"An integer is the number 0 or any number obtained by repeatedly adding 1 to this number" is not entirely true.
True that integers can be represented by repeatedly adding or subtracting the number 1,
The fact that integers can also be negative and can be obtained by repeatedly subtracting 1 from 0 or another negative integer.
The definition does not account for the fact that integers can be represented using other operations, such as multiplication or division. The integer 12 can be represented as 4 x 3 or as 24 ÷ 2.
A more accurate definition of an integer is a whole number that can be positive, negative, or zero.
Integers can be represented using addition, subtraction, multiplication, or division, and can be used to represent quantities such as counts, distances, temperatures, and other measurable quantities.
The original definition is a useful way to understand how integers can be represented using addition and subtraction, it is not a complete or entirely accurate definition of what integers are.

five rectangles, and have integer side lengths. rectangle has a width of , rectangle has a width of rectangle has a length of rectangle has a length of and rectangle has a length of if all five rectangles have the same area , what is the least possible value of ?
All five rectangles have the same area of 60, and the sum of their dimensions is:
2 + 30 + 4 + 15 + 6 + 10 + 8 + 7.5 + 10
Let the width of rectangle 1 be w1, the width of rectangle 2 be w2, and so on. We know that all five rectangles have the same area, so we can set up an equation:
[tex]w1 * l1 = w2 * l2 = w3 * l3 = w4 * l4 = w5 * l5[/tex]
We can simplify this equation by dividing both sides by w1 * l1, which gives:
[tex]1 = (w2 * l2) / (w1 * l1) = (w3 * l3) / (w1 * l1) = (w4 * l4) / (w1 * l1) = (w5 * l5) / (w1 * l1)[/tex]
Let's define a new variable x = w2 * l2 = w3 * l3 = w4 * l4 = w5 * l5. Then we have:
[tex]w1 * l1 = xw2 * l2 = xw3 * l3 = xw4 * l4 = xw5 * l5 = x[/tex]
Now we need to find the least possible value of w1 + l1 + w2 + l2 + w3 + l3 + w4 + l4 + w5 + l5. Since w1 * l1 = x, we can rewrite this as:
[tex]w1 + l1 + 4 * sqrt(x / w1) + 4 * sqrt(w1 / x)[/tex]
To find the minimum value of this expression, we can take its derivative with respect to w1, set it equal to zero, and solve for w1:
[tex]d/dw1 (w1 + l1 + 4 * sqrt(x / w1) + 4 * sqrt(w1 / x)) = 1 - 2 * sqrt(x) / w1^1.5 + 2 * sqrt(x) / w1^2.5 = 0[/tex]
Solving for w1, we get:
[tex]w1 = 2 * x^(1/4)[/tex]
Substituting this back into our expression for the sum of the rectangle dimensions, we get:
[tex]w1 + l1 + 4 * sqrt(x / w1) + 4 * sqrt(w1 / x) = 2 * x^(1/4) + 2 * x^(3/4) + 8 * (x / 2)^(1/4)[/tex]
To find the minimum value of this expression, we can take its derivative with respect to x, set it equal to zero, and solve for x:
[tex]d/dx (2 * x^(1/4) + 2 * x^(3/4) + 8 * (x / 2)^(1/4)) = 1/2 * x^(-3/4) + 3/2 * x^(1/4) + 2 / (2 * x)^(3/4) = 0[/tex]
Solving for x, we get:
x = 4
Therefore, the least possible value of w1 is:
w1 =[tex]2 * x^(1/4) = 2[/tex]
And the dimensions of the rectangles are:
Rectangle 1: 2 x 30
Rectangle 2: 4 x 15
Rectangle 3: 6 x 10
Rectangle 4: 8 x 7.5

write a equation of the line that prasses through (2,-4) and (0,-4)
Answer:
To write the equation of the line that passes through the points (2, -4) and (0, -4), we can use the point-slope form of a linear equation, which is:
y - y1 = m(x - x1)
Where (x1, y1) is one of the points on the line, and m is the slope of the line.
In this case, both points have the same y-coordinate, which means that the line is horizontal and has a slope of 0. We can choose either point to use in the equation, so let's use (2, -4):
y - (-4) = 0(x - 2)
Simplifying this equation, we get:
y + 4 = 0
y = -4
So the equation of the line that passes through the points (2, -4) and (0, -4) is y = -4, which is a horizontal line at y-coordinate -4.

—————-
The actual amount of drink made for the third batch, however, was only 8 liters. This implies that the third batch's recipe contained less pineapple.
How to calculate the actual amount of drink?We are told that each liter of pineapple juice yields the same amount of drink. This is referred to as the "r" ratio. Then:
r = d/p
We can use the provided data to get a table of r values shown in below image form.
The ratio for the first two data points is the same, but it is different for the third. This suggests the drink's recipe changed between the second and third batches.
We can calculate the ratio using the first two data points:
r = d/p = 2/1 = 6/3
So the ratio is 2, which means that we obtain 2 liters of drink for every liter of pineapple juice.
This ratio can be used to calculate the estimated amount of drink for the third batch:
d = r*p = 25 = 10
The actual amount of drink made for the third batch, however, was only 8 liters. This implies that the third batch's recipe contained less pineapple.

as part of their quality assurance program, a cell phone manufacturer inspects the display on each phone selected through random sampling to verify that the screen displays all colors with the brilliance their customers have come to expect. each phone in a sample is turned on, run through a self-test procedure, and classified as either acceptable or unacceptable based on its test performance. suppose 30 phones are randomly tested each day for seven days, and the average daily proportion of unacceptable phones is found to be 0.01. what lower and upper control limits should the manufacturer actually use in the resulting control chart?
The lower and upper control limits that the manufacturer should use in the resulting control chart are LCL = 0.023,UCL = 0.043
To calculate the lower and upper control limits for the control chart, we need to use the following formula:
Lower control limit (LCL) = average proportion of defects - 3 x square root of [(average proportion of defects x (1 - average proportion of defects)) / sample size]
Upper control limit (UCL) = average proportion of defects + 3 x square root of [(average proportion of defects x (1 - average proportion of defects)) / sample size]
Using the given information, we can plug in the values to get:
LCL = 0.01 - 3 x square root of [(0.01 x 0.99) / 30] = -0.023
UCL = 0.01 + 3 x square root of [(0.01 x 0.99) / 30] = 0.043
However, since control limits cannot be negative, the lower control limit should be set to zero.

The manufacturer should use control limits of 0 for the lower limit and 0.136 for the upper limit in their control chart for monitoring the proportion of unacceptable phones in their quality assurance program.
Determine the lower and upper control limits for the manufacturer's control chart, we first need to calculate the standard deviation of the proportion of unacceptable phones based on the given information.
To do this, we can use the formula:
[tex]Standard deviation = \sqrt(p\times(1-p)/n)[/tex]
p is the proportion of unacceptable phones (0.01), and n is the sample size (30 phones per day for 7 days = 210 total phones).
Plugging in these values, we get:
[tex]Standard deviation = \sqrt(0.01\times(1-0.01)/210) = 0.042[/tex]
Next, we can use this standard deviation to calculate the control limits. The lower control limit (LCL) is given by:
[tex][tex]LCL = p - 3\times\sqrt(p\times(1-p)/n)[/tex][/tex]
and the upper control limit (UCL) is given by:
[tex]UCL = p + 3\times\sqrt(p\times(1-p)/n)[/tex]
Plugging in our values, we get:
[tex]LCL = 0.01 - 3\times0.042 = -0.075[/tex]
[tex]UCL = 0.01 + 3\times0.042 = 0.095[/tex]
Values don't make sense - the proportion of unacceptable phones cannot be negative, and the UCL is above 1, which is also impossible.
To correct for this, we can use the formula:
[tex]LCL = max(0, p - 3\times\sqrt(p\times(1-p)/n))[/tex]
[tex]UCL = min(1, p + 3\times\sqrt(p\times(1-p)/n))[/tex]
This ensures that the control limits are within the range of possible values for the proportion of unacceptable phones.
Plugging in our values with this formula, we get:
[tex]LCL = max(0, 0.01 - 3\times0.042) = 0[/tex]
[tex]UCL = min(1, 0.01 + 3\times0.042) = 0.136[/tex]

350 - x - (x + 50)
Simplifying this expression, we get:
300 - 2x
Next, the customer makes a deposit of $75, so we can add this to the current balance:
75 + 300 - 2x
So, we have
375 - 2x
Hence, the expression is 375 - 2x

Mambo is 25 years old and currently earns R5595 per month. She wants to retire at age 65 and
wishes to earn the equivalent amount (same buying power) which she currently enjoys. Inflation is
expected to remain at 6% pa until retirement. A bank is prepared to offer Mambo 7%
pa compounded monthly on any savings until she retires. Furthermore Mambo believes that she
can earn 5% pa compounded monthly once she has retired. She expects to receive a monthly
annuity once on retirement and expects to be on retirement for 15 years. How much does Mambo
need to save per month to enjoy the equivalent retirement benefits?
Question 18
Mambo needs to save R2,322.06 per month to reach her retirement goal of R1,000,000 in 40 years, assuming an annual interest rate of 8% compounded monthly.
Using the formula for the future value of an annuity, we can solve for the monthly payment Mambo needs to make:
[tex]FV = P * [(1 + r/n)^{(nt)} - 1]/(r/n)[/tex]
where FV is the future value, P is the monthly payment, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years.
Given that Mambo has 40 years until retirement, and the interest rate is 8% per year compounded monthly, we can substitute these values into the formula:
[tex]FV = 1,000,000 \\P = ?\\r = 0.08\\n = 12\\t = 40 \\1,000,000 = P * [(1 + 0.08/12)^(12*40) - 1]/(0.08/12)[/tex]
Solving for P, we get:
P = 2,322.06

The length of the side b for the right triangle ABC is equal to 5.276, and the measures of angle A and B are 64 and 26 to the nearest degree using the sine rule.
What is the sine ruleThe sine rule is a relationship between the size of an angle in a triangle and the opposing side.
The side length b is derived using the Pythagoras rule as follows:
b = √(12.2² - 11²)
b = 5.276
Using the sine rule;
12.2/sin90 = 11/sinA
A = sin⁻¹(11 × sin90)/12.2 {cross multiplication}
A = 64.4
12.2/sin90 = 5.3/sinB
B = sin⁻¹(5.276 × sin90)/12.2 {cross multiplication}
B = 25.6
Therefore, the length of the side b for the right triangle ABC is equal to 5.276, and the measures of angle A and B are 64 and 26 to the nearest degree using the sine rule.

Last Friday, AT&T closed at $41.68. AT&T pays an annual dividend of $1.98. Calculate the dividend yield
Answer: The dividend yield is the annual dividend payment divided by the stock's current market price, expressed as a percentage.
Dividend yield = (Annual dividend payment / Stock's current market price) x 100%
In this case:
Annual dividend payment = $1.98
Stock's current market price = $41.68
Dividend yield = ($1.98 / $41.68) x 100% = 4.75%
Therefore, the dividend yield for AT&T is 4.75%.

What is circumference of a circle?The circumference of a circle is the length of the 360 degree arc of that circle. Therefore the sum of the arc on a circumference of a circle is 360°
Therefore ,
8x-10+ 6x + 10x+10 = 360
24x -10+10 = 360
24x = 360
divide both sides by 24
x = 360/24
x = 15
therefore the value of x is 15
Arc PQ = 8x -10
substitute 15 for x
ArcPQ = 8×15-10
= 120-10
= 110°
therefore the value of arc PQ is 110°
