An arithmetic sequence starts with one number and you add the common difference to the previous term to get the current term
So...
f(x)=mx+b
m=common difference
b=starting point
f(11)=125=11m+b
-
f(1)=5=1m+b
--------
120=10m
Divide both sides by 10
12=m
Your common difference is 12.
Answer:
16/25
Step-by-step explanation:
Given
Number of green marbles = 9
Number of White marbles = 17
Total number of marbles = 26
Probability of picking a white marble = 17/26
When a white marble is picked without replacement,
Probability of picking another white marble after first picking a white marble
= 16/25
= 0.64
This is because the total number of marbles would have reduced from 26 to 25 and the number of white marbles from 17 to 16.
Answer:
y=2x/3 + 2
Step-by-step explanation:
3y= 2x +6
y=2x/3 + 2
complementary is 90 degrees. so, you combine like terms.
30−x2=37
