Answer:
the x-coordinates of the intersection point of the lines y = 3x + 5 and y = 2x – 7
Step-by-step explanation:
When you set two equations or functions equal to each other that is saying you want to know when the graphs intersect. So the y and x intercept don't matter, unless you combined the terms like this.
3x + 5 = 2x – 7
x + 12 = 0 then that terms x intercept woudl be the x coordinate of the intersection of the other two terms. But remember, this is onlyif you combines the two functions.
Of your options you just want the ones dealing with the intersection point. And of those two we are plugging in x, so we want the x coordinate.
Answer:
a. 8.66 minutes
Step-by-step explanation:
Since the flight times are uniformly distributed, the standard deviation can be calculated as follows:
Where '<em>b' </em>is the maximum flight time (150 minutes) and '<em>a' </em>is the minimum flight time (120 minutes):
The distribution's standard deviation is 8.66 minutes.
True I’m pretty sure: Climate can change without studying weather patterns, you don’t need to study them for climate to be established. If i’m wrong sorry
