Kyle has a aquarium in the shape of a rectangular prism.The aquarium is 24 inches long and 10 inches wide. The volume of the aqu
jasenka [17]
To calculate to volume of a rectangular prism you use the formula l × w × h = V

l, w, and h are the sides, and V is the volume

So... 24 × 10 × h = 2,880

h = 2,880 / 240

h = 12

The regression equation for change in temperature, y, to amount of humidity in
mr_godi [17]

Answer:

Residual = 11.462

Since the residual is positive, it means it is above the regression line.

Step-by-step explanation:

The residual is simply the difference between the observed y-value which is gotten from the scatter plot and the predicted y-value which is gotten from regression equation line.

The predicted y-value is given as 20.7°

The regression equation for temperature change is given as;

y^ = 9.1 + 0.6h

h is the observed amount of humidity and it's given to be 23 percent or 0.23.

Thus;

y^ = 9.1 + 0.6(0.23)

y^ = 9.238

Thus:

Residual = 20.7 - 9.238

Residual = 11.462

Since the residual is positive, it means it is above the regression line.

I think the answer is 38 degrees I just want someone to check if I am right please!
Aleksandr [31]

Answer:

JML = 142

Step-by-step explanation:

Sadly that is wrong.  Not all the angles are the same.  However, using the reflexive property we can find that angle JKM is 38 degrees.  Using this, we need to create an equation to get the other two angles.  Again, they would be the same because of the reflexive property.

38 + 38 + x + x = 360

The total needs to be 360 because the shape has 4 sides.

76+x^{2} =360

Now you beed to get the variable to one side.  To do this you would subtract each side by 76.

x^{2} =284

Finally, your answer currently shows the sum of both LKJ and JML.  to get one sides angle just divide by 2.

284 / 2 = 142

JML = 142

There is your answer.

Hope this helped.
