Find and interpret the mean absolute deviation of the data. Round your answer to the nearest tenth, if necessary. The mean absolute deviation is . Question 2 response - correct
Required data:
_______________
| 60 | 105 | 80 | 125 |
| 140 | 95 | 65 | 170 |
----------------------------
Answer:
Mean absolute deviation = 30
Variability of the data about the mean value is 30
Step-by-step explanation:
Mean = Σx / n
n = sample size = 8
Mean = (60 + 105 + 80 + 125 + 140 + 95 + 65 + 170) = 840 / 8 = 105
Mean absolute deviation = Σ|x - mean| ÷ n
( |60-105| + |105-105| + |80-105| + |125 - 105| + |140-105| + |95-105| + |65-105| + |170-105|) / 8
(45 + 0 + 25 + 20 + 35 + 10 + 40 + 65) / 8
240 / 8
= 30
The variability of data about the central point or mean value is 30.

In order to know if a triangle is a right triangle on a coordinate plane, you can find the lengths of all three sides of the triangle using the distance formula and apply the Pythagorean theorem.
How to know if it's a triangleFind the lengths of the three sides of the triangle using the distance formula.
Once you have the lengths of the sides, check if any of the three sides satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In other words, if a² + b² = c², where c is the longest side, then the triangle is a right triangle.
If one of the sides satisfies the Pythagorean theorem, then the triangle is a right triangle.

What are the properties of similar geometric figures?In Mathematics and Geometry, two geometric figures are said to be similar when the ratio of their corresponding side lengths are equal and their corresponding angles are congruent.
Hence, the lengths of the pairs of corresponding sides or corresponding side lengths are proportional to one another when two (2) geometric figures are similar.
Since line segment AB is parallel to line segment CD and parallel to line segment EF, we can logically deduce that they are congruent because they can undergo rigid motions. Therefore, we have the following proportional side lengths;
\(\frac{AC}{CE} =\frac{BD}{DF}\)
\(\frac{CE}{DF} =\frac{AE}{BF}\)

(hint: a tree diagram might help. round your answer to three decimal places.)
The probability that the taxi at fault was blue 0.328125 or 32.8125%.
Probability of blue cab is
P(B) = 0.14;
Probability of green cab is
P(G) = 0.86;
Probability of correctly distinguish is
P(C)=0.75
The probability that the witness identified a blue car is determined by the probability of the cab being blue and being correctly distinguished by the witness, added to the probability of the cab being green and being incorrectly distinguished by the witness.
P(W b) = P(B)*P(C)+P(G)*(1-P(C))
= 0.14*0.75 +0.86*0.25
=.32
The probability that a blue car is at fault is given by the probability of a blue car being correctly identified divided by the probability of a blue car being identified by the witness:
P = P(B)*P(C)/P(W b)
P = 0.14*0.75/0.32
P = 0.328125
The probability is 0.328125 or 32.8125%.

The pH of the cleaning compound is 2.51.
What is pH?pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions.
Given that, The hydrogen ion concentration, [H+], in a certain cleaning compound is [H+]=3.3x10^-12.
[OH-] = 1.0*10^-14/3.3*10^-12 = 0.303*10^-12

Let I and J be ideals and P a prime ideal of R. Prove that if I J ⊆ P then I ⊆ P or J ⊆ P.
We have shown that if IJ ⊆ P, then either I ⊆ P or J ⊆ P. Hence, the statement is proven, for I and J be ideals and P a prime ideal of R. Since P is prime, so we have the following inequality:(I intersection P) (J intersection P) ⊆ P²
Now, since P is prime so P² is a prime ideal too, thus one of the ideals I intersection P and J intersection P must be contained in P.
If I intersection P ⊆ P, then I ⊆ P. If J intersection P ⊆ P, then J ⊆ P. Therefore, I ⊆ P or J ⊆ P.
To prove the statement, let's assume that I and J are ideals of a ring R, and P is a prime ideal of R. We want to show that if IJ ⊆ P, then either I ⊆ P or J ⊆ P.
Suppose that IJ ⊆ P, We will proceed by contradiction.
Assume that I is not contained in P, which means there exists an element a ∈ I such that a ∉ P.
Since P is a prime ideal, it is closed under multiplication, so aJ ⊆ PJ ⊆ P.
Now consider the product (aJ)(a⁻¹). Since a ∉ P, a⁻¹ ∈ R\P (the complement of P in R).
Therefore, (aJ)(a⁻¹) ⊆ P(a⁻¹), and we have:
aJ ⊆ P(a⁻¹)
Multiplying both sides by a, we get:
a(aJ) ⊆ a(P(a⁻¹))
a²J ⊆ Pa⁻¹
Since J is an ideal, a²J ⊆ aJ ⊆ P(a⁻¹), and by induction,
we have aⁿJ ⊆ Pa⁻ⁿ for any positive integer n.
Consider the element aⁿ ∈ aⁿJ.
Since aⁿJ ⊆ Pa⁻ⁿ, aⁿ ∈ Pa⁻ⁿ.
This implies that aⁿ is an element of the prime ideal P for any positive integer n.
Since R is a ring, there exists a positive integer m such that aᵐ = aᵐ⁺¹ for some m⁺¹ > m.
This means that aᵐ (a - 1) = 0.
Since aᵐ ∈ P and P is a prime ideal, either a or (a - 1) must be in P.
If a is in P, then I ⊆ P, which is one of the conditions we want to prove.
If (a - 1) is in P, then consider the element 1 ∈ R. Since (a - 1) is in P, we have 1 - (a - 1) = a ∈ P.
This implies J ⊆ P, which is the other condition we want to prove.
In either case, we have shown that if IJ ⊆ P, then either I ⊆ P or J ⊆ P. Hence, the statement is proven.

Answer: \((w^{\frac{1}{5} } )^{3}\)
Step-by-step explanation:
The root of a number, say \(\sqrt[n]{x}\) is equal to \(x^{\frac{1}{n} }\). So, \(\sqrt[5]{w^{3} } = (w^{3} )^{\frac{1}{5} }\). Since when dealing with an exponent of a number raised to an exponent you multiply the exponents, due to the associative property it does not matter which order you do the exponents in. So, \((w^{3} )^{\frac{1}{5} }= (w^{\frac{1}{5} } )^{3}\), which is answer D.

A simple interest is calculated for payments on the initial capital.
If the total interest was $174.12.
If the interest is on a year. You calculated the interes of one year. The 10% of $278:
\(278\cdot\frac{10}{100}=27.8\)In a year the interest is $27.8.
Then, $174.12 divided into $27.8 is the number of years of the loan:
\(\frac{174.12}{27.8}=6.26\approx6\)Then, the loan was for 6 years
