Answer:

a.) the effect of one independent variable depends on the levels of the second variable

Step-by-step explanation:

In regression, an interaction effect comes to play whenever the effect that an independent variable has on a dependent variable changes, as regards to value(s) of other independent variables( one or more variables). The variables that give interaction effect as a result of interaction with each other is reffered to as "interacting variables" For instance, in a research whereby how "Male gender versus female gender" and their " dieting B and dieting D" influence their " weight loss" There would be interaction effect in a situation where by a " female gender" that operate on " diet B" shed more weight compare with " male gender" that operate on " diet B". It should be noted that two variables are said to interact when the effect of one independent variable depends on the levels of the second variable

Answer:

  5/4

Step-by-step explanation:

The relationship between the sec and csc functions is ...

  csc(A) = sec(A)/√(sec²(A) -1)

For the given value of sec(A), this is ...

  csc(A) = (5/3)/√((5/3)² -1) = (5/3)/√(16/9) = (5/3)/(4/3)

  csc(A) = 5/4

Answer:

At t = 9, Whitney's acceleration will be -0.2 miles per minute.

Step-by-step explanation:

Remember that the acceleration is the derivative of velocity.

Since we want to find Whitney's acceleration at t = 9 and we are given the velocity function, we can simply find the derivative of the point at t = 9. In other words, a(9) = v'(9).

For the interval (7, 11), we simply have a line. So Whitney's acceleration at t = 9 will be equivalent to the slope of that line.

We have the two points (7, 0.8) and (11, 0). So, the slope between them is:

[tex]\displaystyle m=\frac{0-0.8}{11-7}=\frac{-0.8}{4}=-\frac{1}{5}[/tex]

So, a(t) = v'(t) = -0.2 ∀t ∈ {t | 7 < t  < 11}. Then at t = 9, Whitney's acceleration will be -0.2 miles per minute.

Answer:

The Millers paddled 4,666 miles each day.  If they reduced their daily distance by half, extending their trip to twice as many days, the distance traveled by the Millers would have been the same.

Step-by-step explanation:

Given that the Miller family likes to paddle along the river, and they paddled the same distance each day throughout the course of three days, traveling a total of 14 miles, to determine how many miles did they travel each day the following calculation must be performed :

14/3 = X

4.666 = X

Thus, the Millers paddled 4,666 miles each day.

In turn, if the Millers went half their daily distance each day, but extend their trip to twice as many days, to determine how far would they travel, the following calculation must be performed:

4.666 / 2 x 6 = X

2.333 x 6 = 13.9999

Thus, the distance traveled by the Millers would have been the same.

The population of deer at time t=3 years is approximately 4128 deer.

An exponential function is a mathematical function of the form [tex]f(x) = a^x[/tex], where a is a positive constant called the base, and x is the input variable. The exponent x represents the power to which the base a is raised.

The rate of growth of the deer population is given by the function [tex]R(t) = 2000e^{(0.231t)}[/tex], where t is the time in years since t=0.

To find the population at time t=3, we need to evaluate R(3) using the given function:

[tex]R(3) = 2000e^{(0.231\times 3)[/tex]

[tex]R(3) = 2000e^{0.693}[/tex]

R(3) ≈ 4127.72

Therefore, the population of deer at time t=3 years is approximately 4128 deer.

Answer:

The product of two rational numbers is rational.

So, multiplying two rationals is the same as multiplying two such fractions, which will result in another fraction of this same form since integers are closed under multiplication. Thus, multiplying two rational numbers produces another rational number.

Step-by-step explanation:

You can use elimination to get the value of y. Move numbers to one side and x and ys to the other side. To use elimination, multiply the first equation with 2. You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2

Answer:

$817.78

Step-by-step explanation:

To find the tax you must do the equation:

751.98 x 0.0875

(Btw, 0.0875 is decimal form of 8.75%. Always turn the percentage into a decimal before finding the tax or sale amount)

751.98 x 0.0875 = 65.80.

Now, add the sale tax amount and the original price:

751.98 + 65.80 = 817.78

Therefore, the answer is 817.78.

Answer:

Cost of the box of pencils = x = $4

Cost of the notebook = x+2 = 4+2 = $6

Cost of package of pens = 3x = 3(4) = $12

Step-by-step explanation:

Let the cost of the box of pencils = x

Cost of the notebook = 2 more than the pencils cost = x+2

Cost of package of pens = 3 times the pencils cost = 3x

The total was $22, so we can say:

(x)+(x+2)+(3x) = 22

5x=22-2

x=20/5

x=$4

Cost of the box of pencils = x = $4

Cost of the notebook = x+2 = 4+2 = $6

Cost of package of pens = 3x = 3(4) = $12

Answer:

Children=21 Adult=35

Step-by-step explanation:

[using c for children tickets and a for adult tickets]

56=c+a and 203=3c+4a [starting system of equations]

a=56-c ---> 203=3c+4(56-c) [plugging the first eq. into the second]

203=3c+224-4c [simplify]

-21=-c [simplify 2.0]

c=21 [simplify 3.0]

56=21+a [plugging back into org. eq.]

so a=35

Answer:

Assuming you want to know the volume,

volume = 2210.6 in³

Step-by-step explanation:

radius = diameter/2 = 8/2 = 4 in

area of base = πr² = (3.14)(4²) = 50.24 in²

volume of tube portion = base area x height = 50.24 x 40 = 2009.6 in³

cone volume = 1/3bh = 1/3(50.24)(12) = 200.96 in³

total volume = 2009.6 + 200.96 = 2210.56 in³

The compound interest implies that Juan owes $163.52 today

The given variables can be represented as:

The amount from a compound interest can be calculated using:

A = P(1 + r/n)^nt

Also from the question, we have

n = 12

This is so because the loan is compounded 12 times in a year as a result of being compounded monthly

So, we have

A = P(1 + r/n)^nt

A = 128 * (1 + (50%/12))^(0.5*12)

Evaluate

A = 163.52

Hence, the amount owed is $163.52
