Answer: 9" by 7"
Step-by-step explanation:
let the dimensions of the rectangle be x and y
equation 1: xy=63
equation 2: 2(x+y)=32
first, rearrange the terms
(1′): y=63/x
(2′): y=16−x
(1′)-(2′): 0=63/x−16+x
multiply the equation by x
0=x2−16x+63
0=(x−9)(x−7)
so x = 7 or x = 9
from this, y = 9 when x = 7 and y = 7 when x = 9
so, the dimension of the rectangle is 9″ by 7″
The maximum number of shrubs (x) = a(area) divided by 15.9
a(area)=37.1*15
37.1*15= 556.5
556.5/15.9=x
556.5/15.9=35
35=x
The first one is the first one
The second one is the fourth one
The third one is the third one
The fourth one is the second one
The fifth one is the third one
The sixth one is the second one
The correct statement that can be made about the means is a. There is not enough evidence to suggest that the means are different.
<h3>What is true about the means?</h3><h3 />
Given that α = 0.01, we can use an ANOVA analysis to determine the p-value of the means.
When we run the means through an ANOVA software, the p-value can be found to be 0.1142.
This figure is greater than α = 0.01.
This means that we do not have the evidence to reject the null hypothesis that the means are different.
