Determine whether it is possible to form a triangle using each set of segments with the given measurements.

1 answer:

8 0

Are we talking about edges or the physical sides of the triangle?

If edges (corners / angles of the triangle), then no, because it doesn’t add up to 180. I don’t think the measurements of the sides matter, tho.

Answer: $\$4.34$

Step-by-step explanation:

We have the following information:

Fredburguer $F$ , milkshake $M$ and an order of fries $f$ costs $\$3.72$ :

$F+M+f=\$3.72$ (1)

One Fredburguer is equal to a milkshake plus orders of fries:

$F=M+2f$ (2)

Three milshakes is equal to a Fredburguer plus an order of fries:

$3M=F+f$ (3)

And we are asked: If we have a Fredburguer, a milkshake and two orders of fries, how much do we have to pay?

$F+M+2f=x$ (4)

Well with the first three equations we have a system of equations to solve. Let's begin by isolating $F$ from (3):

$F=3M-f$ (5)

Making (2)=(5):

$M+2f=3M-f$ (6)

Isolating $f$ :

$f=\frac{2}{3}M$ (7)

Substituting (7) in (2):

$F=M+2(\frac{2}{3}M)$ (8)

Isolating $F$ :

$F=\frac{7}{3}M$ (9)

Substituting (7) and (9) in (1):

$\frac{7}{3}M+M+\frac{2}{3}M=\$3.72$ (10)

Isolating $M$ :

$M=\$0.93$ (11) This is the cost of a Milkshake

Substituting (11) in (7):

$f=\frac{2}{3}\$0.93$ (12)

$f=\$0.62$ (13) This is the cost of an order of frieds

Substituting (11) in (9):

$F=\frac{7}{3}\$0.93$ (14)

$F=\$2.17$ (15) This is the cost of a Fredburguer

Substituting (11), (13) and (15) in (4):

$\$2.17+\$0.93+2(\$0.62)=x$ (16)

Finally:

$x=\$4.34$ This is the cost of a Fredburguer, a milkshake and two orders of fries

What is a fitted value for a multiple regression model and the data that is used to create it?

densk [106]

Fitted value is a prediction of the mean response value.

According to the statement

we have to explain the fitted value for the regression model and the data which uses to collect the value.

So, For this purpose, we know that the

A Fitted value is a statistical model's prediction of the mean response value when you input the values of the predictors, factor levels, or components into the model.

An the fitted value used in this model is called the predicted values of response variable in the case of multiple regression model.

And data which is used to create the fitted value is the simple data by which we create the fitted value by the predict the value of given data.

So, Fitted value is a prediction of the mean response value.

The number of 8 oz glasses of milk in 1 gallon doesn't change and isn't a variable. Definitely answer NO to this one. With some reservations, I'd say that all the other three descriptions rate a YES.
