Well, first you should make both sides of the equation to the power of 2.
So, you'll have 7X = 1225, and then X is 175 :)
Have a wonderful day!
A. write the question that represents the food supply then write the equation that represents the park attendance
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of independent variables is 
The number of observation is 
Since n is are independent variables then their degree of freedom is 3
The denominator(i.e z) degrees of freedom is evaluated as



So for the numerator (n) the degree of freedom is Df(n) = 3
So for the denominator(i.e z) the degree of freedom is Df(z) = 43
