Answer:
x = 1.5 , y = 3 + 2at.
Step-by-step explanation:
For the parabola = 4aX ,
General form will be
(X = a , Y = 2at) ,
Thus , for the parabola = 6(x +8)
Here , a = 1.5 and Y from the above equation should be substituted by y - 3 and X must be substituted by x + 8. After substitution of the same we can use the general equation formula for this parabola also.
Thus , general equation comes out to be :-
x + 8 = 1.5 , y - 3 = 2at
x = 1.5 , y = 3 + 2at.
Answer:
6.0520
Step-by-step explanation:
Given that:
Mean = 5.85
Standard deviation = 0.24
Let N denote the 80th percentile.
P(X < N) = 0.8
Using the Excel formula: = NORM.INV(0.8,5.85,0.24)
The 80th percentile for the diameters of mandarin oranges:
= 6.0520 (to 4 decimal place)
First simplify the expression into polynomial form,
Now factor into,
Which means the solutions are,
and then two complex solutions because determinant of the third factor ,
Hope this helps :)
