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. The sales in Quarter 4 of the next year are predicted to be

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.

how do you solve this equation 19−4c=17

Answers

Answer:  Whatever you do to one side, you do the same operation on the other. The goal is to get the variable alone with a number on the other side.

Here's how:

Step-by-step explanation:

19−4c=17

19 - 19 - 4c = 17 - 19  Subtract 19 from both sides  19-19 =0 Cancels on the left

-4c = 17-19   subtract: 17-19 = -2

-4c = -2

-4c/4 = -2/-4    Divide both sides by -4  

Negatives divided by Negatives have a Positive quotient  -4/-4 =1, Cancels

John bought a car for $36,000, he didn't have enough money to buy the car totally, so he gave $1000 monthly, how much money did he give after 1 year, and how much does he has to give more?

Answers

There are twelve months in a year, and he pays $1000 a month, so we get [tex]\$1000*12 = $12,000[/tex] spent in a year. He originally needed to spend $36,000, so he has [tex]\$36,000-\$12,000 = \$24,000[/tex] left.

Please mark as Brainliest if you found this helpful.

Answer:

He payed 12,000 in one year

John has to pay $24000

Step-by-step explanation:

Car cost = $36,000

He gave Monthly = $1000

How much money did he give in a year?

1 year = 12 months

So

$1000 x 12 = 12,000

How does he have balance?

$36,000 - $12,000 = $24,000

John payed $12000 in one year, and has to pay $24000 more to own the car.

Jane is asked to buy some chickens, dogs and ducks for her farm. The total number of animals she needs to buy is 50. She has a budget of $1500 to spend on $20/chicken, $50/dog, and $30/duck. Additionally, the number of chickens should be equal to that of ducks. Create a system of 3 equations to model the situation. Assume the number of chickens is x, dogs is y and ducks is z.

Answers

Answer:

x = 20, the number of chickens as well as the number of ducks.

........

20 chickens, 20 ducks and 10 Dogs 50-20-20

And...checking

$400 + $600 + $500 = 1500

x the number of chickens as well as the number of ducks

20x + 30x + 50(50-2x) = $1500

-50x = -1000

Step-by-step explanation:

Hope this helps

The system of 3 equations to model the situation are;

x + y + z = 50

20x + 50y + 30z = 1500

x = z

How to write equation?

number of chickens = xnumber of dogs = ynumber of ducks = zcost of each chicken = 20cost of each dog = 50cost of each duck = 30Total cost = 1500Total number of animals = 50

The equation:

x + y + z = 50

20x + 50y + 30z = 1500

number of chicken = number of ducks

x = z

Therefore, the equations are;

x + y + z = 50

20x + 50y + 30z = 1500

x = z

Select the correct answer. Which number is a zero of h(x) = (x2 − 81)(x + 4)
A. 0
B. 4
C. 9
D. 81

Answers

Answer:

9 is a zero of h(x). C. Correct

Step-by-step explanation:

We want to find the zeros of the function

[tex]h(x) = (x^2 - 81)(x + 4)[/tex]

The zeros are the values of x that make h(x)=0, thus we need to solve the equation:

[tex](x^2- 81)(x + 4)=0[/tex]

Factoring:

[tex](x^2 - 81)=(x-9)(x+9)[/tex]

[tex](x-9)(x+9)(x + 4)=0[/tex]

This equation has 3 solutions:

x=9, x=-9, x=-4

A. 0 is not a zero of h(x). Incorrect

B. 4 is not a zero of h(x). Incorrect

C. 9 is one of the zeros of h(x) calculated above. Correct

T1=5

let n be 2

2(2)+3

T2=7

T3=2(3)+3

=9

T4=2(4)+3

=11

A. For the sequence given by the nth term formula an = 2n + 3, the first four terms are:

a1 = 2(1) + 3 = 5

a2 = 2(2) + 3 = 7

a3 = 2(3) + 3 = 9

a4 = 2(4) + 3 = 11

For the sequence given by the nth term formula an = n² - 1, the first four terms are:

a1 = 1² - 1 = 0

a2 = 2² - 1 = 3

a3 = 3² - 1 = 8

a4 = 4² - 1 = 15

4. If two parallel lines are cut by a transversal, then complementary angles are congruent

Answers

the following are my reminders in using this module

  By the property of alternate interior angles, Option (1) is the correct statement.    

    From the figure attached,

∠XWY ≅ ∠ZYW

    Property of the alternate angles states, if two parallel lines are cut by a transversal, then the alternate angles are congruent.

By this property,

 Lines XW and YZ are the parallel lines intersected by a transversal WY.

Here, ∠XWY and ∠ZYW represent the interior angles between the parallel lines and the transversal.

 Therefore, interior alternate angles ∠XWY and ∠ZYW will be congruent.

Hence, Option (1) will be the correct option.
