Finding the Median from a Dot Plot
MAXImum [283]

Answer:

median rainfall for highland storms = 18mm

median rainfall  for lowland storms = 18mm

or

median rainfall  for lowland storms = 17mm if the list of numbers is

2  4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

Step-by-step explanation:

The median is the middle number of a sequence of ordered numbers.

The formula for the median is:

median = (n + 1 )/ 2

where n = total number of values

Note: the number that you find with this formula is the position. SO you have to go to the sequence of numbers and find the number that lies in that position.

Highland storms:

4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

The numbers are already in ascending order so we can proceed.

n = 15

∴ median = (15+1)/2

                = 16/2

                = 8

The median is the umber in the 8th position

so, the median rainfall for highland storms is 18mm

Lowland storms:

4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

The numbers are already in ascending order so we can proceed.

n = 15

∴ median = (15+1)/2

                = 16/2

                = 8

The median is the number in the 8th position.

∴  median rainfall for lowland storms is = 18mm

<u>Unclear: if this is the list of numbers: </u>

2  4 6 8 10 12 14 16 18 20 22 24 26 28 30 32

then the median would be:

n = 16

median = (16+1)/2  

             = 17/2

             = 8.5

This means the median lies between the numbers in the 8th and 9th position.

∴ The median is =  (16 + 18)/2

                           = 34/2

                           = 17

At noon, ship A is 170 km west of ship B. Ship A is sailing east at 35 km/h and ship B is sailing north at 20 km/h. How fast is
garik1379 [7]
Check the picture below.

now, keep in mind that ship B is going at 20kph, thus from noon to 4pm, is 4 hours, so it has travelled by then 20 * 4 or 80 kilometers, thus b = 80.

whilst the ship B is moving north, the distance "a" is not really changing, and thus is a constant, that matters because the derivative of a constant is 0.

\bf c^2=a^2+b^2\implies \stackrel{chain~rule}{2c\cfrac{dc}{dt}}=0+2b\cfrac{db}{dt}\implies \cfrac{dc}{dt}=\cfrac{b\frac{db}{dt}}{c}&#10;\\\\\\&#10;\begin{cases}&#10;\frac{db}{dt}=20\\&#10;c=10\sqrt{353}\\&#10;b=80&#10;\end{cases}\implies \cfrac{dc}{dt}=\cfrac{80\cdot 20}{10\sqrt{353}}\implies \cfrac{dc}{dt}=\cfrac{160}{\sqrt{353}}&#10;\\\\\\&#10;\textit{and rationalizing the denominator}\implies \cfrac{160\sqrt{353}}{353}

ake and Nico both measured their thumbs. Jake’s thumb is 55 millimeters long. Nico’s thumb is 5.7 centimeters long. Who has the
qaws [65]

Answer:

Nico

Step-by-step explanation:

We have to convert both to the same units! Think about the units: we have millimeters and centimeters. There are 10 millimeters in a centimeter, so

55 mm = 5.5 cm

We just had to move the decimal point!

Now compare the two measurements in cm. 5.5 and 5.7: which is greater? Look at the tenths place: 5<7, so 5.7 is greater and Nico’s thumb is longer!

Choose the inequality that represents the following graph.HELP HELP HELP
Wewaii [24]

Solution:

<u>It should be noted:</u>

  • If the starting point of the inequality is half shaded, the sign will be < or >.
  • If the starting point of the inequality is fully shaded, the sign will be ≤ or ≥.

<u>We can tell that:</u>

  • The inequality will either have an < or > sign.
  • The blue line tells us that the value of x must be greater than -1.

This clearly tells us that the inequality is x > -1

<u>In conclusion:</u>

Option C is correct.
