Two football players with mass 80 kg and 120 kg run directly toward each other with speeds of 8 m/s and 10 m/s respectively. if they grab each other as they collide, the combined speed of the two players just after the collision would be
The combined speed after the collision is -2.8 m/s.
How to get the combined speed?
Here we must have conservation of momentum, where momentum is the product between mass and velocity.
At the beginning, one of the players has a mass of 80kg and a velocity of 8m/s, so its momentum is:
P₁ = 80kg*(8m/s) = 640 kg*m/s
The other player has a mass of 120 kg and runs in the opposite direction at a speed of -10m/s (the negative sign is because of the direction). So its momentum is:
P₂ = 120kg*(-10m/s) = -1200 kg*m/s
The initial total momentum is:
P = P₁ + P₂ = 640 kg*m/s + ( -1200 kg*m/s) = -560 kg*m/s
At the end, the move together as a mass of (80kg + 120kg) = 200kg with a velocity V.
Such that the final total momentum is equal to the initial total momentum.
So we must have:
200kg*V = -560 kg*m/s
V = (-560 kg*m/s)/200kg = -2.8 m/s.
The combined speed after the collision is -2.8 m/s.

Paul needs to randomly select one of his four children to go first in a board game. which simulation tools could he use in this situation?
The simulation tools that could be used by Paul in this situation is :
A spinner divided evenly into 12 sections, with three sections each of four different colors A standard deck of cards. Two coinsDescription of the simulator toolsA spinner divided into 12 sections with three sections each having four different colors can be used by calculating the prob of each subsection which simulates the probability of picking one of four children
Probability of each subsection
= number subsection / number of section
= 3 / 12 = 1/4
Two coins can also simulate the picking of one of four children
The outcome of the two coins = ( HH, HT, TT, TH )
Therefore the probability of picking a H or T
= 1 / 4
Also deck of 52 cards can also simulate the probability of picking one out of four children to go first in a board game.
Hence we can conclude that the simulator tools that can be used are A spinner divided evenly into 12 sections, with three sections each of four different colors A standard deck of cards. and Two coins.

Convert the following complex number into its polar representation -4i
The expression which represent the polar form of complex number -4i when converted into the polar form is 4(cos π+ isin π)
What is complex number?A complex number is the combination of real and imaginary number. In a complex number, real part and imaginary part of number is written together. For example,
a+bi
Here, (a) is the real part while (b) is the imaginary part.
The complex number which need to convert into its polar representation is,
n=-4i
It can be rewritten as,
n=0-4i
The radius r of the polar form is,
r²=0²+(-4)²
r²=0+16
r=4
The value of cos theta is,
tan θ=0/-4
θ=tan⁻¹(0)
θ=π
Thus, the polar form is,
z=rcos θ+(r sin θ)i
z=-4(cos π+ isin π)

Of 1000 students surveyed, 490 were boys and 320 had bicycles. of those who had bicycles, 130 were girls. what is the probability that a student surveyed was either a boy or had a bicycle?
By definition of probability, the probability that a student surveyed was either a boy or had a bicycle is 62%.
Definition of ProbabitityProbability is the greater or lesser possibility that a certain event will occur.
In other words, the probability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.
Union of eventsThe union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".
The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:
P(A∪B)= P(A) + P(B) -P(A∩B)
The intersection of events, A ∩ B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.
Events and probability in this caseIn first place, let's define the following events:
A: The event that a student surveyed was a boy.B: The event that a student surveyed had a bicycle.Then you know:
P(A)= [tex]\frac{490}{1000}[/tex]=0.49= 49%P(B)= [tex]\frac{320}{1000}[/tex]= 0.32= 32%P(A and B)= P(A∩B)= [tex]\frac{190}{1000}[/tex]= 0.19= 19% [320 students had bicycles. Of those who had bicycles, 130 were girls. Then, 190 were boys.]In this case, considering the definition of union of eventes, the probability that a student surveyed was either a boy or had a bicycle is calculated as:
P(A∪B)= P(A) + P(B) -P(A∩B)
P(A∪B)= 0.49 + 0.32 -0.19
P(A∪B)= 0.62= 62%
Then, the probability that a student surveyed was either a boy or had a bicycle is 62%.
