Answer:
- Given below.
Step-by-step explanation:
Gift bag is shaped in a rectangular prism.
<em> rectangular volume: length * width * height</em>
( 2w + 4 ) ( w ) ( 18 - w ) = 1152
( 2w² + 4w ) ( 18 - w ) = 1152
-2w³+32w² +72w = 1152
-2w³+32w² +72w - 1152 = 0
w = 16 , -6 , 6
w = 16 , 6
- length = ( 2w + 4 ) = 36 inch , 16 inch
- width = ( w ) = 16 inch , 6 inch
- height = ( 18 - w ) = 2 inch , 12 inch

Answer:
critical value = 5.29
Step-by-step explanation:
Given that they are divided into 4 groups and a sample of 5 test was selected
N = 5 * 4 = 20
k = 4
∝ = 0.01
Df for numerator ( SS group )= k - 1 = 3
Df for denominator ( SSE group ) = N - k = 20 - 4 = 16
DF ( degree of freedom )
Next we will use the F table to determine the critical value
Critical value = = 5.29
Answer:
5.5%
Step-by-step explanation:
To solve this problem we can use a modified version of the simple interest formula which is shown below:
<em>I = interest amount</em>
<em>P = principal amount</em>
<em>t = time (years)</em>
<em />
The first step is to find the interest gained from the investment.
Next, plug in the values into the equation:
Multiply the bottom values
Divide the values
The last step is to convert 0.055 into a percent:
The interest rate is 5.5%
