The computed value must closely match the real value for a model to be considered valid. If the percentage of pleased or very satisfied students remains close to 75% after Mateo surveys additional students, Mateo's model is still viable. The model is faulty if the opposite is true.

<h3>How will mateo know whether his model is valid or not?</h3>

In general, a valid model is one whose estimated value is close to the real value. This kind of model is considered to be accurate. It must be somewhat near to the real value if it doesn't resemble the real value.

If the findings of the survey are sufficiently similar to one another, then the model may be considered valid.

P1 equals 75%, which is the real assessment of the number of happy pupils

P2 is 70 percent; this represents the second assessment of happy pupils

In conclusion,  The estimated value of a model has to be somewhat close to the real value for the model to be considered valid. If the number of students who are either pleased or extremely satisfied remains close to 75 percent following Mateo's survey of more students, then Mateo's model is likely accurate. In any other scenario, the model cannot be trusted.

Given

piece of plywood measuring 2 feet 8 inches long by 2 feet 4 inches wide.

What is the area of a piece of plywood .

To proof

Here plywood shape in the form of rectangle.

Formula

Area of rectangle = Length×Breadth

As given in the question

Length =2 feet 8 inches

Breadth = 2 feet 4 inches

First convert feet into inches

1 feet = 12 inches

2 feet 8 inches = 2×12 + 8

                       =  32 inches

Also

2 feet 4 inches  = 2×12 +4

                          = 28 inches

Kristel is considering hiring a moving company. Sanford's Plus charges an initial fee of $125 plus $165 per hour. Quality Moving
Anna35 [415]

Let the number of hours be $x

Initial charges by Sanford's Plus = $125

Per hour charges = $165

Total cost of Sanford's Plus company = 125 + 165x

Initial charges by Quality Moving Company = $200

Per hour charges = $145

Total cost of Quality Moving Company = 200 + 145x

If either company were hired for hours, the total cost would be the same

125 + 165x = 200 + 145x

Add -125 on both sides

125 - 125 + 165x = 200 + 145x-125

165x = 75 + 145x

Add -145 on both sides

165x - 145x = 75

20x = 75

Divide both side by 20, to find the value of x

x = 75/20

x = 3.75 hours

Total cost of Sanford's Plus company = 125 + 165x

x = 12 hrs

Total cost of Sanford's Plus company = 125 + 165(12)

Total cost of Sanford's Plus company = 125 + 1980

Total cost of Sanford's Plus company = $2105
