tissue resembles the healthy tissue from which it originated in the context of cancer. Compared to poorly or undifferentiated cancer cells, well-differentiated cancer cells resemble normal cells more and grow and spread more slowly. Tumour grading systems, which vary for each form of cancer, use differentiation.

a triangle has an area of 11 square feet. if another similar triangle has corresponding sides with 3 times the length of the first triangle, what is its area?
According to the statement the area of the second triangle is 99 square feet.
To find the area of the second triangle, we can use the fact that the ratio of the areas of similar figures is equal to the square of the ratio of their corresponding sides.
In this case, the corresponding sides of the second triangle are 3 times the length of the first triangle.
Since the area of the first triangle is given as 11 square feet, we need to find the square of the ratio 3:1.
The ratio of the corresponding sides is 3:1, so the ratio of their lengths is 3:1 as well.
Squaring this ratio, we get
(3²) : (1²) = 9 : 1.
Now, we can use this ratio to find the area of the second triangle.
Since the area of the first triangle is 11 sq ft, we can set up the equation:
11 sq ft x (9:1) = x sq ft
Simplifying this, we get:
99 sq ft = x sq ft
Therefore, the area of the second triangle is 99 sq ft.

The area of the second similar triangle, with corresponding sides 3 times the length of the first triangle, is 891 square feet. The area of a triangle is determined by multiplying the base by the height and dividing the result by 2.
In this case, the first triangle has an area of 11 square feet. To find the area of the second similar triangle, we need to consider that the corresponding sides are 3 times the length of the first triangle.
Let's assume the base and height of the first triangle are "b" and "h" respectively. So, the area of the first triangle can be calculated as \(\frac{bh}{2} = 11\).
Now, the corresponding sides of the second triangle are 3 times longer. This means the base and height of the second triangle will be 3b and 3h respectively. Therefore, the area of the second triangle can be calculated as \(\frac{3b\times 3h}{2}\)
Substituting the values, we get \(\frac{9b\times 9h}{2}\). Simplifying further, the area of the second triangle is 81 times the area of the first triangle, which is 891 square feet.
In conclusion, the area of the second similar triangle, with corresponding sides 3 times the length of the first triangle, is 891 square feet.

Answer:
3.14 times 4 equal 12.56
The requried arc length of the partial circle with a radius of 4 and a central angle of 270 degrees is 6π units, or approximately 18.85 units if using 3.14 as an approximation for π.
What is the perimeter?Perimeter is the measure of the figure on its circumference.
Here,
When the central angle of a circle is given in degrees, we can use the formula for arc length:
arc length = (Ф/360) x 2πr
Here, the radius is given as 4, and the central angle theta is 270 degrees. Substituting these values into the formula,
arc length = (270/360) x 2π(4)
arc length = (3/4) x 2π(4)
arc length = (3/4) x 8π
arc length = 6π
Therefore, the arc length of the partial circle with a radius of 4 and a central angle of 270 degrees is 6π units, or approximately 18.85 units if using 3.14 as an approximation for π.

x² + y² +16y + 40 = 8x + 4y; center
To find the center of the given equation, we need to rewrite it in the standard form of a circle equation, which is:
\(\sf\:(x - h)^2 + (y - k)^2 = r^2 \\\)
where (h, k) represents the center coordinates of the circle and r represents the radius.
Given equation:
\(\sf\: x^2 + y^2 + 16y + 40 = 8x + 4y \\\)
Rearranging the terms:
\(\sf\:x^2 - 8x + y^2 + 16y - 4y = -40 \\\)
Completing the square for the x-terms:
\(\sf\: (x^2 - 8x + 16) + y^2 + 12y - 4y = -40 + 16 \\\)
Completing the square for the y-terms:
\(\sf\: (x^2 - 8x + 16) + (y^2 + 12y + 36) = -40 + 16 + 36 \\\)
Simplifying:
\( \sf\:(x - 4)^2 + (y + 6)^2 = 12 \\\)
Comparing this with the standard form, we can see that the center of the circle is at (4, -6).

A delivery company samples 500 orders and records how many deliveries were early (before quoted delivery date, yes or no). Out of 500 records, 300 of them were delivered early. The company is interested in seeing if they have statistical evidence that they deliver early a majority of the time. a. Write down the null and alternative hypothesis using proper notation. b. What is the estimate of the true proportion of all orders that are delivered early
a) We can express this as: Ha: p > 0.5 where p represents the true proportion of all orders that are delivered early.
b) The estimate of the true proportion of all orders that are delivered early is 0.6 or 60%.
Learn The null hypothesis would be that the company does not deliver early a majority of the time, or in other words, the true proportion of early deliveries is equal to or less than 0.5. We can express this as:
H0: p <= 0.5
The alternative hypothesis would be that the company delivers early a majority of the time, or in other words, the true proportion of early deliveries is greater than 0.5. We can express this as:
Ha: p > 0.5
where p represents the true proportion of all orders that are delivered early.
b.
The estimate of the true proportion of all orders that are delivered early is simply the proportion of early deliveries observed in the sample. From the information given, we know that out of 500 orders sampled, 300 of them were delivered early. Therefore, the sample proportion of early deliveries is:
p-hat = 300 / 500 = 0.6
So the estimate of the true proportion of all orders that are delivered early is 0.6 or 60%.

_ is considered fully transferable
In the context of property rights, an asset is considered fully transferable.
When its ownership can be easily and completely transferred from one person to another without any restrictions or limits. This transferability allows for greater efficiency in the market, as it enables assets to be allocated to those who value them the most and can utilize them most effectively.
One common example of a fully transferable asset is a share of stock in a publicly traded company. These shares can be bought and sold freely in the stock market, allowing for a seamless transfer of ownership between parties. This transferability benefits both buyers and sellers, as it provides an accessible platform for trading and allows for price discovery based on supply and demand.
However, not all assets are fully transferable. Some assets, such as real estate or certain types of intellectual property, may have restrictions on their transferability due to legal, regulatory, or contractual requirements. These restrictions can limit the efficiency of the market and may result in suboptimal allocation of resources.
Overall, transferability is an important characteristic of assets in a market economy, as it enables efficient allocation of resources and encourages investment by providing a clear and straightforward mechanism for changing ownership.
