Answer:
110 miles
Step-by-step explanation:
If EACH GALLON of gas gives 22 miles, 5 GALLONS will give 5 times that. So,
[tex]22*5=110[/tex]
So in 5 gallons, Khan's should get around 110 miles
Twice a number is 36 less than -104. Find the number
The question 'twice a number is 36 less than -104' is an algebraic problem which can be solved by simplifying the equation '2x = -104 - 36' and dividing through by two. The solution to the equation is x = -70.
Explanation:The problem presented is a simple algebraic equation. The question is: Twice a number is 36 less than -104. This can be expressed with the equation 2x = -104 - 36.
To solve for x, we first simplify the right side of the equation: 2x = -140. Next, we isolate x by dividing both sides of the equation by 2: x = -140 / 2. So, the number x is -70.

What step in the construction of copying a line segment ensures that the new line segment has the same length as the original line segment?
To copy a line segment and ensure it has the same length as the original, use a compass to measure and create a duplicate line segment.
Explanation:To copy a line segment and ensure that the new line segment has the same length as the original, we can use a compass. Here are the steps:
Place the compass needle on one endpoint of the original line segment.Open the compass to the length of the original line segment.Without changing the compass width, place the compass needle on the other endpoint of the original line segment and draw an arc.Use the compass to measure the same length on the arc and draw a line segment connecting the two marks.By using this method, we can create a duplicate line segment with the same length as the original.

What is the inverse of the function f(x) = 2x – 10? h(x) = 2x – 5 h(x) = 2x + 5 h(x) = x – 5 h(x) = x + 5
The inverse of a function is gotten by swapping the x and y coordinates.
The inverse of function f(x) is[tex]h(x) = \frac x2 + 5[/tex]
Given
[tex]f(x) = 2x - 10[/tex]
Rewrite as:
[tex]y = 2x - 10[/tex]
Swap x and y
[tex]x = 2y - 10[/tex]
Solve for y
[tex]2y = x + 10[/tex]
Divide by 2
[tex]y = \frac x2 + 5[/tex]
So, we have:
[tex]h(x) = \frac x2 + 5[/tex]
Hence, the inverse function is[tex]h(x) = \frac x2 + 5[/tex]

Determine whether the dilation from A (blue figure) to B (green figure) is an enlargement or reduction, then find the scale factor of the dilation.
a. reduction; scale factor of 2/5
b. enlargement; scale factor of 5/2
c. reduction; scale factor of 2/3
d. enlargement; scale factor of 3/2
Answer:
Option B
Step-by-step explanation:
In the figure attached we have to find the scale factor of dilation of figure A to figure B.
Since figure A is smaller than figure B, it concludes figure A has been enlarged to form figure B.
Now we have to find the scale factor of enlargement.
Scale factor = [tex]\frac{\text{one side of the larger figure}}{\text{one side of the smaller figure}}[/tex]
= [tex]\frac{5}{2}[/tex]
Therefore option B is the correct answer.
The U in the upper right corner stands for the
bigger set
universal set
infinite set
complement
Answer:
Universal set
Step-by-step explanation:
We need to find U in the upper right corner stands for what
Option 1 : bigger set
We cannot say this a bigger set without comparing it with another sets and since it is also containing another sets So, it is not said to be a bigger set.
Option 1 is wrong .
Option 2 : Universal Set
Definition of Universal Set : The set which contains all elements or all objects and of which all other sets are subsets.
Since we can see that SET M and SET N are contained in SET U
Thus U is a universal set.
Option 2 is correct .
Option 3: infinite set
we can see in the figure that it is finite set .
So, it is not infinite set.
Option 3 is wrong .
Option 4: complement
it is not a complement set (refer given figure )
Option 4 is wrong .

What is the greatest common factor of 34n and 8n^2?
The greatest common factor of 34n and 8n² is 2n, as both expressions share the variable n and the highest common numerical coefficient is 2.
The greatest common factor (GCF) of two algebraic expressions can be found by identifying the highest powers of common factors in the terms. For the expressions 34n and 8n², both terms have n as a common factor. Since we want the greatest common factor, we take the highest power of n that appears in both terms, which is n (not n² because n is the highest power in the least degree term, 34n). Next, we find the GCF of the numerical coefficients 34 and 8, which is 2. Therefore, the greatest common factor of 34n and 8n² is 2n.

Which of these statements about statistical models is true? I. Statistical models help better understand real-world systems. II. Statistical models represent the real world. III. Statistical models help predict future behavior.
Final answer:
Statistical models help understand real-world systems, represent simplified versions of reality, and aid in predicting future behavior. However, they are not perfect and contain uncertainties.
Explanation:
The question at hand is about statistical models and their characteristics. Statistical models do indeed serve several key functions, and among the statements listed, all are true to a certain extent:
Statistical models help better understand real-world systems by simplifying complex phenomena and making them more approachable for analysis.Statistical models represent the real world, but it is important to note that they are simplifications and may not capture all the nuances of real-world behavior.Statistical models help predict future behavior by using historical data and probabilistic methods to make informed guesses about what might happen under similar circumstances.However, it is crucial to remember that while statistical models are powerful tools for interpretation and prediction, they are not perfect representations of reality and come with inherent uncertainties and limitations.
