These are independent events because the likelihood of the first event has no bearing on the probability of the second event. Let V represent choosing holidaymakers from the previous summer.

Probabilities are mathematical explanations of the likelihood that an event will occur or that a proposition is true.

P(V)= (8/10)*(8/10)*(8/10)

P(V)= 512/1000

= 51.2%.

The likelihood of an event is represented by a number between 0 and 1, with 0 typically signifying impossibility and 1 typically signifying certainty.

Basic probability is governed by three primary rules: the addition rule, the multiplication rule, and the complement rule.

Scientific notation exists as a method of writing very large or very small numbers. The expression as a number in scientific notation is 2.5 × [tex]10^5[/tex], 3.5 × [tex]10^{-7[/tex], 1 × [tex]10^{-8[/tex], 3.24 × [tex]10^{17[/tex],

Utilizing scientific notation, one can express extremely big or extremely small values. When a number between 1 and 10 is multiplied by a power of 10, the result is represented in scientific notation.

To express exceedingly high numbers in a shorter manner, scientists have created a shorthand. Scientific notation is the name of this technique. The foundation of scientific notation is the base-10 powers. The coefficient is defined as the initial number, 1.23.

The guidelines for writing scientific notation.

Always start with a base of 10.

The exponent may have both positive and negative values and must be a non-zero integer.

The absolute value of the coefficient is more than or equal to 1, even though it should be less than 10.

Whole numbers, decimal numbers, positive, negative, or both can all be used as coefficients.

The mantissa represents the remaining significant digits of the number.

Step-by-step explanation:

x²-6x+9 = 0

Factor

(x-3)(x-3) = 0

x = 3

Answer:

x = 3

Step-by-step explanation:

We need to find to numbers that sum up to make -6 but their product is +9 :

-3 and -3 will do :

Now we split -6x into -3x and -3x :

x² -3x -3x + 9 = 0  

Factorise the first 2 terms:

x(x-3)

Keeping the terms inside the bracket the same as the 1st one factorise the next 2 terms :

x(x-3)-3(x-3) = 0

Keep 1 bracket and make another bracket out of the terms that are outside the brackets :

(x-3)(x-3) = 0

Using the integer rule :

a × 0 = 0

We know that one of these brackets are equal to zero :

x-3= 0

Add 3 to both sides :

x = 3

The other bracket is the same so our final answer is x = 3

Hello, and thank you for asking your question on Brainly!

This problem is basically telling is to isolate the variable g. But how are we to do so, when it's being sandwiched inside a variety of numbers and letters? The problem looks harder than it seems. But do not fret!

When you're in a trail in the woods and you get lost, the most logical thing is to do the opposite of where you just went in order to try and reach home. We can use this same analogy for math. We just try and use the opposite operation for every action that the function is being acted on!

Let be the original equation,

[tex]u=\sqrt{Ng+Q^3 }[/tex]

Looks pretty complicated right? We want to isolate the variable g, so let's get rid of this 'roof' over their heads.

To get rid of the square root, we can square both sides by two; this negates the square root, and opens up the right section of the equation.

[tex]u=\sqrt{Ng+Q^3 }[/tex]

[tex]u^2 =(\sqrt{Ng+Q^3 })^2[/tex]

[tex]u^2=Ng+Q^3[/tex]
Now, we have to make sure we get the variable g alone. Let's subtract Q cubed to the other side, we can subtract it over to get rid of it on the right hand side.

[tex]u^2=Ng+Q^3\\-Q^3 ~~~~~ -Q^3[/tex]

[tex]u^2-Q^3=Ng[/tex]
We're almost close! Now, all we have to do to isolate the variable g is to divide the whole equation by N, so the right hand side it cancels out. This is the opposite of N multiplied by g.

[tex]\frac{u^2-Q^3}{N} =g[/tex]

It wasn't so bad now, was it? I hope this helped! g is now isolated and this is the end of the problem.

Based on the calculations, the length of the zoo railroad track which does not need to be replaced is equal to 3543/8 or 442.875.

A fraction can be defined as a numerical quantity which isn't expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.

In Mathematics, a fraction comprises two (2) main parts and these include the following:

In order to determine the length of the zoo railroad track which does not need to be replaced, we would add all of the length of the zoo railroad track that need to be replaced and then subtract this value from the total length of the zoo railroad track as follows:

Length of replacement = 62/2 + 83/8 + 63/4

Note: Lowest common denominator (LCM) = 8.

Length of non-replacement = (248 + 83 + 126)/8

Length of non-replacement = 457/8

Length of replacement = 500 - 457/8

Length of replacement = (4000 - 457)/8

Length of replacement = 3543/8 or 442.875.

Two sides without an angle measurement, such as a = 6 m and b = 9 m, can be used to create an infinite number of acute triangles.

How many distinct acute triangles can we make, for instance, if our side lengths are 6 m and 9 m and our angle value ranges from 0 to 90 degrees?

Create a triangle with a 45-degree angle, sides that are 10 and 10 meters long, and a third side that can be stretched to the required length. You've constructed a triangle.

We can create a whole different Acute triangle that is identical to this one by altering the length and angle of the third side.

Never overlook picking the side angles and lengths. It's possible that you'll choose to proceed in a different way. There are an infinite amount of distinct triangles that can be created with the same angles.

As a result, we can make an infinite number of acute triangles using a single angle and a single side length.

The slope between the two given points (4,5) as well as (1,8) is -1.

A line's slope is a measure of its steepness & direction.

The slope of a line is defined as a change in y coordinate in relation to a change in x coordinate.

        m = Δy/Δx

        where,m is the slope

Now, as per the stated question;

The slope of a line can be calculated using only two points on a straight line. With the coordinates of two points, we can employ the slope of line formula.

Let the coordinates of those 2 points from where the line is passing is;

P1 = (x₁, y₁)

P2 = (x₂, y₂)

The slope of the  line is estimated as;

Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)

The values of the coordinates are given as;

(x₁, y₁) = (4,5) and,

(x₂, y₂) = (1,8)

Substitute the given values of coordinates in the formula to get the slope;

m = (8 - 5)/(1 - 4)

m = 3/(-3)

m = -1

Therefore, given the coordinates of such two points, the slope of a line passing through them is found to be -1.

For Example -

How many distinct triangles can you construct using angles of 30, 60, and 90 degrees?

Use a protractor to create one of the angles needed to form a triangle. You can adjust the side lengths to your desired length. Make another angle at the end of one of the sides, then link the sides together. You've constructed a triangle.

You should note that you chose the side lengths. This implies that you might choose differently. This allowed you to create an infinite number of distinct triangles using the same angles.

Hence, we can form infinite number of triangles when only the measurements of three angles is given

Step-by-step explanation:

triangle abc is Mathematically similar

Mary used 96 pounds of type b coffee this month.

Using algebraic expression and equation, we can solve how much of each type of coffee did Mary used that month.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

Given that that month, Mary made 181 pounds of the blend that is a mixture of two types of coffee, we can express this as:

181 = a + b

where a = pounds of type a coffee that costs $5.35 per pound

b = pounds of type b coffee that costs $4.15 per pound

Also, the total cost of the blend that month is $853.15, which is the sum of the total cost of the two types of coffee. We can express that as:

$853.15 = $5.35(a) + $4.15(b)

Using substitution method to solve the two equations,

181 = a + b   ⇒   a = 181 - b

$853.15 = $5.35(181 - b) + $4.15(b)

853.15 = 968.35 - 5.35b + 4.15b

5.35b - 4.15b = 968.35 - 853.15

1.2b = 115.2

b = 96

a = 181 - b

a = 181 - 96

a = 85

Hence, Mary used 85 pounds of type a coffee and 96 pounds of type b coffee that month.
