Answer:
The overview of the given situation is described in the explanation segment below.
Step-by-step explanation:
- By the details received, the reference variable becomes actual prevalence or occurrence of another virus whereas the descriptive variable becomes precipitation 'Precipitation compensated for 79% throughout variability with prevalence.'
As we know that the determination's coefficient will be:
⇒ 
(Percent of variance in the answer variable described by the explanatory variable).
Now the correlation among the two variables will be:
As we know,
⇒ 
⇒ 
⇒ 
⇒ 
The answer is in the picture
Important: indicate exponentiation with " ^ "
Thus, x = ( y - 4 )2 + 27 becomes <span>x = ( y - 4 )^2 + 27
This can be re-written as x = y^2 - 8y + 16 + 27, or x = ay^2 - 8y + 43. This is the equation of the parabola in standard form x = ay^2 + by + c.</span>
Add 5/7 on both sides.
It'll cancel out the negative 5/7, and it will make the x variable only equal to one number (Well, a mixed number.)
Answer: y = 1.50x + 19 and y = 2.75x + 14
y = 25
x = 4
Both services will charge an equal cost of $25 for 4 hours.
