Answer:
CI= [28.67,45.33]
Step-by-step explanation:
-Given the mean is $37 and the standard deviation is $17
#A 95% confidence interval can be calculated as follows:
Hence, the 95% confidence interval is [28.67,45.33]

Answer:
The package where they charge the same must cost $2
Step-by-step explanation:
Given
UPS
FedEx
Required
What pound do both charges are the same
Represent the charges with x;
For UPS, it can be written as:
For FedEx:
It is:
Equate these charges together
Collect Like Terms
<em>Hence, the package where they charge the same must cost $2</em>
The maximum number of of bouquets the gardener could have made is 3
<h3>How to find unknown parameter</h3>
Total = 45
let
- number of daffodils = x
- number of tulips = y
Roses = 4x
Tulips = 4x + 15
Total = roses + daffodils + tulips
45 = 4x + x + (4x + 15)
45 = 5x + 4x + 15
45 = 9x + 15
45 - 15 = 9x
30 = 9x
x = 30/9
x = 3.33333333333333
Approximately,
x = 3

Answer:
1. Translation 3 units to the right;
2. Reflection across the x-axis;
3. Translation 4 units up.
Step-by-step explanation:
First, rewrite the function in following way:
Apply such transformations:
1. Translate the graph of the parent function 3 units to the right to get the graph of the function
2. Reflect the graph of the function across the x-axis to get the graph of the function
3. Translate the graph of the function 4 units up to get the graph of the function
