x = # of hours

80x + 90x = 408

Combine like terms.

170x = 408

Divide both sides by 408

x = 2.4 hours

It will take the trains 2.4 hours to be 408 miles apart.

The two trains will travel their 408-mile distance in around 2.4 hours.

To determine the time it will take for the two trains to be 408 miles apart, we can use the concept of relative motion.

Since the two trains are moving away from each other in opposite directions,

their speeds are added to calculate the rate at which the distance between them is increasing.

Let's consider the time it takes for the trains to be 408 miles apart:

Distance = Rate × Time

For the eastbound train:

Distance = 90 miles/hour × Time

For the westbound train:

Distance = 80 miles/hour × Time

Since the trains are moving away from each other, their distances traveled add up to the total distance between them:

90 miles/hour × Time + 80 miles/hour × Time = 408 miles

Combining like terms:

170 miles/hour × Time = 408 miles

To solve for Time, isolate it by dividing both sides of the equation by 170 miles/hour:

Time = 408 miles / 170 miles/hour

Now we can calculate the time:

Time = 2.4 hours

Therefore, it will take approximately 2.4 hours for the two trains to be 408 miles apart.

Let x represent the charge for a book

Let y represent the monthly fee​

one month she received 3 books and was charged 74.85. This would be expressed as

3x + y = 74.85

the next month she received 5 books and was charged 116.75. This would be expressed as

5x + y = 116.75

We would solve both equations simultaneously by subtracting the second equation from the first equation. it becomes

3x - 5x + y - y = 74.85 - 116.75

- 2x = - 41.9

x = - 41.9/-2

x = 20.95

We would find y by substituting x = 20.95 into the first equation. It becomes

3(20.95) + y = 74.85

62.85 + y = 74.85

y = 74.85 - 62.85

y = 12

The charge for a book is 20.95

The monthly fee is 12

The set of odd integers between three and five can be found to be D. A null set.

An odd number is defined as an integer that cannot be split exactly by two. For example: 1, 3, 5, 7, and so on.

We are asked about the set of odd integers ranging from 3 to 5. Because the question asks for odd numbers between 3 and 5, 3 and 5 will not be considered in the set.

This indicates that 3 and 5 are out. We are left with only one even number, four.

As a result, the set of odd integers between 3 and 5 is a Null Set (it contains no numbers).

The value of X=8 when the bases have lengths of 2x+4 and 8x-50

A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are called the bases of the trapezoid. The nonparallel sides are referred to as the legs of the trapezoid.

A median of a trapezoid is the segment that joins the midpoints of the nonparallel sides (legs). The median is also parallel to the two bases, and it is the average length of the two bases.

The formula to find the median is

median=a+b/2

where a and b are the lengths of the bases or parallel sides.

we have the values of a=2x+5 b=8x-50 m=17 now substitute the values in the above formula and we get x value:

Answer:

I guess, A is the wanted answer, but

A and D together are the really correct answer.

Step-by-step explanation:

if I understand this correctly, then

g(x) = sqrt(x - 3)

the domain of a function is the definition of all valid x (input) values.

the range of a function is the definition of all valid y (result) values.

well, the content (the arguments) of a square root cannot be negative (at least not while dealing with real numbers).

so, the answer options B and D are automatically out, because the domain contains values that would make the arguments of the square root negative.

I guess your teacher wants to focus only on the positive results of the square root, so A is the correct number.

BUT formally, without designated restrictions, a square root has always 2 solutions : a positive and a negative one.

because (-x)² = (x)² = x².

so, I would have to say that the really correct answer is

A + D, because the range contains both, the positive and the negative numbers.

Any square-free integer can be expressed as the product of a square-free integer (which has no square  factors) and a perfect square (which has only square factors). This product is unique for any given square-free integer.

Any square-free integer can be expressed as the product of a square-free integer and a perfect square. This is because a square-free integer has no square factors, so the product of a square-free integer and a perfect square would have only square factors, and thus be square-free. To show that this product is unique for any given square-free integer, we can use the fact that any integer can be expressed as the product of its prime factors and that a square-free integer has no square factors. This means the prime factors of the square-free integer are all distinct, and thus the product of the square-free integer and the perfect square can be expressed as the product of the prime factors of the square-free integer and the prime factors of the perfect square. Since the prime factors of the perfect square are all the same, the product is uniquely determined by the prime factors of the square-free integer. Thus, the product of a square-free integer and a perfect square is unique for any given square-free integer.

Therefore , the solution of the given problem of probability comes out to be  probability of  not experiencing either symptom is 0.05.

Calculating the likelihood that a statement is true or that an event will take place is the focus of probability theory, a branch of mathematics. Any number range between 0 and 1, where 1 is frequently used to describe certainty and 0 is commonly used to denote possibility, can be used to represent chance. A probability diagram shows the likelihood that a particular event will occur.

Here,

To determine if the two symptoms are independent, we need to check if the probability of one symptom changes depending on whether the other symptom is present or not.

P(pain | swelling) = 40% / 75% = 0.533

P(pain | no swelling) = 20% / 25% = 0.8

Since the conditional probabilities are not equal, the two symptoms are dependent.

(c) The probability that the victim will experience at least one of these symptoms is the probability of experiencing pain, swelling, or both. This can be calculated as:

P(pain or swelling) = P(pain) + P(swelling) - P(pain and swelling)

= 60% + 75% - 40%

= 95%

So the probability of experiencing at least one of these symptoms is 95%.

(d) The probability that a victim will have intense pain given that they have swelling is the conditional probability:

P(pain | swelling) = 40% / 75%

= 0.533

So the probability of having intense pain given that there is swelling is 0.533.

(e) The probability that a victim will experience pain but not swelling can be calculated as:

P(pain and no swelling) = P(pain) - P(pain and swelling)

= 60% - 40%

= 20%

So the probability of having intense pain without swelling is 20%.

(f) The probability that a victim will not experience either symptom is the complement of the probability of experiencing at least one symptom:

P(neither pain nor swelling) = 1 - P(pain or swelling)

= 1 - 0.95

= 0.05

So the probability of not experiencing either symptom is 0.05.
