5 0

Answer:

n = 2

Step-by-step explanation:

\sqrt{2n+28}-4\sqrt{n}=0\\\\\\\sqrt{2n+28} = 4\sqrt{n}\\\\

Take square,

(\sqrt{2n+28})^{2}=( 4\sqrt{n})^{2}\\\\ 2n + 28 = 16n\\\\28 = 16n -2n\\\\28 =14n\\\\14n=28\\\\n=\frac{28}{14}\\\\n=2

Angle x and y are complementary. Angle x is supplementary to a 128º angle.
tiny-mole [99]

Answer:

x = 52

y = 38

Step-by-step explanation:

Angle x is supplementary to a 128º angle.

Supplementary angles add to 180

x+128 = 180

Subtract 128 from each side

x+128-128 = 180-128

x =52

Angle x and y are complementary.  

Complementary angles add to 90

x+y =90

52+y =90

Subtract 52 from each side

52-52 +y = 90-52

y = 38

A data set is represented by the box-and-whisker plot below.
klio [65]

A box plot has 5 data descriptions. The correct option is 87 and 132.

<h3>How does a boxplot show the data points?</h3>

A box plot has 5 data descriptions.

  • The leftmost whisker shows the minimum value in the data.
  • The rightmost whisker shows the maximum value in the data.
  • The leftmost line in the box shows the first quartile.
  • The middle line shows the median, also called the second quartile.
  • The last line of the box shows the third quartile.

Since each quartile of the box-and-whisker plot represents 25% of the data. Therefore, values between which there are 3 quartiles present will represent 75% of the data.

Hence, the correct option is 87 and 132.

Fed [463]

Marco is wrong. In order for an input-output table to be a function, there can only be one Y for every X, meaning that X cannot repeat as the same number twice.
