The 1st graph has vertex in (-3, -3) which can be translated into
Horizontal shift left 3
Vertical shift down 3
Other than that, the graph shows y=x^2 so it wasn't compressed or stretched
The 2nd graph has vertex in (0, 0) which mean there is no vertical and horizontal shift. But the graph is facing down and it was slimmer than y=x^2 graph. When x=1, the result is y=3 which was 3 times more than it supposed to be.
The graph must be:
Reflection across x-axis
Vertical stretch of 3
The 3rd graph has vertex in (3, -3) which can be translated into
Horizontal shift right 3
Vertical shift down 3
Same as the 1st graph, the 3rd graph shows y=x^2 so it wasn't compressed or stretched.
Answer: 150m
Step-by-step explanation:
If mr A beats mr B by 70
and mr B beats Mr C by 80
you add up the 2 values and get 150
Given the mean of 4 years
Standard Deviation of 0.8 years
We are looking for the probability of that CD for 3 years.
P = (probability of the CD - mean) / standard deviation
P = (4 - 3) / 0.8
P = 1.25
So the probability is 1.25
