Answer:
Hi there!
The answer for number 13 is 2.
I picked two coordinates: (1,1) and (2,3)
Then I used the (y1-y)/(x1-x) equation to get 2.
The answer for number 14 is 2.
I picked two coordinates: (1,0) and (2,2)
Then I used the (y1-y)/(x1-x) equation to get 2.
Answer:
yellow 9/25
yellow and green is 14/25
40
Try dividing 400 by ten you'll get 40 (or just remove a zero or decimal point to the left when dividing by 10)
B is correct the devotion is only 2 compared to 4.
A is wrong because variate A has higher trees then variate B
C is wrong because deviation for A is 4 compared to 2 ( opposite of B)
D is wrong because 4th one is 10 for A and 13 for B. 10 is not greater than 13
X^2+5x=2
you then solve by completing the square using the formula (b/2)^2 in order to create the new term. Solve for x by using this term to complete the square.
Your answer is then
x=-5/2+-√33/2
