Answers

Answer 1

The correct option is (d) i.e; MD = 3 with s2 = 20 for the difference scores because it generates a repeated-measures study's population mean difference with the widest 90% confidence interval.

Given that,

Which of the following will result in the widest 90% confidence interval for the population mean difference for a repeated-measures research, provided the sample size is kept constant?

MD = 3 with s2 = 20 for the difference scores.

Therefore, the correct choice is MD = 3 with s2 = 20 for the difference scores because it produces the widest 90% confidence interval for the population mean difference for a repeated-measures study.

in general, high scores on the big five factor of ___are associated with less optimal life outcomes.

Answers

In general, high scores on the big five factor of Neuroticism are associated with less optimal life outcomes.

Neuroticism is one of the Big Five factors in the study of personality in psychology. Neuroticism is a personality trait characterized by sadness, moodiness, and emotional instability.

High neurotic people frequently experience mood swings, anxiety, impatience, and melancholy. People who score lower on this personality trait tend to be more emotionally stable and resilient. A person may strive to be a perfectionist during their everyday activities, and experience stress as a result of events that are beyond their control.

An individual with neuroticism may choose to concentrate on and dwell on the bad rather than the positive parts of a scenario. When individuals believe they have an advantage over others, they get envious of them and experience jealousy.

Answers

Here we want to find all the zeros of the function f(x) = 16*x^4 - 81.

What is function?

Function is a relation or expression involving one or more variables.

The zeros are:

x = 3/2

x = -3/2

x = (3/2)*i

x = (-3/2)*i

First, for a given function f(x), we define the zeros as the values of x such that:

f(x) = 0.

Then we must solve:

f(x) = 16*x^4 - 81 = 0

Solving this for x leads to:

16*x^4 = 81

x^4 =  81/16

x^2 = ±√(81/16) = 9/4

x = ±√±(9/4) = ±3/2 and ±(3/2)*i

So there are 4 zeros, and these are:

x = 3/2

x = -3/2

x = (3/2)*i

x = (-3/2)*i

Where the two complex zeros come from evaluating the second square root on

-9/4.

The value of cosθ₁ is -40/41 when angle θ₁ is located in quadrant II and sinθ₁=9/41.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that angle θ₁ is located in quadrant II and sinθ₁=9/41.

We need to find the value of cosθ₁.

We know that sinθ is opposite side/hypotenuse .

opposite side=9 and hypotenuse is 41.

By pythagoras theorem we find the adjacent side.

41²=9²+x²

41²-9²=x²

1681-81=x²

Taking square root on both sides

x=40

So adjacent side is 40.

cosθ₁=Adj/hyp

=40/41

Since it is in second quadrant the value of cosθ₁ will be -40/41.

Hence, angle θ₁ is located in quadrant II and sinθ₁=9/41 then value of cosθ₁ is -40/41.

Around the z-axis, cylinders take the forms of circles: x² + y² = r²

This cylinder will have the equation: x² + y² = 16

Its height is 3 so from z = -1 to z = 2

Answers

The interest owned and the maturity value of the loan is $217,300.

What is meant by interest?

Simple interest is calculated using the following formula. PRT/100 is the formula for simple interest (SI). In this case, the principal amount is P, the interest rate is R, and the interest period is T. The total sum that must be paid consists of the principal amount plus basic interest, or P + SI.

The interest rate for the loan is denoted by this proportion. When you deposit money in a high-yield savings account, for instance, a bank will give you interest. Simple interest examples include monthly-amortized auto loans and store installment loans; both have a dipping loan balance with each monthly payment as well as a dipping interest rate.

Principal amount=205,000

Given that the interest is 6%

=205000(6/100)

=12300

The maturity amount of loan is:

-5 = -20/7 + c

c = -15/7

Thus, the equation of the line is y = 5/7(x) -15/7

For parallel case:

When the two lines are parallel, they have equal slope i.e. m₁ = m₂

Line1(given):

7x+5y = 4  => y = (-7/5)x + 4/5

Thus,  m₁ = -7/5

m₂= -7/5

Line 2(unknown) with the point (−4,-5):

y = mx + c

-5 = -7/5(-4) + c

-5 = 28/5 + c

c = -53/5

Thus, equation of the line is y = -7/5(x) -53/5

Irlene invested $3,500 in a high-interest savings account for three years. For the first year, the interest rate was 9% compounded semi-annually. For the second year the rate became 5.25% with the same compounding period. For the third year the rate remained the same but it was compounded quarterly. What was the value of the investment at the end of the third year? For full marks your final answer should be rounded to the nearest cent.

