Answer:

  (b)  60

Step-by-step explanation:

The external angle is half the difference of the two subtended arcs.

  x° = (172° -52°)/2 = 120°/2

  x° = 60°

The value of x is 60.

Pineapples were packed in three large crates. for each crate, the weight of every pineapple in the crate was recorded. here are
IRISSAK [1]
  • 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.

<h3>What are the correct statements?</h3>

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

the radius of one circular field is 5m and that of other is 3m.find the radius of circular field whose area is the difference of
Alex777 [14]

Answer:

4m

Step-by-step explanation:

  1. Recall the formula for area of a circle for each calculation
  2. Calculate the area of the large field (r = 5m)
  3. Calculate the area of the small field (r = 3m)
  4. Find the difference in area
  5. Find the radius of the "difference" field using difference in area

The formula for area of a circle is A = πr².

"A" means area.

π is pi. <em>I will use the π button</em>, but some teachers ask to use 3.14.

"r" means radius.

Area of large field:

Substitute "r" for 5m in the formula.

A = πr²

A = π(5m)²

A = π25m²

A = 78.5398163397 m²

Area of small field:

Substitute "r" for 3m in the formula.

A = πr²

A = π(3m)²

A = π9m²

A = 28.2743338823  m²

Difference in areas:

Subtract the area of small field from the area of large field.

(78.5398163397 m²) - (28.2743338823  m²)

= 50.2654825 m²

Radius of "difference" field:

Since we are looking for radius, not area, rearrange the formula to isolate "r".

A = πr²

\frac{A}{\pi } = \frac{\pi r^{2}}{\pi}     Divide both sides by π

\frac{A}{\pi } = r²                π cancels out on the right side

\frac{A}{\pi } = √r²             Square root both sides

\sqrt{\frac{A}{\pi }} = r        ² and √ cancel out, leaving "r" isolated

r = \sqrt{\frac{A}{\pi }}       Variable on the left for standard formatting

Substitute "A" for the difference in area

r = \sqrt{\frac{A}{\pi }}

r = \sqrt{\frac{50.2654825m^{2}}{\pi }}     Divide by pi first

r = \sqrt{16.0000000135&#10;m^{2}}            Find the square root

r ≈ 4m

The radius of the field that has the area of the difference in the two fields is 4m.
