There were 210 starlings, just multiply 42 by 5.
Answer:
10026 m²
Step-by-step explanation:
Since there are two semicircles attached to the rectangle, we can just say that that is one circle.
1. The area of the rectangle:<em> length * width = 60 * 120 = 7200 m²</em>.
2. The area of the circle: πr²
a. The radius of the circle: Since the circle is attached to the end of the rectangle, that means that the diameter would be the same length as the width. So, it would be 60 m, therefore, <em>the radius is 30 m</em>.
b. πr² = 3.14*30² = 3.14*900 = <em>2826 m²</em>.
3. Total: 2826 + 7200 = 10026 m².
For this example the range is 8 - 0 = 8. The interquartile range is 6.5 - 1.5 = 5.
The range is the better measure of variability because the data is arranged so that the spread of data is about the same from the beginning to the end.
There are not more numbers that fall in the middle half of the data when compared to the entire data set.
Answer:
9
Step-by-step explanation:
In the orange row there are 4 whole faces and one half face, thus
number of students = (4 × 2) + 1 = 8 + 1 = 9
