suppose the download of large file takes, on average, 12 minutes, with a standard deviation of 2 minutes. if the download time follows a gamma distribution, what are α and λ ?

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new location is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

a) The scale factor from Quadrilateral A to Quadrilateral B = smallest side length of side B / smallest side length of side A = 2 / 6 = 1/3

Scale factor = 1/4= 1 / 3

The side length of 6 in A corresponds to a side length of 2 in B

Side length of B that corresponds with side length of 9 in A = scale factor * 9 =  1/3 * 9 = 3

The side length of 9 in A corresponds to a side length of 3 in B

Side length of B that corresponds with side length of 12 in A = scale factor * 9 =  1/3 * 12 = 4

The side length of 12 in A corresponds to a side length of 4 in B.

c)  perimeter of Quadrilateral B = sum of side lengths of quadrilateral B = 2 + 3 + 3 + 4 = 12 units

Here's a MATLAB code to find the sum and product of the diagonal elements of a given matrix `A`, as well as an example execution for `A = ones(5)`:

```matlab

% Define the matrix A

A = ones(5);

% Get the size of the matrix

[n, ~] = size(A);

% Initialize variables for sum and product

diagonal_sum = 0;

diagonal_product = 1;

% Calculate the sum and product of diagonal elements

for i = 1:n

   diagonal_sum = diagonal_sum + A(i, i);

   diagonal_product = diagonal_product * A(i, i);

end

% Display the results

disp("Sum of diagonal elements: " + diagonal_sum);

disp("Product of diagonal elements: " + diagonal_product);

```

Example execution for `A = ones(5)`:

```

Sum of diagonal elements: 5

Product of diagonal elements: 1

```

In this example, `A = ones(5)` creates a 5x5 matrix filled with ones. The code then iterates over the diagonal elements (i.e., elements where the row index equals the column index) and accumulates the sum and product. Finally, it displays the computed sum and product of the diagonal elements.

0.1678 is the probability that all the light bulbs work

Define probability?

Probability is a branch of mathematics and can be defined as the one which deals with the explanation of the possibility of an event to occur or take place. Probability has a range between 0 to 1. In probability, 0 indicates the impossibility of an event to occur and 1 indicates the certainty of that event to occur or take place.

As the light bulbs are not dependent on each other and work independently, the probability that all eight of the light bulbs will work can be calculated by multiplying the probability of each of the eight light bulbs.

As the probability of each of the eight light bulbs to work = 0.8

probability all the eight light bulbs work = 0.8^8

probability all the eight light bulbs work = 0.1678

Hence, 0.1678 is the probability that all the light bulbs work.

Answer:

Area: 120m²

Flowers: 600kg

Step-by-step explanation:

we can use Heron's formula to solve for the area.

Heron's formula:

Area of triangle = \(\sqrt{ s(s-a)(s-b)(s-c)}\)

s = 1/2 (a+b+c)

s = 1/2 (10 +24+26)

s = 30

Area of triangle

\(=\sqrt{30(30-10)(30-24)(30-26)} \\=120m^{2}\)

Since every 1 m² of area can grow 5kg of flowers,

the yield of flowers will be:

'h' = heather's age

sue = 'l + 2' but, since 'l' is 2h we can say sue's age is '2h+2'

l = 2h

2h+2 + 2h + h = 27

5h = 25

h = 5

l = 2(5) = 10

The area of triangle ABC is 6 square units.

To find the area of triangle ABC, we need to know the lengths of its base and height.

Looking at the given diagram, we can see that the base of triangle ABC is the line segment AC, and the height is the vertical distance from point B to line AC.

From the diagram, it is clear that the base AC has a length of 3 units.

To determine the height, we need to find the perpendicular distance from point B to line AC.

By visually inspecting the diagram, we can observe that the height from point B to line AC is 4 units.

Now, we can use the formula for the area of a triangle, which is given by:

Area = (1/2) \(\times\) base \(\times\) height

Plugging in the values, we get:

Area = (1/2) \(\times\) 3 \(\times\) 4

= 6 square units

Therefore, the area of triangle ABC is 6 square units.

Based on the provided answer choices, none of the options match the calculated area of 6 square units.

jhdbjhzhjzhdfhkskuKJHFDhHKGHFgHLgfslhalghlhirfhhcguhdfgfhdycthguerStep-by-step explanation:

Sample size and the confidence level width have an inverse relationship. As the sample size increases, the confidence level width decreases.

When determining a confidence interval for a population parameter, such as the mean or proportion, a larger sample size provides more information about the population. This increased information leads to a narrower confidence interval.

The confidence level width is influenced by two factors: the sample standard deviation (or the variability of the data) and the critical value associated with the desired confidence level. As the sample size increases, the sample standard deviation becomes a more accurate estimate of the population standard deviation. This reduces the variability and leads to a narrower confidence interval.

A larger sample size leads to a decrease in the confidence level width, providing a more precise estimate of the population parameter with a higher level of confidence.

No, a reaction does not occur when aqueous solutions of chromium(II) bromide and aluminum acetate are combined. To determine if a reaction occurs between chromium(II) bromide (CrBr2) and aluminum acetate (Al(CH3COO)3).

We need to consider the solubility rules and potential chemical reactions between the ions. According to the solubility rules, bromides (Br-) are generally soluble in water, and acetates (CH3COO-) are also soluble. Therefore, both chromium(II) bromide and aluminum acetate will dissociate into their respective ions when dissolved in water.

The ions present in chromium(II) bromides are Cr2+ and Br-. The ions present in aluminum acetate are Al3+ and CH3COO-. When these solutions are combined, there are no double replacement reactions or precipitation reactions that occur between the ions.

Since there is no reaction between the ions, we can conclude that no new compounds or products are formed. Hence, the answer is that no reaction occurs when aqueous solutions of chromium(II) bromide and aluminum acetate are combined. As no net ionic equation is required in this case, the explanation above is sufficient to state that there is no reaction between chromium(II) bromide and aluminum acetate.

Answer:

C

Step-by-step explanation:

a and c are directly proportional to each other when a and b are directly proportional and b and c are directly proportional.

If a and b are directly proportional and b and c are directly proportional, it means that their ratios are equal. Direct proportionality implies that as one variable increases, the other also increases in proportion and as one variable decreases, the other also decreases in proportion.

Mathematically, this can be written as

a = kb and b = mc, where k and m are constants of proportionality.

Multiplying these two equations gives: a = kbm

Substituting the value of b from the second equation in the first equation, we get: a = kmc

Therefore, a and c are also directly proportional to each other with a constant of proportionality km.

Thus, if a increases by a certain factor, c will also increase by the same factor.

If a and b are directly proportional and b and c are directly proportional, then it can be concluded that a and c are directly proportional as well.
