Answer:
0.0421
Step-by-step explanation:
Mean(μ) = 12.00 oz
Standard deviation (σ) = 0.11 oz
Z = (x - μ)/σ
Z = (12.19 - 12.00) / 0.11
Z= 0.19/0.11
Z = 1.727
From the normal distribution table, Z = 1.727 = 0.4579
Φ(Z) = 0.4579
Recall that if Z is positive
Pr(x>a) = 0.5 - Φ(Z)
Pr(x > 12.19) = 0.5 - 0.4579
= 0.0421
The length of the flagpole is x - 5 yards
<h3>How to determine the length of the flagpole?</h3>
The area of the flagpole is given as:
Area = x^2 - 10x + 25
Expand the expression
Area = x^2 - 5x -5x + 25
Factorize the expression
Area = (x - 5)(x - 5)
Express as squares
Area =(x - 5)^2
The area of a square is
Area = Length^2
So, we have:
Length = x - 5
Hence, the length of the flagpole is x - 5 yards

Answer:
Min 42 dinners
Step-by-step explanation:
The ratio is the following:
C : 7
B : 5
F : 2
That means that every 2 fish dinners, they served 5 beefs and 7 chickens.
If they served more than 5 fish dinners, that means at least 6 fish dinners.
And by proportion,
X= (6*5)/2= 15 BEEF
X= (15*7)/5= 21 CHICKEN
ADDING: 21+15+6= 42
<em>So the minimum amount of dinners served was 42.</em>
