Answer:
$0.77
Step-by-step explanation:
To find how much each bottle of juice costs, divide 2.31 by 3:
2.31/3
= 0.77
So, each bottle of juice is $0.77
Let x be the required waranty period, then
P(X < x) = P(z < (x - 12)/(8/12)) = 1 - 0.067 = 0.933
P(z < 12(x - 12)/8) = P(z < 1.498)
12(x - 12)/8 = 1.498
x - 12 = 8(1.498) / 12 = 0.9987
x = 12 - 0.9987 = 11
Therefore, they should waranty for 11 years so that no more than 6.7% fail within that time.
cost of production = %13
Let the price be p, then
revenue less price of failed iron = p - 0.067(13) = p - 0.871
Profit = p - 0.871 - 13 = 5
p - 13.871 = 5
p = 5 + 13.871 = 18.871
Therefore, the should charge $18.87 per waffle iron.
Answer:
Mean = 7
Median = 7.65
Mode = 4.4
Range = 9.9
Step-by-step explanation:
The question is incomplete as it doesn't state what to find. Lets complete the question first. The complete question states that:
Calculate the following for the data set
Mean
Median
Mode
Range
<h3>A) Mean</h3>
Mean = sum of values/ total number of values
Mean = 84/12
Mean = 7
<h3>B) Median</h3>
Arrange the data in ascending order
1.8, 2.5, 2.6, 4.4, 4.4, 7.3, 8.0, 9.5, 10.3, 10.4, 11.1, 11.7
Median = Average of middle values
Median = (7.3+8.0) / 2
Median = 7.65
<h3>C) Mode</h3>
Mode = number which appears most = 4.4
<h3>D) Range</h3>
Range = Max value - Min value
Range = 11.7 - 1.8
Range = 9.9
<span>F for Frank, A or Alice.
F(initial)=1.95 inches
A(initial)=1.50 inches
Frank's equation at .25 inches per year and t representing year variable.
F=1.95+.25t
Alice's equation at .40 inches per year and t representing year variable.
A=1.5+.40t
To figure out how old they will be when their beaks are the same lengths set the equations equal to eachother as the equations are length.
1.95+.25t=1.5+.40t
.45=.15t
t=3 years</span>
