Answer:

A) This is a self-interest study.

Step-by-step explanation:

Given is that a shampoo company recently paid a consulting firm to produce a study to determine if using their product resulted in cleaner hair than other brands.

We can see that this study is based on the self interest of the shampoo company.

Therefore, the thing wrong with this study is that it is a self-interest study.

Find the radius of a circle whose area equals the area of a rectangle that measures 2 ft. by 11 ft. (Use = 22/7). . . r = SQRT _
const2013 [10]
The area of a rectangle is calculated through the equation, V = L x W. That of the circle is equal to V = πr². These areas should be equal,
                                  V = L x W = πr²
Substituting the known values,
                               2 ft x 11 ft = (22/7)(r²)
The value of r is sqrt 7.

Chelsea dog-sits for her neighbors as a part-time job. She charges $12 a day plus an additional $2.50 for each walk she takes wi
11111nata11111 [884]

The equation that represents the amount earned is y = 12 + 2.5x

<h3>How to determine the equation?</h3>

The given parameters are:

  • Chargers per day = $12
  • Charges per walk = $2.5 per walk

Let the number of walks be x and the total charges per day be y.

So, we have:

y = 12 + 2.5x

Hence, the equation that represents the amount earned is y = 12 + 2.5x

See attachment for the graph
