Answer:
a) 13.277
Step-by-step explanation:
The chi-square critical value can be assessed using chi-square area table and for this table need value of alpha and degree of freedom.
The value of alpha is given which is 0.01 and degree of freedom can be calculated as
df=k-1
Where k represent the categories which are 5 in the given case.
df=5-1=4.
For alpha=0.01 and df=4, we get the chi-square critical value 13.277.
Mercury is larger because 4,878 km vs 1736.5 x 2 = 3473 km. And since radius is half of the diameter we are multiplying by 2. So in short, Mercury is larger. Hope this helps!!!
To find cost per ounce divide the total price by the total ounces.
1.4 / 3.5
$ 0.40 per ounce
We have a property for odd functions, which is given below. Let f(x) be an odd function then it must satisfy the below - mentioned property.

Now, we have been given the function 
For this function to be odd, it must satisfy the above written property.
Replace x with -x, we get

And, we have to also find

Hence, in order to the given function to be an odd function, we must determine whether 9-4(-x)^2 is equivalent to -(9-4x^2) or not.
Therefore, C is the correct option.
