The square root of 8 is an irrational number, because it is not an exact square root.
What are rational and irrational numbers?The rational numbers are composed by the set of all numbers that can be represented by fractions, such as whole numbers, terminating decimals, or repeating decimals.
The irrational numbers, conversely, are composed by the set of numbers that cannot be represented by fractions, such as non-exact roots and non-terminating decimals.
The square root of 8 is non-exact, hence it is an irrational number, as the square root is then a non-terminating and non-repeating decimal.

22. In the diagram of trapezoid ABCD below, AB || DC, AD = BC, mA = 4x+20, and m/C= 3x - 15. What is m
1) 25
2) 35
3) 60
4) 90
Hello,
I hope you and your family are doing well!
Since AB || DC and AD = BC, trapezoid ABCD is a parallelogram, which means that its opposite sides are parallel and congruent. Therefore, angle A is congruent to angle C and angle B is congruent to angle D.
Since mA = 4x+20 and m/C= 3x - 15, we know that mA + mC = 4x+20 + 3x - 15 = 7x + 5.
Since angles A and C are congruent, we can set their measures equal to each other:
mA = mC
4x+20 = 3x - 15
Solving this equation for x gives us x = 5. Substituting this value back into the equation mA + mC = 7x + 5 gives us:
mA + mC = 7 * 5 + 5 = 35
The answer is 35 (Option 2)
Please give this answer 5 stars and brainliest if you find it helpful.

it has been estimated that about 30% of frozen chickens are contaminated with enough salmonella bacteria to cause illness if improperly cooked. chickens are delivered to grocery stores in crates of 24. assume the chickens are chosen for inclusion in a crate at random. what is the probability that a randomly selected crate has more than 4 contaminated chickens?
Using the binomial distribution, it is found that there is a 0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.
For each chicken, there are only two possible outcomes, either they are contaminated, or they are not. The chickens are independently selected, hence, the binomial distribution is used.
What is the binomial probability distribution formula?
The formula is:
P(X=x) = Cₙ,ₓ.pˣ.(1-p)ⁿ⁻ˣ
Cₙ,ₓ = n!/x!(n-x)!
The parameters are:
x is the number of successes.
n is the number of trials.
p is the probability of a success on a single trial.
In this problem:
About 30% of frozen chickens are contaminated, hence p=0.3.
Chickens are delivered to grocery stores in crates of 24, hence n=24
The probability that a certain crate has more than 4 contaminated chickens is:
P(X>4)=1-P(X≤4)
In which:
P(X≤4) = (P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)
Then
P(X=x) = Cₙ,ₓ.pˣ.(1-p)ⁿ⁻ˣ
P(X=0) = C₂₄,₀.(0.3)⁰.(0.7)²⁴ = 0.0002
P(X=1) = C₂₄,₁.(0.3)¹.(0.7)²³ = 0.0020
P(X=2) = C₂₄,₂.(0.3)².(0.7)²² = 0.0097
P(X=3) = C₂₄,₃.(0.3)³.(0.7)²¹ = 0.0305
P(X=4) = C₂₄,₄.(0.3)⁴.(0.7)²° = 0.0687
Hence
P(X≤4) = (P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)
= 0.0002+0.0020+0.0097+0.0305+0.0687
= 0.1111
0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.

This situation would be known as a positive-sum game for team members.
In game theory, a scenario is said to as a positive-sum game if the sum of the profits and losses is more than zero. When resources are somehow expanded and a strategy is developed that satisfies the wants and requirements of everyone involved, a positive sum results. One instance would be when two parties engage in a competition and, regardless of the outcome, both sides stand to profit financially. In situations of distributive bargaining, where various interests are discussed in order to satisfy everyone's wants, positive-sum outcomes take place.

The relationship between the values of two different currencies is modeled by a linear function that varies depending on the current value of each currency. The table shows the relationship between an amount in U.S. dollars, x, and the equivalent amount in euros, f(x), where f(x) = x/1.06.
The inverse function is given by f⁻¹(x) = 1.06x. 2 euros is equivalent to 2.12 U.S. dollars. 4 euros is equivalent to 4.24 U.S. dollars
How to find the inverse function?Given that: the two different currencies is modeled by a linear function f(x) = x/1.06
where, x = an amount in U.S. dollars and f(x) = the equivalent amount in euros
To find the inverse function f⁻¹(x). Let y = f(x):
y = x/1.06
x = 1.06y
Since x = f⁻¹(y) = 1.06y
Thus, f⁻¹(x) = 1.06x
Note: f⁻¹(x) will help you convert from euros to dollar
2 euros to dollars will be:
f⁻¹(x) = 1.06x
f⁻¹(2) = 1.06(2) = 2.12
Thus, 2 euros is equivalent to 2.12 U.S. dollars
4 euros to dollars will be:
f⁻¹(x) = 1.06x
f⁻¹(4) = 1.06(4) = 4.24

Using percentages, we can determine that the Luce family pays $16.34 in state tax because there are no federal withholding exemptions.
What is the Percentage?A percentage is a relative figure that has the ability to represent 1/100th of any quantity.
Since 1% denotes one percent, 100 percent and 200 percent indicate the full amount and double the quantity, respectively.
By multiplying by 100 and inserting the "percentage sign"%, a ratio and fraction can be transformed into a percentage.
So, Luce is single and makes $763 twice weekly.
She does not request any compensation from federal withholding.
The value of this amount ranges from $760 to $780.
If we look at the table in the issue, the federal tax for this slab is $86.
Federal taxes now make up 19% of all state taxes.
Hence, the $86 in federal tax at a rate of 19% is:
Tax = 86 * 19/100
Tax = 16.34
Therefore, using percentages, we can determine that the Luce family pays $16.34 in state tax because there are no federal withholding exemptions.

the manager at a local movie theater has collected data for a long period of time and has concluded that the revenue from concession sales during the first show each evening is normally distributed with a mean equal to $336.25 and a variance equal to 1,456. based on this information, what are the chances that the revenue on the first show will exceed $800?
The chances that the revenue on the first show will exceed $800 when mean revenue is $336.25 and standard deviation is $38.16 is essentially zero. i.e. 0
A normal distribution is a type of continuous probability distribution in which the majority of data points cluster in the middle of the range, while the remainder taper off symmetrically toward either extreme. The mean of the distribution is also known as the middle of the range.
The normal distribution is primarily used to calculate the likelihood of an observation in a distribution falling above or below a given value.
Given,
Mean, [tex]\mu[/tex] = 336.25
variance, [tex]\sigma^2[/tex]= 1456
then,
standard deviation, [tex]\sigma = \sqrt{1456}[/tex] = 38.16
To determine the chances that the revenue on the first show will exceed 800 is1:
[tex]1-p(z=\frac{x-\mu}{\sigma})\\\\=1-p(z=\frac{800-336.25}{38.16})\\\\=1-p(z=\frac{436.75}{38.16})\\\\=1-p(z=12.15)\\\\=1-1=0[/tex]

A box of a dozen donuts, the probability that you randomly choose a chocolate donut from the box is 1/3 ....
What is Probability?Probability is the study of occurrence of chance of a particular result. It is calculated by ratio of favourable outcomes and the total possible outcomes.
We have box of a dozen donuts contains,
The number of glazed donuts in box = 5
The number of blueberry donuts in box = 3
The number of chocolate donuts in box = 4
So, the total number of donuts = 12
We have to calculate probability that you randomly choose a chocolate donut from the box, say P(X) .
That is one donut is selected randomly from box.
P(X) = Number of favourable cases/ Total number of possible outcomes
= 4/12 = 1/3
Thus, the required probability is 1/3.

Answer:
∠1 = 33°∠2 = 47°Step-by-step explanation:
You want to know the measure of angle 1 given that angle 2 is 14° more and their total is 80°.
Angle sum theoremThe angle sum theorem tells you the whole is equal to the sum of the parts.
∠1 +∠2 = ∠ABD
Using the given values, we have ...
∠1 +(∠1 +14°) = 80°
2×∠1 = 66° . . . . . . . . . subtract 14°
∠1 = 33° . . . . . . . . divide by 2
∠2 = 33° +14°
∠2 = 47°

What is probability?Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.
Here,

The height, h, in feet of a piece of cloth tied to a waterwheel in relation to sea level as a function of time, t, in seconds can be modeled by the equation h = 15 cosine (startfraction pi over 20 endfraction t). How long does it take for the waterwheel to complete one turn?.
The waterwheel takes 40 seconds to make one turn.
To find the period of the function, we need to find the time it takes for the function to repeat itself. In this case, we want to find the time it takes for the waterwheel to complete one turn.
The function h = 15 cos (π/20) t models the height of the cloth in relation to sea level as a function of time.
The cosine function has a period of 2π, so the period of the function h = 15 cos (π/20) t will be 2π divided by (π/20) which simplifies to 40 seconds.
Therefore, it takes 40 seconds for the waterwheel to complete one turn.
