An agronomist is an expert in soil management and crop production. A certain state hires an agronomist to investigate whether th

ere is a linear relationship between a wheat stalk’s height and the yield of wheat. The agronomist collected data and used the data to test the claim that there is a linear relationship at a significance level of α = 0.05. The agronomist tested the following hypotheses.
H0 : β1 = 0
Ha : β1 ≠ 0
The test yielded a p -value of 0.25. Which of the following is a correct conclusion about the claim?
A. The null hypothesis is rejected because 0.25 > 0.05. There is sufficient evidence to suggest that there is a linear relationship between a wheat stalk's height and its yield.
B The null hypothesis is not rejected because 0.25 > 0.05. There is sufficient evidence to suggest that there is a linear relationship between a wheat stalk's height and its yield.
С The null hypothesis is rejected because 0.25 > 0.05. There is not sufficient evidence to suggest that there is a linear relationship between a wheat stalk's height and its yield.
D The null hypothesis is not rejected because 0.25 > 0.05. There is not sufficient evidence to suggest that there is a linear relationship between a wheat stalk's height and its yield.
E The null hypothesis is accepted because 0.25 > 0.05. There is sufficient evidence to suggest that there is not a linear relationship between a wheat stalk's height and its yield.

Answer:

D The null hypothesis is not rejected because 0.25 > 0.05. There is not sufficient evidence to suggest that there is a linear relationship between a wheat stalk's height and its yield.

Step-by-step explanation:

Given the hypothesis :

H0 : β1 = 0

Ha : β1 ≠ 0

The Pvalue = 0.25 ; α = 0.05

Decision region :

Reject H0 ; if Pvalue < α

Comparing the Pvalue and α - value

0.25 > 0.05

Here, the Pvalue is > α ; hence, we fail to reject the Null, H0

Hence, there is no significant evidence to suggest that there is a linear relationship between what's stalk height and its yield.

Consider the incomplete paragraph proof.
Leya [2.2K]

The hypotenuse is c = a\sqrt{2}  times the length of each leg 'a'. Triangle XYZ is a isosceles right triangle, therefore the Pythagoras theorem becomes  and this can be evaluated by using properties of isosceles triangle.

According to the statement

we have given that a theorem and we have to prove it.

So, For this purpose,

The given information is :

Isosceles triangle XYZ where Angle X = 45^{0} Angle Y = 45^{0} Angle Z = 90^{0}

Let the sides of triangle XYZ be a, b, and c. Then side XY = c, YZ = b and ZX = a.

Now, it is given that triangle XYZ is isosceles triangle therefore, the shorter sides must be equal that is, a = b.

Now use Pythagoras theorem

a^{2} + b^{2} = c^{2}

But here a= b then the equation become

a^{2} + a^{2} = c^{2}

Then after solving it become

2a^{2} = c^{2}

And here we have to find the value of the hypotenuse,

so we solve it for c.

Then

c = a\sqrt{2}

From this it is clear that the

it can be concluded that the hypotenuse is  times the length of each leg 'a'.

A positive integer is 11 more than 18 times another. Their product is 6030. Find the two integers.
allsm [11]

Answer:

18 and 335

Step-by-step explanation:

y = 18x + 11

x * y = 6030

x * (18x + 11) = 6030

18x^2 + 11x = 6030

18x^2 + 11x - 6030 = 0

(18x + 335)(x - 18) = 0

18x + 335 = 0                 x - 18 = 0

18x = -335                      x = 18

x = -335/18

x is gonna have to be a positive number...so x = 18

y = 18x + 11

y = 18(18) + 11

y = 324 + 11

y = 335

so ur numbers are 18 and 335

1. How do you prove congruence through transformations?
konstantin123 [22]

One can prove congruence through transformation if they have the same shape and size.

The congruency postulates include:

  • SSS - Side-Side-Side
  • SAS - Side-Angle-Side
  • ASA- Angle-Side-Angle
  • AAS - Angle-Angle-Side
  • RHS - Right angle-Hypotenuse-Side

<h3>What is congruence?</h3>

In geometry, it should be noted that two figures are congruent if they have the same shape and size.

In this case, if two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.

One can prove triangle congruence using congruency postulates by using the SSS theorem( side side side theorem).

It should be noted that the congruence postulate is used to illustrate that the triangles are equal.

N-31/4 =2 simple equation
Zanzabum

Answer:

n = 5.75

Step-by-step explanation:

original equation

n - 31/4 = 2

multiply everything by 4

n * 4 - 31/4 * 4 = 2 * 4

simplify

4n - 31 = 8

add 31 to both sides

4n - 31 + 31 = 8 + -31

simplify

4n = -23

divide both sides by 4

4n/4 = -23/4

simplify

n = 5.75
