Pineapples were packed in three large crates. for each crate, the weight of every pineapple in the crate was recorded. here are
1 answer:
- The correct statements are:
the weights of the pineapples in crate 1 were the most variable. - The heaviest pineapple was in crate 1.
- More than half the pineapples in crate 1 and crate 3 were heavier than the heaviest pineapple in crate 2.
A box plot is used to study the distribution and level of a set of scores. The box plot consists of whiskers which measure the minimum and maximum numbers. The difference between these numbers is the range which measures variability.
On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile. The difference between the first quartile and the third quartile is the interquartile range.
For the first box plot:
- Maximum number = 6
- Minimum number = 1.5
- Range = 6 - 1.5 = 4.5
- Median = 4
- First quartile = 3
- Third quartile = 4.5
- IQR = 4.5 - 3 = 1.5
For the second box plot:
- Maximum number = 3.5
- Minimum number = 1
- Range = 3.5 - 1 = 2.5
- Median = 2
- First quartile = 1
- Third quartile = 2.5
- IQR = 2.5 - 1 = 1.5
For the third box plot:
- Maximum number = 5
- Minimum number =2.5
- Range = 5 - 2.5 = 2.5
- Median = 4
- First quartile = 3.5
- Third quartile = 4.5
- IQR = 4.5 - 3.5 = 1

Answer:
Since the pentagon is regular, the line connecting the centre of the circle to the verticles (A,B,C,D,E) should inscribe an equal angle in them
You can see what I mean in the attachment
So to mark other points we follow the following steps
- Connect OA
- With OA as base, make angle of 72°. Say th new line is OB.
- Similarly, do for the rest of them
- This is a cyclic pentagon

Answer:
- 615.8 m^2
- 314.2 cm^2
- 38.5 ft^2
- 113.1 in^2
- 1075.2 m^2 . . . . corrected to 107,521.0 m^2
- 490.9 yd^2
- 18.8 m
- 94.2 in
- 81.7 ft
- 59.7 km
- 131.9 cm
- 144.5 yd
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr^2
For each of the given circles, use the value of the radius in this formula. For example, for problem 2, the diameter is shown as 20 cm, so the radius is half that, 10 cm. Putting that value into the formula gives ...
A = 3.14159·(10 cm)^2 = 314.159 cm^2 ≈ 314.2 cm^2
___
The formula for the circumference of a circle is ...
C = 2πr . . . . when the radius is given
or ...
C = πd . . . . . when the diameter is given
As above, put the value for radius (or diameter) into the appropriate formula and evaluate it. For problem 12, that is ...
C = 3.14159·(46 yd) = 144.513 yd ≈ 144.5 yd

<em>Comment on doing lots of problems</em>
The idea behind having you do lots of problems is that repetition will help you remember the formula and/or how to use it. Personally, I find it tedious, so I like to let a spreadsheet or graphing calculator do the arithmetic when there are lots of identical problems (just with different numbers). This question is posted in the college math forum, so we assume you have a graphing calculator and know how to use it.
The attached photo shows a calculator set up to do the calculation and the rounding for each of the problem types. To get the answer to the last area calculation requires scrolling to the right to find it is 490.9 yd^2.
Note that we have used the calculator's button for π. If you put the number in yourself, use the one shown above, or the ratio 355/113, which is accurate to 7 digits.
In some cases, the numbers in the photo are not terribly clear. I took my best guess. In the event I read the value or units incorrectly, you will have to make appropriate adjustments—that is, do the calculation yourself.

Late edit: apparently I read the number wrong for problem 5. The area of a circle with radius 185 m is 107,521.0086 m^2, which rounds to 107,521.0 m^2. Oops.
