Answer:
Kiran's Aunt will be 32
Step-by-step explanation:
When Kiran was born her/his Aunt would be 17 as the problem says, so just add 15 to 17 to make 32; therefore Kiran's Aunt is 32 years old when Kiran is 15 years old. :)
A) Mean - add numbers of animals, and then divide by the number of students.
numbers of animals =1*20+2*11+3*18+4*10+5*3 +6*18 = 259
number of students = 20+20+11+18+10+3+18 = 100
mean=numbers of animals /number of students = 259 / 100=2.59
b) median
You can write 20 zeroes, 20 ones, 11 twos and so on. and the remove from left and right equal amount of number, when you get in the middle,it is going to be median
<u>20 "0", 20 "1", 11 "2"</u>, <u>18 "3", 10 "4", 5 "3", 18 "6"
</u> 51 place 51 place
From the left 20+20+11=51 places
18+5+10+18=51 places
We can see that no single middle number. In the middle is going to be two numbers 2 and 3, and divide them by 2.
(2+3)/2=2.5 median
3) (127/151)*100%≈ 84.11%
assuming the scale is by 1,
a) the slope is rise/run so it rises 3 units and moves 4 units right therefore the slope is 3/4
b) the y intercept is where the line crosses the y axis so by looking at the graph you can tell that the y int is 1
c) and the equation is made up of the slope and the y intercept: y= 3/4x + 1
The median of the following numbers is 14
Order the numbers from least to greatest
Since median means middle mark off a number on each side until there is one left. That will be your answer
If it is an even amount of numbers than take the middle two numbers and find the average (mean)
To do so add the numbers and divide by two
