Answers

The z-test statistic is used to test the claim that the proportions of the two populations differ. A normal test statistic, the z-test statistic can also be used to measure the proportion of a single population.

Let's say that:

p1: Liberal voters' proportion of the population who smoked cannabis, p. 2:

Conservative voters' proportion of the population who smoked cannabis The null hypothesis is H 0:

The alternative hypothesis is H 0: p 1 = p 2.

p 1 p 2 P-value = 0.00001 The P-value is less than the significance level of 1%. The null hypothesis is rejected at the 1% significance level.

We can conclude that conservative voters had a lower percentage of voters who regularly smoked cannabis.

What is theory trying?

Two distinct hypotheses are tested by all analysts using a random population sample: the alternative hypothesis and the null hypothesis.

The value of the function G(-5 + h) - G(-5) in the simplest form -5h.

What is function?

Function is a combination of different types of variable and constants in which for the different values of x the value of function y is unique.

The given function is,

G(t) = 9 - 5t            (1)

To find the value of expression G(-5 + h) - G(-5),

First, find the value of G(-5 +h) by substituting t = -5+h in equation (1),

G(-5 + h) = 9 - 5(-5 + h)

               = 9 +25 -5h

               = 34 - 5h

The value of G(-5)

G(-5) = 9 - 5(-5)

        = 9 + 25

Does meditation cure insomnia? Researchers randomly divided 400 people into two equal-sized groups. One group meditated daily for 30 minutes, the other group attended a 2-hour information session on insomnia.
At the beginning of the study, the average difference between the number of minutes slept between the two groups was about 0. After the study, the average difference was about 32 minutes, and the meditation group had a higher average number of minutes slept.
To test whether an average difference of 32 minutes could be attributed to chance, a statistics student decided to conduct a randomization test. She wrote the number of minutes slept by each subject in the study on an index card. She shuffled the cards together very well, and then dealt them into two equal-sized groups, representing those who meditated and those who attended the information session.

O The average difference between the two values on the two stacks of cards is expected to be about 0 minutes.
O If meditation is effective, the average difference between the values on the two stacks of cards is expected to be more than 32 minutes.

Answers

1.  The average difference between the two values on the two stacks of cards is expected to be about 0 minutes best describes the outcome of the randomization test.

This randomization test was conducted to test whether the average difference of 32 minutes between the two groups could be attributed to chance. The test essentially involved shuffling the index cards containing the minutes slept by each subject and then dealing them into two equal-sized groups.

This process allows for a fair comparison between the two groups and ensures that any differences in the average minutes slept are due to chance. Since the cards are shuffled randomly, the average difference between the two stacks of cards is expected to be about 0 minutes.

If meditation is effective, then the difference between the values on the two stacks of cards would be expected to be more than 32 minutes.

Find the equation perpendicular to y=-2x+10 through (10,7)

Answers

Answer:

y = [tex]\frac{1}{2}[/tex] x + 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 10 ← is in slope- intercept form

with slope m = - 2

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation of the perpendicular line

to find c substitute (10, 7 ) into the partial equation

7 = 5 + c ⇒ c = 7 - 5 = 2

(20points) Let A be a symmetric positive define matrix with Cholesky decomposition A = LLT = RTR. Prove that the lower triangular matrix L(or that the upper triangular matrix R) in the factorization is unique.

Answers

In the factorization, the bottom triangular matrix L is the only one.

What is Cholesky decomposition?

The exponent of a number indicates how many times it has been multiplied by itself.

Exponent-related issues can be solved using either exponent laws or exponent characteristics. When a number is repeated numerous times by itself, writing the product without the use of exponents becomes very difficult. Major exponentiation rules are also thought of as having these characteristics.

Given that A is a positively defined symmetric matrix with a Cholesky decomposition,

A = L[tex]L^{T}[/tex]  = [tex]R^{T} R[/tex]

Let A be our positive define symmetric matrix,

suppose A has Cholesky decomposition,

A = L₁L₂ = L₁L₂ , for L₁, L₂ lower triangular matrix with positive diagonal entries,

thus (A x ,x) = (Lx, Lx) = (Lx, Lx)

pick x = eₓ  the last coordinate vector,

then (Aₓ, x) = Axx = || L₁x||² = || L₂x||²

Given that L1, and L2 are lower triangular, which necessitates that their lower right entry be the same,

The Kth entry is currently the last row.

given by (L₁, eₓ, eₓ) = 1/√Axx (L₁eₓ, L₂eₓ) = 1/ Aₓ = (Aeₓ, eₓ)

so the last row of L₁, L₂ be the same,

we reduce our A to new (n - 1)x(n - 1) submatrix,

which will likewise be true, and then repeat the process to discover each row's unique value.

Thus, the inductive process shows that L1 = L2.

As a result, the factorization's bottom triangular matrix L is exclusive.

Time can be described in mathematics as an ongoing and continuous series of events that take place one after another, from the past through the present, and into the future. The duration of events or the gaps between them can be measured, compared, or even ordered using time.

Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.

