In this exercise we want to identify primitive elements (generators) of a multiplicative group since they play a big role in the DHKE and many other public-key schemes based on the DL problem. You are given a prime p = 4969 and the corresponding multiplicative group Z*_969. Determine how many generators exist in Z*_969. What is the probability of a randomly chosen element a Z*_969 being a generator? Determine the smallest generator a Z*_969 with a > 1000. What measures can be taken in order to simplify the search for generators for arbitrary groups Z*_p?
1. Number of generators of Z*4969 = 1584
2. Probability of a randomly chosen element a Z*_969 being a generator = [tex]\frac{1584}{4968}[/tex]
3. 1001 is the smallest generator
4. Number of generators
∅(n) = n [tex](1 - \frac{1}{p_{1} } )(1 - \frac{1}{p_{2} } ).........(1 - \frac{1}{p_{n} } )[/tex]
1. Every relative prime of 4968 offers a generation if a is the generation of Z.
4968 = 4 × 1242
= 4 × 3 × 414
= 4 × 3 × 2 ×207
= 4 × 3 × 2× 3× 69
= 4 × 3 × 2 × 3 × 3 ×23
[tex]= 2^{3} * 3^{3} * 23[/tex]
Number of generators ∅ (4968) = 4968[tex](1 - \frac{1}{2} )(1 - \frac{1}{3} )(1 - \frac{1}{23} )[/tex]
Number of generators of Z*4969 = 1584
2. When a Z*4969 value is set, it becomes a generation and belongs to one of the 1584 elements.
The probability that a element is selected from Z*4968 becomes a generation is
= favorable elememt / total element
= [tex]\frac{1584}{4968}[/tex]
= 0.3188
3. To find the smallest generator a Z*_969 with a > 1000.
a > 1000
Every relative prime of 4968 gives a generation of Z*4969
G C D (1001 4968) = 1
Hence, 1001 is the smallest generator
4. Number of generators
∅(n) = n [tex](1 - \frac{1}{p_{1} } )(1 - \frac{1}{p_{2} } ).........(1 - \frac{1}{p_{n} } )[/tex]

using traditional methods it takes 90 hours to receive an advanced driving license. a new training technique using computer aided instruction (cai) has been proposed. a researcher believes the new technique may lengthen training time and decides to perform a hypothesis test. after performing the test on 190 students, the researcher fails to reject the null hypothesis at a 0.02 level of significance.
The conclusion is that there is no sufficient evidence at the 0.02 level of significance that the new technique lengthens the training time.
Given,
The mean time taken to receive advanced driving license, through traditional methods [tex]\mu = 90[/tex] hours
The researcher believes the new technique may lengthen the training time
Researcher conducts hypothesis test of n = 190 students
The researcher fails to reject the null hypothesis at significance level, [tex]\alpha = 0.02[/tex]
Test hypothesis :-
[tex]H_0[/tex] :The mean time it takes for the new technique to receive an advanced driving license is 90 hours, i.e. [tex]\mu = 90[/tex].
[tex]H_a[/tex]: The mean time it takes for the new technique to receive an advanced driving license is greater than 90 hours, i.e. [tex]\mu > 90[/tex].
Failure to reject the null hypothesis means that our sample did not provide enough evidence to conclude that the effect exists. However, the lack of evidence does not prove that the effect does not exist.
As a result, the average time for the new technique to obtain an advanced driving licence is less than 90 hours.

Answer:
$40,601.92
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 1.5/100
r = 0.015 per year,
Then, solve the equation for P
P = I / ((1 + r/n)nt - 1)
P = 3150 / ((1 + 0.015/2)(2)(5) - 1)
P = 3150 / ((1 + 0.0075)(10) - 1)
P = $40,601.92
Summary:
The principal investment required to get a total interest of $3150 from compound interest at a rate of 1.5% per year compounded 2 times per year over 5 years is $40,601.92.

Noah went into a movie theater and bought 9 drinks and 4 candies, costing a total of $60. Nachelle went into the same movie theater and bought 10 drinks and 2 candies, costing a total of $57.50. Determine the price of each drink and the price of each candy.
Answer:
Drink: $5
Candy : $3.75
Step-by-step explanation:
Let d = the cost of a drink
Let c = the cost of a candy
9d + 4c = 60
10d + 2c = 57.50 ⇒ Mult. by -2 ⇒ -20d -4c = -115 Add this to the first equation
-20d - 4c = -115
9d + 4c = 60
-11d = -55 Divide both sides by -11
d = 5
A drink costs $5.00.
Plug in 5 for d in either of the two equations to solve for c
9d + 4c = 60
9(5) + 4x = 60
45 + 4c = 60 Subtract 45 from both sides
4c = 15 Divide both sides by 4
x = 3.75
A candy costs $3.75
Which statement is true about the functions f(x)=-15x^2+32 and g(x)=-17x^2+5x+32? a. f(x) and g(x) have the same zeros. b. f(x) has a higher maximum than g(x). c. f(x) and g(x) have the same y intercept. d. f(x) and g(x) are odd functions.
None of the options are valid because the specified functions are both parabolic.
Explain about the Functions?Functions represent the connection between two groups of values. For instance, if y=f(x), each value of x has a corresponding value in the set of y. The dependent variable is Y, and the independent variable is x.
An example of a rule is a function, which produces one output for a single input. Alex Federspiel is the picture's author. Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x. In mathematics and the sciences, functions are fundamental for constructing physical relationships.
Given functions in this case are
f(x)=-15x2+32
g(x)=-17x2+5x+32.
The functions' zeros are
x = 1.461, -1.233, and 1.527.

A completely randomized design is an appropriate design to use in this situation because There is no blocking variable, and incentive plans will be randomly assigned to the workers.
A completely randomized design (CRD) is the simplest design for comparative experiments because it employs only two basic experimental design principles: randomization and replication.
By randomization, we mean that the experimental units' run sequence is determined at random.
Treatments are assigned to experimental units or plots in a completely random manner in CRDs. CRD can be used for either single-factor or multifactor experiments.

how would you explain finding the slope to classmate
Answer/Step-by-step explanation:
Since the axes are labelled and there are nice points marked on the line, you can practically SEE the slope here without any calculating, just by counting. Start with a point and find the directions to the next point. To get from one point to the next, go UP2 and OVER3.
"UP2 and OVER3" is the slope 2/3. Double check that you get a slope that is positive because the line is going up to the right, it should have positive slope.
If the teacher is insisting that you use the slope formula, then name two of the points, such as (0, 4) and (3, 6). First subtract the y's, 6 - 4 is 2, put that on top of a fraction. Then subtract the x's, 3 - 0 is 3, put that on the bottom of a fraction. You get 2/3 again. Doesn't matter what points you use, since they are all on the same line it will come out the same.

What is null hypothesis?
A null hypothesis is an educated guess or a prediction of the expected outcome of a particular experiment. It is a statement that assumes there is no difference between two groups or no association between two variables. The null hypothesis is often the opposite of the alternative hypothesis, which is the prediction that the researcher is hoping to prove.
Example 1: In a study of the effectiveness of a new drug for treating depression, the null hypothesis would be that the drug has no effect on depression levels.

C) Domain: all real numbers x except x = ±2
E) f(x) → ∞ as x → -2⁻ and as x → 2⁺, f(x) → -∞ as x → -2⁺ and as x → 2⁻
Step-by-step explanation:
Given function:
[tex]f(x)=\dfrac{3x^2}{x^2-4}[/tex]
The domain of a function is the set of all possible input values (x-values).
A rational function is undefined when the denominator is equal to zero.
The denominator of the given function is zero when:
[tex]\implies x^2-4=0[/tex]
[tex]\implies x^2=4[/tex]
[tex]\implies \sqrt{x^2}=\sqrt{4}[/tex]
[tex]\implies x= \pm 2[/tex]
Therefore the domain of the function is:
all real numbers x except x = ±2The excluded x-values are x = -2 and x = 2.
To find the behaviour of the function near the excluded x-values, input values of x that are very near either side of excluded values:
[tex]x \rightarrow -2^-: \quad f(-2.001)=\dfrac{3(-2.001)^2}{(-2.001)^2-4}=3002.250...[/tex]
[tex]x \rightarrow -2^+: \quad f(-1.999)=\dfrac{3(-1.999)^2}{(-1.999)^2-4}=-2997,750...[/tex]
[tex]x \rightarrow 2^-: \quad f(1.999)=\dfrac{3(1.999)^2}{(1.999)^2-4}=-2997.750...[/tex]
[tex]x \rightarrow -2^+: \quad f(2.001)=\dfrac{3(2.001)^2}{(2.001)^2-4}=3002.250...[/tex]
Therefore, the behaviour of the function near the excluded x-values:

They paid $250 per month for daycare. They are filing MFJ. They can claim the credit for child and dependent care expenses. What is their eligible amount of work-related daycare expenses?
The eligible amount of work-related daycare expenses will be $2600
What is MFJ?Married filing jointly is a filing status for married couples, allowing them to file joint tax returns. When filing taxes under married filing jointly status, a married couple can record their respective incomes, deductions, credits, and exemptions on the same tax return.
Given here wages of the cliff are $16,228 and if the deb is $2,600
now the mfj is 35% hence cliffs credit is 35% × $16,228 = $5679.8
and daycare yearly expenses are = $250×12
= $3000
