Answer:

The residual for 5 is -1.6

Step-by-step explanation:

A residual value is the difference between the observed y-value and the predicted y-value( from the regression equation ) .

Here, the given regression equation of the line,

y = 5.2 x - 0.4

Thus, for x = 5, the predicted value of y = 5.2 × 5 - 0.4 = 26.0 - 0.4 = 25.6,

Now, by the given table,

For x = 5, the observed value of y = 24,

Hence, the residual for 5 = Observed value of y for 5 - Predicted value of y for 5

= 24 - 25.6 = - 1.6

⇒ First option is correct.

Howard has a scale model of the Statue of Liberty. The model is 15 inches tall. The scale of the model to the actual statue is 1

sergiy2304 [10]

Answer:

Required equation $\frac{1}{6.2}=\frac{15}{x}$

The height of statue of liberty is 93 meters.

Step-by-step explanation:

Given : Howard has a scale model of the Statue of Liberty. The model is 15 inches tall. The scale of the model to the actual statue is 1 inch : 6.2 meters.

To find : Which equation can Howard use to determine x, the height in meters, of the Statue of Liberty?

Solution :

The model is 15 inches tall.

The scale of the model to the actual statue is 1 inch : 6.2 meters.

Let x be the height in meters of the Statue of Liberty.

According to question, required equation is

$\frac{1}{6.2}=\frac{15}{x}$

Cross multiply,

$x=15\times 6.2$

$x=93$

Therefore, the height of statue of liberty is 93 meters.

The floor of a rectangular room will be tiled with square tiles that measure 3 inches on each side. The room is 109 inches long

Fynjy0 [20]

Find the total area of the room
109 * 103 = <span>11227 inches^2
the tile takes up 3*3 = 9 inches^2
11227/9 = </span><span>1247.4
You need 1247 tiles and 0.4 of a tile.
Or you could just get 1248 and cut the last tile a bit :P

Hope this helps :)</span>

8h+(-6.3d)-15+4d-3.3h

Drupady [299]

Answer:

Not exactly sure if you are asking to simplify, but that is all I can do with the information you have given.

Here is the simplified version:

−2.3d + 4.7h − 15

Step-by-step explanation:

Combine Like Terms:

=8h+−6.3d+−15+4d+−3.3h

= (−6.3d+4d) + (8h+−3.3h) + (−15)

= −2.3d+ 4.7h − 15
