Answer:

numerator degree of freedom = 3

Denominator degree of freedom = 47

Step-by-step explanation:

The numerator degree of freedom is given by :

p - 1 ; where p = number of predictors ;

p = number of independent variables + 1

Number of independent variables = 3

p = 3 + 1 = 4

Numerator degree of freedom = p - 1 = 4 - 1 = 3

The denominator degree of freedom = n - p ; where n = number of observations

Number of observations, n = 51

Denominator degree of freedom = n - p = 51 - 4 = 47

4. A rectangle is inscribed into a circle. The rectangle is cut along one of its diagonals and reflected across that diagonal to
klio [65]

Answer:

The diagrams below explain the process with angles.

Step-by-step explanation:

In figure 1, a rectangle is drawn in the circle.

Since the acute angle being drawn by the hypotenuse is 40 degree in figure 2, thus we can say the other angle will be 50 degrees.

In figure 3, the rectangle is cut across its diagonal to form a kite shaped entity within the circle.

Now we know that m∠BDE = 40° = m∠ADB.

Also, m∠A = m∠E = 90°

Thus, m∠EBD = m∠ABD = 50° ⇒ m∠B = 100°

Also, m∠ADE = 80° ANSWER

It was recently estimated that uninsured vehicles out number insured ones by about 6 to 5 if there are 2002 vehicles in a county
Luba_88 [7]

There are 1092 uninsured vehicles.

Step-by-step explanation:

Given,

Ratio of uninsured vehicles to insured vehicles = 6:5

Let,

x be the original number.

Number of uninsured vehicles = 6x

Number of insured vehicles = 5x

Total vehicles = 2002

6x+5x=2002\\11x=2002

Dividing both sides by 11

\frac{11x}{11}=\frac{2002}{11}\\x=182

Number of uninsured vehicles = 6x = 6(182) = 1092

Number of insured vehicles = 5x = 5(182) = 910

There are 1092 uninsured vehicles.
