Answer:

Step-by-step explanation:

The number of jars of jam that has to be sold in order to break even is 106,250.

The minimum sales price is $24.36.

The monthly profit is $5,097.12.

The price per customer is $205.34.

The ROI is 106.68%.

Breakeven quantity = fixed cost / price – variable cost per unit

$42500 / (1.2 - 0.8) = 106,250

Minimum price = (fixed cost / breakeven sales) + variable cost

($562,795.00 / 61,755) + $15.25 = $24.36

Profit = revenue - total cost

Revenue = 443 x 28.99 = $12,842.57

Total cost = $3692 + (9.15 x 443) = $7,745.45

Profit = $12,842.57 - $7,745.45 = $5097.12

Price = (profit +  total cost) / number of customers

Total cost = $2,345 + (16.90 x 45) = $3,105.50

($6,135.00 - 3105.50) / 45 = $205.34

ROI = (profit / cost of the investment) x 100

Cost = fixed cost + variable cost

$5,750 + (0.80 x 4175) = $9090

Profit = total revenue - cost

(4.5 x 4175) - 9090 = $9,697.50

ROI = $9,697.50 /  $9090 = 106.68%

Answer:

3

Step-by-step explanation:

2x+3=9

You have to get rid of the 3 and the operation that is happening between the 2x and 3 is addition so you must do the opposite which is subtract .

2x+3-3=9-3

Cross out the 3's . What you do to one side do it to the other side .So subtract 3 from both sides .

2x÷2=6÷2

Now to get rid of the 2 you divide because the operation that is happening between the 2 and x is multiplication.And what u do to one side do it to the other . So

x= 3

No 108 is not a term of this sequence.

Step-by-step explanation:

3n+5 = 108

3n = 108 - 5

3n = 103

Divide both side with 3.

n = 103/3

n = 34.33

since n is not equal to 108 there it is not

Answer:

see below

Step-by-step explanation:

We can determine if 108 is a solution by setting 3n+5 =108

3n+5= 108

Subtract 5 from each side

3n+5-5=108-5

3n = 103

Divide by 3

3n/3 = 103/3

n = 103/3

This is not an integer so 108 is not a solutions

Step-by-step explanation:

Say that x = 1, since x can be any real number.

From part a -> x +2 = 3

and -> 10-x =9

then multiply the two results to get y -> 3x9 = 27

Now look at y=20+8x-x and plug in the same value for x where x = 1

you get -> y = 20 + 8(1) -(1) which simplifies out to 27. Therefore the equation is proven since they equal the same value.

Answer:

The information on the graph shows a positive nonlinear correlation and the weight of the dinosaur tends to increase according to its length.

A discrete graph is also known as a scatter plot that shows the discontinuous and the nonlinear data point on the graph.

From the graph, we can see the increasing weight of the Dinosaur size vertical y-axis and the increasing length of the feet on the horizontal x-axis.

Therefore, we can conclude that the data points show an increasing nonlinear weight on the graph as the length increases.

Perimeter of base: 40 :)

Slant height: 13

Area of base: 100

10^2 = 100

Surface area: 65000

(1/2)(100 x 13)

1/2(1300)

650

Have an amazing day!!

Please rate and mark brainliest!!!

Answer and Explanation:

1) The perimeter is the sum of the base's side lengths, so it is:

P = 10 ft * 4 = 40 ft

2) The height can be calculated using the Pythagorean Theorem. Take half of the base's side length for the short leg (5 ft) and the slant height (13 ft) for the hyptenuse:

5^2 + h^2 = 13^2

25 + h^2 = 169

h^2 = 144

h = 12 ft

3) To find the lateral area, take the area of one of the triangular faces of the pyramid and multiply it by 4, since there are 4 triangular faces:

LA = 4 * (1/2)(10 * 13)

= 4 * 65

= 260 ft

4) The area of the base is the product of its dimensions:

A(base) = 10 * 10

= 100 ft^2

5) Surface area is the sum of the lateral area and the base's area, so just plug in the values from problems 3 and 4:

SA = LA + A(base)

= 260 + 100

= 360 ft^2

Answer: Most likely it is A

Although it should be B, because a non linear function doesn't  have a rate of change. I already looked up this question many times so we know It's NOT C.

The best modeled by a nonlinear function with time as the independent variable is:

The value of a collectible baseball card that increases by a constant factor of 1.1, or by 10%, each year.

A nonlinear function is one that does not follow a straight line.

In this case, t

A) describes a linear function since the value of the gift card decreases by a fixed amount each month, resulting in a straight-line relationship.

B) describes a constant value, which is a special case of a linear function where there is no change over time.

C) The value of the collectible baseball card increases by a constant factor of 1.1 each year, which results in exponential growth. This behavior is best modeled by a nonlinear function.

D) describes a linear function since the value of the investment increases by a fixed amount each week, resulting in a straight-line relationship.

Yes, the given set can be the domain of an odd function if:

f(-3) = -f(3)

f(-2) = -f(2).

For a function y = f(x), we define the domain of the function as the set of possible values of x that we can input into the function.

And an odd function is a function such that:

f(-x) = -f(x).

In this case, we want to see if the set:

(-3,-2)U(2,3) = (-3, -2, 2, 3)

can be the domain.

It would only be the domain of an odd function if:

f(-3) = -f(3)

f(-2) = -f(2).

By definition of probability, the probability that a person surveyed was either male or had a cell phone is [tex]\frac{450}{600}[/tex]= 0.75

Probability is the greater or lesser possibility that a certain event will occur.

In other words, the probability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.

The union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".

The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:

P(A∪B)= P(A) + P(B) -P(A∩B)

The intersection of events, A ∩ B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.

In first place, let's define the following events:

The probability that a person surveyed was either male or had a cell phone is calculated as:

P(M∪C)= P(M) + P(C) -P(M∩C)

In this case, you know:

Replacing in the definition of probability:

P(M∪C)= [tex]\frac{220}{600}[/tex] + [tex]\frac{350}{600}[/tex] - [tex]\frac{120}{600}[/tex]

Solving:

P(M∪C)= [tex]\frac{220+350 -120}{600}[/tex]

P(M∪C)= [tex]\frac{450}{600}[/tex]= 0.75

Finally, the probability that a person surveyed was either male or had a cell phone is [tex]\frac{450}{600}[/tex]= 0.75
