To round 2.767.545 to the nearest ten, we look at the digit in the tens place (4) and the following digit (5). Since the following digit is 5, we round up, resulting in 2.767.550.

When rounding 2.767.545 to the nearest ten, we must focus on the digit in the tens place and the digit that comes immediately after it. In this case, the digit in the tens place is 4, and the one following it is 5. According to the standard rules for rounding numbers, if the first dropped digit is 5 or higher, we round up. Thus, rounding 2.767.545 to the nearest ten, we get 2.767.550.

Answer: The values of the function V(x) over the domain (2, 5, 7) are 17881.66, 12,606.01 and 9985.224.

Explanation:

The cost of car is $22575 and the value of car depreciate at a rate of 11% per year.

The value of car can be modeled by the equation,

[tex]V(x)=22,575(0.89)^x[/tex]

Where is number of years after purchase of car or the age of car. We have to find the value of the function over the domain (2,5,7), so put x=2,

[tex]V(x)=22,575(0.89)^2=17881.66[/tex]

It means the value of car will be $17881.66 after two years.

put x=5,

[tex]V(x)=22,575(0.89)^5=12,606.01[/tex]

It means the value of car will be $12,606.01 after five years.

put x=7,

[tex]V(x)=22,575(0.89)^7=9985.224[/tex]

It means the value of car will be $9985.224 after seven years.

To convert a mixed number to its lowest form, one needs to change the mixed number into an improper fraction and then reduce this improper fraction to the lowest possible fraction. To do these conversions, one needs to perform a few calculations. One also has to understand the definitions of "mixed number," "improper fraction" and "proper fraction."

A proper fraction is a fraction that has a lower number in the numerator and a higher number in denominator, such as the fraction three-fourths. An improper fraction is the inverse of this, which entails the higher number in numerator and lower number in the denominator, like 5/3. A mixed number is a whole number with a fraction, such as 1 3/4.

To convert the mixed number 1 3/4, one has to multiply the denominator 4 by the whole number 1 that gives 4, add this 4 to the 3 in the numerator to get 7 and place 7 over the denominator to find the improper fraction 7/4. In this case, this is the lowest form for this mixed number. However, if the mixed number is 6 4/6, then this converts to the improper fraction 40/6. One can divide the numerator and denominator of 40/6 by 2 to find that 20/3 is the lowest form for the mixed number 6 4/6.To convert a mixed number to its lowest form, one needs to change the mixed number into an improper fraction and then reduce this improper fraction to the lowest possible fraction. To do these conversions, one needs to perform a few calculations. One also has to understand the definitions of "mixed number," "improper fraction" and "proper fraction."

The first equation is open, since it has an unsolvable variable. 1x could be anything!

The second equation is false, because 20 - 11 = 9    not 11.

The last equation is true,  7 + 10 does equal 17!

1x + 4 = 10

x = 10 - 4

x = 6 (true)

--------------------

20 - 11 = 11

20 - 11 = 9 (false)

-----------------------

7 + 10 = 17 (true)

Yes it is.

an example that opposes or contradicts an idea or theory.

Final answer:

A counterexample is an example that disproves a statement or argument by showing that the conclusion can be false even when the premises are true. This concept is widely used in philosophy to test and refine arguments and definitions.

Explanation:

A counterexample is a specific case or example that refutes a general assertion or proposition. In philosophical reasoning and critical thinking, counterexamples hold particular significance as they can demonstrate the invalidity of an argument. The argument may have premises that are all true, but the conclusion drawn from these premises is shown to be false through the counterexample. Philosophers often use this method to refine definitions, understand the essence of concepts, and advance epistemological theories about knowledge and justification. Furthermore, it is a useful practice to generate counterexamples in order to test the validity of our own beliefs and arguments.

To identify counterexamples, one must consider a statement or argument and then conceive of a scenario where despite the premises being true, the conclusion does not follow. This act of finding counterexamples is critical for ensuring the soundness of deductive reasoning and often leads to the revision or abandonment of flawed concepts or arguments.

Answer:

x < -19/13

Step-by-step explanation:

The solution to the inequalities −9x+2>18 and 13x+15≤−4 is to find values of x that satisfy either x < ∘⅗⁄3 or x ≤ ∘⅗/13.

To solve the equations −9x+2>18 OR 13x+15≤−4, we need to treat them separately as two different inequalities.

For the first inequality, subtract 2 from both sides to get −9x > 16, then divide by −9 to isolate x, which gives us x < ∘⅓⁄9 or x < ∘⅗⁄3.

For the second inequality, subtract 15 from both sides to get 13x ≤ −4 − 15 or 13x ≤ −19. Finally, divide by 13 to isolate x, leading to x ≤ −⅓⁄13 or x ≤ ∘⅗/13.

Therefore, the solution to the system of inequalities is any x that satisfies at least one of these conditions: x < ∘⅗⁄3 or x ≤ ∘⅗/13.

Answer:

The answer is A.

Step-by-step explanation:

For this question, just multiply the number (300) by the percent (.95)

Your answer is 285 women

To determine the number of women with babies in good or excellent health, we multiply the total number of women (300) by the percentage of women with healthy babies (95%). We find that 285 out of the 300 women had babies in good or excellent health.

In the study mentioned, it is stated that 95% of pregnant women with good to excellent health diets had babies in good or excellent health. The total number of women considered in this study is 300. To calculate the exact number of women who had babies in good or excellent health, we can apply the concept of percentage which means 'per 100'. So, 95% of 300 women equals (95/100)*300 = 285 women. Therefore, out of 300 women, 285 women had babies in good or excellent health.
