Vladimir [108]

Answer:

53.13°

Step-by-step explanation:

Using Sine rule

b / Sin B = a / Sin A

5/ Sin90 = 4 /Sin A

5/1 = 4 /SinA

Sin A = 4/5

A = arc sin(0.8)

A = 53.13010

A = 53.13 °

A pizza shop sells three sizes of pizza, and they track how often each size gets ordered along with how much they profit from ea
kari74 [83]

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
