By visual inspection ,determine the best fitting regression model for the scatter plot

Mathematics
1 answer:
k0ka [10]2 years ago
5 0

Answer:

if the scatter plot has a curve like the one attached does then it is quadratic  regression.

Step-by-step explanation:

Exponential growth is a specific way that a quantity may increase over time. ... Described as a function, a quantity undergoing exponential growth is an exponential function of time, that is, the variable representing time is the exponent (in contrast to other types of growth, such as quadratic growth).

Exponential growth is a specific way that a quantity may increase over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself.

This means if it has a curve that doesn't represent same value proportions to another axis. that is different to exponential then we say it is quadratic regression.

The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship.

the angle of elevation of the top of a building from a point 80 ft away from the building on level ground is 70° determine the b
MA_775_DIABLO [31]
Draw a triangle with shortest side on the ground (horiz.).  The length of this side is 80 feet.  Two angles touch the ground:  a right angle, and the 70 degree angle.
 
Then the height of the building is the 2nd shortest side.

The tangent function is the appropriate one to use here:
                       opp          h
tan 70 deg = -------- = ----------
                        adj        80 ft
                                                                h
Since tan 70 deg  = 2.75,          2.75 = -------
                                                              80 ft

so h = building height = (80 ft)(2.75) = 219.8 ft

Solve for X and y PLEASE GIVE FULL EXPLANATION HOW YOU GOT IT
Dennis_Churaev [7]

Answer:

(1, -1)

Step-by-step explanation:

we isolate y in the first equation

2x+y=1

-2x.  -2x

y=1-2x

and now we fill y into second equation

4x-2(1-2x)=6

4x-2+4x=6

8x-2=6

   +2 +2

8x=8

/8 /8

x=1

and now to find y we insert x

2(1)+y=1

2+y=1

-2.   -2

y= -1

hopes this helps

Express in the form <br> 1<br> :<br> n<br> .<br> Give <br> n<br> as a decimal.<br> 10<br> :<br> 4
Brut [27]

Answer:

n=0.4

Step-by-step explanation:

10:4=5:2

to make 5 as 1, we will divide both 5 and 2 by 5

<h3>\frac{5}{5}:\frac{2}{5}=1:n</h3><h3>therefore, n=\frac{2}{5} = 0.4</h3><h3 /><h3>                                           </h3>
