Answer:

y = -228.29 + 4.013x

Step-by-step explanation:

Defining

x: Quantity of calories in the beef hot dogs

y: Content of sodium in the beef hot dogs

The least squares regression line equation is:

y = \beta_{0} + \beta_{1}x

Where

\beta_{1} = \frac{r\sigma_{y}}{\sigma_{x}}

\beta_{0} = \bar{y} - \beta_{1} \bar{x}

\beta_{1} = \frac{(0.887)(102.43)}{(22.64)}

\beta_{1} = 4.013

\beta_{0} = 401.15 - (4.013)(156.85)

\beta_{0} = -228.29

Then the regression’s equation is:

y = -228.29 + 4.013x

Please help anyone please

To solve the problem, we need to find the area of the triangle, and then find 2/3 of that triangle.

The equation to find the area of a triangle is bh1/2 or base*height*1/2.

Now substitute the known values.

24*16*1/2

Solve

24*8

192.

Now, the easiest way to find 2/3 of a number is to divide that number by 3 and multiply the answer by 2.

192/3=64

64*2=128

Omar kept 128 square centimeters of the flag.