Time is defined by physicists as the flow of events from the past through the present and into the future. In essence, a system is timeless if it is unchanging. When describing events that take place in three-dimensional space, time can be thought of as the fourth dimension of reality.

The doctor told her to take a dose of 4.8 ml every 12 hours for 7 days.

If Theresa took her first dose at 9:00 AM on Monday,

What is the area of the triangle with vertices at A(2, 2), B(4, 5) and C(7, 5)? Express your
answer as a decimal to the nearest tenth.

Answers

Answer:

Therefore, the area of the triangle with vertices at A(2, 2), B(4, 5), and C(7, 5) is approximately 4.5, to the nearest tenth.

Step-by-step explanation:

To find the area of a triangle with vertices at A(2, 2), B(4, 5), and C(7, 5), you can use the Shoelace Theorem.

The Shoelace Theorem states that the area of a polygon with vertices (x1, y1), (x2, y2), ..., (xn, yn) is given by the following formula:

A = 1/2 * |(x1y2 + x2y3 + ... + xn-1yn + xny1) - (y1x2 + y2x3 + ... + yn-1xn + ynx1)|

To apply the Shoelace Theorem to a triangle with vertices at A(2, 2), B(4, 5), and C(7, 5), you can plug in the coordinates of these vertices into the formula:

A = 1/2 * |(25 + 45 + 72) - (24 + 57 + 52)|

= 1/2 * |(10 + 20 + 14) - (8 + 35 + 10)|

= 1/2 * |44 - 53|

To start dividing 126 by 23, Miranda used the estimate 120÷20 = 6. How could you tell six is too high?

Answers

Answer:

  the product of 6 and 23 is more than 126

Step-by-step explanation:

You want to know how to tell that 6 is too high an estimate for the first digit of the quotient of 126 and 23.

Trial dividend

When the trial quotient value of 6 is multiplied by the actual divisor of 23, we are computing 6(20 +3) = 120 +18. This is more than 126, so the trial quotient value is too large.

__

Additional comment

Another way to tell is to consider the dual problem that 120/20 = 6 represents: 120/6 = 20. It is easy to see that 126/6 = 21, so we know that a divisor of 23 (larger than 21) will give a quotient less than 6.

What is logarithm?

Logarithm is a mathematical operation which is used to determine the exponential power of a number. It is the inverse operation of exponentiation. Logarithm is commonly used in calculus, algebra, and other areas of mathematics. It can also be used to solve problems involving exponents, roots, and powers. Logarithm is denoted by the symbol log, and is read as "log to the base". The base is the number which the logarithm is taken to. For example, log2 10 is the logarithm to the base 2 of 10. This is equivalent to saying "2 to the power of what equals 10?" The answer is that 2 raised to the power of 3 (2^3) would equal 10.

Given, log x / 2 + 3 [ log(x-1) - 2/9 log(x+1) ]

        = log √x + 3 log(x-1) - 2/3 log (x+1)            {∵ log x^a = a log x }

        = log √x + log (x-1)^3 - log (x+1)^2/3

        = log √x + log [(x-1)^3 / (x+1)^2/3]              {∵ log a - log b = log a/b }

        = log [√x × (x-1)^3 / (x+1)^2/3 ]

If four vertices of a regular octagon are chosen at random then the probability that the quadrilateral formed by them is a rectangle is
A.1/8
B.2/21

D.1/35

Answers

The correct answer is option D. 1/35. To count the number of rectangles that can be formed, we need to consider the two cases where the diagonals of the rectangle are parallel to the sides of the octagon, and where the diagonals are perpendicular to the sides of the octagon.

In the first case, there are four choices for which side the diagonals are parallel to, and once that side is chosen, there are two choices for which pair of vertices lie on that side. Therefore, there are $4 \cdot 2 = 8$ rectangles of this type.

In the second case, there are four choices for which vertex the diagonals intersect, and once that vertex is chosen, there are two choices for which pair of vertices lie on the same side of the intersection point as the chosen vertex. Therefore, there are $4 \cdot 2 = 8$ rectangles of this type.

Altogether, there are $8 + 8 = 16$ rectangles. Therefore, the probability that the quadrilateral formed by the four vertices is a rectangle is

$\frac{16}{70} = \frac{16}{{8 \choose 4}}

                               = \frac{1}{{8 \choose 4}/16}

                               = \frac{1}{{8 \choose 4}/2^4}

The following are binomial random variable,

A)A Roll a fair die 5 times and X = the number of rolls that land showing a "4", is a binomial random variable.

B) Roll 5 fair dice at once and let Z = the number of dice that land showing an even value (2, 4, or 6), is a binomial random variable.

C) Roll 5 fair dice at once and let Y = the number of dice that land showing a "4" , is a binomial random variable.

A random binomial variable should satisfy the following conditions:

1. The number of trials are defined or fixed.

2. Each trial is independent of others.

3. The probability of success is same in all trials.

4. There should be only two outcomes in each trial.

Lets we evaluate the options based on the above conditions:

(A) Rolling fair dice 5 times have 5 trials, each rolling is independent, probability of 4 is 1/6 in all cases and the dice will either land 4 or will not land 4. So, X will have values from 0 to 5, 0 when dice doesn't land 4 even once in 5 rolls and 5 when dice land 4 in all rolls. This variable satisfies the condition to be a random binomial variable. So, X is a random binomial variable.

