<h3>Answer: Negative</h3>
Reason:
The template applies to any quadratic to graph out a parabola. The coefficient for the x^2 term is 'a', and it solely determines whether the parabola opens upward or downward.
If 'a' is negative, then the parabola opens downward. The way to remember this is that 'a' being negative forms a negative frown.
On the other hand if 'a' is positive, then it forms a positive smile, and the parabola opens upward.
In this case, the points are fairly close to a parabola opening downward. This means 'a' is negative and a < 0.
Answer:
The volume of the cylinder shown in the figure is 628 cube meters
Step-by-step explanation:
Given figure is about cylinder
The height of the cylinder = h = 8 meters
The radius of the base of cylinder = r = 5 meters
Now, let The volume of cylinder = V m³
So, The volume of cylinder is given as V = ×r²×h
where r is the radius of its base
And h is the height of cylinder
The value of = 3.14
So, V = × r² × h
Or, V = 3.14 × (5)² × 8
Or, V = 3.14 × 25 × 8
or, V = 628 m³
So, The volume of cylinder = V = 628 m³
Hence The volume of the cylinder shown in the figure is 628 cube meters Answer

Step-by-step explanation:
From the question we are told that
The sample size is n = 103
The sample mean of sag is
The sample mean of swells is
The standard deviation of sag is
The standard deviation of swells is
The number of swell for a randomly selected transformer is k = 100
The number of sag for a randomly selected transformer is c = 400
Generally the z-score for the number of swells is mathematically represented as
