The explanation about counterexample for the conjecture is describe below.

The term counterexample alludes to an occasion or model that offers the expression bogus. This is utilized in rationale to check in the event that an assertion is valid or not. Counter model will quite often counter the explanation being talked about with admirable sentiments.

The inquiry needs to show the relationship that might exist among perimeter and area of a rectangle.

The counterexample gave the aspects that gave the border which is 40 however neglected to give area of 1 square unit

Thus, A rectangle with length 19.99 units and width 0.01 unit has a perimeter of 40 units and an area of 0.1999 square unit.

The most common error when entering a formula is to reference the wrong cell in the formula.

This error occurs when the cell references within a formula do not match the intended cells. It can lead to incorrect calculations and produce unexpected results. For example, if a formula is supposed to use data from cell A1 but mistakenly refers to cell B1, the calculation will be based on the wrong data. It is important to double-check and ensure that the cell references in a formula accurately reflect the intended data sources to avoid this common mistake.

The mean and standard deviation of the total time are µx = 66 and σx = 3.17, so the correct answer is (D) µx= 66 σx= 3.17.

To find this:

The total time to complete all three tasks is the sum of the time taken for each task. The mean time to complete all three tasks (µx) can be calculated by adding the mean time for each task: µx = 36 + 22 + 8 = 66. The standard deviation (σx) of the total time can be calculated using the standard deviation of each task and the square root of the number of tasks (n).

Using the formula: \(\sigma x = \frac{\sqrt{\sigma1^2 + \sigma2^2 + \sigma3^2}}{\sqrt n}\),

where σ1, σ2, σ3 are the standard deviations of each task, n = 3.

Plugging in the values, we get

\(\sigma x = \sqrt(2.5^2 + 1.8^2 + 0.75^2)/\sqrt3 \\= \sqrt{6.25 + 3.24 + 0.5625}/\sqrt3 \\= \sqrt{10.0525}/\sqrt3 = 3.17\)

Hence, the mean and standard deviation of the total time are µx = 66 and σx = 3.17, so the correct answer is (D) µx= 66 σx= 3.17.

Answer:

Step-by-step explanation:

We can use trigonometry to solve this problem. Let's draw a right triangle to represent the situation:

        |\

        | \

   h    |  \   9 ft

        |   \

        |    \

        |     \

        -------

        6 ft

Here, h represents the height on the wall where the ladder touches. We want to find the angle of elevation θ.

Using the right triangle, we can write:

sin(θ) = h / 9

cos(θ) = 6 / 9 = 2 / 3

We can solve for h using the Pythagorean theorem:

h^2 + 6^2 = 9^2

h^2 = 9^2 - 6^2

h = √(9^2 - 6^2)

h = √45

h = 3√5

So, sin(θ) = 3√5 / 9 = √5 / 3. We can solve for θ by taking the inverse sine:

θ = sin^-1(√5 / 3)

θ ≈ 37.5 degrees

Therefore, to the nearest tenth of a degree, the angle of elevation the ladder makes with the ground is 37.5 degrees.

Answer:

D. x^2-x-9-12/x-2

Step-by-step explanation:

We can use synthetic division to divide (x^3 - 3x^2 - 7x + 6) by (x - 2). First, we set up the division as follows:

    2 |   1   -3   -7    6

       |______2___-2__-18

       | 1   -1   -9  -12

The numbers on the bottom row of the synthetic division table represent the coefficients of the quotient polynomial. Therefore, the quotient is x^2 - x - 9, and the remainder is -12.

So, we have:

(x^3 - 3x^2 - 7x + 6) / (x - 2) = x^2 - x - 9 + (-12 / x - 2)

Therefore, the correct option is D: x^2 - x - 9 - 12/(x - 2).

The equation of a given situation:

                  2x - 157 = 755

Dave Winfield has 465 home runs.

Hank Aaron has 157 runs fewer than twice the runs that Dave Winfield has.

Hank Aaron hits 755 home runs.

Assume that Dave Winfield has X runs.

The equation is 2x - 157 = 755 --------------------------- (1)

solving the equation (1),

    2x - 157 = 755

⇒ 2x = 755 + 157

⇒ 2x = 912

⇒ x = 456

∴ Dave Winfield has 465 home runs.

If it is arithmetic, find the common difference d; if it is geometric, find the common ratio r then thehe given sequence {3n - 5} is arithmetic, with a common difference of 3.

To determine whether the given sequence is arithmetic, geometric, or neither, we need to look at the pattern of the numbers. For an arithmetic sequence, there is a constant difference between each term. For example, in the sequence 2, 5, 8, 11, 14, the difference between each term is 3.

For a geometric sequence, there is a constant ratio between each term. For example, in the sequence 2, 6, 18, 54, 162, the ratio between each term is 3. Looking at the given sequence {3n - 5}, we can see that there is a common factor of n, which makes it a bit tricky to determine the pattern. However, we can still try to find a common difference or ratio by looking at the differences between terms.

Starting with the first two terms:
n=1: 3(1) - 5 = -2
n=2: 3(2) - 5 = 1

The difference between these terms is 3.
Continuing on:
n=3: 3(3) - 5 = 4
n=4: 3(4) - 5 = 7
The difference between these terms is also 3.
So we can conclude that the sequence is arithmetic, with a common difference of 3.

The required coordinate of the point N is (-5, -1). Option b is correct.

Given that,
Segment MN is drawn in the coordinate plane. Point M has coordinates (13,9) and the midpoint of MN is the point (4.4). What are the coordinates of point N to be determined.

Coordinate, is represented as the values on the x - axis and y - axis of the graph

Let the coordinate of point N is (x, y).
Here, point M has coordinates (13,9) and the midpoint of MN is the point (4.4).

The Coordinate of the midpoint is given as,
(4 = (x + 13)/2, 4 = (y + 9 )/2)

The first step to graph the solution to the system of equations given is option D. Change the inequalities to equalities and solve the resulting system of linear equations.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

1. Given system of inequalities are,

y ≥ x + 3

x < −2

In order to graph the solution, first we have to change the inequality symbols to equality and solve the resulting system of linear equations.

That is, solve y = x + 3 and x = -2

2. The equations of the given line are

y = x - 3

y = -2x

Take the linear equation y = x - 3.

The solution region of both contains the point (-1, 0).

0 = -1 - 3 = -4, correct inequality is 0 ≥ 4.

So the inequality is y ≥ x - 3.

Consider y = -2x

0 = 2, correct inequality is 0 ≤ 2.

So the inequality is y ≤ -2x.

Hence the system of inequalities shown in the graph are option B. y ≥ x - 3 and y ≤ -2x.
