I believe the answer is 0.1
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%
For this case what you should know is that the slope of the line can be calculated as:
Tan x = sin x / cos x
The lines x = 2 and x = 3 have an angle of 90 degrees with respect to the x axis:
Tan 90 = sin 90 / cos 90 = 1/0 = inf
Therefore, both lines have a rate of change that tends to infinity.
answer
Both lines have the same slope (infinity) Both are greater than m = -1
Answer:
your answer would be t=-1 or t=1
Step-by-step explanation:
-(2t-3) = 3t-2
Multiply
-2t+3 = 3t-2
Rearrange and Add up
-5t = -5
Divide both sides by 5
-t = -1
Multiply both sides by (-1)
t = 1
Which is the solution for the Negative Case
Solve the Positive Case
(2t-3) = 3t-2
Rearrange and Add up
-t = 1
Multiply both sides by (-1)
t = -1
have a great day!
Answer:
20
Step-by-step explanation:
First, rewrite the numbers in numerical order:
8, 10, 10, 15, 15, 20, 20, 20, 20, 25, 25, 25, 35
Then find the middle number: (note there's 6 numbers on each side of <u>20</u>)
<em>8 10 10 15 15 20 </em><u>20</u> <em>20 20 25 25 25 35</em>
Hope this helps!
