Answer:
a. 3 and 56, respectively.
Step-by-step explanation:
The computation of the degrees of freedom for the numerator and denominator for the critical value of F is given below:
k = 4
n = 15
Total degree of freedom is
= nk - 1
= 59
For numerator, it is
= k -1
= 4 - 1
= 3
and for denominator it is
= T - (k -1 )
= 59 - 3
= 56
Answer:
<u>There are 200 animals, and the cost is $8,000 daily</u>
Step-by-step explanation:
y=f(x) represents the cost in thousands
x is the number of animals measured in hundreds
so the point (2,8) means
x = 2
y = f(2) = 8
so it means for 2*100=200 animals, the cost is 8*1000=8 000
The correct answer is then
There are 200 animals, and the cost is $8,000 daily
hope this helps
Answer:
k=2
Step-by-step explanation:
7[k+8]=70
First distribute the 7 into the k+8
7k+56=70
Then subtract the 56 on both sides since we want to isolate the variable
7k=14
Lastly divide each side by 7 to get the variable by itself and its value
k=2
We can check this by plugging 2 into the equation. We substitute for 2 in place of k.
7[2+8]=70
First do inside the brackets
7[10]=70
Next multiply
70=70
The equation is true so we know for sure that 2=k
