The equation of the linear regression  is \^ y = 3.58125\^x + 202.575

<h3>Graphing tool</h3>

To determine the line of best fit, we make use of a graphing tool

See attachment for the graph of the line of best fit

<h3>The equation</h3>

From the graphing tool, we have the following calculation summary

  • Sum of X = 440
  • Sum of Y = 3601.5
  • Mean X = 44
  • Mean Y = 360.15
  • Sum of squares (SSX) = 1440
  • Sum of products (SP) = 5157

The regression Equation is then represented as:

\^y = b\^x + a

Where:

b = \frac{SP}{SSX} and a = \bar y - b \times \bar x

b = \frac{5157}{1440}

b = 3.58125

Also, we have:

a = \bar y - b \times \bar x

a= 360.15 - (3.58\times 44)

a = 202.575

So, the linear regression equation is:

\^ y = 3.58125\^x + 202.575

Answer:

the triangle above is an isoceles triangle

therefore the base angles are equal

So we have:

X + X + 38= 180

2x = 180-38

2x = 142

X = 71°

WHAT IS GREATER 0.5L OR 400ML
bogdanovich [222]

Answer:

0.5 liters is greater than 400 milliliters.

Step-by-step explanation:

Just, consider the conversion!

100 milliliters = 0.1 Liters

So, 400 milliliters would be equal to 0.4 liters, which is less than 0.5 liters.

0.5 Liters = 500 milliliters

Given f(x) = 6(1 - x), what is the value of f(-8)?
Vedmedyk [2.9K]

Answer:

<h2>f(-8) = - 42</h2>

Step-by-step explanation:

f(x) = 6(1 - x)

To find f(-8) substitute the value of x that's - 8 into f(x) that is for every x in f (x) replace it with - 8

We have

f(-8) = 6( 1 - 8)

= 6(-7)

We have the final answer as

<h3>f(-8) = - 42</h3>

Hope this helps you
