if the slope is going down then its negative but if the line is going up its positive
Expected value equals sum of the product of each value and its possibility.
a.
1/2×75%+1/4×25%=0.4375
the expected value of grass growth for the day is 0.4375
b.
0.4375×31=13.5625
the expected value of grass growth for the month of july is 13.5625
On the x-axis, go left 2.75 units. from there, go up 4.2. whichever point is there is
your answer. that means the answer is A. P
Answer:
(x, y) ≈ (-5.89, 1.16)
Step-by-step explanation:
We assume the CD is still accelerating at the same rate at the end of the given time period. The angular position will be found from ...
θ(t) = θ₀ + (1/2)a·t²
Filling in the numbers given, we get
θ(3.51) = (10π/180) + (1/2)(2.49)(3.51²) = 15.51306 . . . radians
The x-y coordinates will be found from ...
(x, y) = radius·(cos(θ), sin(θ)) ≈ 6·(-0.981066, 0.193674)
(x, y) ≈ (-5.89, 1.16)
_____
For the trig functions, the calculator must be in radians mode, unless you have converted the angles to degrees.
1. 8/12 = 2/3 segment
2. 3/5 = 3/5 segment
