Y is the midpoint of XZ and W is the midpoint of VX. If VZ = s + 14 and WY = s, the value of s is 14.
Define midpoint.The point that divides a line segment into two equal halves is known as the midway in geometry. A point that divides a line segment into two equal halves is the midpoint of the segment. In other words, the line segment's midpoint is precisely in the middle. The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
Given,
VZ = s + 14
WY = s
VZ bisects WY
VZ = 2WY
s + 14 = 2(s)
s + 14 = 2s
2s - s = 14
s = 14
Y is the midpoint of XZ and W is the midpoint of VX. If VZ = s + 14 and WY = s, the value of s is 14.

Three runners competed in a race data were collected at each mile mark for each runner If the runner ran at a constant paste the data would be linear a regression line was fitted to their data Use the residual plots to decide which data set is best fit by regression line and then identify the runner that kept the most consistent pace
Answer:
Runner C
Step-by-step explanation:

The linear regression for the best fit of the data to identify the runner that kept the most consistent pace is Runner C
What is linear regression line?The connection between the independent (x) and dependent (y) variables in the graph can be graphically represented using regression lines.
In a linear model, the terms are added rather than multiplied, divided, or provided as a non-algebraic function, as has been the case thus far in this section. Analysis of experimental, monetary, and biological data as well as complex system prediction are both possible using linear modelling.
A statistical technique used to build a linear model is called linear regression. The model explains how one or more independent variables Xi relate to a dependent variable y (also known as the response) (called the predictors). The distance between each data point and the regression line is called a residual.
Given data ,
Three runners competed in a race data were collected at each mile mark for each runner
And , If the runner ran at a constant paste the data would be linear
Now , a linear a regression line was fitted to their data
And , In linear regression, consistent data refers to a set of data points that fall in a linear pattern with a small amount of scatter around the line of best fit. The data is said to be consistent if the residuals (the vertical distances between the observed data points and the predicted values on the line of best fit) are relatively small and do not exhibit any patterns or trends.
So , the runner C has the most consistent pace among the three runners
Hence , runner C is the best fit for the regression line

i have been trying to solve this compound and double angle question please help me find the answer to these question guys
Answer:
These type of questions are super tricky b/c you have to remember all the different versions of the identities, and then they put the question in some odd form, I feel like this should land math professors in jail , for dishonesty , b/c it's really a form of "how tricky can I make a question and still have a way to solve it" anyway,
Step-by-step explanation:
a)
next the question asks 1-cos 2A and this is total abuse of notation. the way this should be written is 1- cos( 2A) so we know that the A is part of the cosine functions input... btw.. in any computer program, it would never ever let you get away with that top form of the expression. :/ anyway... I keep ranting.. huh... sorry :P
1-cos(2A) is an odd form of the identity 1/2(1-cos(2A) = [tex]sin^{2}[/tex](A) the 1/2 is missing but we can add that pretty easy, we just have to remember to take it out too. I usually forget to do that. and my professor marks me off completely, totally wrong, but I just miss one small thing :/ anyway....
our 1-cos(2A) needs the 1/2 added to it. or if we move that 1/2 to the other side it looks like 2*[tex]sin^{2}[/tex](A) = 1-cos(2A) and this is that "odd" from of the identity that I was talking about.
next let's deal with sin(2A) it has an identity of 2 sin(A)cos(A) which is really nice for us b/c it will cancel out the 2 in then numerator for us, nice !
now our fraction looks like [2* [tex]sin^{2}[/tex](A)] / 2 sin(A)cos(A)
so cancel out one of the sines
2*sin(A) / 2 cos(A)
cancel the 2s
Sin(A) / Cos(A) = Tan(A)
nice it worked out :P
b)
by the above that we just worked out, then
Tan(15) = Sin(15) / Cos(15)
I had to look up what sin of 15 is b/c it's not one of those special angles but it does have an exact form of
Sin(15) = (√3 - 1) / 2√2
Cos(A) = (√3 + 1) / 2√2
you can use rule of Cos(A-B) = Cos(A)Cos(B)+Sin(A)Sin(B) to get the above and a similar rule for Sin(A-B)
back to our problem, the 2√2 will cancel out
then we have
Tan(15) = (√3 - 1) /(√3 + 1)
in the form that is above that's exact, the roots could be approximated but i'll just leave that in the form that is exact. Most math professors like that form.

Consider the following statement. ∀ integer d, if 6 d is an integer then d = 3. Which of the following is a negation for the statement? ∃ an integer d such that 6 d is an integer and d ≠ 3. ∃ an integer d such that 6 d is not an integer and d = 3. ∀ integer d, if 6 d is not an integer, then d ≠ 3. ∀ integer d, if d ≠ 3, then 6 d is not an integer. ∀ integer d, if d = 3, then 6 d is an integer.
Answer:
The correct option is the first:
∃ an integer d such that 6d is an integer and d ≠ 3
Step-by-step explanation:
If 6d is an integer, then d = 3
Let's divide the statement into two:
Let "If 6d is an integer" be p and "then d = 3" be q.
The statement is a conditional statement. Therefore, we have
p ⇒ q
The negation of p ⇒q, ¬(p ⇒ q) ≡ p ∧ ¬q
I have attached an image proving the above.
Using this: ¬(p ⇒ q) ≡ p ∧ ¬q
Then, we leave p as it is and negate q.
P is "if 6d is an integer"
q is "then d = 3," hence ¬q is "then d ≠ 3."
Therefore, the negation of "If 6d is an integer, then d = 3" is "If 6d is an integer, then d ≠ 3."
The correct option is the first:
∃ an integer d such that 6d is an integer and d ≠ 3

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
The base of the triangle = 12
The perpendicular distance of the triangle = 7
Now, We know that;
Pythagoras theorem stated as;
⇒ Hypotenuse² = Base² + Perpendicular²
⇒ x² = 12² + 7²
⇒ x² = 144 + 49
⇒ x² = 193
⇒ x = √193
⇒ x = 13.90
Thus, The missing side of this right triangle is, 13.90 units.

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