Answers

Rounded to the nearest cent, the final value of Irlene's investment at the end of the third year is $4,431.78.

What is the easiest way to define interest rate?

A percentage of the principal, or the amount loaned, is what a lender charges a borrower as interest. The annual percentage rate, or APR, is the usual unit used to express the interest rate on a loan (APR).

To calculate the value of Irlene's investment at the end of the third year, you can use the formula for compound interest:

FV = PV * (1 + r/n)^(n*t)

Where:

FV is the future value of the investment (what you want to find)

PV is the present value of the investment (the initial amount, $3,500)

r is the annual interest rate (the rate for the third year is 5.25%)

n is the number of compounding periods per year (for the first year it was 2, for the second year it was 2, and for the third year it was 4)

t is the number of years the money is invested (3 years in this case)

Plugging the values into the formula, you get:

FV = $3,500 * (1 + 5.25%/2)^(23) * (1 + 5.25%/4)^(41)

= $3,500 * (1.0263)^6 * (1.0131)^4

= $3,500 * 1.1496 * 1.0534= $4,431.77

Arandomsampleof5weeksshowedthatacruise agency received the following number of weekly specials to the Caribbean: 20, 73, 75, 80, 82. a. Compute the mean, median, and mode. b. Which measure of central tendency best describes the data? c. Comment on the distribution of the data.

Answers

The mean is 66, the median is 75 and the mode is None.

The center or typical value of a dataset is represented by summary statistics known as measures of central tendency. These metrics, such as the mean, median, and mode, are examples. These statistics, often known as the central location of a distribution, show where the majority of values in a distribution fall.

Given,

No. of observations = 5

Mean = Total observations/ no. of observations = 20+73+75+80+82/5 = 66

Median = Middle most observation arranged from smallest to largest = 75

Mode = Observation which occurs at least twice = None

Mean describes the data the best because it takes the average of all the given data.

The distribution of the data set is scattered and the shape of the frequency graph is going upwards.

Answers

The graph of the system of inequalities y ≤ –0.75x  , y ≤ 3x – 2 is attached.

Actual solution of the inequalities in the graph is shown by common shaded region of both the inequalities below A(-0.533 , 0.4 ).

As shown in the question,

Given system of inequalities  are :

y ≤ –0.75x

y ≤ 3x – 2

Graph of the inequalities is attached.

For first inequality :

y ≤ –0.75x

When x = 0

y ≤ 0

when y =0 ⇒ x ≤ 0

For second inequality :

y ≤ 3x – 2

x = 0⇒ y ≤ -2

when y =0 ⇒x ≥ 2/3

Actual solution by converting into equalities

y = -0.75x

Substitute in second equation

-0.75x = 3x -2

⇒ 3.75x =2

⇒ x= 0.5333

⇒ y= -0.4

Graph below ( 0.533 , -0.4 ) represents the actual  solution.

Therefore, the actual solution of the attached graph of the inequalities is region below ( 0.533 , -0.4 ) common shaded region.

B. (-12) ÷ (-3) = -4
C. 12 ÷ (-3) = -4
D. (-12) ÷ 3 = -4

PLEASE ANSWER FAST!

Answers

The equation which represents the counters inside the rectangle is,

12 ÷ 3 = 4.

What is equation?

Two expressions joined by an equal sign form a mathematical statement known as an equation. An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.

In the given diagram there is a rectangle containing 4 counters.

Each counter containing 3 red balls.

So, the total number of red balls are 4 x 3 = 12.

From this the equation which represents the counters inside the rectangle is,

12 ÷ 3 = 4.

Hence, the equation which represents the counters inside the rectangle is, 12 ÷ 3 = 4.
