If a categorical independent variable contains 4 categories, then ________ dummy variables will be needed to uniquely represent these categories. a. 1 b. 2 c. 3 d. 4

Answers

If a categorical independent variable contains 4 categories, then four dummy variables will be needed to uniquely represent these categories. a. 1 b. 2 c. 3 d. 4

How many dummy variables are needed to represent the categorical variable?

We need 1 less dummy variable than outcomes for the categorical variable.

categorical variable has 2 outcomes

So, we need 2-1 = 1 dummy variable.

Note: If our categorical variable had 5 outcomes, we would need 5-1 = 4 dummy variables.

b. Write the multiple regression equation relating the dependent variable to the independent variables.

Note: Depending your your professor, this can be written one of the following ways...

yhat = a + b1 x1 + bx2

yhat = b0 + b1 x1 + b2 x2

yhat = beta0hat + beta1hat x1 + betahat2 x2

where x1 is the ratio variable

and x2 is the dummy variable

c. Interpret the meaning of the coefficients in the regression equation.

b0 = the predicted value of y when x1 and x2 both equal 0.

b1 = the change in y when x1 increases by 1 unit holding x2 constant.

b2 = the predicted difference in y between the two possible outcomes of the categorical variable holding x1 constant

Which is the polynomial function of lowest degree with rational real coefficients, a leading coefficient of 3 and roots and 2?.

Answers

On solving the given  question, we got that -  the polynomial function of lowest degree with rational real coefficients is [tex]= > P(x) = 3x^{2} - 21x + 30[/tex]

What is Polynomial Equation?

Polynomial equations are those created using variables, exponents, and coefficients. The higher exponent, known as the equation's degree, can have a variety of exponents. By factoring polynomials based on the degree and variables in the equation, we can solve them.

We are aware that the lowest degree polynomial function, denoted by p(x), has the following properties:

[tex]= > P(x) = c(x - a)(x - b)\\[/tex]

The leading coefficient is 3, the roots are 5, and the roots are 2, respectively.

Therefore, the lowest degree polynomial with the aforementioned characteristics is:

[tex]= > P(x) = 3(x - 5)(x - 2))\\= > P(x) = 3(x^{2} - 7x + 10)\\= > P(x) = 3x^{2} - 21x + 30\\[/tex]

If you divide the large triangle into two separate ones, with sides 7, 4 and 0.5y, you can use the pythagorean theorem to figure out 0.5y. So:

Now, we have only 5 position are left.

There are only 5 vowels and 10 integers digits.

So, we are assuming that the repetition is allowed because nothing else is mentioned.

So, total possible combinations are 1 x 1 x 15 x 15 x 15 x 15 x 15.

twice as many hours lifeguarding as he did at the local grocery store and earned $144.
How many hours did he work at each job?

Answers

Answer: He spent 3 hours as a cashier and 6 hours as a lifeguard

Step-by-step explanation:

First, you figure out his time as a cashier; 12($ per hour) x 3(hours working) = $36. Then, since it states he spent twice as many hours being a lifeguard, you double his hours when figuring out his time as a lifeguard; 18($ per hour) x 6(hours working) = $108. Add up both of your totals, $108 + $36 = $144.

Answers

Answer:

7.5

Step-by-step explanation:

W -- X -- Y ----- Z

We are given that :

Y is the midpoint of WZ meaning that WY = YZX is the midpoint of WY meaning that WX = XY WY = 5

Given this we want to find XZ

XZ consists of XY and YZ so we must find the length of the individual segments.

Finding YZ

Here, we know that YZ = WY as y is the midpoint of WZ. If WY = 5 then YZ also = 5

Finding XY

Given that WY = 5 and that X is a midpoint of WY we know that the segments WX and XY = WY and are congruent.
In other words we can say that 2XY = WY

==> WY = 5

2XY = 5

==> divide both sides by 2

XY = 2.5

Finding XZ

Again, XY + YZ = XZ

We have XY = 2.5 and YZ = 5

Hence, 2.5 + 5 = XZ

XZ = 7.5

Answer:

XZ = 7.5

Step-by-step explanation:

A drawing is sometimes very helpful.

Start by drawing a segment with endpoints W and Z.

   +--------------------------------------------+

   W                                                  Z

Y is the midpoint of WZ. Draw point Y in between W and Z and the same distance from both W and Z.

    +---------------------+--------------------+

   W                        Y                       Z

X is the midpoint of WY. Draw X between W and Y, and the same distance to W and Y.

   +----------+----------+--------------------+

   W          X           Y                       Z

Because of the midpoints, we know that:

WX = XY

WY = YZ

WY = 5

WX and XY are each half of WY, so WX = XY = 5/2 = 2.5

WY = YZ = 5

XZ = XY + YZ

XZ = 2.5 + 5

XZ = 7.5

the u.s. energy information administration claimed that u.s. residential customers used an average of 10,400 kilowatt hours (kwh) of electricity this year. a local power company believes that residents in their area use more electricity on average than eia's reported average. to test their claim, the company chooses a random sample of 163 of their customers and calculates that these customers used an average of 10,782kwh of electricity last year. assuming that the population standard deviation is 2768kwh, is there sufficient evidence to support the power company's claim at the 0.01 level of significance?

Answers

There is not sufficient evidence to support the power company's claim.

According to the information given in the question, we can frame the hypothesis as follows-

Null hypothesis ⇒ :  H = 10400

Alternate hypothesis ⇒ Ha:  > 10400

This is the right-tailed test.

Test statistic = z

[(x - μ)√n]/ σ

where x ⇒ sample mean = 10,782

σ ⇒ standard deviation = 2768

= (10782 - 10400)√163/ (2768)

= 382* 12.76/(2768)

= 1.76

⇒ Test statistic z = 1.76

Now, P( z > 1.76) = 1 - P( z < 1.76)

= 1 - 0.9608

= 0.0392

using z tables-

p-value = 0.0392

a = 0.01

we see that p-value > a

Thus, we fail to reject our null hypothesis.

Therefore, there is not sufficient evidence to support the  power company's claim.

One leg of a right triangle is 6 units long, and its hypotenuse is 12 units long. What is the length of the other leg? Round to the nearest whole number.

10 units
13 units
18 units
4 units

Answers

The length of the other leg of the right triangle, rounded to the nearest whole number, is 10 units.

To find the length of the other leg of the right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Let's denote the length of the other leg as x. Given that one leg is 6 units long and the hypotenuse is 12 units long, we can set up the equation:

6^2 + x^2 = 12^2

Simplifying this equation, we have:

36 + x^2 = 144

Subtracting 36 from both sides, we get:

x^2 = 108

Taking the square root of both sides, we find:

x = √108

Rounding this value to the nearest whole number, we have:

x ≈ 10.392

The length of the other leg of the right triangle, rounded to the nearest whole number, is 10 units.

The correct option is: 10 units.

The annual percentage rate (APR) for this loan is equal to 412.7%.

What is APR?

APR is an abbreviation for annual percentage rate and it can be defined as a measure of an amount of money based on a yearly rate of interest, which a borrower must pay on a loan or credit card.

Mathematically, the annual percentage rate (APR) of a loan can be calculated by using this formula:

APR = [((simple interest/principal)/n) × 365] × 100

Where:

n represents the number of days.

Note: n is equal to 14 days (2 weeks).

Substituting the given parameters into the formula, we have;
