a) There are 2400 animals on the farm.

b) The number of sheep on the farm is 700.

c) The percentage of rabbits in relation to the total number of animals is 37.5%.

d) The angle that represents the number of pigs is 75 degrees.

a) To determine the total number of animals on the farm, we add up the number of rabbits, sheep, cattle, and pigs:

Total number of animals = 900 (rabbits) + 700 (sheep) + 300 (cattle) + 500 (pigs) = 2400 animals.

b) The number of sheep on the farm is given as 700.

c) To calculate the percentage of rabbits in relation to the total number of animals, we divide the number of rabbits by the total number of animals and multiply by 100:

Percentage of rabbits = (900 / 2400) * 100 = 37.5%.

d) To calculate the angle that represents the number of pigs, we need to find the proportion of the total number of animals that pigs make up, and then convert it to an angle on the pie chart.

Proportion of pigs = 500 / 2400 = 0.2083.

To find the angle in degrees, we multiply the proportion by 360 degrees:

Angle representing pigs = 0.2083 * 360 = 75 degrees.

The x-intercepts represent a zero profit, the maximum value of the graph represents the maximum profit, An approximate average rate of change of the graph from x=3  to x=5 represents the reduction in profit from 3 to 5 and the domain is constrained by x=0.

Part A:

The x-intercepts represent a zero profit.

The maximum value of the graph represents the maximum profit.

The function increases up till the vertex and decreases after it.

This means that the profit increases as it reaches the peak at the vertex.

It decreases after the vertex up till it reaches zero.

On the left of the first zero and on the right of the second zero, the profits are negative.

Part B:

An approximate average rate of change of the graph from x=3  to x=5 represents the reduction in profit from 3 to 5.

Part C:

Simply, the domain is constrained by x=0.

We are obliged at x=6 .

The given graph shows that the function is periodic and fluctuates between y = -2 and y = 2. So, the range of the function is [-2,2].

The graph covers one period, which is from x = -3 to x = 3, and then repeats itself indefinitely in both directions. So, the domain of the function is (-∞, ∞).

In general, the domain of a function consists of all the possible input values that the function can take. In this case, since the function repeats itself indefinitely, it can take any input value from negative infinity to positive infinity.

So, the domain is (-∞, ∞). The range of a function, on the other hand, consists of all the possible output values that the function can produce.

In this case, the function oscillates between y = -2 and y = 2, so the range is [-2,2]. The interval notation for the domain is (-∞, ∞) and for the range is [-2,2].

The percentage of a discount on a blouse will be 21.87%.

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

It is given that Sue bought a blouse for $96 and received a discount amount of $28.

The discount percentage will be calculated as below:-

First, calculate the total cost of the blouse that adds the actual price and the discount amount.

Total price = 96 + 28 = 128

The percentage discount will be calculated as below:-

Discount percentage = 28 / 128 = 27.87%

Answer:

y = 1/4x - 7/2

Step-by-step explanation:

To answer this question, we have to use point-slope form:

y - y1 = m(x - x1)

Substitute the numbers into the variables:

y - (-4) = 1/4(x - (-2))

y + 4 = 1/4(x + 2)

y + 4 = 1/4x + 1/2

y = 1/4x - 7/2

To verify your answer, simply substitute the values into your equation:

-4 = 1/4(-2) - 7/2

-4 = -1/2 - 7/2

-4 = -8/2

Answer:

-5

Step-by-step explanation:

Slope- intercept form:

y= mx +c, where m is the slope and c is the y-intercept

Since the given equation is already in the slope-intercept form, we can identify its slope by looking at the coefficient of the x term. Here the coefficient is -5, thus the slope of the given line is also -5.

Parallel lines have the same slope. Thus, the slope of the line that is parallel to y= -5x +7 will have a slope of -5.

Hello there! (:

Parallel lines have the same slope.

We are given that one line has a slope of -5, therefore, the line parallel to the given line has a slope of -5 as well.

Answer:

Option A is correct.

The correct graph that represents the given compound inequality -2x + 5 < 7 and 5x - 4 ≤ 6 is: graph D.

In Mathematics, it is very important for students to note that they do not flip the inequality symbol (sign) when you are solving an inequality by multiplication or division with a positive numerical value (number).

Next, we would simplify each of the compound inequality as follows;

-2x + 5 < 7

Subtracting 5 from both sides of the inequality, we have the following:

-2x + 5 - 5 < 7 - 5

-2x < 2

Dividing both sides of the inequality by -2, we have the following:

-2x/-2 < -2/2

x < -1

Next, we would flip the inequality symbol (sign) because it was divided by a negative numerical value (number);

x > -1

Simplifying 5x - 4 ≤ 6, we have;

5x - 4 + 4 ≤ 6 + 4

5x ≤ 10

x ≤ 10/5

x ≤ 2

Therefore, the compound inequality {x > -1 and x < 2} can be re-written as follows;

-1 < x ≤ 2

Answer:

The mean of the sampling distribution of the sample proportions is the same as the population proportion, which is 0.67.

The standard deviation of the sampling distribution of the sample proportions can be calculated using the formula:

σp = sqrt [p * (1 - p) / n]

where p is the population proportion (0.67), n is the sample size (64), and σp is the standard deviation of the sampling distribution of the sample proportions.

Plugging in the values, we get:

σp = sqrt [0.67 * (1 - 0.67) / 64]

= sqrt [0.2211 / 64]

= 0.061

Therefore, the standard deviation of the sampling distribution of the sample proportions is 0.061.

Thus, 715,000 =  7.15 x 10⁵, using the concept of scientific notations, both the values are found to be equal.

The number of times that decimal point must be moved to obtain a number between 1 and 10 is the exponent in scientific notation. The decimal point is shifted to the left in order to represent this number in scientific notation.

The main goal of scientific notation is to simplify computations using numbers that are abnormally large or small. With scientific notation, every digit counts because zeros are just no longer used to denote the decimal point.

Given expression:

715,000 __ 7.15 x 10⁵

LHS = 715,000

Take the RHS value :

= 7.15 x 10⁵

This, can be simplifies as:

= 7.15 x 100,000

Now multiply the two values,

= 715,000 (RHS values)

as, LHS  = RHS

LHS = 715,000

715,000 (RHS values)

Thus, 715,000 =  7.15 x 10⁵, using the concept of scientific notations, both the values are found to be equal.
