Answer: Mean = 27.33
Median = 27
Mode = 25 and 27
Step-by-step explanation:
1. Mean is the addition of all the numbers divided by how many numbers that are there.
Mean = (16 + 17 + 19 + 20 + 20 + 21 + 23 + 24 + 25 + 25 + 25 + 26 + 26 + 27 + 27 + 27 + 28 + 29 + 30 + 32 + 33 + 33 + 34 + 35 + 37 + 39 + 40) / 27
Mean = 738/27
Mean = 27.33
2. Median is the number in the middle in the ascending or descending other and this will be:
Median = 27/2 = 13.5 = 14th number = 27.
The median is 27.
3. Mode is the number that appears most and this will be 25 and 27 since they appear thrice which is the most times
ANSWER: -3/x^2
The negative exponent correlates to the x. In order for the exponent to be positive, it changes from the numerator to the denominator.
Well, $920 multiplied by .15 would equal 138 and
since 138 divided by 138 would equal 920. 15% of his income aka $138 would go towards his taxes.
Hope this helped!
have a great day! (:
Nice to see you again:)
You only need to convert the unit from nm to m.
So it will be:
5.2*10^4 * 10^-9 = 5.2*10^-5, which means 4 zeros before 52
Answer is C
Answer:
Solution:
When X=2
f(2)=1/2
= 1/2
When X= 1
f^-1(1)= 2*1
=2
When X=2
f^-1(2)=2*2
= 4
Step-by-step explanation:
I don't know if these are correct and if that last question is f^-1(2) or not.
