On solving the provided question, we can say that Probability(x>11) = 1 - P(x[tex]\leq 11[/tex])\ = 0.9645 and Probability(5<x<9) = P(x<9) - P(x<5) = 0.0101 and P(x<9) = 0.0106

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

Probability(x>11) = 1 - P(x[tex]\leq 11[/tex])\

= 0.9645

Probability(5<x<9) = P(x<9) - P(x<5)

= 0.0101

The actual distance between two cities that are 3 7/8 inches apart on the map is 279 miles.

Step-by-step explanation:

To find the actual distance between two cities, we need to convert the distance on the map to miles. The scale of the map is 3/4 inch equals 72 miles, which means 1 inch on the map is equal to 72/3=24 miles.

So, the actual distance between two cities on the map that are 3 7/8 inches apart is 24 * 3 7/8 = 279 miles.

A word problem for the given expression is the division of 3/4 cups of juice among two friends equally.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given is an expression [tex]\frac{3}{4}[/tex] × [tex]\frac{1}{2}[/tex].

Suppose that there are 3/4 cups of juice available.

The number of trains that can accommodate 2 passengers is x = 32, the number of trains that can accommodate 3 passengers is y = 1, and the number of trains that can accommodate 5 passengers is z = -11.

It is represented by an equal sign (=) and consists of variables, numbers, and mathematical operations. Equations are used to describe relationships between different quantities and can be solved to find unknown values. For example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving 2x = 4, and then dividing both sides by 2, giving x = 2.

Let x, y and z be the number of trains that can accommodate 2 passengers, 3 passengers and 5 passengers, respectively.

From the information given, we have:

x + y + z = 20 (the total number of trains)

2x + 3y + 5z = 64 (the total number of passengers)

We also know that 10 trains were used during market day:

3 of the x trains, 2 of the y trains and 4 of the z trains.

So, we have:

2x + y + 5z = 10

Solving these three equations simultaneously, we can find the values of x, y and z:

Subtracting the first equation from the third equation:

0 + y + 4z = -10

y + 4z = -10

Subtracting 2 times the first equation from the second equation:

-x + 3y + 4z = 32

y + 4z = 42

Subtracting the last two equations:

x = 32

Substituting the value of x back into the first equation:

32 + y + z = 20

y + z = -12

Substituting the value of y and z back into the third equation:

2x + y + 5z = 10

64 + y + 5z = 10

y + 5z = -54

Solving these two equations simultaneously, we can find the values of y and z:

Subtracting the second equation from the last equation:

4z = -44

z = -11

Substituting the value of z back into the second equation:

y + 5z = -54

y - 55 = -54

y = 1

Therefore, the number of trains that can accommodate 2 passengers is x = 32, the number of trains that can accommodate 3 passengers is y = 1, and the number of trains that can accommodate 5 passengers is z = -11.

Step-by-step explanation:

When dealing with operations with exponents and multiplication, the exponent operations always come first.  So while the exponent 9 is correct for the answer, 4 is incorrect.

For example, if you were to solve each operation and eliminate every exponent, you would have

2^4*2^5=16*32=512 which is the same as 2^9=512.

As you can see, the exponent operation must come before the multiplication.

The range of the function, given the graph of a relation, can be found to be −2 ≤ y ≤ 7 .

Graphs can be used to determine a function's domain and range. The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The y-axis on a graph represents the possible output values, or range.

The range here would therefore be the y - values that the relations fall within. The lowest y - value is - 2 as no relation goes below this. The highest y - value is 7.

Hi there, here's your answer:

The general formula of a circle:

[tex](x-h)^{2} +(y-k)^{2}=r^2\\[/tex]

Where the ordered pair (h, k) is the center of the circle.

Given (h, k) = (-6, -2)

We also have that the circle passes through a point (7, 12)

Which means that (7, 12) lies on the circumference of the circle.

Let this be labelled as [tex](x_{1}, y_{1})[/tex]

Since this point lies on the circumference of the circle, it must satisfy the equation when substituted in for (x, y).

Thus, we substitute [tex]x_{1}[/tex] for x and [tex]y_{1}[/tex] for y.

We get the final equation to be:

The study of numbers and their variable, as well as in out environment, architecture, and both real and imagined places, are all covered in the mathematics curriculum. A function range illustrates visually how the amounts of the inputs and the corresponding outputs for each are related. Simply stated, a function is a set of inputs that, when combined, produce specific outputs for each input. Each position is given a locale, region, or range.

Here,

Rolle's Theorem can be applied to $f(x) = x^2 - 3$ on the interval [-2, 2]. This is because f(x) satisfies the following conditions of Rolle's Theorem:

1 ) f(x) is continuous on the interval [-2, 2]

2 ) f(x) is differentiable on the interval (-2, 2)

3)  f(-2) = 1 and f(2) = 1

Since f(-2) = f(2), there must exist at least one point c in the interval (-2, 2) such that f'(c) = 0.

Taking the derivative of f(x) with respect to x, we get f'(x) = 2x. Setting f'(c) = 0, we have:

2c = 0

Solving for c, we get c = 0.

Therefore, the value of c for which f'(c) = 0 in the interval [-2, 2] is c = 0.

By using the Pythagorean theorem, we can write:

d² + h² = s²

Simplifying and solving for d, we get:

d² = s²-h²

d = √(s²-h² )

Let's call the length of the cord "L". Then, we can write:

d² + L² = s²

Differentiating both sides with respect to time (t), we get:

2d (dd/dt) + 2L (dL/dt) = 2s (ds/dt)

We want to find (dL/dt) when L = s and d = √(s²-h² )

(dd/dt) = 0 as the height of the kite above the child's hand level is constant.

(dL/dt) = (s(ds/dt) - d (dd/dt)) / L

Step-by-step explanation:

The given arithmetic series is:

From inspection of the given series, the first term is 24.

The common difference is the difference between consecutive terms.

Therefore, the common difference of the given series is -8 as each term is 8 less than the previous term.

[tex]\boxed{\begin{minipage}{7.3 cm}\underline{Sum of the first $n$ terms of an arithmetic series}\\\\$S_n=\dfrac{1}{2}n[2a+(n-1)d]$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $d$ is the common difference.\\ \phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

To find the sum of the first 18 terms of the given series, substitute a = 24, d = -8 and n = 18 into the sum formula.

[tex]\implies S_{18}=\dfrac{1}{2}(18)\left[2(24)+(18-1)(-8)\right][/tex]

[tex]\implies S_{18}=9\left[48+(17)(-8)\right][/tex]

Therefore, the sum of the first 18 terms of the given arithmetic series is -792.

The missing amounts are a) $79,000, b) $22,000, c) $51,000, d) $15,000  and  e) $6,000.

We have,

The theory used in this question is the basic accounting equation which states that Assets = Liabilities + Equity.

This equation can be used to determine the missing amounts in the summaries of Greene's Goods and Solar Enterprises.

Step 1: Start with the beginning of year data for Greene's Goods. We know that the Total Assets = $110,000, Total Liabilities = $85,000 and that the Total Owner's Equity is missing. We can use the basic accounting equation to solve for Total Owner's Equity.

Assets = Liabilities + Equity

110,000 = 85,000 + Equity

Equity = 25,000

Step 2: Now look at the ending of year data for Solar Enterprises. We know that the Total Assets = $180,000, Total Liabilities = $50,000 and that the Total Owner's Equity is missing. We can use the basic accounting equation to solve for Total Owner's Equity.

Assets = Liabilities + Equity

180,000 = 50,000 + Equity

Equity = 130,000

Step 3: Lastly, look at the changes in owner's equity for each proprietorship. For Greene's Goods, we know that Additional Investment = $7,000 and Drawings = $37,000. We can use the basic accounting equation to solve for the missing amount.

Change in Equity = Additional Investment + Drawings

Change in Equity = 7000 + 37000

Change in Equity = $44,000

For Solar Enterprises, we know that Additional Investment

= $25,000 and Drawings = $15,000.

We can use the basic accounting equation to solve for the missing amount.

Change in Equity = Additional Investment + Drawings

Change in Equity = 25000 + 15000

Change in Equity = $40,000

Therefore, the missing amounts are:

a) $79,000
