A charity needs to report its typical donations received. The following is a list of the donations from one week. A histogram is provided to display the data.
10, 11, 35, 39, 40, 42, 42, 45, 49, 49, 51, 51, 52, 53, 53, 54, 56, 59
A graph titled Donations to Charity in Dollars. The x-axis is labeled 10 to 19, 20 to 29, 30 to 39, 40 to 49, and 50 to 59. The y-axis is labeled Frequency. There is a shaded bar up to 2 above 10 to 19, up to 2 above 30 to 39, up to 6 above 40 to 49, and up to 8 above 50 to 59. There is no shaded bar above 20 to 29.
Which measure of variability should the charity use to accurately represent the data? Explain your answer.
The range of 13 is the most accurate to use, since the data is skewed.
The IQR of 49 is the most accurate to use to show that they need more money.
The range of 49 is the most accurate to use to show that they have plenty of money.
The IQR of 13 is the most accurate to use, since the data is skewed.
Answers
The IQR (Interquartile Range) of 13 is the most accurate measure of variability to use in this scenario, since the data is skewed and contains outliers.
What is data?
Data refers to any information, facts, or statistics that are collected, stored, and analyzed for a specific purpose. Data can take many forms, such as text, numbers, images, audio, and video, and can be generated from a variety of sources, including sensors, surveys, transactions, and social media.
Here,
The range, which is the difference between the maximum and minimum values (59 - 10 = 49), may be affected by extreme values that are far from the majority of the data. In this case, the donations of 10 and 59 are outliers and may distort the range as a measure of variability.
On the other hand, the IQR, which is the range of the middle 50% of the data (the difference between the third quartile and the first quartile), is a robust measure of variability that is not sensitive to outliers. The IQR in this case is calculated as follows:
First quartile \((Q_1)\) = 42
Third quartile \((Q_3)\) = 53
\(IQR = Q_3 - Q_1 = 53 - 42 = 11\)
Therefore, the IQR of 13 is a more accurate measure of variability to use in this scenario, as it represents the spread of the majority of the data and is not influenced by the extreme values.

Answers
The lengths of the major and minor axis are 4√6 and 4√3.
What is Major and Minor Axis?A point on a curve is described by an ellipse if its location is such that the sum of the distances between its two focal points is a constant.
(x−h)²/ b² +(y- k)² /a² = 1
Given:
(x−3)²/ 27+(y+4)² /45=1
The above equation can be compared to the standard equation of an ellipse
(x−h)²/ b² +(y- k)² /a² = 1
where, (h, k) = coordinates of the center of the ellipse
a = length of the semi major axis
b = length of the semi minor axis
By comparison, we have;
(h, k) = (3, -4)
a = √(24) = 2 x√6
b = √(12) = 2 x√3
and, length of the major axis = 2a
length of the minor axis = 2b
Thus, The length of the major axis is

Show workings to support your answer.
Answers
Answer:
The answer is Yes .. Ron is correct
Step-by-step explanation:
This is because each side of the outer square is 2 units summing up to 8 units. So dividing each into two equal parts give 1 unit each.
Each side of the inner square divides the outer square into two making each side 1 unit.
The inner square thus takes 1 unit for it's side summing the perimeter to 4 units.
(Chapter 14) If f(x,y) has two local maximal, then f must have a local minimum.TrueFalse
Answers
It is true that the existence of two local maxima does not guarantee the presence of a local minimum. It is possible for a function to have multiple local maxima and no local minimum.
For example, consider the function f(x,y) = x^4 - 4x^2 + y^2. This function has two local maxima at (2,0) and (-2,0), but no local minimum. Therefore, the statement "if f(x,y) has two local maximal, then f must have a local minimum" is false. The presence or absence of local maxima and minima depends on the behavior of the function in the immediate vicinity of a point, and cannot be determined solely based on the number of local maxima. It is possible for a function to have an infinite number of local maxima and minima, or none at all. Therefore, it is important to carefully analyze the behavior of a function in order to determine the presence or absence of local extrema.

Solution:
Given:
\(w(x)=-(3x)^{\frac{1}{2}}-4\)Rewriting the function, by applying the law of fractional exponents,
\(a^{\frac{1}{2}}=\sqrt{a}\)Hence,
\(\begin{gathered} w(x)=-(3x)^{\frac{1}{2}}-4 \\ w(x)=-\sqrt{3x}-4 \end{gathered}\)The domain of a function is the set of all input values that make the function defined.
The function is undefined when the value of x under the root sign is less than zero because the square root of a negative number is complex.
Hence, the domain exists when x has a value greater than or equal to 0.
Therefore, the domain is;
\(Domain:x\ge0\)The range of a function is the set of all output values that makes the function defined.

to double, you need another $4000
number of years = 4000/200 = 20
annual interest = .05(4000) = 200

Janelle is considering two options for saving money. One option earns simple interest while the other option earns interest compounded monthly. If there are no additional deposits or withdraws, how much more will Janelle earn with the compound interest option? Assume Janelle deposits $3,000 at 3% interest for 7 years for both options
Answers
Janelle will earn approximately 729.19 more with the compound interest option compared to the simple interest option over a period of 7 years.
The amount Janelle will earn with the compound interest option can be calculated using the formula for compound interest:
\(A = P(1 + r/n)^{(nt)}\)
Where:
A is the total amount after interest has been compounded
P is the principal amount (the initial deposit)
r is the annual interest rate (expressed as a decimal)
n is the number of times interest is compounded per year
t is the number of years
In this case, Janelle deposits 3,000 at an interest rate of 3% for 7 years. We'll compare the simple interest and compound interest options.
For the simple interest option, the interest is calculated using the formula:
I = P * r * t
Where:
I is the total interest earned
Using the given values, we can calculate the interest earned with simple interest:
I = 3000 * 0.03 * 7
I = 630
Now, let's calculate the total amount earned with the compound interest option.
Since the interest is compounded monthly, the interest rate needs to be divided by 12 and the number of years needs to be multiplied by 12:
r = 0.03/12
t = 7 * 12
Using these values, we can calculate the total amount with compound interest:
\(A = 3000 * (1 + 0.03/12)^{(7*12)}\)
A ≈ 3,729.19
To find out how much more Janelle will earn with the compound interest option, we subtract the initial deposit from the total amount with compound interest:
Difference = A - P
Difference = 3,729.19 - 3,000
Difference ≈ 729.19
Therefore, Janelle will earn approximately 729.19 more with the compound interest option compared to the simple interest option over a period of 7 years.

Answers
The equation for the indifference curve using the values A=4, alpha=2/5, and beta=3/5 is \(Y=4*(X^(2/5))*(Z^(3/5)).\)
The equation for the indifference curve represents combinations of two goods, X and Z, that provide the same level of utility or satisfaction to an individual. In this case, the values provided are A=4, alpha=2/5, and beta=3/5.
The general form of the equation for the indifference curve is given by \(Y=A*(X^alpha)*(Z^beta)\), where Y represents the level of utility, X represents the quantity of good X consumed, and Z represents the quantity of good Z consumed.
By substituting the given values, the equation for the indifference curve becomes \(Y=4*(X^(2/5))*(Z^(3/5))\). This equation shows that the level of utility, Y, is determined by the quantities of goods X and Z, with X raised to the power of 2/5 and Z raised to the power of 3/5, and multiplied by the scaling factor A=4.
Therefore, the equation for the indifference curve is \(Y=4*(X^(2/5))*(Z^(3/5))\) based on the provided values of A, alpha, and beta.

Answers
There are \(700\) children and \(1300\) adults.
What is system of linear equations?
A System of Linear Equations is when we have two or more linear equations working together.
Let \(x\) be number of children and \(y\) be number of adults.
Since \(2000\) people enter the zoo then \(x+y=2000.\)
The admission fee at a local zoo is $ \(1.50\) for children and $ \(5.00\) for adults and $\(7550.00\) collected then \(1.5x+5y=7550\).
Thus there are two linear equations to solve.
Substitute \(x=2000-y\) in \(1.5x+5y=7550.\)
\(1.5(2000-y)+5y=7550\)
\(3000-1.5y+5y=7550\)
\(3000+3.5y=7550\)
\(3.5y=7550-3000\)
\(3.5y=4550\)
\(y=\frac{4550}{3.5}\)
\(y=1300\)
So \(x=2000-y=2000-1300=700.\)
Therefore there are \(700\) children and \(1300\) adults.
