Answer:
The degree of freedom = 16
Step-by-step explanation:
In conducting hypothesis tests where the population standard deviation isn't known, the t-distribution is used to obtain critical value and p-value of the distribution.
To use the t-distribution, the degree of freedom of the test is usually required.
The degree of freedom refers to the maximum number of independent variables, values or parameters, that are allowed to vary in the sample data.
The degree of freedom for a paired test with the same sample size for the two pairs, is given mathematically as
df = n - 1
where n = Sample size = 17
df = 17 - 1 = 16
Hope this Helps!!!
I believe that the correct answer to this is 2,905.81
<span>choices....
a. csc = 15/12
sec = 15/9
b. csc = 15/12
sec = 12/15
c. csc = 9/15
sec = 12/15
d. csc = 9/12
sec = 9/15
a = 9 ; b = 12 ; c = ?
Pythagorean theorem: a</span>² + b² = c²
9² + 12² = c²
81 + 144 = c²
225 = c²
√225 = √c²
<span>15 = c
CSC = cosecant function = hypotenuse/opposite = 15/12
SEC = secant function = hypotenuse/adjacent = 15/9
Choice A: </span><span>csc = 15/12 sec = 15/9 </span>
The area of a rectangle is obtained through the equation,
A = L x W
The width of the yard is 4 ft less than the length and may be expressed as L - 4. Length may be solved through the following steps,
A = (L)(L-4) ; 96 = L(L - 4) ; L = 12 ft
The length and width are 12 ft and 8 ft, respectively. Perimeter may be solved through the equation,
P = 2 x (L + W)
Substituting the values of L and W
P = 2 x ( 12 ft + 8 ft) = 40 ft
Therefore, the perimeter of the yard is 40 ft.
