Answer:
its the second one
Step-by-step explanation:
To find the area of a <em>rectangle</em>, we multiply its length by its width. A square is a special case of a rectangle where all of the sides have the same length, so what we're really doing is taking the side length and multiplying it by itself. Fittingly, we call the process of multiplying a number by itself <em>squaring </em>that number. For example, "3 squared," - written as 3² - gives us 3 x 3 = 9, 4² gives us 4 x 4 = 16, and hopefully you get the idea from there.
Here, a square with a side length of 6.25 feet would have any area of (6.25)² <em>square feet</em> (because area takes up <em>space, </em>we can't measure it with length alone - we need to use something else that takes up space, and squares are the simplest type of shape for the job).
Doing the calculation, we find that this is (6.25)(6.25) = 39.025 square feet.
Answer:
A. The explanatory variable is the number of items viewed. This explanatory variable is quantitative.
Step-by-step explanation:
The variable that we can change is called the Explanatory Variable.
The Response variable depends upon the explanatory variable, as we change the value of the explanatory variable the value of the response variable is also get changed.
When the data is in the form of numeric, it is called quantitative.
When the data is not in the numeric form, it is called qualitative.
Here, we have to determine which web page design is better and it depends on the number of the item viewed by a visitor to that site.
Thus, the Explanatory variable is the "number of items viewed".
and the number of items viewed is numeric data, so it is quantitative.
Hence, option (A) is correct.
This is usually used as a proof that triangles have 180°. Look at the attached figures. If you cut off angle A, angle B and angle C and rotate them so that their vertices touch, you form a half-circle out of them (or a straight line). We know that half a circle is 1/2 of 360° or 180; therefore all 3 angles in a triangle must add up to 180°.
