Hugo plans to buy packs of baseball cards until he gets the card of his favorite player, but he only has enough money to buy at most 444 packs. suppose that each pack has probability 0.20.20, point, 2 of containing the card hugo is hoping for. let the random variable xxx be the number of packs of cards hugo buys. here is the probability distribution for xxx:
Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
What is the discrete probability distribution?Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:
P(X = 1) = 0.2.P(X = 2) = 0.16.P(X = 3) = 0.128.P(X = 4) = 0.512.The probability that he buys fewer than 3 packs is given by:
P(X < 3) = P(X = 1) + P(X = 2).
Hence:
P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.
There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

which of the following most accurately explains an impact of burmese pythons on the everglades community in southern florida using the data provided?
An impact of Burmese pythons on the everglades community in Florida is that python predation has caused a trophic cascade that changed the mosquitoes' niche.
The impact of Burmese pythons.As a result of the predation by invasive Burmese pythons in the United States of America, the number of raccoons and white-tailed deer has decreased significantly in southern Florida.
Consequently, the mosquitoes' niche has been changed by a trophic cascade because they were forced to find alternative hosts such as cotton rats.
Based on the scientific records and information, we can deduce that an impact of Burmese pythons on the everglades community in southern Florida is that python predation has caused a trophic cascade that changed the mosquitoes' niche.

The kinetic energy will be "0.5 J". To understand the calculation, check below.
Kinetic EnergyAccording to the question,
Mass or object, m = 10 N or,
= 1 kg
Speed, v = 1 m/s
We know the formula,
→ Kinetic energy, K.E = [tex]\frac{1}{2}[/tex] mv²
By substituting the values, we get
= [tex]\frac{1}{2}[/tex] × 1 × (1)²
= [tex]\frac{1}{2}[/tex] × 1 × 1
= [tex]\frac{1}{2}[/tex]

Twelve identical point charges q are equally spaced around the circumference of a circle of radius r. the circle is centered at the origin. one of the twelve charges, which happens to be on the positive x axis, is now moved to the center of the circle.
There is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.
What is a line charge?A line charge refers to the charge that is allocated along a curve that is one dimensional in nature such as a circle.
In physics experiments, line charges are used in wire chambers. Wire chambers are used for high-energy physics experiments.
In summary, the charges are put at equal distances around the circumference of the circle in the example.
Because the charges at the opposing ends of the circle are similar, they exert an equal-magnitude repelling force in the opposite direction on the charge at the center of the circle, thus balancing out the forces.
This is why there is only one net force acting on the charge at the center of the circle that will only be subjected to a repulsive force from the charge is extant on the negative axis of x.
