Step-by-step explanation:
The vertical line test for a function passes when, if you draw a vertical line which intersects the graph, the line intersects the graph at ONLY ONE point.
It is quite clear that for all positive values of X, any vertical line will intersect the graph at 2 points, thereby failing the vertical line test for a function.
This is something you'll need a T table for, or a calculator that can compute critical T values. Either way, we have n = 10 as our sample size, so df = n-1 = 10-1 = 9 is the degrees of freedom.
If you use a table, look at the row that starts with df = 9. Then look at the column that is labeled "95% confidence"
I show an example below of what I mean.
In that diagram, the row and column mentioned intersect at 2.262 (which is approximate). This value then rounds to 2.26
<h3>Answer: 2.26</h3>
Answer:
The Probability found is:
P =
Step-by-step explanation:
Let x be the 10 cents coin.
Let y be the 25 cents coin.
We have to find all the possible outcomes
1) First coin = 10 cents, Second coin = 10 cents , so
(x,x) = 20
2) First coin = 10 cents, Second coin = 25 cents , so
(x,y) = 35
3) First coin = 25 cents, Second coin = 10 cents , so
(y,x) = 35
4) First coin = 25 cents, Second coin = 25 cents , so
(y,y) = 50
Find the probability of each outcome:
P(x,x) =
P(x,y) =
P(y,x) =
P(y,y) =
Add all the probabilities where sum is at least 35 i.e P(x,y) , P(y,x) , P(y,y)
P(x,y) + P(y,x) + P(y,y) =
