Answer:
Length of the mural should be 20.78 m
Step-by-step explanation:
Let the length of the mural be L and the width W
Area = L × W = 60 m²
Ticket wants the L = 15 + 2W
Substitute for L in the Area eqn
(15 + 2W) × W = 60
15W + 2W² = 60
2W² + 15W - 60 = 0
Solving the quadratic equation
W = 2.89 m or - 10.39 m
Obviously, the width cannot be negative,
So, W = 2.89 m
L = 15 + 2W = 15 + 2(2.89) = 20.78 m
Check - L × W = 20.78 × 2.89 = 60 m²
Hope this Helps!!!

Answer:
The confidence interval for the true mean calorie content is

Step-by-step explanation:
In this problem we know the mean and standard deviation fo the sample, so we can compute the CI like this:

We need to determine t for 10-1=9 degrees of freedom and 99% confidence level. We look up in the t-table and the value for t is 3.2498.
Then we can calculate the limits of the CI:

Mult. $7.25 by 4 times 4 (4 PIZZAS per week, for 4 weeks):
$7.25(4)(4) = $116
Fine dining: 2($85) = $170
So, the fine dining costs more!
Multiplicity is how many times each root repeats
(x-r1) where r1 is the root
root is 1 of multiplicity 2 means
(x-1)^2
root -2 multiplicity 3 means
(x+2)^3
so the function is
(x-1)^2(x+2)^3
f(x)=(x-1)^2(x+2)^3
expanded
f(x)=

(x-1)^2(x+2)^3
