Answer:

x = -1/2

Step-by-step explanation:

2x + 4y = 13

3x + y = 2    (you can multiply this equation by -4 in order to eliminate the y-term)

-4(3x + y = 2)  =  -12x - 4y = -8

                        +  <u>2x + 4y = 13</u>

-10x = 5

x = -5/10 or -1/2

x(-1/2) + 4y = 13

-1 + 4y = 13

4y = 14

y = 14/4 or 7/2 or 3 1/2

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
