What is Linear model?

A linear model is a model in which the terms are added, such as has been used so far in this section, rather than multiplied, divided, or given as a non-algebraic function. Linear modeling can predict the behavior of complex systems or analyze experimental, financial, and biological data.

Linear regression is a statistical method used to create a linear model. The model describes the relationship between a dependent variable y (also called the response) as a function of one or more independent variables Xi (called the predictors).

Given data ,

Weight of the puppies = y pounds

Number of weeks after birth = t

Linear model representing the relationship between weight of puppies and time after birth in weeks is y = 2.3 + 5.73t

This is a clear idea of Linear models because the data describe a continuous response variable as a function of one or more predictor variables.

Hence , this is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks

Answer:

7.2inches.

Step-by-step explanation:

Given parameters:

Radius of Circle A  = 6inches

Unknown:

Radius of circle B  = ?

Solution:

We are to find the radius of circle B.

  The relationship between circle A and B is such that;

    Radius of Circle B  = 20% greater than that of A

   Radius of Circle B  = 1.2 x 6  = 7.2inches.

Answer:

The answer is 11/6! Hope this helped!

Steps:

6/3 + (-1/6)

apply rule --> a + (-b) = a - b

6/3 + (-1/6) = 6/3 - 1/6

= 6/3 - 1/6

6/3 = 2

= 2 - 1/6

2 = 6 x 2 over 6

= 6 x 2 over 6 - 1/6

= 12/6 - 1/6

apply fraction rule --> a/c - b/c = a - b over c

12/6 - 1/6 = 12 - 1 over 6

= 12 - 1 over 6

= 11/6

Answer:

Step-by-step explanation:

Given the profit a club makes after paying for the bank and other costs modeled by the function

p(t) = -16t^2 - 800t - 4000

t is the ticket price

The maximum profit occurs when dp/dx = 0.

dp/dx = -32t-800

since dp/dx

0 = -32t-800

32t = -800

t = -800/32

t = - 25

Hence ticket price gives the maximum profit is $-25

b) to get the maximum profit, substitute t = -25 into the modelled function

p(t) = -16t^2 - 800t - 4000

p(-25) = -16(-25)² - 800(-25)- 4000

p(-25) = -10000+20000-4000

p(-25) = 6000

Hence maximum profit is $6000

c) To get the ticket prices would generate a profit of $5000, we will substitute p(t) = 5000 and find t

p(t) = -16t^2 - 800t - 4000

5000 = -16t^2 - 800t - 4000

-16t^2 - 800t - 4000 -5000 = 0

16t^2 + 800t + 9000 = 0

Answer:

Step-by-step explanation:

Given the profit a club makes after paying for the bank and other costs modeled by the function

p(t) = -16t^2 - 800t - 4000

t is the ticket price

The maximum profit occurs when dp/dx = 0.

dp/dx = -32t-800

since dp/dx

0 = -32t-800

32t = -800

t = -800/32

t = - 25

Hence ticket price gives the maximum profit is $-25

b) to get the maximum profit, substitute t = -25 into the modelled function

p(t) = -16t^2 - 800t - 4000

p(-25) = -16(-25)² - 800(-25)- 4000

p(-25) = -10000+20000-4000

p(-25) = 6000

Hence maximum profit is $6000

c) To get the ticket prices would generate a profit of $5000, we will substitute p(t) = 5000 and find t

p(t) = -16t^2 - 800t - 4000

5000 = -16t^2 - 800t - 4000

-16t^2 - 800t - 4000 -5000 = 0

t^2 + 50t + 562.5= 0

Factorize

-50±√2500-4(562.5)/2

t = -50±√2500-2250)/2

t = -50±15.81/2

t = -65.81/2 and -34.19/2

t = -32.91 and -17.09

Answer:

+$90;

$1,600

Step-by-step explanation:

The equation, [tex] y = 1600 + 90x [/tex], given to us tells us much about the situation described above.

y = total pay

x = number of copies of Math is fun

1600 = y-intercept, that is the starting value or the pay he gets only if Sam sold 0 copy of Math is fun. That is, when x = 0, y = 1,600.

90 = unit rate or the change in the total pay for each copy of Math is fun that Sam sells.

Therefore, our answers would be:

+$90, and $1,600

Answer:

She saved 25% or 1/4

Step-by-step explanation:

Please give me brain

Answer:

Her change was: $3.5

Step-by-step explanation:

Mary bought a shirt on sale for $15.00.

As the sales tax was 10%.

i.e. 10/100 × 15 = $1.5

so the sales tax on $15.00 was $1.5.

Hence, the total cost Mary had to pay to buy the shirt was:

$1.5 + $1.5 = $16.5

As Mary paid with a $20 bill, therefore the change can be calculated as

20 - 16.5 = $3.5.

Therefore, her change was: $3.5

A altura máxima é 5

Step-by-step explanation:

Matematicamente, a altura máxima pode ser obtida

A altura máxima é simplesmente o vértice da parábola

Começamos diferenciando a função Isso será -8x

Agora, defina -8x como 0

Isso significa que x = 0

Agora, substitua x = 0 de volta na equação temos

f (0) = -4 (0) ^ 2 + 5

f (0) = 5

Answer:

g(x) = [tex]4^{(x-1)}+3[/tex]

Step-by-step explanation:

Given exponential function is,

f(x) = [tex]4^{x}[/tex]

If the given function is shifted 1 unit to the right,

h(x) = f(x - 1)

      = [tex]4^{(x-1)}[/tex]

If the function 'h' is shifted 3 units up,

g(x) = h(x) + 3

      = [tex]4^{(x-1)}+3[/tex]

Therefore, transformed function will be,

g(x) = [tex]4^{(x-1)}+3[/tex]

Answer:

y=5x+3

Step-by-step explanation:

First, we need to find the slope. Remember that the slope equation is [tex]m=\frac{y2-y1}{x2-x1}[/tex].

If we plug in the given points we get m=5. (let me know if you need further elaboration on this step)

So now that we have a slope, we can plug it into the slope-intercept equation.

y=mx+b

y=5x+b

We still need to find b (y-intercept), but luckily, we were given two points that we could plug in. I'm going to use (1,8) here.

8=5(1)+b

8=5+b

b=3

Now we have all of our parts and can put them into the equation.

y=5x+3
