The better strategy is to play the 'regular” defense. Because the probability of play in the 'regular” defense is more.
<h3>What is probability?</h3>
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
A football coach is trying to decide:
The coach reviews the outcomes of 100 games.
Regular defense Prevent defense Total
Win 41 32 73
Loss 9 18 27
Total 50 50 100
The probability of winning when playing regular defense will be
⇒ 41 / 50
⇒ 0.82
The probability of winning when playing prevent defense will be
⇒ 32 / 50
⇒ 0.64
Then the better strategy is to play the 'regular” defense.

Answer:
![(x+5)^{2}=-4(y+3)](https://tex.z-dn.net/?f=%28x%2B5%29%5E%7B2%7D%3D-4%28y%2B3%29)
Step-by-step explanation:
Given:
Focus point = (-5, -4)
Vertex point = (-5, -3)
We need to find the equation for the parabola.
Solution:
Since the x-coordinates of the vertex and focus are the same,
so this is a regular vertical parabola, where the x part is squared. Since the vertex is above the focus, this is a right-side down parabola and p is negative.
The vertex of this parabola is at (h, k) and the focus is at (h, k + p). So, directrix is y = k - p.
Substitute y = -4 and k = -3.
![-4 = -3+p](https://tex.z-dn.net/?f=-4%20%3D%20-3%2Bp)
![p=-4+3](https://tex.z-dn.net/?f=p%3D-4%2B3)
![p=-1](https://tex.z-dn.net/?f=p%3D-1)
So the standard form of the parabola is written as.
![(x-h)^{2}=4p(y-k)](https://tex.z-dn.net/?f=%28x-h%29%5E%7B2%7D%3D4p%28y-k%29)
Substitute vertex (h, k) = (-5, -3) and p = -1 in the above standard form of the parabola.
So the standard form of the parabola is written as.
![(x-(-5))^{2}=4(-1)(y-(-3))](https://tex.z-dn.net/?f=%28x-%28-5%29%29%5E%7B2%7D%3D4%28-1%29%28y-%28-3%29%29)
![(x+5)^{2}=-4(y+3)](https://tex.z-dn.net/?f=%28x%2B5%29%5E%7B2%7D%3D-4%28y%2B3%29)
Therefore, equation for the parabola with focus at (-5,-4) and vertex at (-5,-3)
![(x+5)^{2}=-4(y+3)](https://tex.z-dn.net/?f=%28x%2B5%29%5E%7B2%7D%3D-4%28y%2B3%29)
In parallelogram LMNO,
Since line LM || line QN, same side interior angles L and O will be supplementary angles.
i.e, angle L + angle O = 180
=> x+40 + 3x = 180
=> 3x + x + 40 = 180
=> 4x + 40 = 180
=> 4x = 180-40
=> x = 140/4
=> x = 35
now,
angle O = (3x)°
= (3 × 35)°
= 105°
The train is travelling at 80 miles per hour, this can be represented by 80mi/h
As the symbol suggests, you find the value of speed by dividing the amount of miles by the amount of hours.
Let S be speed, D be distance and T be time
we get S=D/T so we have also T=D/S
as such, the time to go 288 miles is simply:
