Answer:
y = -3x + 2
Step-by-step explanation:
The linear equation is in the form
y = mx + b
where m is the slope and b is the y-intercept
the slope can be calculated using two points
Let us have; (-2,8) and (0,2)
The equation of the slope is ;
m = (y2-y1)/(x2-x1) = (2-8)/(0+2) = -6/2 = -3
So for the y-intercept, we select any of the points to substitute
Let us have (0,2)
Substitute this into;
y = -3x + b
2 = -3(0) + b
b = 2
So the equation is;
y = -3x + 2
Answer:there is multiple answers
Step-by-step explanation:
Ok I can’t actually show you the answer because I cannot do a hraph on the answer but to solve u just look at the table and where the no. Is time or distance. Time is x axis and distance is y axis and just move first the x and then go up on the y axis
Answer:
Step-by-step explanation: so to find slope it’s y2-y1/x2-x1
Slope is 1/6
Y = 1/6x + b
Plug in one set of points to find b Idek if u need to find it but
2 = 1/6(12) + b
2 = 6 + b
2-6 = -4
Y = 1/6x -4
Answer:
a) Attached
b) P=0.60
c) P=0.80
d) The expected flight time is E(t)=122.5
Step-by-step explanation:
The distribution is uniform between 1 hour and 50 minutes (110 min) and 135 min.
The height of the probability function will be:
Then the probability distribution can be defined as:
![f(t)=\frac{1}{25}=0.04 \,\,\,\,\\\\t\in[110,135]](https://tex.z-dn.net/?f=f%28t%29%3D%5Cfrac%7B1%7D%7B25%7D%3D0.04%20%5C%2C%5C%2C%5C%2C%5C%2C%5C%5C%5C%5Ct%5Cin%5B110%2C135%5D)
b) No more than 5 minutes late means the flight time is 125 or less.
The probability of having a flight time of 125 or less is P=0.60:
c) More than 10 minutes late means 130 minutes or more
The probability of having a flight time of 130 or more is P=0.80:
d) The expected flight time is E(t)=122.5