(B)For rolling 5 dices at once, the number of trials is 1 and fixed and the outcomes are 0 dice with even number to all 5 dices with even number. If the dices are rolled multiple times each trial will be independent of each other and the probability of success will be same for each trial. So the variable Z is a random binomial variable as it satisfies all the conditions.

(C)For rolling 5 dices at once, the number of trials is 1 and fixed and the outcomes are 0 dice land with 4 to all 5 dices land with 4. If the dices are rolled multiple times each trial will be independent of each other and the probability of success will be same for each trial.

What is a mathematical function, equation and expression?          

Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function

Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators

Equation : A mathematical equation is used to equate two expressions.

Given are two circles intersecting at each others centers at D and E.

We can write the area of the common region as -

[A] = 4 x {(θ/180) x (πr²/2) - (1/2)r²sinθcosθ}

Now, we can write θ as -

cos(θ) = (3/6) = 1/2

θ = 60°

[A] = 4 x {(60/180) x (π(6)²/2) - (1/2)(6)²sin(60)cos(60)}

[A] = 4 x {(1/3 x 36π/2 - (1/2) x 36 x [tex]\sqrt{\frac{3}{2} }[/tex] x 1/2}

[A] = 4 x {6π - 9 [tex]\sqrt{\frac{3}{2} }[/tex] }

[A] = 24π + (-  9 [tex]\sqrt{\frac{3}{2} }[/tex])

So, on comparing, with the expression below -

aπ + b[tex]\sqrt{c}[/tex]

We get -

a = 24

b = - 9

c = 3/2

So, we get -

a + b + c

24 - 9 + 3/2

24 - 9 + 1.5

24 - 7.5

16.5

Therefore, the expression of (a + b + c) is equivalent to 16.5.

In a network of 39 computers, 4 have a copy of a particularly critical file to sustain an organization's regular operations. Suppose that 8 computers at random fail. What is the probability that all 4 computers with the critical file fail in this incident? (Round to four decimal places.)

Answers

The answer is 34 because 39 x 4 equals 156 - 8= 148 divided by 4 equals 34

Answer:

-6/6 or -1

Step-by-step explanation:

To find the equation of the line (or the slope, assuming that's what equation means, ) we need to write the formula Y1-Y2/X1-X2

So, we need to fill in the numbers, which gives us the fraction -6-0/-2-(-8)

When we solve for the numerator (-6-0), we get -6.

When we solve for the denominator (-2 - {-8}), we get 6.

So, we have -6/6, which, when simplified, is -1.

(If the problem is not asking for slope when it says equation, then sorry!)

Option A is correct!!!!!!!!

Five years ago, you acquired a 30-year loan of $130,750, charging 6.6% annual interest, compounded monthly, and requiring monthly payments. At this time, interest rates on 15-year loans have dropped to 2.1% APR, compounded monthly, and you wish to refinance what you still owe with a new loan at this new rate. (a) How much (in dollars) will you be refinancing? Round your answer to the nearest dollar. (b) How much (in dollars) will your new monthly payment be after refinancing? Round your answer to the nearest cent.

Five years ago, you acquired a 30-year loan of $130,750, charging 6.6% annual interest, compounded monthly,

a) You will be refinancing $122536.

b) New monthly payment be after refinancing is

$794.1858 or 79 418.58 cents.

We have given that

Initial loan amount = $ 130,750

Number of year of loan = 30 year

Nomber of month of loan "n" = 30x12= 360

Annual interest rate = 6.6%

monthly rate "r" = 6.6% /12 =

monthly payment on the loan is

PMT= loan× r / [1 - (1+r)⁻ⁿ]

= $ 130750 X 12/(1 - (1+ 6.6%/12)⁻³⁶⁰)

= $719,125/(1- (1+0.0055) ⁻³⁶⁰

= $835.046

Monthly payment, $835.046 on initial loan.

Now after 5 years refinishing is done . So, amount and remaining balance is for 30-5 = 25 years and 25×12 = 300 months . The present value of unpaid monthly payment is

= PMT× ( (1 - (1+r)⁻ⁿ)/r)

= $835.046( 1 - (1+6.6%/12)⁻³⁰⁰/ 6.6%/12]

= $835.046× 196.74179

= $122536

Hence, amount refinanced is $122536.

b) New monthly payment will be on loan =$122536

Annual rate = 2.1%

monthly rate, r' = 2.1%/12

Number of years for refinancing = 15 years

Number of months , n' = 15× 12 = 180

Using the formula new monthly payment is

PMT = new loan× r'/ [1 - (1+r')⁻ⁿ´ ]

= $122536× 2.1%/12[ 1 - (1+2.1%/12)⁻¹⁸⁰]

= $214.43826/0.2700104

= $794.1858

Hence, new monthly payment is $794.1858.
