Answers

A substantial interaction between age and educational status was discovered by a researcher who was creating a regression equation to predict income (y) in thousands of dollars from age (x1) and educational status (x2) (x3)

A dummy variable, educational status has the values 0 for no college degree and 1 for a college degree.

The regression formula is y = 0 + 1x1 + 2x2 + 3x1x2 where 0 is the intercept, 1 is the age regression coefficient, 2 is the educational status regression coefficient, and 3 is the regression coefficient for the interaction between age and educational status.

Let R be the relation defined on A as follows, and let A be the set of all statement forms in the three variables p, q, and r. S R T⇔ S and T have the same truth table for all S and T in A. substantiate the equivalence of R.

We have to demonstrate that it satisfies each of the properties you choose.

We know that,

By reflexive property,

S ≅ S  means that S has the same truth table as S.

T≅ T denotes that T and T have the same truth table.

By symmetric property,

S ≅T denotes that S and T share the same truth table.

At that time, T and S share the same truth table.

So, T ≅ S

By transitive property,

S≅T and T≅V and V≅W

S shares a truth table with S. Truth table between T and T W's truth table is the same for V and V.

S, T, V, and W all have the same truth table as a result.

S specifically has the same truth table as W.

The equivalent equation to the given logarithm is log₃9=2.

Define the term logarithmic equation?An equation using the logarithm of just an expression involving a variable is referred to as a logarithmic equation. Check to verify if you can write two aspects of the equation as powers of a similar number before attempting to solve an exponential equation.

A log function can be used to determine how much a given number must always be raised to reach the desired result.

aˣ = b

This can be written as;

logₐ b = c

Where an is the starting point from which the power will be raised,When power is increased, we want b to be the appropriate number,To obtain b, c must be increased to a power.

For the expression;

3² = 9

Given what we know about just the logarithm, the following is how we can represent the given equation:

Find f (5)
quick can someone answer meee

Answers

Answer:

f (5) = 4

Step-by-step explanation:

First we need to find f(x)

To do this we can find the gradient of the line then plug it into the formula for an equation of a line.

using the points on the line, (3,0) (0,-6)

gradient, m :

[tex] \frac{y1 - y2}{x1 - x2} [/tex]

[tex] \frac{0 - ( - 6)}{3 - 0} = \frac{6}{3} = 2[/tex]

therefore the gradient was found to be 2.

Equation of a line:

y - y1 = m( x - x1)

y - 0 = 2( x - 3)

y = 2x - 6

Therefore the function of the line was found to be:

f(x) = 2x -6

so to find f(5) we substitute 5 in the place of x:

f(5) = 2(5) - 6

f(5) = 10 - 6

f(5) = 4

a worn, poorly set-up machine is observed to produce components whose length x follows a normal distribution with mean 14 centimeters and standard deviation 3 centimeters. find the probability that the length of a component lies between 19 and 21 centimeters. round your answer to four decimal places.

Answers

The probability that the length of a component lies between 19 and 21 centimeters is 0.0376.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given:

Population mean, µ = 14

Population standard deviation, σ = 3

Probability that the length of a component lies between 19 and 21 centimeters

= P(19 <  X  < 21)

= P( (19 - 14) / 3 < (X - µ) / σ < (21 - 14) / 3)

= P(1.67 < z < 2.33)

= P(z < 2.33) - P(z < 1.67)

Using excel function:

= NORM.S.DIST(2.33,1) - NORM.S.DIST(1.67,1)

= 0.9901 - 0.9525

= 0.0376

Hence, the probability that the length of a component lies between 19 and 21 centimeters is 0.0376.

2) After how many months will the gym employee have made $19,500?

3) Write an equation to represent the constant of proportionality.

Answers

1. The amount that the employee make in 5 months will be $7500.

2. The number of months that the gym employee have made $19,500 is 13 months.

3. The equation to represent the constant of proportionality is C = 1500m

What is the constant of proportionality?

The constant of proportionality simply shows the ratio of two proportional values that possess a constant value.

Since after working for 3 months, he had earned $4,500. The amount per month will be:

= $4500 / 3

= $1500

The amount in 5 months will be:

= $1500 × 5

= $7500

The number of months that the gym employee have made $19,500 will be:

= $19500 / $1500

Answers

a)The 7-year growth factor for the amount on the loan is $4285.71.

b)  7-year percentage change for the amount is 6.25%.

c) 1-year growth factor for the amount $612.244.

d) 1-year percent change for the amount is 0.894%.

a)We know very well that growth factor is ratio of difference of principal amount and loan amount to the time taken, or

Growth factor=(Final loan amount-Initial loan amount)/Total time

=>Growth factor=(78,000-48,000)/7

=>Growth factor=30,000/7=$4285.71

b)To find the percentage change in amount, we need to use initial loan amount and the difference between two amounts, or

  percentage change=((78000-48000)/48000)×100

=>percentage change=[(30000)/48000)]×100

=>percentage change=300/48=6.25%

c)Now, we have already find the growth factor for 7 years, we need to find growth rate in 1 year. So, we use unitary method to find it

=>In 7 years growth factor is=$4285.71

   ∴In 1 years growth factor is=$4285.71/7=$612.244

d)In 7 years percentage change for the given amount is =6.25%

∴In 1 year percentage change for the given amount=6.25/7=0.894%

Answers

50 million people instead of 25 million people make up the population. The degree of assurance is reduced from 95% to 90%.

What is confidence interval?

A confidence interval in frequentist statistics is a range of estimates for an unknown parameter. A confidence interval is calculated at a specified degree of confidence; the most popular level is 95%, but other levels, such 90% or 99%, are occasionally used.

Because the standard error is reduced as sample size increases, confidence intervals are narrower.

Therefore, we may state that when the population standard deviation rises, the width of the confidence interval will also rise.

Hence, 50 million people instead of 25 million people make up the population. The degree of assurance is reduced from 95% to 90%.

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

Let the first point be P ( 0 , 3 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

The slope of the line we want to find will be the negative reciprocal of this slope, which is -4/3

Slope m = -4/3

Now , the equation of line is y - y₁ = m ( x - x₁ )

y - 3 = ( -4/3 ) ( x - 0 )
