.....

The vertex form of the equation is y = (x - 3)² - 4, which corresponds to option OD.

To convert the given equation from standard form to vertex form, we need to complete the square.

The vertex form of a parabola's equation is y = a(x-h)² + k, where (h, k) represents the vertex of the parabola.

Given equation: y = x² - 6x + 14

Move the constant term to the right side:

y - 14 = x² - 6x

Complete the square by adding and subtracting the square of half the coefficient of x:

y - 14 + 9 = x² - 6x + 9 - 9

Group the terms and factor the quadratic:

(y - 5) = (x² - 6x + 9) - 9

Rewrite the quadratic as a perfect square:

(y - 5) = (x - 3)² - 9

Simplify the equation:

y - 5 = (x - 3)² - 9

Move the constant term to the right side:

y = (x - 3)² - 9 + 5

Combine the constants:

y = (x - 3)² - 4

Example 1: m < n Matrix A: 3x4

Example 2: m > n Matrix B: 4x3

For non-square matrices, the determinant is not defined, so det = 0 in Example 2.

consider two matrices, one with m < n and the other with m > n.

Example 1: m < n

Suppose we have a matrix A with dimensions 3x4:

A = [[1, 2, 3, 4],

    [5, 6, 7, 8],

    [9, 10, 11, 12]]

In this case, m = 3 and n = 4. The matrix A has more columns than rows.

Example 2: m > n

Now let's consider a matrix B with dimensions 4x3:

B = [[1, 2, 3],

    [4, 5, 6],

    [7, 8, 9],

    [10, 11, 12]]

Here, m = 4 and n = 3. The matrix B has more rows than columns.

Regarding your second question, the determinant (det) of a matrix is defined only for square matrices, i.e., matrices with the same number of rows and columns (m = n). If the matrix is not square, the determinant is not defined, and we say det = 0.

In the second example, matrix B is not square (m > n), so its determinant is automatically 0. This is a general property of non-square matrices.

Answer:

The linear equation is y = 450 - 30 x, where y is the number of pages

Lourdes has left to read after x days

Step-by-step explanation:

Each day, Lourdes reads 30 pages of a 450-page book

- We need to write a linear equation to represent the number of pages

 Lourdes has left to read after x days

∵ Lourdes reads 30 pages each day

∵ Lourdes will read for x days

∴ The number of pages Lourdes will read in x day = 30 x

- The left pages will be the difference between the total pages of the

 book and the pages Lourdes read

∵ The book has 450 pages

∵ Loured will read 30 x in x days

∴ The number of pages left = 450 - 30 x

- Assume that y represents the number of pages Lourdes has left

 to read after x days

∴ y = 450 - 30 x

The linear equation is y = 450 - 30 x, where y is the number of

pages Lourdes has left to read after x days

Answer:

Step-by-step explanation:

Answer:

y = - \(\frac{5}{3}\)

Step-by-step explanation:

6x - 3y = - 7 → (1)

2x + 3y = - 9 → (2)

multiplying (2) by - 3 and adding to (1) will eliminate x

- 6x - 9y = 27 → (3)

add (1) and (3) term by term to eliminate x

0 - 12y = 20

- 12y = 20 ( divide both sides by - 12 )

y = \(\frac{20}{-12}\) = - \(\frac{5}{3}\)

Answer:

Step-by-step explanation:

\(x = \frac{68}{13}\)

\(y = \frac{1}{13}\)

To solve the system of equations by substitution method, we can use one equation to solve for x or y, and then substitute that expression into the other equation to solve for the other variable.

From the second equation, we have:

x - 3y = 5

Solving for x, we get:

x = 3y + 5

Now we can substitute this expression for x into the first equation and solve for y:

2x + 7y = 11

2(3y + 5) + 7y = 11

6y + 10 + 7y = 11

13y = 1

y = 1/13

Now that we have solved for y, we can substitute this value back into one of the original equations to solve for x:

x - 3y = 5

x = 3y + 5

x = 3(1/13) + 5

x = 5 6/13

Therefore, the solution to the system of equations is:

x = 5 6/13 and y = 1/13.

The probability that a student chosen at random has a cat or a dog is; P(cat or dog) = 22/25.

What is probability?

Probability is that the branch of arithmetic regarding numerical descriptions of however probably an incident is to occur, or however probably it's that a proposition is true. The likelihood of an incident could be a range between 0 and 1.

Main body:

According to the question, the total number of students is; 25.

15 of them have a cat

16 of them have a dog

while, 3 of them have neither

where, x = number if students who own a cat and a dog.

Consequently, the total number of students who own a cat, a dog, both or neither is as follows;

15-x + x + 16-x + 3 = 25.

-x = 25 - 34

In essence, x = 9

the number of students who own a cat and a dog is 9.

Therefore, probability that a student chosen at random has a cat and a dog is therefore;

P(cat and dog) = 9/25.

Therefore probability that a student chosen at random has a cat or a dog is 22/25.

A car travel 20kph faster than a truck. the car cover 350 km in two hours less than the time. The speed of the car is 50 km/h. The speed of truck is 70 km/h.

You can determine an object's speed if you know how far it moves in a given amount of time. For instance, an automobile is moving at a pace of 70 miles per hour if it covers 70 miles in an hour (miles per hour).

Given,

A car travel 20kph faster than a truck. the car cover 350 km in two hours less than the time.

Let s represent the truck's speed and (s+20) represent the car's speed.

to determine each vehicle's time

Time = Speed / Distance

truck time = 350/s

Time in an automobile is 350/(s+20)

Truck time - car time = 2 hours

So,

(350/s) - [350/(s+20)] = 2

LCM is s(s+20)

[350(s+20) - 350s]/s(s+20) = 2

Cross multiplying,

350(s+20) - 350s = 2s(s+20)

Simplifying the equation,

350s + 7000 - 350s = 2s² + 40s

Now, we have quadratic equation to simplify,

2s² + 40s - 7000 = 0

Dividing the equation by 2

s² + 20s - 3500 = 0

Factorizing,

s= 50

s= -70 (impossible because of the sign)

Hence the truck's speed is s = 50 km/h.

The speed of the car is s + 20 = 70 km/h.

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

there is no common factor between 23 and 12, since 23 is a prime number. Therefore, we cannot simplify 23/1 to get an equivalent fraction with a denominator of 12.

It is not possible to create a fraction with a denominator of 12 that is equivalent to 23.

To understand why, we can look at the definition of equivalent fractions. Two fractions are equivalent if they represent the same value. This means that if we can simplify one fraction to get the other, then they are equivalent.

In this case, we have the fraction 23, which can be written as the improper fraction 23/1. To find an equivalent fraction with a denominator of 12, we need to simplify 23/1 by dividing both the numerator and denominator by a common factor until the denominator becomes 12.

Supporting Question and Answer:

How do we construct a confidence interval for the mean using the t-distribution?

To construct a confidence interval(CI) for the mean using the t-distribution, we need to know the sample mean, sample standard deviation (or sum of squared deviations), sample size, and the desired confidence level. By calculating the standard error, determining the critical value from the t-distribution table, and multiplying it by the standard error, we can find the margin of error. Finally, we construct the confidence interval for the mean using the t-distribution.

Body of the Solution: To find the 95% confidence interval for the mean response time of the fire station in the northern part of town, we can use the t-distribution because the sample size is relatively small and the population standard deviation is unknown.

The sample mean for the northern fire station is given as 192, and the sum of squared deviations is 197.2. The sample size for the northern fire station is 30.

Using the t-distribution, the critical value for a 95% confidence level and a sample size of 30 - 1 = 29 degrees of freedom is approximately 2.045 (obtained from a t-table or calculator).

To calculate the standard error (SE) of the mean using the formula:

SE = sqrt(Sum of Squared Deviations / (n × (n - 1)))

For the northern fire station:

SE = sqrt(197.2 / (30×(30 - 1))) ≈ 0.3176

E = Critical Value× SE

= 2.045 ×0.3176

≈ 0.6493

To construct the 95% confidence interval, we add and subtract the margin of error from the sample mean:

Lower Bound  = 192 - 0.6493

≈ 191.35

Upper Bound = 192 + 0.6493

≈ 192.65

Therefore, the 95% confidence interval for the mean response time of the fire station in the northern part of town is approximately 191.35 to 192.65 minutes.

Blank #1: 95% confident that the true mean response time of the fire station in the northern part of town is between 191.35 and 192.65 minutes.

Blank #2: The answer would be (3) yes, the distribution is only slightly skewed, and the sample size is large enough.

Final Answer: Therefore, the 95% CI for the mean response time of the fire station in the northern part of town is approximately 191.35 to 192.65 minutes and the distribution is only slightly skewed, and the sample size is large enough.
