Answer:
d). 14 and 240
Step-by-step explanation:
According to the Question,
- Given that, The regression model involving 14 independent variables and 255 observations
We need to find out the numerator and denominator freedom degrees
,
k = 14 regression variable
= n - k - 1
= 255 - 14 - 1
= 240 residuals
df=14,240
-
Now The degree of freedom for F-critical is
F_{k,n-k-1}=F_{14,240}
So, The df of the numerator is 14 and df of the denominator is 240
Answer:
The length of the ladder is 14.5 ft
Step-by-step explanation:
For a right triangle
sinx = opposite / hypotenuse
Since we know the angle and the opposite side, we can calculate the hypotenuse
sin 64 = 13/ hypotenuse
Multiply each side by the hypotenuse
hypotenuse * sin 64 = 13
Divide by sin 64
hypotenuse = 13/sin 64
hypotenuse=14.4638
Rounding to the nearest tenth
14.5
Answer:
90
Step-by-step explanation:
The formula for finding the perimeter of a quadrilateral is Length + Length + Width + Width.
<h3>What is Perimeter?</h3>
- A perimeter is the path that surrounds a certain shape. To calculate the path that surrounds a quadrilateral, we need to get the sum of its four sides, both lengths and widths, lengths being the longest sides and the widths being the shortest.
- The formula used for calculating perimeter is Perimeter = Length + Length + Width + Width.
- For instance, to calculate the perimeter of a parallelogram with a side of 5 cm and one of 3 cm, we insert the numbers in their corresponding spot in the formula as such: Perimeter=5+5+3+3=16 cm or since parallelograms have 2 sets of 2 equal sides, we can use this formula Perimeter=(5×2)+(3×2)=10+6=16 cm.
- For a square on the other hand, we only need to know the length of one side because it has 4 equal sides.
Therefore, the formula for finding the perimeter of a quadrilateral is Length + Length + Width + Width.
