The mean is greater than the median
enyata [817]3 years ago
6 0

Answer: mean > median

Step-by-step explanation:

The given data : 11, 11, 12, 13

The mean of the given data set is given by :-

\text{Mean}=\frac{\text{Sum of all elements}}{\text{number of all elements}}\\\\\Rightarrow\ \text{Mean}=\frac{11+11+12+13}{4}\\\\\Rightarrow\ \text{Mean}=\frac{47}{4}\\\\\Rightarrow\ \text{Mean}=11.75

To find median, first arrange them in ascending order  and since the number of elements is a even number(n=4), therefore,

Median=\frac{\frac{n}{2}\ term+(\frac{n}{2}+1)\ term}{2}

\frac{n}{2}\ term=\frac{4}{2}\ term=2nd\ term=11

\frac{n}{2}+1\ term=\frac{4}{2}+1\ term=3rd\ term=12

Median=\frac{11+12}{2}=\frac{23}{2}=11.5

Since, 11.75>11.5

Therefore, mean > median

Dr. Hilton uses the graph to determine if a patient has a
seropon [69]

Answer:

At least 100 degrees

Step-by-step explanation:

Here, we want to make an inequality assertion from the graph drawn by Dr Hilton.

The correct conclusion here is that a person has a fever once his/her temperature is greater than or equal to 100 degrees.

How do we know this from the graph? from the graph, we can see a yellow circular mark placed on 100. This indicates that we are starting our consideration from the point 100 degrees. What we don not know is if our answer is less than, greater than, less than or equal to or greater than or equal to.

The correct answer is however greater than or equal to. Firstly we check the fill of the yellow circular mark. Once it is filled and not left blank, then it indicates an equal to relationship, meaning 100 degrees itself is included in the range.

finally we then consider the direction it faces and from here we can conclude that it is greater than or equal to

Benjamin is trying to find the height of a radio antenna on the roof of a local building.
xz_007 [3.2K]

The height of the antenna on the roof of the local building is approximately 8 meters.

The situation forms a right angle triangle.

<h3>Properties of a right angle triangle:</h3>
  • One of its angles is equals to 90 degrees
  • The sides of the triangles can be calculated using Pythagoras theorem.

Therefore, let's find the height of the building and the radio antenna from the eye point.

Using trigonometric ratios,

tan 40° = opposite / adjacent

tan 40° = x / 25

where

x = the height of the building and the radio antenna from the eye point.

x = 25 tan 40

x = 25 × 0.83909963117

x = 20.9774907794 meters

Let's find the height of the building from his eye point.

tan 28° = y / 25

where

y = height of the building from his eye point

y = 25 × tan 28°

y = 25 × 0.53170943166

y = 13.2927357915 meters

Height of the antenna = 20.9774907794 - 13.2927357915 = 7.68475498786

Height of the antenna ≈ 8 meters

There is a 50% chance a coin lands on heads and a 50% chance the coin lands on tails what is the probability that the coin lands
Olegator [25]

Since the probability of the coin landing leads is 1/2, simply cube 1/2 to arrive at your answer: 1/8.


You cube 1/2 because you must land heads three times in a row and each flip is independent from other flips.
