Tumbleweed, commonly found in the western united states, is the dried structure of certain plants that are blown by the wind, kochia, a type of plant that turns into tumbleweed at the end of the summer is a problem for farmers because it takes nutrients away from soil that would otherwise go to more beneficial plants. scientists are concerned that ko:hia plants are becoming resistant to the most commonly used herbicide, glyphosate. in 2014, 19.7 percent of 61 randomly selected kochia plants were resistant to glyphosate. in 2017, 38.5 percent of 52 randomly selecteikochia plants were resistant to glyphosate. do the data provide convincing statistical evidence, at the leve of 0.05, that there has been an increase in the proportion of all kochia plants that are resistant to glyphosale?
Since we are dealing with a proportion, it is determined by using the z-distribution that there is insufficient evidence to draw the conclusion that the proportion of all kochia plants that are resistant to glyphosate has increased because the test statistic is less than the critical value for the right-tailed test.
In this problem, we consider that:
[tex]p_{1}[/tex] is the proportion in 2014.[tex]p_{2}[/tex] is the proportion is 2017.What are the hypothesis tested?At the null hypothesis, we test if there has been no increase, that is, the subtraction is of 0.[tex]$H_{0}: p_{2}-p_{1}=0$[/tex]
At the alternative hypothesis, we test if there has been an increase, hence:[tex]$H_{1}: p_{2}-p_{1} \neq 0$[/tex]
What is the distribution of the difference of sample proportions?The proportions and standard errors are given by:
[tex]p_{1}=0.197, s_{1}=\sqrt{\frac{0.197(0.803)}{61}}=0.0509\\p_{2}=0.385, s_{2}=\sqrt{\frac{0.385(0.615)}{52}}=0.0675[/tex]
Hence, the distribution has mean and standard error given by:
[tex]\bar{p}=p_{2}-p_{1}=0.0675-0.0509=0.0166\\s=\sqrt{s_{1}^{2}+s_{2}^{2}}=\sqrt{0.0509^{2}+0.0675^{2}}=0.0845[/tex]
What is the test statistic?It is given by:
[tex]$z=\frac{\bar{p}-p}{s}$[/tex]
In which p = 0 is the value tested at the null hypothesis, hence:
[tex]z=\frac{0.0166}{0.0845}\\$z=0.2$[/tex]
What is the decision?Considering a right-tailed test, as we are testing if the proportion is greater than a value, with a significance level of 0.05, the critical value is of [tex]$z^{*}=1.645$[/tex]There is insufficient information to establish that the fraction of all kochia plants that are resistant to glyphosate has increased because the test statistic is smaller than the crucial value for the right-tailed test.Learn More about the z-distribution here: brainly.com/question/26454209

Step-by-step explanation:
x -2(x+1) + 3(x-2) + 2(x-6) = 0
here, we need to distribute the numbers on the outside of the parentheses to the inside numbers.
As you may know, when two numbers are in parentheses, they are to be multiplied--and it is the same idea here.
When we have a number, say 3, multiplied by parentheses, say (x - 2), we multiply all inside numbers by the outside number, which is called distributing.
We know that 3(x) = 3x, and that 3(-2) = -6, so we distribute
3(x - 2) to be 3x - 6
let's do that for all of our parentheses:
x -2(x+1) + 3(x-2) + 2(x-6) = 0
-2( x + 1 )
-2x - 2
3(x - 2)
3x - 6
2( x - 6)
2x - 12
Now, let's rewrite our problem:
x -2(x+1) + 3(x-2) + 2(x-6) = 0
x - 2x - 2 + 3x -6 + 2x - 12 = 0
First, we should combine like terms:
x - 2x + 3x + 2x - 2 - 6 - 12 = 0
(x - 2x = -x; -x + 3x = 2x; 2x + 2x = 4x)
( - 2 - 6 = -8; -8 - 12 = -20
So, we are left with:
4x - 20 = 0
At this point, we want to get x alone (so that we can find what "x" is)
4x - 20 = 0
+ 20 + 20 ( add 20 to both sides of the equation to isolate x )
4x = 20
÷ 4 ÷ 4 (divide both sides by 4 to find "1"x)
x = 5
So, we know that the value of x is 5, or x = 5

Applying the linear pair theorem and the sum of interior angles of hexagon, we have:
Angle 7 = 92°
Angle 1 = 107°
What is the Linear Pair Theorem?According to the linear pair theorem/postulate, when two angles lie on a straight line, the sum of their measures equals 180 degrees.
Angle 7 lie on a straight line with 88°, therefore, applying the linear pair theorem, we have:
Angle 7 + 88 = 180
Subtract both sides by 88
Angle 7 + 88 - 88 = 180 - 88
Angle 7 = 92°
Also, using the linear pair theorem, we have:
Angle 5 = 180 - 64
Angle 5 = 116°
Angle 3 = 180 - 57
Angle 3 = 123°
Sum of interior angles of hexagon equals 720°, therefore:
Angle 1 + angle 3 + angle 5 + angle 7 + 118 + 164 = 720°
Plug in the known values
Angle 1 + 123 + 116 + 92 + 118 + 164 = 720
Angle 1 + 613 = 720
Subtract both sides by 613
Angle 1 + 613 - 613 = 720 - 613
Angle 1 = 107°

[tex]\implies C(-459.67)=\dffrac{5}{9}(-459.67-32)=-273.15[/tex]
This means the range of the function C(F) is C(F) ≥ -273.15
The domain of the inverse function is the range of the function.
Therefore, the domain of the inverse function in interval notation is: [-273.15, ∞)
Answer: -273.15

Use the image below to describe at least three different ratios, written in simplest form. Include at least one part-to-part ratio and one part-to-whole ratio.
8 out of 36 squares unfilled*
HELP ASAP!!!!!!!!!!!!
The different ratios are 2 : 7, 2 : 9 and 7 : 9
How to determine the ratio?The statement is given as:
8 out of 36 squares unfilled
This means that:
There are 36 squares8 are unfilled28 are filledThe part-to-part ratio is represented as:
Ratio = Unfilled : Filled
This gives
Unfilled : Filled = 8 : 28
Simplify
Unfilled : Filled = 2 : 7
The part-to-whole ratios are represented as:
Ratio = Unfilled : Total
Ratio = Filled : Total
So, we have:
Unfilled : Total = 8 : 36
Filled : Total = 28 : 36
Simplify
Unfilled : Total = 2 : 9
Filled : Total = 7 : 9
Hence, the different ratios are 2 : 7, 2 : 9 and 7 : 9

How to determine the characteristics of rigid transformations by comparing two functions
In this problem we have two functions related to each other because of the existence of rigid transformations. Rigid transformations are transformations applied to geometric loci such that Euclidean distance is conserved at every point of the geometric locus.
Let be f(x) = - 2 · cos (x - 1) + 3, then we use the concept of horizontal translation 4 units in the + x direction:
f'(x) = - 2 · cos (x - 1 + 4) + 3
f'(x) = - 2 · cos (x + 3) + 3 (1)
Now we apply a reflection over the x-axis:
g(x) = - [- 2 · cos (x + 3) + 3]
g(x) = 2 · cos (x + 3) - 3
Therefore, the function g(x) is created by applying an horizontal translation 4 units left and a reflection over the x-axis. (Correct choices: Third option, fifth option)
