The linear equation doesn't have a solution.

The linear equation given is illustrated as: 4x-(2x-1) = x+5+x-6

This will be solved thus:

4x - 2x + 1 = x+5+x-6

4x - 2x + 1 = 2x - 1.

2x + 1 = 2x - 1

Collect like terms

2x - 2x = -1 - 1

0 = -2

This illustrates that the equation doesn't have a solution.

Answer:

(5, -3)

Step-by-step explanation:

So the center of the two points, or a line can be defined using the equation: \(midpoint=(\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2})\). So using the two points you gave, you simply plug the values in to get

\(midpoint=(\frac{3+7}{2}, \frac{-1+(-5)}{2})\\\)

Add numerators:

\(midpoint=(\frac{10}{2}, \frac{-6}{2})\)

Simplify fraction:

\(midpoint=(5, -3)\)

The average acceleration of Train A over the interval 2 ≤ t ≤ 8 is -40 meters per minute squared.

Explanation:

The average acceleration of a body over a given time interval is defined as the change in velocity divided by the time interval. In this case, we are given the velocity function vA(t) for Train A, and we want to find its average acceleration over the interval 2 ≤ t ≤ 8.

To find the change in velocity over this interval, we can subtract the velocity at t=2 from the velocity at t=8:

Δv = vA(8) - vA(2) = (-120) - 100 = -220 meters per minute

To find the time interval, we can subtract 2 from 8:

Δt = 8 - 2 = 6 minutes

Now we can use the formula for average acceleration:

a = Δv/Δt = (-220)/6 = -40 meters per minute squared

Therefore, the average acceleration of Train A over the interval 2 ≤ t ≤ 8 is -40 meters per minute squared.

Step-by-step explanation:

The probability that both blue crabs are under 10 inches is approximately 37.4%.

To find the probability that both blue crabs are under 10 inches:

We need to consider the normal distribution, mean, and standard deviation of their body lengths.

The body length of blue crabs follows a normal distribution with a mean of 9 inches and a standard deviation of 3.5 inches.

Step 1: Find the z-score for 10 inches.
z = (X - mean) / standard deviation
z = (10 - 9) / 3.5
z = 1 / 3.5
z ≈ 0.286

Step 2: Look up the z-score in a standard normal distribution table or use a calculator to find the probability associated with the z-score.
P(Z ≤ 0.286) ≈ 0.612

Step 3: Since the lengths of blue crabs are independent, multiply the probability of one crab being under 10 inches by itself to find the probability of both crabs being under 10 inches.
P(both crabs under 10 inches) = P(1st crab under 10 inches) * P(2nd crab under 10 inches)
P(both crabs under 10 inches) = 0.612 * 0.612
P(both crabs under 10 inches) ≈ 0.374

Therefore, the probability that both blue crabs are under 10 inches is approximately 37.4%.

The ratio of cost to the number of cans = 5: 2  

A ratio is a mathematical concept that represents the relationship between two or more values.

In the given problem, the ratio represents the relationship between the cost of the soup and the number of cans purchased.

Ratios are commonly used in mathematics, finance, and other fields to express comparisons and relationships between different quantities.

Here we have

$10 for 4 cans of soup  

The required ratio can be formed as follows

=> 10: 4

=> 10/2: 4/2   [ Divided by 2 ]

=>  5: 2

Therefore,

Answer:

x=6

slope (m) = -3

Step-by-step explanation:

Step-by-step explanation:

we first square both sides to eliminate the square root brackets..

(√(m(y+n)/y)²= p²

m(y+n)/y = p²

(my +mn)/y =p²

so we multiply both sides by y to eliminate the denominator,

(my+mn)/y*y =p²*y

my+mn = p²y

collecting like terms,we have:

mn= p²y-my

so we seperate the y on the right hand side from the rest to have

mn = y(p²-m)

so divided both sides by the value in the bracket on the right hand side we have..

mn/(p²-m)=y(p²-m)/(p²-m)

so we have,

y= mn/(p²-m)

Answer:

y = \(\frac{-mn}{m-p^2}\)

Step-by-step explanation:

Given

\(\sqrt{\frac{m(y+n)}{y} }\) = p ( square both sides )

\(\frac{m(y+n)}{y}\) = p² ( multiply both sides by y )

m(y + n) = p²y ← distribute parenthesis on left side

my + mn = p²y  ( subtract p²y from both sides )

my - p²y + mn = 0 ( subtract mn from both sides )

my - p²y = - mn ← factor out y from each term on the left side

y(m - p²) = - mn ← divide both sides by (m - p²)

y = \(\frac{-mn}{m-p^2}\)

Answer:

a = 15, b = - 14

Step-by-step explanation:

Given the 2 equations

\(\frac{a}{5}\) - \(\frac{b}{2}\) = 10 ( multiply through by 10 to clear the fractions )

2a - 5b = 100 → (1)

a - b = 29 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the a- term

- 2a + 2b = - 58 → (3)

Add (1) and (3) term by term to eliminate a

0 - 3b = 42

- 3b = 42 ( divide both sides by - 3 )

b = - 14

Substitute b = - 14 into (2) and evaluate for a

a - (- 14) = 29

a + 14 = 29 ( subtract 14 from both sides )

a = 15

Answer:

  2(x -4y)(x +4y)

Step-by-step explanation:

Once you factor out the common factor of 2, what remains is the difference of squares. That can be factored further.

The factoring of the difference of squares is ...

  a² -b² = (a -b)(a +b)

Then we have ...

  2x² -32y² = 2(x² -16y²) = 2(x² -(4y)²)

  = 2(x -4y)(x +4y)

L = 14

W = 7

H = 7

Solution

SA = 2*14*7 + 2*14*7 + 2*7*7

SA = 196 + 196 + 98

SA = 490

Answer:

Step-by-step explanation:

The sum of 490 divided by 5 is 98.

To find the sum of 490 divided by 5, we need to perform the division operation and then add up the quotient and the remainder, if any.

When we divide 490 by 5, we get a quotient of 98.

There is no remainder because 490 is evenly divisible by 5. So, the quotient is the whole number result of the division.

To find the sum, we add the quotient and the remainder, if any.

In this case, there is no remainder, so the sum is simply the quotient: 98.

Therefore, the sum of 490 divided by 5 is 98.

C. When there is no outlier, the mean is the appropriate measure of center.

When there are no outliers in a dataset, the mean is a good measure of center because it takes into account the values of all the data points. The median is also a good measure of center, but it may not be the best choice if there are extreme values or outliers in the dataset, as it can be influenced by those values. However, when there are no outliers, both the mean and the median are appropriate measures of center.

Option A is not true because the mean is not skewed in one direction when there is no outlier. Skewness refers to the shape of the distribution, and it can be affected by outliers, but not by the absence of outliers.

Option B is not true because the median is not skewed in one direction when there is no outlier. Skewness refers to the shape of the distribution, and the median is not affected by the shape of the distribution, but by the position of the values.

Option D is not true because the median can be used as the measure of center even when there is no outlier. It is a robust measure of center that is not influenced by extreme values.

Answer: Your answer is completely correct. It is just that when answering the question, you should assume that the 48 lb child is on the left, and the 72 lb child is on the right. Usually, I always assume that the first mentioned item is the left most one.

Step-by-step explanation:

This is how I will set up the problem: M1 = 48 lbs, M2 = 72 lbs, L = 10 ft

Since (M1 * 0 + M2 * 10)/(M1+M2) = equilibrium, we can use this equation to find the solution:

0 + 720 / (48+72) = 6 feet
