The rand value of a camera that costs 6 840,45 yuan is R9,370.47.

A currency's relative value expressed in terms of another currency is called an exchange rate (or group of currencies). The exchange rate is a significant economic variable for nations with active international trade, like Australia.

Given:

The camera that costs 6 840,45 yuan in China.

As, the exchange rate is R1 = 0.73 yuan.​

so, the Rand value of Camera

= 6840.45 / 0.73

= R9,370.47

Answer:

Rounding to the nearest minute, the time it will take for Amanda and Hannah to be 16 kilometers apart on the river is 53 minutes.

Step-by-step explanation:

Let's call the time it takes for Amanda and Hannah to be 16 kilometers apart "t" (in hours). During this time, Amanda will have kayaked down the river a distance of 9t kilometers, and Hannah will have jet-skied up the river a distance of 42t kilometers. So, their total separation will be 9t + 42t = 51t kilometers. Setting this equal to 16, we get:

51t = 16

t = 16 / 51

To convert this to hours and minutes, we can multiply by 60 to convert the fraction to minutes:

t = 16 / 51 * 60 = approximately 53.33 minutes

Ways can n identical balls be distributed into r bins such that each bin contains at least two balls are 20 ways.

1 ball in each of 3 boxes: 4 ways

3 balls in one box: 4 ways

2 balls in one box and 1 ball in another box: 3*4=12 ways

There are 20 ways to arrange the balls .

In mathematics, a combination is a way of selecting items from a collection where the order of selection does not matter. Suppose we have a set of three numbers P, Q and R. Then in how many ways we can select two numbers from each set, is defined by combination.

The combination can also be represented as: –nCr, nCr, C(n,r), Crn

Proof:

nPr = nCr.r!

= [n!/r!(n-r)!].r!

= n!/(n-r)!

Hence the theorem states true.

A permutation is an act of arranging objects or numbers in order. Combinations are the way of selecting objects or numbers from a group of objects or collections, in such a way that the order of the objects does not matter.

Step-by-step explanation:

There are several reasons why a couple percent error may occur when calculating roots, even if both roots can easily be represented with a float.

These reasons can include rounding errors, numerical instability, algorithm limitations, machine precision, and incorrect input data or model. To minimize the error, it is important to use a stable and accurate algorithm, and to ensure that the input data and model are correct.

The error in the calculation of one of the roots can be due to several reasons, such as:

Rounding errors: In many cases, when performing calculations with floating-point numbers, intermediate results are rounded to a certain number of decimal places. This can result in a small error that accumulates throughout the calculation and leads to an incorrect answer.

Numerical instability: Some mathematical operations, such as division and square roots, can lead to loss of precision or numerical instability. This can result in an incorrect answer, even if the input numbers can be represented as floating-point numbers.

Algorithm limitations: The algorithm used to calculate the roots may have limitations that result in an error, even if the input numbers can be represented as floating-point numbers. For example, some algorithms may not converge to the correct root, or they may converge very slowly.

Machine precision: The precision of the computer used to perform the calculation can also play a role in the error. For example, if the computer uses single-precision floating-point numbers instead of double-precision floating-point numbers, the error will be larger.

Model or input data error: The error could also be due to incorrect input data or an incorrect model. For example, if the mathematical model used to calculate the roots is not an accurate representation of the underlying system, the error will be larger.

The matrix must have pivot columns. Otherwise, the equation Ax = 0 would have a free variable, in which case the columns of A would not span R5. Therefore, the correct answer is C.

A pivot column is a column of the matrix that has a non-zero entry in the pivot position and all entries below the pivot are zero. In row echelon form, every row below a pivot column has a zero in the corresponding position. The pivot columns correspond to the linearly independent columns of the original matrix and the number of pivot columns determines the rank of the matrix.

The rank of a matrix is defined as the number of linearly independent columns or rows in the matrix. If the columns of a matrix span Rn, then the rank of the matrix must be equal to n. This means that the matrix must have n linearly independent columns. To ensure that the columns of A span R5, A must have at least 5 pivot columns. If A had fewer pivot columns, then the equation Ax = 0 would have a non-trivial solution, meaning that the columns of A would not be linearly independent and would not span R5.

The probability of drawing 5 cards from Ms Q's deck such that three cards have the same number is 876 / 98 = approximately 0.089.

There are a total of 28 possible combinations of 5 cards from Ms Q's deck since there are 4 colours and 7 numbers.

To have three cards with the same number, Yunseol must choose 3 cards with the same number and 2 cards with different numbers. There are 7 possible choices for the number of the three cards, and 4 choices for the colour of each card, so there are 7 × 4³ = 196 ways to choose the 3 cards.

For the other 2 cards, Yunseol must choose 2 different numbers and 2 different colours, so there are 7 choose 2 (or 21) ways to choose the numbers and 4 choose 2 (or 6) ways to choose the colours. Therefore, there are 21 × 6 = 126 ways to choose the other 2 cards.

So, the total number of ways to have 3 cards with the same number is 196 × 126 = 24536.

The probability of having three cards with the same number is 24536 / 28 = 876 / 98.

Therefore, the probability of drawing 5 cards from Ms Q's deck such that three cards have the same number is 876 / 98 = approximately 0.089.

Scott picked x pounds of blueberries from a local farm and if Scott picked x pounds of blueberries, he now has 5 pounds, so x = 5(2) = 10 pounds.

Pounds is a unit of mass or weight used in the imperial and United States customary systems of measurement. It is equal to 16 ounces or 0.45 kilograms. In the United Kingdom and the other countries that use the imperial system of measurement, it is the standard unit used to measure the weight of people, animals and other objects. In the United States, the pound is often referred to as the avoirdupois pound to differentiate it from other units of measure.

He gave 3 pounds of his pick to his brother, Dean. This leaves x-3 pounds of blueberries. He then shared the remaining blueberries equally with his sister Georgia, so each of them got (x-3)/2 pounds of blueberries. This means that Scott has (x-3)/2 + 3 = (x+3)/2 pounds of blueberries. Therefore, if Scott picked x pounds of blueberries, he now has 5 pounds, so x = 5(2) = 10 pounds.

Answer:

Based on the information, the most appropriate graph to construct with the data given in the table to observe how miles change over a certain number of days would be a line graph because it would show how a variable changes over time between each individual data point. .

What is the appropriate graph for this data?

To select the appropriate graph for these data we must take into account the following aspects. The data being linked.

In accordance with the above, we want to relate data of days with distance. Therefore, the best option would be the line graph since it allows us to relate two data and in turn contrast the difference with other points.

So the correct answer would be a line graph because it would show how a variable changes over time between each individual data point (option A).

Step-by-step explanation:

The complete table for the linear function is:

x =    -1, -2/3, -1/3, 1/3

f(x) = -1,    0,    1,     3

And the inverse is:

g(x) = (x - 2)/3

Here we want to complete the table for the linear function:

f(x) = 3x + 2

To do so, we just need to evaluate the function in the given x-values on the table.

f(-1) = 3*-1 + 2 = -1

f(-2/3) = 3*(-2/3) + 2 = 0

f(-1/3) = 3*(-1/3) + 2 = 1

f(1/3) = 3*(1/3) + 2 = 3

Then the complete table is:

x =    -1, -2/3, -1/3, 1/3

f(x) = -1,    0,    1,     3

And i assume that we also want to find the inverse g(x), then we need to solve:

f(g(x)) = x

3*g(x) + 2 = x

g(x) = (x - 2)/3
