Answer:

Initiation fee= $50

Monthly charge= $25

Step-by-step explanation:

Giving the following information:

For 2 months it is $100 and for 6 months it is $200.

To calculate the fixed cost (initiation fee) and the variable cost per month, we will use the high-low method:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (200 - 100) / (6 - 2)

Variable cost per unit= $25

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 200 - (25*6)

Fixed costs= $50

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 100 - (25*2)

Fixed costs= $50

Initiation fee= $50

Monthly charge= $25

Answer:

<1 = 33

<2 = 90

<3 = 57

Step-by-step explanation:

<3 = 57 because of alternate interior angles

<2 + <3 + 33 = 180

<2 + 57 + 33 = 180

<2 + 90 = 180

<2 = 90

<1 + <2 + 57 = 180

<1 + 90 + 57 = 180

<1 + 147 = 180

<1 = 33

We need to find the probability that you are randomly assigned a General Practitioner or a doctor under the age of 45.

In order to find this probability, we need to find the number of doctors that are General Practitioner or under under the age of 45. Then, divide that number by he total of 17.

We know that 7 doctors are General Practitioners. And 2 of them are also under the age of 45.

Therefore, since ther are 4 doctors that are under the age of 45, there are 2 additional doctors, besided those 2 that follow in both categories, there are under the age of 45.

Summarizing, the number of doctors that are General Practitioner or a doctor under the age of 45 is:

Notice that this result can also be obtained by the formula:

Answer:

1/1/2

turn 150% into a decimal then turn that into a fraction

Answer:

3/2, or 1 and 1/2

Step-by-step explanation:

To convert a percentage to a fraction, take the number and divide it by 100, like so:

150/100

You must now simplify this fraction to its simplest form. Both the numerator and denominator are divisible by 50, so the simplified form of 150/100 is 3/2.

If you need this in mixed number form instead of improper fraction form, the answer is instead 1 and 1/2.

Answer:

Step-by-step explanation:

I hope this helped :)

The derivative \(\( y' \)\) of the implicit function \(\( y^2 - xy = -2 \)\) is 0, indicating a constant slope with no change in relation to \(\( x \)\).

To find \(\( y' \)\)for the implicit function \(\( y^2 - xy = -2 \)\), we can differentiate both sides of the equation with respect to \(\( x \)\) using the chain rule. Let's go step by step:

Differentiating \(\( y^2 \)\) with respect to \(\( x \)\) using the chain rule:

\(\[\frac{d}{dx}(y^2) = 2y \cdot \frac{dy}{dx}\]\)

Differentiating \(\( xy \)\) with respect to \(\( x \)\) using the product rule:

\(\[\frac{d}{dx}(xy) = x \cdot \frac{dy}{dx} + y \cdot \frac{dx}{dx} = x \cdot \frac{dy}{dx} + y\]\)

Differentiating the constant term (-2) with respect to \(\( x \)\) gives us zero since it's a constant.

So, the differentiation of the entire equation is:

\(\[2y \cdot \frac{dy}{dx} - (x \cdot \frac{dy}{dx} + y) = 0\]\)

Now, let's rearrange the terms:

\(\[(2y - y) \cdot \frac{dy}{dx} - x \cdot \frac{dy}{dx} = 0\]\)

Simplifying further:

\(\[y \cdot \frac{dy}{dx}\) \(- x \cdot \frac{dy}{dx} = 0\]\)

Factoring out:

\(\[(\frac{dy}{dx})(y - x) = 0 \]\)

Finally, solving:

\(\[\frac{dy}{dx} = \frac{0}{y - x} = 0\]\)

Therefore, the derivative \(\( y' \)\) of the given implicit function is 0.

Millimeters can be converted into centimeters by dividing the value by 10. The solution has been obtained by using the unit conversion.

What is unit conversion?

A unit conversion is used to express the same property in a different unit of measurement. For instance, you could use minutes instead of hours to represent time or feet instead of miles to indicate distance. It commonly occurs when measurements are provided in one system of units, such as feet, but are required in a different system, such as chains.

We are required to convert millimeters to centimeters.

We know that 1 centimeter = 10 millimeters

So, for converting millimeters to centimeters, we need to divide the value by 10.

Hence, millimeters can be converted into centimeters by dividing the value by 10.

\(9w+6d\)

Step-by-step explanation:

Given that:

Earnings per hour for washing cars = $9

Earnings per hour for walking dogs = $6

Number of hours for which car washing is done = \(w\)

Number of hours taken for walking dogs = \(d\)

Earnings for \(w\) hours for washing cars = Per hour earnings multiplied by number of hours = $9\(w\)

Earnings for \(d\) hours for walking dogs = Per hour earnings multiplied by number of hours = $6\(d\)

Total earnings by both = $(\(9w+6d\))

Now, given that

Number of hours spent washing cars = 5 hours

Number of hours spent walking dogs = 2 hours

Therefore, total earnings by both = 9 \(\times\) 5 + 6 \(\times\) 2 = $57

The expression that correctly shows the total of steps Eric needs to walk is y = -6,000x + 24,000.

The result would be (C) 27 if the above statement is accurate.

Three categories of integers exist: Zero (0) (0) Good integers (Natural numbers) Integer Negatives (Additive inverse of Natural Numbers).

As the two numbers are consecutive, we will refer to the smaller integer as "x" and the larger one as "x + 1".

In accordance with the issue, we have:

2x + (1/2)(x + 1) = 33

To eliminate the fraction, multiply everything by 2 and you obtain the following:

4x + x + 1 = 66

If we simplify, we get:

5x = 65

When we multiply both parts with 5, we get:

x = 13

Hence, 13 is the smaller number while 14 is the larger number.

Answer:

Each card will have a value of $15 when they equal after 600 days which also is 20 30-day periods.

Step-by-step explanation:

Card1: \(85 - \frac{3.50}{30} x\)

Card2: \(75 - \frac{3}{30} x\)

x is number of days

\(85 - \frac{3.50}{30} x = 75 - \frac{3}{30} x\)

2550 - 3.50x = 2250 - 3x

2550 - 0.50x = 2250

-0.50x = -300

x = 600 days

Card1: \(85 - \frac{3.50}{30} (600)\)

         85 - 70 = 15 dollars

Card2: \(75 - \frac{3}{30} (600)\)

         75 - 60 = 15 dollars

The value of each card will be when they have equal value is $15.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now, Let x be the number of time periods for which the gift card is not used, then

For the gift card $ 85 if it is not used for x periods, then the amount that will be lost is

85 - 3.50 x---------------------(1)

For the gift card $ 75 if it is not used for x periods, then the amount that will be lost is

75 - 3x---------------------- (2)

Now when both the amount lost is equal

85 - 3.50 x = 75 - 3x

solving the equation, we get

or, 3.50 x - 3x = 85 -75

or, 0.50 x = 10

or,  x = 20

Thus the value of gift cards will be equal for 20 ,30 day periods.

Now,the value of each card be when they have equal​ value

The two cards  will have equal value after 20, 30 day periods, this denotes that at this time, the value of each card will be equal.

Then

85 - 3.50 x = 75 - 3x

substituting  x = 20, we get

85 - 3.50*20 = 75 - 3*20

85 - 70  = 75 - 60

15  = 15

So, when they have equal​ value, the value of each card will be $15.

Answer:

Step-by-step explanation:

The perimeter of a quarter circle can be calculated by adding the length of the arc and the two radii that make up the quarter circle.

The length of the arc of a quarter circle is given by (πr)/2, where r is the radius of the quarter circle and π is approximately 3.142 (as given in the question).

So, for a quarter circle with a radius of 7 cm, the length of the arc would be:

(πr)/2 = (3.142 x 7)/2 = 10.997 cm (rounded to 3 decimal places)

The two radii that make up the quarter circle are each equal to the radius of the quarter circle, so the total length of the two radii would be:

2r = 2 x 7 = 14 cm

Therefore, the perimeter of the quarter circle would be:

10.997 cm + 14 cm = 24.997 cm (rounded to 3 decimal places)

So the perimeter of the quarter circle is approximately 24.997 cm. The digits given by the calculator will depend on the specific calculator used.

Step-by-step explanation:

The predicted effect on test scores when  income increases from $1,000 to $3,000 is ( a. 7.36.)

To find the predicted effect on test scores when income increases from $1,000 to $3,000, to substitute the values into the quadratic regression model and calculate the difference in test scores.

Given the quadratic regression model:

TestScore = 607.3 + 3.85Income - 0.0423Income^2

Let's calculate the test scores at income values of $1,000 and $3,000:

For income = $1,000 (1 in thousands):

TestScore1 = 607.3 + 3.85(1) - 0.0423(1)^2

= 607.3 + 3.85 - 0.0423

≈ 611.108

For income = $3,000 (3 in thousands):

TestScore2 = 607.3 + 3.85(3) - 0.0423(3)^2

= 607.3 + 11.55 - 0.3819

≈ 618.468

The predicted effect on test scores is the difference between TestScore2 and TestScore1:

Effect = TestScore2 - TestScore1

= 618.468 - 611.108
