Answer:

Angela needs 3 cups of flour, Jaleel 4

Step-by-step explanation:

Both get 6 cups of sugar when they divide it even. Then you set 6 for x and "solve" for y.

For Angela you can read the number from the graph, y = 0,5x

Angela needs a half cup of flour per whole cup of sugar.

Jaleel: get 6 cups of sugar too, you can easily double the cups from the table, which means 4 cups of flour with 6 cups of sugad

The solution to the system of equations is w = 0 and z = -2

Given equations are 3w - 4z = 8   ...(1)

2w + 3z = - 6          ...(2)

By multiplying the first equation by 3 and the second equation by 4, we get:

9w - 12z = 24        ...(3)

8w + 12z = -24      ....(4)

Adding equation (1) and (2)

17w + 0 = 0

w = 0

Putting the value of w in first equation

3(0) - 4z = 8

- 4z = 8

z = - 2

Therefore, the solution to the system of equations is w = 0 and z = -2

Applying law of sine and law of cosine, the unknown values x and y are 16.2 units and 37.1 degrees respectively.

To determine the value of x and y in the given triangle, we can use law of sine or law of cosine depending on the variables available and what we need to determine.

Applying law of cosine;

x² = 15² + 10² - 2(15)(10)cos78

x² = 225 + 100 - 300cos78

x² = 225 + 100 - 62.4

x² = 262.6

x = √262.6

x = 16.2 units

From this, we can apply law of sine to determine y;

x / sin X = y / sin Y

Substituting the values into the formula above;

16.2 / sin78 = 10 / sin y

Cross multiply both sides and solve for y;

16.2siny = 10sin78

sin y = 10sin78 / 16.2

sin y = 0.6038

y = sin⁻¹ (0.6038)

y = 37.14°

The calculation and record the answer with the correct number of significant figures. The final answer is 0.3724, accurate to four significant figures.

When performing calculations with significant figures, it is important to consider the precision of the numbers involved. In this case, we are adding 34.123 and 1.70, which gives us 35.823. The subtraction of 2.565 from 98.7654 gives us 96.1994.

To find the final result, we divide 35.823 by 96.1994, resulting in 0.372352. However, we must round the answer to the appropriate number of significant figures. Since 2.565 has the least number of significant figures (four), we round our answer to four significant figures as well.

Performing the calculation, we have:

(34.123 + 1.70) = 35.823

(98.7654 - 2.565) = 96.1994

Dividing the sum by the difference, we get:

35.823 / 96.1994 = 0.372352

Considering significant figures, we look at the least precise number, which is 2.565, with four significant figures. Therefore, our final answer should also have four significant figures.

Rounding the result to four significant figures, the answer is 0.3724.

The slope is 2 and the y-intercept is 6.

Given that an inequality y > -2x + 6, we need to graph it,

and determine the slope and the y-intercept of the same,

To determine the slope and y-intercept of the inequality y > -2x + 6, we can first rewrite it in the form of y = mx + b, where m represents the slope and b represents the y-intercept.

The given inequality can be rewritten as an equation by changing the inequality sign to an equal sign:

y = -2x + 6

Comparing this equation with the standard form y = mx + b, we can identify the slope and y-intercept:

The slope (m) is the coefficient of x, which is -2.

The y-intercept (b) is the constant term, which is 6.

Therefore, the slope of the equation y > -2x + 6 is -2, and the y-intercept is 6.

To graph the inequality y > -2x + 6, we'll start by graphing the corresponding equation y = -2x + 6.

Then, we'll determine which side of the line represents the solution to the inequality.

Graph the equation y = -2x + 6:

To plot the line, we'll need to find two points on it.

We can do this by assigning values to x and solving for y.

Let x = 0:

y = -2(0) + 6

y = 6

So, one point on the line is (0, 6).

Now, let's choose x = 3:

y = -2(3) + 6

y = 0

Another point on the line is (3, 0).

Plotting these two points, we can draw a straight line through them:

Determine the side of the line representing the solution:

Since the inequality is y > -2x + 6, we want to shade the area above the line.

Using a dashed line to represent the equation y = -2x + 6, we shade the region above the line to indicate y > -2x + 6

ii) The cost of fencing can be calculated by finding the perimeter of the land and multiplying it by the cost per meter. The perimeter of a rectangle is given by the formula P = 2(length + breadth).

Perimeter = 2(500m + 300m) = 2(800m) = 1600m

Cost of fencing = Perimeter * Cost per meter = 1600m * Rs.20 = Rs. 32,000

Therefore, the cost of fencing the land is Rs. 32,000.

iii) The area of the land remaining for farming can be calculated by subtracting the area of the farm house, the path around it, and the well from the total area of the land.

Area of the land = Length * Breadth = 500m * 300m = 150,000 sq.m

Area of the farm house = Length * Breadth = 20m * 30m = 600 sq.m

Area of the path around the farm house = (Length + 2width) * (Breadth + 2width) = (20m + 25m) * (30m + 25m) = 30m * 40m = 1200 sq.m

Area of the well = π * radius^2 = π * (3m)^2 = 9π sq.m

Area remaining for farming = Area of the land - Area of the farm house - Area of the path - Area of the well

= 150,000 sq.m - 600 sq.m - 1200 sq.m - 9π sq.m

Therefore, the area of the land remaining for farming is 150,000 sq.m - 600 sq.m - 1200 sq.m - 9π sq.m.

The output of 0.7326 represents the test statistic (Z-score) computed from the 1-sample Z-test in Excel.

It tells you how many standard deviations the sample mean is from the population mean under the null hypothesis.

A test statistic (Z-score) is a numerical value used in statistical hypothesis testing to assess the evidence against the null hypothesis.

A test statistic measures the difference between a sample statistic (eg sample mean) and the corresponding population parameter (eg population mean) assuming the null hypothesis is true.

For the Z-test, the test statistic is computed as

z = (x - μ) / (σ / √n)

where x = sample mean,

μ = population mean,

σ= population standard deviation,

and n = sample size.

The resulting Z-score indicates how many standard deviations the sample mean is from the population mean, assuming the null hypothesis is true.

Step-by-step explanation:

The bit pattern 0x0C000000 represents the decimal number 201326592 when interpreted as both a two's complement integer and an unsigned integer.

To determine the decimal representation of the bit pattern 0x0C000000, we need to consider whether it is interpreted as a two's complement integer or an unsigned integer.

If the bit pattern is interpreted as a two's complement integer, we follow these steps:

Check the most significant bit (MSB). If it is 0, the number is positive; if it is 1, the number is negative.

In this case, the MSB of the bit pattern 0x0C000000 is 0, indicating a positive number.

Convert the remaining bits to decimal using the positional value of each bit. Treat the MSB as the sign bit (0 for positive, 1 for negative).

Converting the remaining bits, 0x0C000000, to decimal gives us 201326592.

Therefore, if the bit pattern 0x0C000000 is interpreted as a two's complement integer, it represents the decimal number 201326592.

If the bit pattern is interpreted as an unsigned integer, we simply convert the entire bit pattern to decimal.

Converting the bit pattern 0x0C000000 to decimal gives us 201326592.

Therefore, if the bit pattern 0x0C000000 is interpreted as an unsigned integer, it represents the decimal number 201326592.

Step-by-step explanation:

ake it or leave it

The best explanation graph is a better representation of the data below: "The line graph because it shows how the number of miles increases over the number of minutes."

A graph can be defined as a visual representation or a diagram that represents data or values.

The distance in miles a car travels over time in minutes is shown in the table.

Distance (miles)    Time (minutes)

    10                                 15

   20                                 30

   30                                 45

   40                                 60

A line graph is a good choice for representing data that show a change in value over time. In this case, the value being measured is the distance in miles traveled, and the time is being used as the variable. A line graph is a good choice because it can show the change in distance over time, which is what the data represents.
