Please use the following data to build a regression model and write a summary. IV is sugar and DV is calories.
PilotLPTM [1.2K]

Answer:

y = 3.0453 + 29.1542x

Step-by-step explanation:

Given the data:

Sugar (X) : 5, 8, 9, 10, 15, 18, 14, 17, 20, 22, 24, 26, 30 ,30, 32

Calories (Y) : 20, 30, 60, 70, 100, 95, 70, 83, 103, 112, 130, 80, 95, 130, 112

To obtain the regression model :

General form of a regression equation :

y = c + mx

y and x are the dependent and independent variables ;

m = slope ;

Thus ;

Regression model for the data above is:

y = 3.0453 + 29.1542x

Find the volume of this prism.<br> Please help!! And explain &lt;3
olga nikolaevna [1]

(9×6/2) × 12 = 324

Explination:

The easiest way to understand what you're doing is to find the area of the base first, then extend it upwards to find the volume using height. Hence the equation: b×h=v

So how do we find the base of a triange? Remember that every single triangle can be calculated as a square, then cut in half. So 9 × 6 / 2 = 27 cm2

The next step is to calculate the volume using the height of the figure. 27 × 12 = 324 cm3

**<em>remember to </em><em>use</em><em> </em><em>the</em><em> </em><em>correct</em><em> </em><em>units</em><em>,</em><em> </em><em>since</em><em> </em><em>area</em><em> </em><em>and</em><em> </em><em>volume</em><em> </em><em>are</em><em> </em><em>different</em><em>. </em>

4688-3) -30X-5 CX-5)
pshichka [43]

Answer:

x = 13/3

Step-by-step explanation:

4(8x-3) - 30x = 5(x-5)

Distribute

32x - 12 - 30x  = 5x -25

Combine like terms

2x -12 = 5x-25

Subtract 2x from each side

2x-12-2x = 5x-2x -25

-12 = 3x-25

Add 25 to each side

-12+25 = 3x-25+25

13 = 3x

Divide each side by 3

13/3 = x
