Since the time series has trend and seasonal pattern, to forecast the quarterly sales of the textbook, the following regression equation was found: stack y t with overparenthesis on top equals 2120 space minus 620 space Q t r 1 space minus space 1320 space Q t r 2 space plus space 290 space Q t r 3 space plus space 24 space t , where Q t r 1 , Q t r 2and Q t r 3 are dummy variables corresponding to Quarters 1, 2 and 3, and t = time period.

Answers

Answer 1

Answer:

Y(2)= 2120+ 48= 2168

Step-by-step explanation:

The given equation is

Yt= 2120 - 620 Qtr 1 t -1320 Qtr 2 t + 290 Q tr3 t + 24 t

Taking the quarter 1 , 2 and 3 to be dummy variable the predicted sales for the 4th qtr are

Yt= 2120 - 620 Qtr 1(0) -1320 Qtr 2(0) + 290 Q tr3 (0)  + 24 (1)

Y(1)= 2120 + 24 = 2144   ( for year =1)

Y(2)= 2120+ 48= 2168    ( for year =2)

Y(3)= 2120 + 72= 2192   ( for year =3)

where t is the number of years.

So for the next year the fourth quarter sales are predicted to be 2168.

4. SAS(or Side-Angle-Side)

Step-by-step explanation:

1 is given because that is whats given to you.

2 is Similar Lines because, on the diagram, when a line has a small dash on it and another line has the same dash, this means that they are similar.

3 is Vertical Angle because a vertical angle is an angle that is reflective of another angle and, according to the Vertical Angle Theory, all vertical angles are equal.

4 is SAS because you always go counterclockwise on the triangle when finding the congruent abbreviation and her you can see it is Side(LN=NW), Angle(LNS=WNK), Side(SN=NK).

Annabelle lives at Bermondsey in London. She has to speak at a conference inBirmingham at 10.30am.

It will take her an hour from her home to get to Euston Rail
Station, from where she will get a train to Birmingham.

The train journey from Euston
to Bimingham is an hour and 10 minutes.

Trains to Birmingham run at the following times: 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.

The meeting venue in Birmingham is a 5-minute walk from the station.

What is the latest time that Annabelle can leave home, if she is to make it on time for
the meeting in Birmingham

Please HELP!!! DUE TODAY!!
Thank you so much.

Answers

Answer:

7:45

Step-by-step explanation:

work backwards from 10:30!

u need 5 min to walk from meeting place to station, therefore u need to done riding the train by 10:25.

then u know that the train is an hour and 30 min, therefore u have to ride the train before or at 8:55 (10:25 minus an hour and a half)

the latest time for the train to leave is 45 min past the hour. therefore you will ride the 8:45 train.

since we already know that we are riding the 8:45 train by latest, you have to leave an hour early to get to the station. so you need to leave home by 7:45.

hope i was helpful !

The latest time that Annabelle can leave home is the she leaves home and she won't be late for her meeting

Time of meeting = 10.30am

Time she will spend before getting to meeting:

home to get to Euston Rail Station = 1 hour

train journey from Euston to Bimingham = 1 hour 10 minutes

Trains to Birmingham = 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.

The latest time is 45 minutes

Walk from the meeting venue in Birmingham from the station = 5 minute walk

Total time = 1 hour + 1 hour 10 minutes + 45 minutes + 5 minutes

= 3 hours

Counting 3 hours backward from 10:30 am = 7:30 am

Therefore, the latest time Annabelle can leave home is 7:30 am

Explain what the vertical line test is and how it is used.

Answers

Answer:

Sample Response: The vertical line test is a way to determine if a relation is a function. This test determines if one input has exactly one output on the graph. If any vertical line passes through more than one point on the graph, then the relation is not a function because two different outputs have the same input.

Step-by-step explanation:

I just got the sample response.

The vertical line test is a method used to determine whether a graph represents a function or not.

The vertical line test is a method used to determine whether a graph represents a function or not. It is a visual tool that helps identify if there is a unique output for every input value in a given graph.

To perform the vertical line test, imagine a vertical line that can be moved across the graph. If the vertical line intersects the graph at only one point for every possible position, then the graph represents a function.

In other words, if no vertical line passes through the graph in more than one location, the graph passes the vertical line test and is considered a function.

The vertical line test is a simple and effective way to check if a graph represents a function visually. It helps determine the relationship between the input and output values and identifies whether there is a one-to-one correspondence or not.

35 <7(2−b) or 13(15b−12)≥21

Answers

35 < 7 ( 2-b ) or 13 ( 15b-12)>= 21

35 < 14 - 7b or 195 b - 156 >= 2

35-14<-7b or 195b >= 2 + 156

21 < -7b or 195 b >= 158

b < 21/-7 or b>= 158/195

b < -3 or b >= 158/195

The simplification form of the inequality 35 <7(2−b) or 13(15b−12)≥21 is b < -3 or b  ≥  158/195.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

The inequality is:

35 < 7(2 − b) or 13(15b − 12) ≥ 21

After simplification:

35 < 14 - 7b or 195 b - 156 ≥  2 (using distributive property)

35-14<-7b or 195b ≥  2 + 156

21 < -7b or 195 b ≥  158

b < 21/-7 or b ≥  158/195 (division property of equality)

b < -3 or b  ≥  158/195

Thus, the simplification form of the inequality 35 <7(2−b) or 13(15b−12)≥21 is b < -3 or b  ≥  158/195.

Answer:

AC = 30 in

m∠B = 36,9°

m∠A = 53,1°

Step-by-step explanation:

1 AC

You gan get AC with the pythagorean theorem:

a²+b²=c²

We are looking for side b of the triangle, so the equation is rearranged for b.

BC²+AC²=AB²    | -BC²

AC²=AB²-BC²

AC=√(AB²-BC²)

Now the given values are used:

b=√(50²-40²)

b=√(2500-1600)

b=√900

b=30 in

2 m∠B

This angle can be calculated using the sine law:

sine(angle)=opposite cathete/hypothenus

We are looking for angle m∠B of the triangle.

sin(m∠B)=AC/AB

sin(m∠B)=30in/50in

sin(m∠B)=0,6

m∠B=36,9°

3 m∠A

This angle can be calculated using the sine law:

sine(angle)=opposite cathete/hypothenus

We are looking for angle m∠A of the triangle.

sin(m∠A)=BC/AB

sin(m∠A)=40in/50in

sin(m∠A)=0,8

m∠A=53,1°

Step-by-step explanation:

Answer:

Divide both sides by a constant to simplify the equation.  Thus the second option.

Step-by-step explanation:

Solve for x:

9 - 10 x = -1

Hint: | Isolate terms with x to the left hand side.

Subtract 9 from both sides:

(9 - 9) - 10 x = -9 - 1

Hint: | Look for the difference of two identical terms.

9 - 9 = 0:

-10 x = -9 - 1

Hint: | Evaluate -9 - 1.

-9 - 1 = -10:

-10 x = -10

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -10 x = -10 by -10:

(-10 x)/(-10) = (-10)/(-10)

Hint: | Any nonzero number divided by itself is one.

(-10)/(-10) = 1:

x = (-10)/(-10)

Hint: | Any nonzero number divided by itself is one.

(-10)/(-10) = 1:
