The confidence interval is based on mean square error. The mean squared error (MSE) of an estimator measures the average of the squares of the errors or deviations. MSE is calculated by the formula attached in the picture, where Xbar is a vector of predictions, X is the vector of predicted values.

Denver gets 5/19 of the dog food.

natka813 [3]

Answer:

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

Step-by-step explanation:

If Denver gets $\frac{5}{19}$ of the dog food, then Engle and Fido share $\frac{14}{19}$ of the dog food. If Fido have $x$ of the dog food, then Engle have $\frac{4}{3}\cdot x$ such that:

$x + \frac{4}{3}\cdot x = \frac{14}{19}$

$\frac{5}{3}\cdot x = \frac{14}{19}$

$x = \frac{42}{95}$

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

sveta [45]

Answer:

1.x^2

2.x+8

3.x

4. 8x

Step-by-step explanation:

Length of old is x inches.

Because it is square we have that area of the old canvas : $x^2$

When we read : width of new is increased by 8 so : x+8

Length is x.

The difference of areas:

Old canvas : A1= $x^2$

New canvas : $A2=x(x+8)=x^2+8x$

Now we can find A2-A1:

$x^2+8x-x^2=8x$
