Answer:
- not a function
- an x-value is repeated
Step-by-step explanation:
A function maps each value of the independent variable to one value of the dependent variable. If an input maps to two or more different outputs, the relation is not a function.
On a graph, two or more different output values for the same input will show up as points vertically aligned with each other. That is, a vertical line will intersect the graph in more than one place. When that happens, we say the graph <em>does not pass the vertical line test, so is not a function.</em>
<em>___</em>
On the graph of these points, we show the vertical line that intersects two of the points of the given relation. The relation fails the vertical line test.
840 = 1×840=2×420 = 3×280 = 4×210 = 5×168 = 6×140 = 7×120 = 8×105
4220=1×4220 = 2×2110 = 4×1055 = 5×844
2840 = 1×2840 = 2×1420 = 4 × 710 = 5 × 568 = 8 × 355
Answer:
I believe the answer is 1 minus (StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction) (x 1)
Step-by-step explanation:
I believe that is the answer because when I used the point slope form and I used the points y-1= 2(x-1) When I reduced the answer I got minus 1 as the y intercept. I hope this helps.
Answer:
Step-by-step explanation:
the equation to this is
and slop-intercept form is
with m being the slope,
so,
Answer: Choice C) A and B must be independent
-------------------------------------------------------------------
In general,
P(A and B) = P(A)*P(B|A)
and
P(A and B) = P(B)*P(A|B)
The only time P(A) = P(A|B) and P(B) = P(B|A) are true is when A and B are independent. In other words, one event occurring does not alter the probability of the other event.
