Answer:
independent quantitative.
Step-by-step explanation:
An indepentent variable in an investigation, is the variable that will be changed in order to know how its variation affects the dependent variable.
In this case, the dependent variable is the test scores since Dr Washington will study there is the numeber of hours of study affects the grade the students obtain.
Therefore, the hours of study are the independent variable.
It is also a quantitative variable since it can be counted.
In not so complicated math problems, a rough estimate or mentally-calculated estimate, sometimes referred to as a "ballpark estimate," helps to predict the numerical range the final answer should fall within. For example, if the given problem is to determine the sum of 23 plus 76, it can be estimated that the final and precise answer will be somewhere close to 100 because the known calculation 25 plus 75 equals 100 is close to the given problem 23 plus 76.

Step-by-step explanation:
The area of the first, second, third, and fourth circles will be 56.72 cm², 36.3 ft², 167.33 m², and 188.6 yd² respectively.
<h3>What is a circle?</h3>
It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
Then the radius and diameter are given below.
Then the area of the circle is given as
Area = π × r²
Then the area of the first circle will be
Area = π × r₁²
Area = 3.14 × 4.25²
Area = 56.72 square cm
Then the area of the second circle will be
Area = π × r₂²
Area = 3.14 × 3.4²
Area = 36.3 square ft
Then the area of the third circle will be
Area = π × r₃²
Area = 3.14 × 7.3²
Area = 167.33 square m
Then the area of the fourth circle will be
Area = π × r₁²
Area = 3.14 × 7.75²
Area = 188.6 square yd

The answer is True.
A compound event is one in which there is more than one possible outcome. It is also defined as a probabilistic event with two or more favorable outcomes. For example, when you throw a die (singular for dice), it is called a simple event. On the other hand, when you throw a dice, it is known as a compound event.
