Which table does NOT show y as a function of x

Answer:

160+65%=264

Step-by-step explanation:

i think

Answer:

264 inches

Step-by-step explanation:

160/ 0.65 = 104

104 + 160 = 264

Answer:

2.  y = 3x + 6

3.  y = 2x

4.  y = 5x + 60

Step-by-step explanation:

Slope-intercept form: y = mx + b

2.

Pick 2 points (0,6) (1,9)

The y increase by 3, and the x increase by 1, so the slope is

m = 3

the y-intercept is located at (0,6)

Our equation is y = 3x + 6

3.

Pick 2 points (0,0) (1,2)

The y increase by 2, and the x increase by 1, so the slope is

m = 2

the y-intercept is located at (0,0)

Our equation is y = 2x

4.

Pick 2 points (0,60) (2,70)

The y increase by 10, and the x increase by 2, so the slope is

m = 10/2 = 5

the y-intercept is located at (0,60)

Our equation is y = 5x + 60

The correct answer is option c) infinitely many solutions..

To solve the system of equations using the substitution method, we'll substitute the value of y from the second equation into the first equation and solve for x.

Given:

-6x + 2y = 8 ---(1)

y = 3x + 4 ---(2)

Substitute equation (2) into equation (1):

-6x + 2(3x + 4) = 8

Simplify:

-6x + 6x + 8 = 8

8 = 8

We obtained a true statement (8 = 8), which means the two equations are equivalent. This solution shows that the system has infinitely many solutions.

Therefore, the correct answer is option c) infinitely many solutions..

The Bootstrap Method is straightforward and straightforward to comprehend. First, it chooses randomly from the original sample to produce bootstrap samples from our initial sample.

After that, it uses summary statistics like variation, standard deviation, mean, and so on to get replicates, which is how we can calculate a confidence interval from that sample.

Thus, the answer is "Yes."

The bootstrap method is a resampling method that uses replacement sampling to estimate population statistics. It can be used to estimate standard deviation and mean summaries.

Remember that bootstrapping isn't only valuable for computing standard blunders, it can likewise be utilized to build certainty spans and perform speculation testing. When working with data that doesn't seem to lend itself to conventional methods, always remember bootstrapping techniques.

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

The percentage of tires that will have a life of 45,000 to 55,000 miles is  68.27%. So the correct option is 68.27%.

To find the percentage of tires that will have a life of 45,000 to 55,000 miles, we can use the concept of the normal distribution.

First, we calculate the z-scores for both values using the formula:
z = (x - mean) / standard deviation

For 45,000 miles:
z1 = (45,000 - 50,000) / 5,000 = -1

For 55,000 miles:
z2 = (55,000 - 50,000) / 5,000 = 1

Next, we look up the corresponding values in the standard normal distribution table. The table will provide the proportion of data within a certain range of z-scores.

The percentage of tires with a life between 45,000 and 55,000 miles is the difference between the cumulative probabilities for z2 and z1.

Looking at the standard normal distribution table, the cumulative probability for z = -1 is 0.1587, and the cumulative probability for z = 1 is 0.8413.

Therefore, the percentage of tires that will have a life of 45,000 to 55,000 miles is:
0.8413 - 0.1587 = 0.6826

Converting this to a percentage, we get:
0.6826 * 100 = 68.26%

So the correct answer is 68.27%.

To solve the given system of differential equations, we can use the substitution method to obtain first-order linear differential equations and solve them for x and y. Alternatively, we can apply the operator method to rewrite the system as a second-order linear differential equation.

To solve the given system of differential equations using three different methods - substitution method, operator method, and eigen-analysis method - we start by representing the system in matrix form: Let X = [x y]' and X' = [x' y']'. The given system can be written as: X' = A * X + B, where A is the coefficient matrix and B is the vector of constants.

Substitution Method:

In this method, we substitute the expressions for x' and y' from the given system into the equations and solve for x and y. By substituting the given expressions, we obtain two first-order linear differential equations. We can then solve these equations using standard methods such as separation of variables or integrating factors to find the solutions for x and y.

Operator Method:

The operator method involves defining operators D = d/dt and E = d/de, where t is the independent variable and e is the exponential function. We can rewrite the given system as a single second-order linear differential equation in terms of these operators. By manipulating the equations using operator algebra, we can find the characteristic equation and the solutions for x and y.

Eigen-analysis Method:

The eigen-analysis method involves finding the eigenvalues and eigenvectors of the coefficient matrix A. By calculating the eigenvalues, we can determine the type of critical points in the system. The eigenvectors corresponding to the eigenvalues provide the basis for the solutions. Using the eigenvalues and eigenvectors, we can construct the general solution for the system. Lastly, the eigen-analysis method helps us determine the critical points and construct the general solution using eigenvalues and eigenvectors.

The solution to the inequality 2x^2+x-15≤0 is -3≤ x ≤ 5/2.

To solve the inequality 2x^2+x-15≤0, we can use the following steps:

Step 1: Factor the quadratic expression on the left-hand side of the inequality, if possible. In this case, we can factor 2x^2+x-15 as (2x-5)(x+3).

Step 2: Set each factor equal to zero and solve for x. We get 2x-5=0 or x+3=0, which gives us x=5/2 or x=-3.

Step 3: Use these values of x to divide the number line into three intervals: x< -3, -3≤ x ≤ 5/2, and x> 5/2.

Step 4: Choose a test value from each interval and substitute it into the inequality to determine whether the inequality is true or false for that interval. For example, we can choose -4 as a test value from the interval x< -3. When we substitute x=-4 into the inequality, we get 2(-4)^2+(-4)-15=17>0, which means the inequality is false for x< -3.

Step 5: Based on the results of Step 4, we can determine the solution set for the inequality. In this case, the inequality is true for -3≤ x ≤ 5/2, so the solution set is -3≤ x ≤ 5/2.

Answer: (G) -7.3 degrees Celsius

Step-by-step explanation:

To find the temperature at midnight, we need to start with the temperature at 8 P.M. and then add or subtract the temperature changes that occurred between 8 P.M. and midnight.

The temperature change between 8 P.M. and 10 P.M. was +3.9 degrees Celsius, so the temperature at 10 P.M. was:

-6.8 + 3.9 = -2.9 degrees Celsius

The temperature change between 10 P.M. and midnight was -4.4 degrees Celsius, so the temperature at midnight was:

-2.9 - 4.4 = -7.3 degrees Celsius

If a decision maker wishes to reduce the margin of error associated with a confidence interval estimate for a population mean, she can increase the sample size.

The margin of error refers to the statistic measurement that expresses the level of random sampling error in the outcomes of a survey. If the margin of error of the result is high, the confidence level would be low that a result reflects the census of the entire population. It indicated the difference between the actual and estimated results in a random survey sample. The margin of error is generally used in non-survey contexts to show observational error in reporting measured quantities. In order to minimize the margin of error associated with a confidence interval estimate for a population mean, the researchers can increase the sample size to capture the actual trend of the population more accurately.
