Now, imagine that port chester decides to crack down on motorists who park illegally by increasing the number of officers issuing parking tickets (thus, raising the probability of a ticket). If the cost of a ticket is $100, and the opportunity cost for the average driver of searching for parking is $25, which of the following probabilities would make the average person stop parking illegally? assume that people will not park illegally if the expected value of doing so is negative. Check all that apply
Assuming that people will not park illegally if the expected value of doing so is negative, the probability that a person could stop illegally parking would be 26% and 31%.
How to find the expected value?It is necessary to carry out the calculation, which is given by the following formula:
Expected value = P(x) × nApplying the values in the formula, we find the values:
= -(100 x 26%) + 25 = -(100 x 31%) + 25= -1$ = -$6Therefore, the 26% and 31% probabilities are the negative probabilities.
This is an incomplete question, and the other alternatives are:
A. 26%
B. 31%

Which of the following is true about the base b of a logarithmic function? b > 0 and b = 1 b > 0 and b < 0 and b < 0 and b = 1
The statement which is true of the base, b of a logarithmic function is; b > 0 and b = 1.
Base of a Logarithmic FunctionWhen the base of a logarithmic function is set to a negative number, it follows that;
Such logarithmic function wouldn't give us any real solutions! So the base CANNOT be negative. Putting together all 3 conclusions, we can say that the base of a logarithm can only be positive numbers greater than 1.

You push an object initially at rest across a frictionless floor
t = t₀ / 2
Explanation:
In this exercise we must use Newton's second law
F = m a
a = F / m
now we can use kinematics
as in object part of rest (v₀ = 0)
v =a t₀
t₀ = v / a
these results are with the first experiment
now repeat the experiment, but F = 2F₀
a = 2F₀ / m = 2 a₀
v = 2 a₀ t
t = v / 2a₀
t = t₀ / 2
The reaction 2mg(s)+o2(g)→2mgo(s) is highly spontaneous. A classmate calculates the entropy change for this reaction and obtains a large negative value for δs∘
Since there is a decrease in entropy owing to the solid product hence a large negative change in entropy is obtained.
What is entropy?The term entropy is the degree of disorder of a system. This question is incomplete but I will try to approach it in a general way. The equation of the reaction is; 2Mg(s) + O2(g)→2MgO(s).
We can see that in the reaction, the product of the process is a solid. Since a solid is rigidly arranged hence the entropy is largely decreased and a large negative change in entropy is obtained.

The method of graphing m(x) = log₆(x + 3) is; by translating each point of the graph of the function h(x) 3 units to the left.
How to Translate Functions?The function we are given is; h(x) = log₆x
From the given function, we notice that the function m(x) is the function h(x). However, it is shifted 3 units to the left.
Thus, it means that we could graph the function m(x) by translating each point of the graph of the function h(x) 3 units to the left.
Thus, the conclusion of this method of graphing m(x) = log₆(x + 3) is by translating each point of the graph of the function h(x) 3 units to the left.

The law of sine or the sine law expresses the ratio of the side length of a triangle to the sine of the opposite angle, which exists identical for all three sides. It stands also known as the sine rule.
What is an angle?
An angle exists the figure formed by two rays, named the sides of the angle, sharing a common endpoint, named the vertex of the angle. Angles formed by two rays lie in the plane that includes the rays. Angles exist also formed by the intersection of two planes. These exist named dihedral angles.
The law of sine or the sine law expresses the ratio of the side length of a triangle to the sine of the opposite angle, which exists identical for all three sides. It stands also known as the sine rule.

Answer:
ω = 13.33 rad/sExplanation:
Applying,
v = ωr......................... Equation 1
Where v = linear speed, ω = angular speed and r = radius.
Note that,
r = d/2................. Equation 2
Where d = diameter of the wheel.
Substitute equation 2 into equation 1
v = ωd/2............... Equation 3
make ω the subject of the equation
ω = 2v/d................ Equation 4
Given: v = 4 m/s, d = 60 cm = 0.6 m
Substitute these values into equation 4
ω = 2(4)/0.6
ω = 13.33 rad/s
