Answer: x-14

Step-by-step explanation:

We are being informed that the sum of the two numbers is 12 and their difference is 6.

Thus, the two numbers whose sum is equal to 12 and their difference is equal to 6 are 9 and 3 respectively.

Let those two unknown numbers be (a) and (b)

a + b = 12

Their difference;

i.e.

a - b = 6

So, we can equate the two equations together:

i.e.

a + b = 12     --- (1)

a - b = 6        --- (2)

From equation (1); Let a be:

a = 12 - b

Now, Let's replace the value of (a) into equation (2)

12 - b - b = 6

12 - 2b = 6

-2b = 6 - 12

-2b = -6

2b = 6

b = 6/2

b = 3

If b = 3;

Then from equation, we have:

a + b = 12

replace b with 3 from the above equation, we have:

a + 3 = 12

a = 12 - 3

a = 9

Therefore, we can conclude that the sum of the two numbers are 9 and 3. respectively

A valid inference is a conclusion that is true about the subject based on the evidence or premises provided.

Mathematically, we can represent a valid inference using logical notation. In the example above, we can use the following notation:

Premise 1: All humans are mortal.

Premise 2: Samantha is a human.

Conclusion: Samantha is mortal.

We can use the logical connective "if-then" to represent a valid inference. In this case, we can say, "If all humans are mortal, and Samantha is a human, then Samantha is mortal." This statement is true based on the premises provided.

To determine the validity of an inference mathematically, we can use rules of logic such as the law of detachment or the law of syllogism. The law of detachment states that if we have a conditional statement, "If p, then q," and we know that p is true, then we can validly infer that q is also true.

The law of syllogism is another rule of logic that helps us determine the validity of an inference. This rule states that if we have two conditional statements, "If p, then q," and "If q, then r," we can infer that "If p, then r" is true.

The actual distance between City C and City D is 4,224,000 feet.

What is total distance?

Whole distance refers to the actual travel distance between the origin and destination locations of the item.

We can use the given scale to convert the distance between City A and City B to feet:

500 miles = 500 * 5280 feet = 2,640,000 feet

Since 1.6 feet represents this distance on the wall map, we have:

1.6 feet = 2,640,000 feet / x

where x is the actual distance represented by 1.6 feet on the map. Solving for x, we get:

x = 2,640,000 feet / 1.6 feet = 1,650,000 feet per foot

Therefore, the  total distance between City C and City D, which is 2.56 feet on the map, corresponds to:

The positive solution for x in the equation log_x(1)/256 = -4/3 is x = 4.57

To solve the logarithm problem for the positive solution for x, we can use the following steps:

1. First, we can rewrite the equation in exponential form:
x^(-(4)/(3)) = 1/256

2. Next, we can raise both sides of the equation to the power of -(3)/(4) to isolate x:
(x^(-(4)/(3)))^(-(3)/(4)) = (1/256)^(-(3)/(4))

3. Simplify the left side of the equation:
x = (1/256)^(-(3)/(4))

4. Simplify the right side of the equation:
x = 256^((3)/(4))

5. Take the fourth root of both sides of the equation:
x = (256^((3)/(4)))^(1/4)

6. Simplify the right side of the equation:
x = 256^((3)/(16))

7. Simplify the exponent:
x = 256^(3/16)

8. Calculate the value of x:
x ≈ 4.57

H0:μ≤116 Ha:μ>116 The value of the test statistic z=1.12. Find the p-value is0.8869. The correct answer is option c. 0.8869.

To find the p-value, we need to use the standard normal table or a calculator with a normal distribution function. The p-value is the probability of observing a test statistic as extreme or more extreme than the one observed, given that the null hypothesis is true.

In this case, we are looking for the probability that z is greater than or equal to 1.12, given that the null hypothesis is true.

Using a standard normal table, we can find the area to the left of z=1.12, which is 0.8686. However, we are interested in the area to the right of z=1.12, which is 1 - 0.8686 = 0.1314.

This is the p-value for a one-tailed test. However, the hypothesis test in the question is a two-tailed test, so we need to double the p-value to get the final answer. The p-value for a two-tailed test is 2 * 0.1314 = 0.2628.

P35.00 + P15.00 × (t - 2) if 2 < t ≤ 12

P250.00 if t > 12

} is the required function to represent given information.

Expressions are commonly used in programming to perform calculations, manipulate data, and make decisions based on the results of evaluations.

To represent the parking fee using the function p(t), we need to consider the different rates depending on the number of hours parked. Here are the different cases we need to consider:

If t ≤ 2, the parking fee is P35.00

If 2 < t ≤ 12, the parking fee is P35.00 plus P15.00 for each hour (or fraction of it) after the first two hours. This can be represented by the equation:

p(t) = P35.00 + P15.00 × (t - 2)

If t > 12, the parking fee is a flat rate of P250.00.

We can combine these cases into a single function using a piecewise function. Here is the function p(t):

p(t) = {

P35.00 if t ≤ 2

P35.00 + P15.00 × (t - 2) if 2 < t ≤ 12

P250.00 if t > 12

}

This function represents the parking fee in terms of the number of hours parked (t). To use it, simply substitute the number of hours parked into the function and calculate the resulting fee. For example, if you parked for 4 hours, the fee would be:

p(4) = P35.00 + P15.00 × (4 - 2) = P65.00

Therefore, p(t) = {

P35.00 if t ≤ 2

P35.00 + P15.00 × (t - 2) if 2 < t ≤ 12

P250.00 if t > 12

The decimal multiplier to increase by 6.1% is 1.061.

What is multiplication ?

Multiplication is a mathematical operation used for finding the result of adding a number to itself a certain number of times. It involves multiplying two or more numbers to find their product. For example, 2 times 3 is equal to 6, written as 2 x 3 = 6. In multiplication, the numbers being multiplied are called factors, and the result is called the product. Multiplication is often denoted by the symbol "x" or a dot ".".

A decimal multiplier is a factor that is used to increase or decrease a number by a certain percentage. It is commonly used in financial calculations such as interest rates, discounts, and taxes.

To find the decimal multiplier to increase by a certain percentage, you can use the following formula:

Decimal multiplier = 1 + (percentage increase/100)

For example, if you want to increase a number by 6.1%, the decimal multiplier would be:

Decimal multiplier = 1 + (6.1/100)

Decimal multiplier = 1.061

This means that to increase a number by 6.1%, you would multiply it by 1.061. For example, if you had a number of 100, to increase it by 6.1%, you would multiply it by 1.061 to get 106.1.

On the other hand, if you wanted to decrease a number by a certain percentage, you would use a decimal multiplier that is less than 1. For example, to decrease a number by 10%, the decimal multiplier would be 0.9, which means you would multiply the number by 0.9 to get the new decreased value.

Therefore, decimal multiplier to increase by 6.1% is 1.061.

The total miles that all eight vehicles drove is 375 miles, and the correct answer is A. 375.

To calculate the total miles that all eight vehicles drove, we need to add up the miles driven by the seven vehicles that completed the trip and the miles driven by the eighth vehicle that only completed 50% of the journey.

The seven vehicles that completed the trip each drove 50 miles, so their total mileage is 7 x 50 = 350 miles.

The eighth vehicle only completed 50% of the journey, so it drove 50 x 0.50 = 25 miles.

To find the total miles driven by all eight vehicles, we add the miles driven by the seven vehicles and the miles driven by the eighth vehicle:
350 + 25 = 375 miles

So if you were to work each of these out x + 6 = 8 that problem gives us positive 2, when we are looking for a -2 so that answer is ruled out. Then you go to x-6=8 you move the -6 and add it to the 8 and you get x = 14 still not our answer so thats also ruled out. Then x-8=6 is the same thing as the last one but with a -8 instead of a 6 but you get the same answer which is x=14 so not that one either. Then you work on the choice x+8=6 and you subtract 8 from both sides and you end up with a -2. So our final answer is C: X+8=6
