You can make a proportion of 8/20 to 42/x and then simply cross multiply from there to solve for y

cuz thats wat it is cux i think so
Answers:
Row 1: No, No, No
Row 2: Yes, Yes, Yes
===============================
Explanation:
Use the vertical line test. If it is at all possible to draw a single vertical line through more than one point on the relation curve, then the relation is not a function. This is because a function is only possible when any x input leads to exactly one y output.
So that's why graphs 1,2,3 are not functions, while graphs 4,5,6 are functions.
Answer:

Step-by-step explanation:
In a two tailed test the probability of occurrence is the total area under the critical range of values on both the sides of the curve (negative side and positive side)
Thus, the probability values for a two tailed test as compared to a one tailed test is given by the under given relation -
\
Here 
Substituting the given value in above equation, we get -
probability values for a two tailed test
=
143/7 + (11-9)
143/7 + 2
143/7 + 14/7
143+14/7
157/7
Alternative form 22 3/7
