Answer:

interquartile range = 6

Step-by-step explanation:

the interquartile range is the difference between the upper quartile Q₃ and the lower quartile Q₁

Q₃ is the value at the right side of the box, that is 86

Q₁ is the value at the left side of the box, that is 80

interquartile range = Q₃ - Q₁ = 86 - 80 = 6

The probability that none of the 4 lightbulbs in the sample are defective is 805/1763 as a reduced fraction.

Let's first calculate the total number of ways to choose 4 lightbulbs from 24:

24 choose 4 = (24!)/(4! * 20!) = 10,626

Probability that all 4 lightbulbs in the sample are defective:

There are 4 defective lightbulbs in the shipment, so the number of ways to choose all 4 from the 24 is:

4 choose 4 = 1

So, the probability that all 4 lightbulbs in the sample are defective is:

1/10,626 = 1/5313

Therefore, the probability that all 4 lightbulbs in the sample are defective is 1/5313 as a reduced fraction.

Probability that none of the 4 lightbulbs in the sample are defective:

There are 4 defective lightbulbs in the shipment, so the number of ways to choose 4 non-defective bulbs from the remaining 20 is:

20 choose 4 = (20!)/(4! * 16!) = 4,845

So, the probability that none of the 4 lightbulbs in the sample are defective is:

4,845/10,626 = 805/1763

Since magnesium has a larger volume than nickel, it will displace more water from an overflow can.

We need to compare their volumes.

We can use the formula:

Density = mass / volume

To solve for volume, we rearrange the formula:

Volume = mass / density

For nickel:

Volume = 130g / 8.90 g/cm³ = 14.61 cm³

For magnesium:

Volume = 60g / 1.78 g/cm³ = 33.71 cm³

Answer:

To differentiate the implicit function sin(y) + x^2y^3 - cos(x) = 2y with respect to x, we will use the chain rule and product rule.

First, we will take the derivative of both sides of the equation with respect to x:

d/dx [sin(y) + x^2y^3 - cos(x)] = d/dx [2y]

Next, we will differentiate each term on the left side of the equation:

cos(x) - 2xy^2 dx/dx + 3x^2y^2 + sin(y) dy/dx = 2 dy/dx

We can simplify this equation by moving all the terms involving dy/dx to the left side:

cos(x) - 2xy^2 - 2 dy/dx sin(y) = dy/dx [2 - sin(y)]

Now we can solve for dy/dx by isolating it on one side of the equation:

dy/dx [2 - sin(y)] = cos(x) - 2xy^2

dy/dx = (cos(x) - 2xy^2) / [2 - sin(y)]

Therefore, the derivative of the implicit function sin(y) + x^2y^3 - cos(x) = 2y with respect to x is:

dy/dx = (cos(x) - 2xy^2) / [2 - sin(y)]

The missing data value in the project is 25.5.

Range is a statistical measure that represents the difference between the highest and lowest values in a dataset. It is calculated by subtracting the smallest value in the dataset from the largest value.

To find the missing data value, we need to use the given range and the known data values.

The range is the difference between the highest and lowest values in the data set. So, if we sort the given data values in increasing order, we have:

11, 15, 15, 22, 29, 31

The range is 33, which means that:

highest value - lowest value = 33

31 - 11 = 33

So, the missing data value must be between 22 and 29 (since those are the values that are next to each other in the sorted list). To find the exact value, we can take the average of 22 and 29:

(22 + 29) / 2 = 25.5

Therefore, the missing data value is 25.5.

in 2 years, Leah will be exactly twice as old as she was four years ago. Therefore, the answer is 2 years.

Let's start by setting up an equation based on the given information.

Let Leah's current age be represented by "x". Then, we know that:

x = 3(x-4)

Expanding the right side of the equation:

x = 3x - 12

Bringing the "x" term to the left side and simplifying:

2x = 12

x = 6

So Leah is currently 6 years old. Now we want to find out how many years it will take for her to be exactly twice as old as she was four years ago. Let's represent this number of years as "y". Then we can set up another equation:

6 + y = 2(6 - 4 + y)

Simplifying:

6 + y = 2(2 + y)

6 + y = 4 + 2y

2 = y

So in 2 years, Leah will be exactly twice as old as she was four years ago. Therefore, the answer is 2 years.

With given compound interest, it will take approximately 31 years and 5 months to pay off the loan.

What is Compound interest?

Compound interest is computed on both the starting principal and the accrued interest from prior periods. In other words, it is the interest gained not just on the principle amount but also on any past interest earned.

Now,

Using the given formula:

N = (-log(1 - i * A / P)) / (log(1 + i))

where i = 0.0025 (0.25% monthly interest rate), A = $70,000, and P = $250

N = (-log(1 - 0.0025 * 70000 / 250)) / (log(1 + 0.0025))

N = (-log(1 - 175)) / (log(1.0025))

N = (-log(0.9883)) / (0.0025)

N = 376.48

Rounding up to the nearest whole number, it will take 377 months to pay off the loan.

Therefore, it will take approximately 31 years and 5 months to pay off the loan.

Finally, we can multiply 4 by 1.095^x to get the simplified function:

Therefore, the system of equations that could be used to determine the number of liters of Drink A made and the number of liters of Drink B made is.

[tex]0.1x + 0.2y = 70[/tex]

[tex]y = 3x[/tex]

Where x represents the number of liters of Drink B made, and y represents the number of liters of Drink A made.

Let's define the variables as follows:

Let x be the number of liters of Drink B produced.

Since the company produced 3 times as many liters of Drink A as liters of Drink B, let y be the number of liters of Drink A produced, so y = 3x.

Now, let's write the system of equations:

The total amount of real fruit juice used is 70 liters, so we can write:

[tex]0.1x + 0.2y = 70[/tex]

Substituting y = 3x into the above equation, we get:

[tex]0.1x + 0.2(3x) = 70[/tex]

Simplifying the equation:

[tex]0.1x + 0.6x = 70[/tex]

[tex]0.7x = 70[/tex]

[tex]x = 100[/tex]

So, the company made 100 liters of Drink B and 3 times as many liters of Drink A, or 300 liters of Drink A.

Therefore, the system of equations that could be used to determine the number of liters of Drink A made and the number of liters of Drink B made is:

[tex]0.1x + 0.2y = 70[/tex]

The amount received from loans as a number in millions is 242,700 million rand.

Deducing value A requires computation of collective income sources, for which the following summation suffices:

Total Income = Tax + Loans + ASC + QP + Other income + Non-tax income = 1370 + 242.7 + 180.3 + 31.5 + A + 0 = 1825.5 + A

In this context, it follows that A amounts to (1825.5 - 1370 - 242.7 - 180.3 - 31.5) = 0 million rand.

Conversely determining missing value B necessitates subtraction of total expenditure from accumulated revenue, giving rise to the subsequent formula:

Total Income - Total Expenditure = B

The factored form of the quadratic function f(x), which has roots of 3 and 7, is as follows:

f(x) = a(x - 3)(x - 7) (x - 7) where "a" stands for a fixed coefficient.

We can utilise the point (1, 12) through which the function passes to determine the value of "a"

12 = a(1 - 3) (1 - 3)(1 - 7)

12 = -24a

a = -1/2

The standard form equation of a circle whose diameter endpoints are  (-3,4) (2,1) is [tex](x - (-0.5))^2 + (y - 2.5)^2[/tex] = 6.5

The general form of the equation of a circle is (x - h)² + (y - k)² = r², where (h, k) represents the center of the circle and r represents the radius. This equation is derived using the Pythagorean theorem, which states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse. By setting (x - h)² and (y - k)² equal to r² and then combining the two equations, we get the standard form equation of a circle.

The center of the circle lies in the middle of the diameter, so we find the midpoint of the end points:

[tex](\frac{-3+2}{2} , \frac{4+1}{2} )[/tex] = (-0.5, 2.5)

And radius of the circle is half of the diameter, which is:
