your answer is
-6x-5x^2+24/4
and can also be written as
-(5x^2+6x-24) as shown in the attachment with the steps
Answer:
μy = $6.56 ; σy = 2.77
Step-by-step explanation:
Given the data :
Mean μx= $8.56
Standard Deviation σx ≈ 2.77
Profit, Y on pizza with current promo :
Price off on pizza = $2
Y = x - 2
μx = E(x) = $8.56
μy = μ(x - 2)
μy = μx - $2
μy = $8.56 - $2
μy = $6.56
For the standard deviation of y
σx ≈ 2.77
σy = σ(x - 2)
σy = σx - 2
Constants are treated as 0 for standard deviation
σy = 2.77
Answer:
A. 28
B. 1 min
C. 2 mins
Step-by-step explanation:
The first question is clearly incomplete. The model is not presented so we cannot estimate the volume of the flask but if it was given, the volume is equal to the volume of the cylinder plus the sphere. The cylinder volume is V = pi(r^2)h.
To find the volume of the sphere we use the given equation <span>4/3πr^3. The radius is 4.5/2. The volume is 47.71 cubic inches. </span>
