Answer: See explanation

Step-by-step explanation:

From the question, we are informed that the areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 and that the combined area of these three rooms is 189 square feet.

Therefore, Kitchen area = 4/(4+3+2) × 189 = 4/9 × 189 = 84 square feet

Playroom area = 3/(4+3+2) × 189 = 3/9 × 189 = 63 square feet

Dining room area = 2/(4+3+2) × 189 = 2/9 × 189 = 42 square feet

During taylor's experiment, which piece of data would be qualitative?
Reptile [31]

There isn't any piece of data during Taylor's experiment which can be taken as  qualitative. Thus, correct choice is: Option D: None are qualitative.

<h3>What is qualitative data?</h3>

Qualitative data tells about the quality or characteristic. It is tough to express it numerically or not at all expressible numerically. They are usually catagorical.

In contrast, there is quantitative data which can be expressed numerically.

The problem is missing its option, which are:

  1. mass of the cars
  2. degree of the ramp incline
  3. time in seconds
  4. none are qualitative

Mass can be measured (in kgs, grams etc), degree of inclination can be measured (in radians, degree etc), time can be measured (in seconds, minutes etc).

Thus, there isn't any piece of data during Taylor's experiment which can be taken as  qualitative. Thus, correct choice is: Option D: None are qualitative.

Madison has 64 circles and 96 squares and 48 triangles.What factors do these numbers have in common? A.1,2,4,8,or 16 B.1,2,4,6,1
cestrela7 [59]

Answer:

The correct answer is option A.

Step-by-step explanation:

Number of circles = 64

Number of square = 96

Number of triangles = 48

Factor of 64, 96  and 48;

64=2\times 2\times 2\times 2\times 2\times 2

96= 2\times 2\times 2\times 2\times 2\times 3

48= 2\times 2\times 2\times 2\times 3

Factors do these numbers have in common are:

64 = 2 × 2 × 2 × 2 × 2 × 2

96= 2 × 2 × 2  × 2 × 2 × 3

48= 2 × 2 × 2 × 2  × 3

Common factors = 2 × 2 × 2 × 2 =16
