5x/4 means that for every time x increases by 1, y increases by 5/4.

5/4 is the coefficient for x.

Answer:

[tex]\dfrac{5}{4}[/tex]

Step-by-step explanation:

The general slope-intercept form of a line equation is

[tex]y = mx + b[/tex]

where m is the slope and b the y-intercept

The given line has the equation:
[tex]y = \dfrac{5}{4}x - \dfrac{7}{4}[/tex]

Implementing a new system into an organization module by module is called a​ phased approach.

A phased approach is one of two common methods used to develop an ERP system solution. In this strategy, the system's functionalities are introduced in a certain order, gradually replacing previous systems and processes.

This frequently indicates that a business starts off with core functionality that is given top attention, and then other applications are gradually added in stages over time. An alternative implementation strategy, however, uses an all-at-once model in which the system and all apps "Go Live" simultaneously.

The optimal implementation plan for your firm will depend on the needs, goals, and strategies you have for it. This might involve a hybrid strategy where crucial functionality is added to the core ERP programs first, and then desirable features are added later on in a staged implementation. By considering all of your options, your firm can decide which will serve its interests the most effectively.

The equation of the line passing through the points (1,3) with slope = -4 is

y = -4x + 7

The equation of a line can be formed with the help of the slope of the line and a point on the line. The slope of the line is the inclination of the line with the positive x-axis and is expressed as a numeric integer, fraction, or the tangent of the angle it makes with the positive x-axis. The point refers to a point in the coordinate system with the x coordinate and the y coordinate.

m = (y - y1) / (x - x1)

where m = -4

y1 = 3

Answer:

b = 2sqrt(5)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

4^2 + b^2 = 6^2

16+b^2 = 36

b^2 = 36-16

b^2 = 20

Taking the square root of each side

sqrt(b^2) = sqrt(20)

b = sqrt(20)

b = sqrt(4*5)

b = sqrt(4) sqrt(5)

b = 2sqrt(5)

b = 2sqrt(5)

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

4^2 + b^2 = 6^2

16+b^2 = 36

b^2 = 36-16

b^2 = 20

Taking the square root of each side

sqrt(b^2) = sqrt(20)

b = sqrt(20)

b = sqrt(4*5)

b = sqrt(4) sqrt(5)

Point estimate from the sample is 0.985, margin error is 0.003.

Confidence interval is defined as the interval which is the estimate for the parameter of the sample or population to be contained.

(a) To calculate point estimate or sample mean :

Point estimate is the mid point of the confidence interval.

Given that true mean weight of candy bars is 0.982 ounces to 0.988 ounces.

Point estimate = (0.982 + 0.988) / 2 = 1.97 / 2 = 0.985

(b) Margin error is the one half of the total width of the interval.

Margin error = (0.988 - 0.982) / 2 = 0.003

(c) The confidence level of 90% in this problem can be interpreted as , if we do the interval construction for many times, about 90% of the total constructed intervals has the true population mean of weight of fun size candy bars.

We have been given a sequence of numbers 99, 33, 11, 11/3, 11/9,. . .

A cylindrical basin is 2 feet tall and has a diameter of 5 feet, as shown. If the basin is completely filled with water, how much water will it hold? Round the answer to the nearest tenth of a foot.

The basin holds 39.3 cubic feet of water.

The volume of a cylinder is the number of unit cubes (cubes of unit length) that can be fit into it. It is the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it. The volume of a cylinder is measured in cubic units such as cm3, m3, in3, etc. Let us see the formula used to calculate the volume of a cylinder. We know that the base of a right circular cylinder is a circle and the area of a circle of radius 'r' is πr2. Thus, the volume (V) of a right circular cylinder, using the above formula, is,

V = πr²h

Here,

⇒ 'r' is the radius of the base (circle) of the cylinder

⇒ 'h' is the height of the cylinder

⇒ π is a constant whose value is either 22/7 (or) 3.142.

Thus, the volume of cylinder directly varies with its height and directly varies with the square of its radius. i.e., if the radius of the cylinder becomes double, then its volume becomes four times.

We are given that the height of the basin h = 2 ft and the diameter = d = 5 ft.

So, radius r = d/2 = 5/2 = 2.5 ft

The amount of water the basin holds is equal to the volume of cylindrical basin.

Volume =πr²h

=3.1416×2.5²×2

=39.27 cubic feet

= 39.3 cubic feet

Thus, the basin holds 39.3 cubic feet of water.

Given that, the sides of a rectangle are in the proportion 9:14 and the perimeter of the rectangle is 230 cm

Let the smaller side of the rectangle be 9x and larger side be 14x

We know that the perimeter of a rectangle = 2(l+w)

Therefore, perimeter = 2(9x+14x)

2(9x+14x) = 230

2×23x = 230

Step-by-step explanation:

       We know that the angles of a triangle are equal to 180 degrees when added together. Using this logic, we will create an equation to solve for x. Then we will substitute this value of x back into the expression for angle F.

   Given:

E + D + F = 180°

   Substitue:

(8x - 18)° + (6x - 4)° + (5x - 7)° = 180°

   Reorder and combine like terms:

8x° + 6x° + 5x° - 18° - 4° - 7° = 180°

19x° - 29° = 180°

   Add 29 to both sides of the equation:

19x° = 209°

   Divide both sides of the equation by 19:

x = 11

   Substitute this value of x into the expression for angle F:

(5x - 7)°

Here are a few tips for quickly dividing large numbers and decimals:

Use estimation: Estimate the quotient by rounding the dividend and divisor to easy numbers. This can save time and give you a rough idea of the answer.

Use long division: This method can be used to divide larger numbers, and it involves breaking down the dividend into smaller parts, dividing each part by the divisor, and then combining the results.

Use a calculator: A calculator can quickly divide large numbers and decimals, and it eliminates the need for long division or estimation.

Use the reciprocal: Dividing by a number is the same as multiplying by its reciprocal, so if you know the reciprocal of the divisor, you can use it to quickly divide any number.

Use mental math: If you are comfortable with mental math and good at it, you can use it to quickly divide numbers. This can help you to quickly divide large numbers and decimals.

Use the method of repeated subtraction or shifting the decimal point: Instead of dividing by repeatedly subtracting the divisor from the dividend or shifting the decimal point, this method can also be used to divide large numbers and decimals.

Practice: The more you practice dividing large numbers and decimals, the better and faster you will get at it.
