Probability of red = \(\frac{4}{10}\) , blue = \(\frac{5}{10}\) , green = \(\frac{1}{10}\).

Meaning of probability :

Probability is calculation of how likely some event will happen. Whenever we are not sure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are going to happen.

The analysis of events governed by probability is called statistics.

According to the given information :

Red section = \(\frac{2}{5}\)

multiply numerator and denominator by \(2\) we get

Red section = \(\frac{4}{10}\)

 Blue section = \(\frac{1}{2}\)

 multiply numerator and denominator by \(5\) we get

 Blue section = \(\frac{5}{10}\)

 Green section = \(1\)- Red section - Blue section

 Green section =\(1-\frac{4}{10} -\frac{5}{10}\)

  Green section = \(\frac{1}{10}\)

Therefore Probability of red = \(\frac{4}{10}\) , blue = \(\frac{5}{10}\) , green = \(\frac{1}{10}\).

AB=72×5.2/6=62.4

Given that ΔSCD and ΔSAB are similar triangles, the distance across the lake is: AB = 62.4 m.

Similar triangles possess corresponding side lengths that are proportional to each other, which means the ratio of their corresponding sides are equal.

Thus, since ΔSCD is similar to ΔSAB, therefore:

The product of a fraction between 0 and 1 and a whole or mixed number is always less than the whole number or mixed number.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

The product of the whole number by 1 will be the same number.

For example 4 × 1 = 4

If we multiply the whole number by greater than 1 then the result will be increased.

For example 4 × 1.2 = 4.8

But if we multiply the whole number by less than 1 then the value is going to be decreased.

Answer:

The family of all prime numbers such that \(a^{2} + b^{2} + c^{2} -1\) is a perfect square is represented by the following solution:

\(a\) is an arbitrary prime number. (1)

\(b = \sqrt{1 + 2\cdot a \cdot c}\) (2)

\(c\) is another arbitrary prime number. (3)

Step-by-step explanation:

From Algebra we know that a second order polynomial is a perfect square if and only if \((x+y)^{2} = x^{2} + 2\cdot x\cdot y + y^{2}\). From statement, we must fulfill the following identity:

\(a^{2} + b^{2} + c^{2} - 1 = x^{2} + 2\cdot x\cdot y + y^{2}\)

By Associative and Commutative properties, we can reorganize the expression as follows:

\(a^{2} + (b^{2}-1) + c^{2} = x^{2} + 2\cdot x \cdot y + y^{2}\) (1)

Then, we have the following system of equations:

\(x = a\) (2)

\((b^{2}-1) = 2\cdot x\cdot y\) (3)

\(y = c\) (4)

By (2) and (4) in (3), we have the following expression:

\((b^{2} - 1) = 2\cdot a \cdot c\)

\(b^{2} = 1 + 2\cdot a \cdot c\)

\(b = \sqrt{1 + 2\cdot a\cdot c}\)

From Number Theory, we remember that a number is prime if and only if is divisible both by 1 and by itself. Then, \(a, b, c > 1\). If \(a\), \(b\) and \(c\) are prime numbers, then  \(2\cdot a\cdot c\) must be an even composite number, which means that \(a\) and \(c\) can be either both odd numbers or a even number and a odd number. In the family of prime numbers, the only even number is 2.

In addition, \(b\) must be a natural number, which means that:

\(1 + 2\cdot a\cdot c \ge 4\)

\(2\cdot a \cdot c \ge 3\)

\(a\cdot c \ge \frac{3}{2}\)

But the lowest possible product made by two prime numbers is \(2^{2} = 4\). Hence, \(a\cdot c \ge 4\).

The family of all prime numbers such that \(a^{2} + b^{2} + c^{2} -1\) is a perfect square is represented by the following solution:

\(a\) is an arbitrary prime number. (1)

\(b = \sqrt{1 + 2\cdot a \cdot c}\) (2)

\(c\) is another arbitrary prime number. (3)

\(b = \sqrt{1 + 2\cdot (2)\cdot (2)}\)

\(b = 3\)

Reason: Since their scale factor is 2 / 3, meaning that the object 2 / 3 of the other same object, so the volume also 2 / 3 of the other object

The value of m that satisfies the equation -3 + m = 9 is m = 12.

To solve the equation -3 + m = 9, we can isolate the variable m by moving the constant term -3 to the other side of the equation.

-3 + m = 9

To move -3 to the other side, we can add 3 to both sides of the equation:

-3 + 3 + m = 9 + 3

Simplifying, we have:

m = 12

Therefore, the value of m that satisfies the equation -3 + m = 9 is m = 12.

The coordinates of the vertex of the parabola are (3, -7). The focus of the parabola is located at (3, -3). The equation of the directrix is y = -11.

The given equation of the parabola is in the form (x - h)^2 = 4p(y - k), where (h, k) represents the vertex and p represents the distance between the vertex and the focus/directrix.

Comparing the given equation with the standard form, we can see that the vertex is at (3, -7).

The coefficient 4p in this case is 16, so p = 4. Since the parabola opens upward, the focus will be p units above the vertex. Therefore, the focus is located at (3, -7 + 4) = (3, -3).

To find the directrix, we need to consider the distance p below the vertex. Since the parabola opens upward, the directrix will be p units below the vertex. Hence, the equation of the directrix is y = -7 - 4 = -11.

In summary, the coordinates of the vertex are (3, -7), the focus is located at (3, -3), and the equation of the directrix is y = -11.

The point charges placed 0.500 m apart are 10.4 nC and 43.9 nC. Then, the electric field halfway between these charges will be -4824 N/C.

The physical field that surrounds particles with an electrical charge is called an electric field. All other charged particles in the field are affected by it, either being attracted to it or being repelled by it.

The electric field because of a point charge q is written as \(E=\frac{kq}{r^2}\)

Positive point charges cause the electric field to point away from the point, whereas negative point charges cause the electric field to point in the direction of the point. Then, the electric field of the midpoint p in the diagram is written as,

\(\begin{aligned}E_p&=\mathrm{\frac{k(10.4\;nC)}{(0.25\;m)^2}-\frac{k(43.9\;nC)}{(0.25\;m)^2}}\\&=\mathrm{\frac{k(10.4-43.9)\times10^{-9}\;C}{(0.25\;m)^2}}\\&=-\mathrm{\frac{9\times 10^9\;Nm^2/C^2\times 33.5\times10^{-9}\;C}{(0.25\;m)^2}}\\&=-\mathrm{4824\;N/C}\end{aligned}\)

In set-builder notation, the same set can be expressed as {x|x (N and 4<x<10)}, which reads as "the set of all x such that x is a natural number and 4 < x < 10."

How to solve the question?

a. The set of natural odd numbers greater than 2, but less than 11 can be expressed using the roster method as {3, 5, 7, 9}. The set includes all the odd natural numbers between 2 and 11, excluding the endpoints, since 2 is not odd, and 11 is not less than 11.

b. The set {x|x (N and 4<x<10)} can be expressed using the roster method as {5, 6, 7, 8, 9}. The set includes all the natural numbers greater than 4 and less than 10, since x is a natural number (N) and satisfies the condition 4 < x < 10.

In set-builder notation, the same set can be expressed as {x|x (N and 4<x<10)}, which reads as "the set of all x such that x is a natural number and 4 < x < 10." The vertical bar separates the description of the elements of the set (the condition) from the set itself.

The roster method and set-builder notation are both ways of describing sets, but the roster method lists all the elements of a set, while the set-builder notation describes the properties or conditions that define the set. Both methods are useful in different situations and depend on the specific context and the purpose of the set description.

There is no sufficient evidence to conclude that the mean price in Providence for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is less than the population mean of $32.48

Step-by-step explanation:

From the question we are told that

   The mean price of   is  \(\mu = \$ 32.48\)

   The  sample size is n  =  56  

    The sample mean is  \(\=  x  =  \$30.15\)

     The standard deviation is  \(\sigma =  \$12\)

The  null hypothesis is   \(H_o  :  \mu =  32.48\)          

The alternative  hypothesis is   \(H_a  :  \mu  <  32.48\)

Generally the test statistic is mathematically represented as

       \(t =  \frac{\= x  - \mu }{\frac{\sigma }{\sqrt{n} } }\)

=>    \(t =  \frac{30.15  - 32.48 }{\frac{12 }{\sqrt{60} } }\)

=>    \(t  =  -1.504\)

Generally the p-value  is mathematically represented as

      \(p-value  =  P (t < -1.504 )\)

From the z-table  

    \(P(t <  -1.504) =   0.066291\)

So  

    \(p-value  = 0.066291 \)

From the value we obtain we see that

The area of the rectangle, 70 ft², is equal to the length, 10 ft, times the width, w.

So, to find w, we can divide the area by the length.

w = 70 / 10

w = 7

The width is equal to 7 feet.

We can check this by multiplying the given length by the width that we've calculated to see if the area is equal to 70 feet².

10 · 7 = A

70 = A

We need to find a pair that adds up to the co-eff of x which is (-1)

Factors :(2,-3)

2 - 3 = -1

so, 2x² - x - 3 = 0 can be written as:

2x² + 2x - 3x - 3 = 0

⇒ 2x(x + 1) -3(x + 1) = 0

⇒ (2x - 3)(x + 1) = 0

⇒ 2x - 3 = 0 or

x + 1 = 0

⇒ 2x = 3 or x = -1
