Therefore, 2 with an exponent of 0 is equal to 1.
When a number is raised to an exponent of 0, the result is 1. This applies to any non-zero number, including 2. Therefore, 2 with an exponent of 0 is equal to 1.
The reason is that any number raised to the power of 0 is 1. This is because any number multiplied by 1 is itself, and any number raised to the power of 1 is itself. Therefore, raising a number to the power of 0 is the same as multiplying it by 1, so the result is 1.
It is also important to note that a number raised to the power of 1 is the number itself, so 2^1=2, 2^2=4, 2^3=8 and so on.
Therefore, 2 with an exponent of 0 is equal to 1.

What is 8 11/12 + 9 5/18
Step-by-step explanation:
The picture is the full explanation for this question answer.
18.19 is the solution for the given improper function.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
To add 8 11/12 and 9 5/18, we need to first find a common denominator. The smallest number that both 12 and 18 divide evenly is 36.
Converting 8 11/12 to an improper fraction:
8 11/12 = (8 × 12 + 11) / 12 = 107/12
Converting 9 5/18 to an improper fraction:
9 5/18 = (9 × 18 + 5) / 18 = 167/18
Now that we have a common denominator of 36, we can add the two fractions:
107/12 + 167/18 = (107 × 3) / (12 × 3) + (167 × 2) / (18 × 2)
= 321/36 + 334/36 = 655/36
So 8 11/12 + 9 5/18 = 655/36 or approximately 18.19.

A machine has 28 identical components which function independently. The probability that a component will fail is 0.19 . The machine will stop working if more than three components fail. Find the probability that the machine will be working. Round to the nearest thousandth.
By definition of a binomial random variable, the probability that the machine will be working is 0.82045.
Definition of probabilityFirst of all, you should know that the Probability is the greater or lesser possibility that a certain event will occur.
In other words, the probability establishes a relationship between the number of favorable events and the total number of possible events.
Definition of random variableOn the other hand, a random variable is a function that associates a real number, perfectly defined, to each sample point.
A random variable is discrete if the numbers it gives rise to are integers.
Definition of binomial distributionFinally, a binomial distribution is a discrete probability distribution that describes the number of successes in performing n independent experiments on a random variable.
The expression to calculate the binomial distribution is:
P(X=x)=([tex]n\\ x[/tex]) pˣ qⁿ⁻ˣ
Where:
n = Number of trials/experimentsx = Number of successesp = Probability of successq = Probability of failure (1-p)Remember that:
([tex]n\\ x[/tex])=[tex]\frac{n!}{x!(n-x)!}[/tex]
where the exclamation mark represents the factorial symbol, that is, the product of all positive integers from 1 to n.
Probability that the machine will be workingA machine has 28 identical components which function independently. The probability that a component will fail is 0.19.
The following random variable is defined:
x= the number of components will stop working.
Being n the total number of pieces (in this case, 12 pieces) and p the probability of success (the piece fails, in this case 0.19), the expression to be used is expressed as:
P(X=x)=([tex]12\\ x[/tex]) 0.19ˣ (1-0.19)¹²⁻ˣ
P(X=x)=[tex]\frac{12!}{x!(12-x)!}[/tex] 0.19ˣ (0.81)¹²⁻ˣ
Since the machine will stop working if more than three components fail, you need to know the probability that the machine will be working if 3 or less than 3 components fail. In other words, it may be that 0, 1, 2 or 3 pieces are broken and the machine continues to work:
P(X≤3)= P(X=0) + P(X=1) + P(X=2) + P(X=3)
Then:
P(X≤3)= [tex]\frac{12!}{0!(12-0)!}[/tex] 0.19⁰ (0.81)¹²⁻⁰ + [tex]\frac{12!}{1!(12-1)!}[/tex] 0.19¹ (0.81)¹²⁻¹ + [tex]\frac{12!}{2!(12-2)!}[/tex] 0.19² (0.81)¹²⁻² + [tex]\frac{12!}{3!(12-3)!}[/tex] 0.19³ (0.81)¹²⁻³
Solving:
P(X≤3)= [tex]\frac{12!}{0!12!}[/tex] ×1×(0.81)¹² + [tex]\frac{12!}{1!11!}[/tex] 0.19×(0.81)¹¹ + [tex]\frac{12!}{2!10!}[/tex] 0.19²×(0.81)¹⁰ + [tex]\frac{12!}{3!9!}[/tex] 0.19³×(0.81)⁹

P(X≤3)= (0.81)¹² + 2.28×(0.81)¹¹ + 2.3826×(0.81)¹⁰ + 1.50898×(0.81)⁹

Answer:
Step-by-step explanation:
The visualization of "4.298" on the number line is attached below.
How does the dot plot work?Suppose we're measuring something whose values are numeric.
For each value of that thing we observe, we plot a dot above that value in the number line.
Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.
Thus, suppose if we observed the value 'x', then we will make a dot above 'x'. If there is already a dot over 'x', then we will make a new dot over that dot.

.slope of the line
.equation of the line
.y-intercept
.slope of a line perpendicular to the given line
Answer:
slope: undefined
equation: x = p
y-intercept: there is none
slope of perpendicular: 0
Step-by-step explanation:
points: (p, a), (p, -a)
slope = (-a - a)/(p - p) = -2a/0
The slope is undefined since the line is vertical.
equation: x = p
Since p ≠ 0, the vertical crosses the x-axis at a point that is not x = 0 and never intersects the y-axis, so the is no y-intercept.
A line perpendicular to he given line is a horizontal line.

What type of triange is this?
Answer: Right isosceles triangle
Step-by-step explanation: This is fairly easy to determine.
Side BC is roughly congruent to side CD. Both sides start from 0 to 7 and a little bit.
Side AC is also congruent by the reflexive property and is also congruent to both triangles' sides because it lines up perfectly. Since both sides BC and CD are congruent, the segment AC likely is perpendicular to segment BD and cuts it into 2 equal and congruent sides.
Sides AB and AD cannot be determined to be congruent.
Since the right angles are between two congruent sides of two triangles, the two triangles are congruent by the Side Angle Side congruence theorem.
Thus, we can say these are 2 right isosceles triangles conjoined together. Hope this helped!

What is WX? Explain your reasoning.
I know all the angles but I’m not sure on how to find WX or what equation to use.
Answer:
180
Step-by-step explanation:
Solution 1: Any straight line is 180 degrees.
Solution 2: Angle WX=Angle YZW+ Angle YZX
Angle YZW=Angle YZX=90
Angle YZW+ Angle YZX=90+90=180
So Angle WX=180
Answer:
Step-by-step explanation:
You can find WX if you know some special properties of special triangles:
1. A 45-45-90 triangle (a triangle with angle measures of 45°, 45°, and 90°) will have a 1:1:√2 ratio (the legs of the triangle are the same length and the hypotenuse is the length of any leg times √2)
2. A 30-60-90 triangle (a triangle with angle measures of 30°, 60°, and 90°) will have a 1:√3:2 ratio (the hypotenuse is twice the measure of the shorter leg, and the longer leg is √3 times the length of the shorter leg)
For reference, a leg is a side on a right triangle that isn't the hypotenuse.
In this picture, the first type of triangle is on the right, and the second type is on the left.
WZThe shorter leg on the left triangle has a length of 10, and WZ is the longer leg. The longer leg is √3 times the shorter one, so WZ = 10√3
ZXBoth legs of a 45-45-90 triangle have the same measure, so ZX is 10.
Since WX is made up of WZ and ZX, it's length is the sum of both lengths.
