The value of y when x= 2401 is -10
<h3>How to determine the value of x?</h3>An inverse variation is represented as:
Where k is the proportionality constant
When y = -70, x = 49
So, we have:
Take the square root of 49
Multiply through by 7
k = -490
Substitute k = -490 in
When x =2401, we have
Evaluate the square root
Divide
y = -10
Hence, the value of y when x= 2401 is -10

Answer: 0.923
Step-by-step explanation:
Let A be the event an Internet user posts photos that they have taken themselves, and B be the event an Internet user posts videos that they have taken themselves.
Pew Research Center finds that
P(A)=0.52 P(b)=0.26, and P(A or B)=0.54.
To find : P(A|B)
Since ,
i.e.
Now, using conditional probability formula ,
Hence, the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves = 0.923
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes, so we can find the slope:
Thus, the equation is of the form:
We substitute one of the points and find "b":
Finally, the equation is of the form:
