I NEED THE ANSWER TO A

Answer: Yes

Step-by-step explanation:

To determine whether three lengths can form a triangle, we need to check if the sum of the two smaller lengths is greater than the largest length.

Let's order the given lengths from smallest to largest:

14yd, 19yd, 31yd

Now, we can check if the sum of the two smaller lengths (14yd and 19yd) is greater than the largest length (31yd):

14yd + 19yd = 33yd

Since 33yd is greater than 31yd, we know that the three lengths can form a triangle.

Therefore, the answer is yes, 31yd, 14yd, and 19yd can form a triangle.

Answer:

$94.05

Step-by-step explanation:

Original price of jeans=$95

Discount=10%

New price=(100% - 10%) of $95

=90% × 95

=90/100 × 95

=0.9 × 95

=$85.5

Sales tax of 10%

10% of the new price

=10/100 × 85.5

=0.1 × 85.5

=$8.55

Sales tax =$8.55

Total amount paid for the jeans= sales tax + new tax

=$8.55 + $85.5

=$94.05

For the 4 night at the hotel, the answer is 290 since you insert 4 in where the x should be 150+35(4). For the second question, the answer is 8 since you subtract the money you have (430) by the parking cost (150). This lead to 280 and you divide it by the amount you need to spent on hotel charge per night (35) and you get 8. That means that you can spend 8 night at the hotel.

The observed frequencies are variables as they vary from sample to sample. The expected frequencies are not variables as they are determined by the sample size and the distribution in the null hypothesis.

The observed frequencies are variables because they can vary from sample to sample.

In statistical analysis, observed frequencies represent the actual frequencies or counts of events or occurrences observed in a sample.

These frequencies are obtained through data collection and can differ between different samples due to random sampling variability.

Therefore, the observed frequencies are considered as variables that can change from one sample to another.

On the other hand, the expected frequencies are not variables. They are determined by the sample size and the distribution assumed in the null hypothesis.

Expected frequencies are the frequencies that would be expected under the assumption of a particular statistical model or hypothesis.

These frequencies are calculated based on the expected proportions or probabilities predicted by the null hypothesis and the sample size.

Once the sample size and the distribution in the null hypothesis are determined, the expected frequencies become fixed values and do not vary across different samples.

They provide a baseline against which the observed frequencies can be compared to assess the agreement between the observed data and the expected distribution.

In summary, the observed frequencies are considered variables as they vary from sample to sample, while the expected frequencies are not variables but are determined by the sample size and the distribution assumed in the null hypothesis.

Answer:

Ok to make this easier for us we should switch these equations into y=mx+b so that it's easier for us to identify the slope and y-intercept:

to switch into y=mx+b form do this:

3x-y=5

-y=5-3x

y=-5+3x

y=3x+(-5)

2y-15x=8

2y=8+15x

y=4+7 1/2x

y=7 1/2x+4

THe slope of any line in y=mx+b form is m. Therefore in this equation:

y=3x+(-5)     3 is the slope

The y intercept of any line is the +b:

y=7 1/2x+4 -therefore 4 in this equation is our y intercept.

Now we can construct our equation in y=mx+b then into standard form (Ax+By=C)

since 3 is our slope and 4 is our y intercept the equatuon is :

y=3x+4

NOw all we need to do is move this into standard form:

y=3x+4

-3x+y=4

-3x+y=4 is your final answer

Answer: 8 feet.

Step-by-step explanation:

we can see by the first example that the shadow is 1/2 of the height of the original object. so, we just double the height of the shadow to determine the height of the object.

we are asked to solve a system of inequalities that reads:

18 + 2 x < 12

5 x + 2 >= - 18

so we solve for x in each one:

18 + 2 x < 12

subtract 18 from boths sides:

2 x < 12 - 18

2 x < - 6

divide by 2 both sides:

x < - 3

5 x + 2 >= - 18

subtract 2 from both sides:

5 x >= - 20

divide both sides by 5:

x >= -4

so this tells us that we want x values larger than or equal to -4 and x values smaller than -3.

So, please allow me to plot these two sections and see if there is an intersection of both sets:. The graphing can take a little time, so please be patient.

Notice that we have highlighted in green the section of the number line with x-values to the RIGHT of -4 (and also including the "-4" point with a "solid dot".

On the other extreme of this segment we see an "empty dot" at the point -3 on the number line. In this case we are NOT including the value "-3" as per the inequality that asks for x numbers strictly smaller than -3 (so to the left of "-3" NOT including "-3" (represented by the empty dot.

So the graph of the compounded inequality is given above, and the mathematical way to express it is:

- 4 <= x < - 3

Answer: x = -9

Step-by-step explanation:

3x + 2x = 5x

7x + 5 - 5 = 5x - 13 - 5

Subtract 5 from both sides

7x + 5 - 5 = 5x - 13 - 5

simplify

7x = 5x - 18

Subtract 5x from both sides

7x - 5x = 5x -18 - 5x

simplify

2x = -18

divide both sides by 2

\(\frac{2x}{2}\) = \(\frac{-18}{2}\)

simplify

x = -9

The reduced ratio of butter to flour in this recipe is 10:13, or 10⁄13 in fraction form.

The reduced ratio for the quantity of butter to the quantity of flour in this recipe can be found by dividing both quantities by their greatest common factor. The greatest common factor of 30 and 39 is 3, so we can divide both quantities by 3 to get the reduced ratio:

30 ounces of butter ÷ 3 = 10 ounces of butter
39 ounces of flour ÷ 3 = 13 ounces of flour

Finally, the ratio is defined as:

R = butter / flour

R = 10:13 = 10/13

Therefore, the reduced ratio is 10:13, or 10/13 in fraction form.

A better guess for y_p would be a polynomial of degree 2 times e^x. So, y_p = (1/2)x^2 e^x.

the general solution to the differential equation is:

y = c1 e^x + c2 xe^x + y_p

To solve the differential equation y''-2y'+y = e^x, we first need to find the characteristic equation. The characteristic equation is obtained by assuming that y takes the form of an exponential function, y = e^(rx), where r is a constant.

Substituting this expression for y into the differential equation, we get:

r^2 e^(rx) - 2r e^(rx) + e^(rx) = e^x

Simplifying this equation by factoring out e^(rx), we get:

(e^(rx))(r^2 - 2r + 1) = e^x

(r-1)^2 = e^x / e^(rx)

(r-1)^2 = e^(x-rx)

Taking the square root of both sides, we get:

r - 1 = ± e^(x/2 - rx/2)

Solving for r, we get:

r = 1 ± e^(x/2 - rx/2)

Therefore, the general solution to the differential equation is:

y = c1 e^x + c2 xe^x + y_p

where c1 and c2 are constants, and y_p is the particular solution.

To find y_p, we can use the method of undetermined coefficients. Since e^x is already part of the complementary solution, we try y_p in the form of Ae^x.

Substituting y_p = Ae^x into the differential equation, we get:

Ae^x - 2Ae^x + Ae^x = e^x

Simplifying, we get:

-Ae^x = 0

This equation has no solution unless A = 0. However, this would result in y_p = 0, which is already part of the complementary solution. Therefore, we need to modify our guess for y_p.

A better guess for y_p would be a polynomial of degree 2 times e^x, since the characteristic equation has a repeated root of 1. So, we try y_p in the form of (Ax^2 + Bx + C) e^x.

Substituting y_p into the differential equation, we get:

e^x (A(x^2-2x+1) + B(2x-2) + 2A(x-1) + 2Bx + 2C) = e^x

Simplifying, we get:

e^x ((Ax^2 + (2A + B) x + (A + 2B + 2C)) - 2(Ax^2 - 2Ax + A) + (Ax^2 + (2A - B) x + (A - 2B + 2C))) = e^x

Simplifying further, we get:

e^x ((3A - B) x + 2B + 4C) = e^x

Equating the coefficients of e^x on both sides, we get:

3A - B = 0
2B + 4C = 1

Solving for A, B, and C, we get:

A = 1/2
B = 3/2
C = -1/4

Therefore, the particular solution is:

y_p = (1/2)x^2 e^

Answer: 2+3=5. Are you sure this is a high school question??

Answer:5

Step-by-step explanation:because 3+2=5

To solve a linear system using Gaussian elimination, we need the specific set of linear equations and the number of unknowns in the system.

To write the corresponding set of linear equations for the system, we need more specific information about the system itself.
Without that information, it is not possible to determine the number of unknowns in the system or provide the specific equations.

However, I can explain the general process of using Gaussian elimination to solve a linear system.

Gaussian elimination is a method used to solve a system of linear equations by transforming the system into an equivalent system that is easier to solve.

It involves applying a sequence of elementary row operations to the augmented matrix representing the system.

These operations include swapping rows, multiplying a row by a nonzero constant, and adding a multiple of one row to another row.

The process of Gaussian elimination continues until the augmented matrix is transformed into row-echelon form or reduced row-echelon form.

At this point, the system can be easily solved using back substitution or by reading the solutions directly from the matrix.

If the system has more equations than unknowns, it may have infinitely many solutions.

In this case, we introduce free parameters (such as r, s, t) to represent the variables that can take any value.

Answer:

Given:

time taken by first pipe = 15 hours

time taken by second pipe = 5 hours

time taken by all three pipes together = 3 hours

work rates of pipes are :

1st pipe = 1/15

2nd pipe = 1/5

3rd pipe = 1/x

all together = 1/3

sum of individual rates = rate when all pipes are working together

1/15 + 1/5 + 1/x = 1/3

1/x = 1/3 - 1/15 - 1/5

solving the equation, we get
1/x = 1/ 15

x= 15

hence, it would take 15 hours for the third pipe to fill the tank.

The value of a quantitative variable is expressed as a number when the variable is either discrete or continuous. Quantitative variables are of two types: discrete and continuous. The answer to the question is (d) always.

A variable is said to be discrete if it can only take on a finite number of values; for example, the number of students in a class, the number of cars in a parking lot, or the number of books on a shelf. On the other hand, a variable is said to be continuous if it can take on any value within a certain range; for example, height, weight, or temperature. In both cases, the value of the variable is expressed as a number.

Regardless of whether the variable is discrete or continuous, it is always expressed as a numerical value.
