(X, -Y) so the third question down, because it rotated 90° its only on quadrent moved and clockwise makes it go to the right!
d ( f o c) / dt = 9
( solution is attached below)
Answer:
B. 15.
Step-by-step explanation:
In order to get this answer, we just need to substitute the value of x in the formula and calculate the answer. Let's rewrite the expression with the substituions:
4((5)+5) ((5)+1) / ((5)+3) ((5)-3) = (40) (6) / (8) (2)= 240/16= 15.
Answer:
Option A.
Step-by-step explanation:
The given word is "mathematician".
Here, total number of letter is 13 and
Number of distinct letters = 8
We need to select 2 distinct letters from word "mathematician".
It means we need to select 2 letters from 8 distinct letters.
Total ways 
Therefore, the correct option is A.
Median: Put the list in order from least to greatest.
$20, $20, $23.50, $25, $26.50
$20, $23.50, $25
$23.50 is the median. I took one from each side until I had one left.
Mean: Get the sum of them all and then divide by the number of earnings ( in this case )
$25 + $26.50 = $51.50 $51.50 + $20 = $71.50 $71.50 + $23.50 = $95
$95 + $20 = $115 $115/5 = $23
$23 is the mean.
Mode: Is the one that finds the frequency or in lamen terms it is the number which appears most often.
There's no steps for finding the expect counting how many times that number appeared.
$20 is the mode.
