1. the most frequently occurring number(s) in a set of data ⇒ Mode
2. the smallest and largest values in a data set ⇒ Extreme values
3. the smallest value in a data set ⇒ Minimum
4. the difference between the largest and smallest data points ⇒ Range
5. the largest value in a data set ⇒ Maximum
6. the middle value of a set of data arranged in numerical order ⇒ Median
<u>Step-by-step explanation:</u>
The term "Minimum" is defined as the smallest value in the data set.
- For example : Consider a data set {1,2,3,4,5}.
- Here, the minimum is 1.
The term "Maximum" is defined as the largest value in the data set.
- For example : Consider a data set {1,2,3,4,5}.
- Here, the maximum is 5.
The term "Range" is defined as the difference between the largest and smallest data points in the data set.
- For example : Consider a data set {1,2,3,4,5}.
- To find the range : (Largest value - smallest value).
- Range ⇒ 5 - 1 = 4. Here, the Range is 4.
The term "Median" is the middle value of the set data after arranging it in the ascending order.
- For example : Consider a data set {6,3,2,4,1,5}.
- To find the Median : Arrange the data set in the ascending order.
- Therefore, the modified data set is {1,2,3,4,5,6}.
- Now, the middle term in the above data set is 4.
The term "Mode" is defined as the most repeated numbers in a data set.
- For example : Consider a data set {1,2,4,4,5}.
- To find the Mode : look for the most repeated number in the data set.
- Here, the number 4 is repeated two times. Therefore, mode is 4.
The term "extreme values" is defined as the smallest and the largest values in a data set.
- For example : Consider a data set {11,13,15,17,19}.
- To find the extreme : Find the smallest value in the data set and also find the largest value in the data set.
- Therefore, the extreme values are 11 and 19.

To solve the question, the both equations should have a positive value and a negative value with same number. Then one variable can be eliminated.
To eliminate X term first, we should multiply the first equation by 2 and second one by 3.
Then,
6X - 12Y = -30
-6X + 15Y = 70
Or
To eliminate Y term first, we should multiply the first equation by 5 and second one by 6.
Then,
15X - 30Y = -75
-12X + 30Y = 84
According to the choices given 'A' is the correct answer.
Answer:
14
Step-by-step explanation:
Tan = opposite / adjacent = 1.7 / 6.7
tan N= 1.7 / 6.7
N = 14.237 = 14
Answer:
23040 bats
Step-by-step explanation:
Let N(t) be the number of bats at time t
We know that exponential function
According to question
Where t (in years)
Substitute t=2 and N(2)=180
...(1)
Substitute t=5 and N(5)=1440
...(2)
Equation (1) divided by equation (2)
By using the property
Substitute the values of b in equation (1)
Substitute t=9
Hence, after 9 years the expected bats in the colony=23040 bats
