In a bag there are 3 red, 3 yellow, 4 green, and 6 blue marbles. What is the probability of p ( blue ) ?
Tan80=5.67
2tan70+tan10=5.67
So tan80=2tan70+tan10
Answer:
r=0.5 or 1/2
Step-by-step explanation:
if you multiply 0.5 to each Xs you can find out why r is 0.5
Answer:
The correct option is B.
Step-by-step explanation:
It is given that the correlation coefficient between two variables is -0.95.
Correlation coefficient between two variables is denotes by ρ. The value of ρ is leis between -1 to 1.
If 
, then it represent perfect negative correlation.
If 
, then it represent perfect positive correlation.
If 
, then it represent no relationship between the variables.
Since the -0.95 is near to the value -1, therefore we can say that there is a strong negative association between the variables. Option B is correct.
Answer:
Step-by-step explanation:
To find the inverse function, the first step we do is change f(x) to Y. So now, we have
y=2x+1
Now that we have this function, we simply flip x and y. When we do that, we get
x=2y+1
Now that we have this function, we just solve for Y. We do that by bring 1 to the other side by subtracting it from both sides, then dividing both sides by 2.
x-1=2y+1-1
x-1=2y
(x-1)/2=2y/2
(x-1)/2=y
So, our inverse function is:
y=(x-1)/2, or y=x/2 - 1/2
