Answer: B) There is not convincing evidence because the interval contains 0.

==============================================================

Explanation:

The 98% confidence interval (-0.36, 0.22) means we are 98% confident that the difference of proportions p1-p2 is somewhere between those two endpoints of -0.36 and 0.22 Values in this interval are possible values of p1-p2.

Note how 0 is in this interval. So it's possible that p1 - p2 = 0. Because of this, we fail to reject the null hypothesis. The null in this case is that p1 - p2 = 0 which can be restated as p1 = p2. The null is the assumption that the two population proportions (p1 and p2) are the same.

The alternative hypothesis is that p1-p2 is not zero. If we got a confidence interval like (0.22, 0.55), this example doesn't have 0 in the interval, then that would mean we reject the null since its unlikely that p1-p2 is equal to zero.

----------------

In short,

In this case, we fail to reject the null and we don't have enough evidence to show that p1 = p2 is false. So for now, we assume it's true.

Answer: y= x-2

Step-by-step explanation:

Perpendicularity entails the slope of line a is -1 divided by the slope of line b

m1= (-1/m2)

From y=Mx +c

We compare with x-4y=7

y=(1/4)x-7/4

Meaning m2= 1/4

m1= -1/(1/4)= -1*4= -4

((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1

x1= 2, y1= -4

((y-(-4))/(x-2))= -4

((y+4)/(x-2))= -4

Cross multiply

y+4= -4(x-2)

y= x-2

Answer:

The answer is 15

Step-by-step explanation:

[tex]3 \times 5 = 15[/tex]

a. y= 5

b. x=2

c. x= -?

I'm stuck on the last one but I'll tell you how to do it.

For a. I looked at line one and you see that it's on 5? well that is written as y= 5 because there is not x coordinate.

Answer:

[tex]L(x) = 360 - 15 w[/tex]

Step-by-step explanation:

See comment for complete question

Given

[tex]Amount = \$360[/tex]

[tex]Rate = \$15[/tex] weekly

Required

Determine the function to represent the scenario

The amount (L) owed in w weeks is represented as:

[tex]Amount\ Owed = Amount - Rate * Weeks[/tex]

We used negative because the amount reduces weekly.

So, we have:

[tex]L(w) = 360 - 15 * w[/tex]

[tex]L(x) = 360 - 15 w[/tex]

Answer:

X= 5.44  y= 17.85

Step-by-step explanation:

Given that your B angle is 60 degress you can use 17tan(60) to get X which is 5.44.

Then you a²+b²=c² to find y.

y=√17²+5.44²

y= 17.85

Answer: X= 5.44  y= 17.85

Option D is correct,  2x=5 is the equation which matches the hanger diagram.

Two or more expressions with an Equal sign is called as Equation.

We need to find the equation which matches the hanger diagram.

Hanger models are a visual representation of an equation

For the hanger to remain balanced, each side has to have the same weight. Like a seesaw, a scale, or a barbell.

In the left side of hanger there 2 x's and on right side there are fives ones.

So 2x=5 is the equation which satisfies the given hanger diagram.

Hence, Option D is correct,  2x=5 is the equation which matches the hanger diagram.

Answer:

Step-by-step explanation:

Eva has borrowed 150 songs from her friend. She plans to download an equal number of songs on her music player each week for 5 weeks. The graph shows the number of songs left to download, y, for a certain number of weeks, x:

A graph titled Song Downloading shows Number of Weeks on x-axis and Number of Songs Left to Download on y-axis. The x-axis scale is shown from 0 to 5 at increments of 1, and the y-axis scale is shown from 0 to 280 at increments of 40. A straight line joins the ordered pairs 0, 200 and 1, 160 and 2, 120 and 3, 80 and 4, 40 and 5, 0.

Part A: What is the rate of change and initial value of the function represented by the graph, and what do they represent in this scenario? Show your work to find the rate of change and initial value. (6 points)

Part B: Write an equation in slope-intercept form to model the relationship between x and y. (4 points)

Adjacent angles must sum to 180 degrees.

x+32=180

x=148 degrees

Answer:

x= 148

Step-by-step explanation:

line CD is a straight angle which means it is 180 degree

to find x you must subtract the known angle from the straight angle

your equation should look like this

180-32=148

Answer:

it is not a function

Step-by-step explanation:

if you can pass a vertical line through more than one point it is not a function, you have two points with the same x and different y

(-13,4) and (-13,9)

because you have two different y values for the same x it would fail the vertical line test and thus is not a function
