The average annual cumulative rainfall is 1  inch per month. During month of August average rain fall is greatest because slope in this month is maximum.

In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.

The graph does not represent cumulative rainfall as a function of day.

Because they have average all values for month Total cumulative rainfall is 12 inches.

Total period is 12 month

So, average annual cumulative rainfall is

12/12 =1 inch per month

Average rainfall in the month of December= (average cumulative rainfall in December - average cumulative rainfall in November)

= 12-11

= 1 inch

Therefore, during month of August average rain fall is greatest because slope in this month is maximum.

Given expression:

Simplify it in steps below:

Answer:

[tex] \sf \: 98h - 56k [/tex]

Step-by-step explanation:

Given expression,

→ 9(7h - 4k) + 10k - 5(6k - 7h)

Let's simplify the expression,

→ 9(7h - 4k) + 10k - 5(6k - 7h)

→ 63h - 36k + 10k - 30k + 35h

→ (63h + 35h) + (-36k + 10k - 30k)

→ (98h) + (-56k)

→ 98h - 56k

Hence, answer is 98h - 56k.

The domain is discrete and the range is continuous, which can be an accurate statement regarding the two terms.

The range of values that we are permitted to enter into our function is known as the domain of a function.

The x values for a function like f make up this set (x).

A function's range is the collection of values it can take as input.

After we enter an x value, the function outputs this sequence of values.

So, the parameters are as follows, taken from the query:

Downloaded Amount = $2.50

Added amount to each player = $1.50

Use x to indicate how many players there are.

The following representations are what we have.

Total amount = Amount to download + Amount to add each player * Number of players

Now, we obtain:

y = 2.50 + 1.50 * x

y = 2.50 + 1.5x

The number of players serves as the input to the aforementioned linear function.

The domain is discrete as a result.

The amount, though, can have decimal points

The range is continuous as a result.

Therefore, the domain is discrete and the range is continuous, which can be an accurate statement regarding the two terms.

Answer:  1⅗

Step-by-step explanation:  We can write 8 divided by 5 as 8/5.

As 8/5 is an improper fraction, when we divide 8 by 5, we get 1 as quotient and 3 as remainder.

To convert an improper fraction into a mixed fraction, we take quotient 1 as a whole part and in the fractional part remainder 1 as the numerator, and divisor 5 as the denominator.

The GCF of 5 and 1 is 1. So, divide both the numerator and denominator by the GCF to simplify and convert it to a mixed fraction.

Thus, 8 divided by 5 as a fraction in simplest form is 1⅗.

Least cost in the sales promotion is when (140, 70) i.e. Hats = 140 and pair of glasses = 70.

To determine if the data support the mixing of two potential sources or the fractionation of a single source, graphical approaches are frequently used.

To better interpret their data, researchers now employ a variety of graphical tools, including scatterplots, box plots, and histograms. Graphs are excellent for illustrating trends, patterns, and correlations between variables as well as for displaying and summarizing vast volumes of numerical data.

Value of cost at (140, 70) is 3 × 140+ 3 × 70

= $630

Consider any point on the feasible line, say (150, 60)

Cost = 3 × 150 + 3 × 60 =  $570

Cost is increasing towards the point (210, 0)

Thus, Least cost is when (140, 70) i.e. Hats = 140 and pair of glasses = 70.

First choice: 5x²+21x-20

Step-by-step explanation:

This is easy to answer if you realize that there is only one way an x² term can appear in the result and that is by the multiplication of 5x and x which results in 5x².

The only choice which has 5x² as a term is the first:  5x²+21x-20

However, it is important to know the FOIL method to multiply two terms together

FOIL stands for First Outer Inner Last and is a technique for multiplying two terms of the form (a+b) and (c+d)

In (a + b) (c + d),

First terms are a and c so their product is ac

Outer terms are a and d so their product is ad

Inner terms are b and c with product bc

Last terms are b and d with product bd

The result is the sum of all these terms

Let's take (5x - 4)(x + 5)
F: 5x·x = 5x²

O: 5x · 5 = 25x

I: -4 ·x = -4x

L: -4·5 = -20

Adding up these individual terms we get

5x² +25x - 4x - 20 = 5x²+21x-20

When the number of people is 16, the water lasts for 6 days, which is found using unitary method.

What is the unitary method?

The unitary method is a strategy for problem-solving that involves first determining the value of a single unit and then multiplying that value to determine the required value.

a) Let the amount of water present = L

Initially, this amount was considered for 12 people for 8 days.

For 12 people,

8 days = L

1 day = L/8

So the water required for one person for one day = (L/8) / 12 = L/96

But now 4 more people joined the trek,

So for 16 people, water used in one day = (L/96)*16 = L/6

Now the water will last for 6 days since,

                   (L/6 * 6) = L

b) The assumption that is made while solving the question is that the water required by each person is considered the same(L/96) even if the number of persons increases.

Therefore the water lasts for 6 days when the whole group consists of 16 people.

c. If 350 units were sold, the loss was Rs. 1500.

d. The graph of the functions are attached below.

The solutions are obtained using the profit function.

What is profit function?

A profit function is a mathematical relationship that represents the difference produced when the cost function is subtracted from the revenue function. The graph of a profit function shows the optimal combination of revenues and expenses to produce the maximum profit.

a. We are given cost of raw material as Rs. 15 and the fixed cost is Rs. 5000. The product is sold for Rs.25 per unit.

This means that R(x) = 25x

We know that TC= FC + VC(x)

So, TC = 5000 + 15x

Therefore, the profit function will be

⇒Profit = R(x) - TC

⇒Profit = 25x - 5000 - 15x

⇒Profit = 10x - 5000

b. For break even, the profit should be 0.

Therefore,

⇒10x - 5000 = 0

⇒10x = 5000

⇒x = 500

So, the break even will be at 500 units.

c. We are given x=350

Putting this value in profit function, we get

⇒Profit = 10(350) - 5000

⇒Profit = 3500 - 5000

⇒Profit = -1500

So, there is loss of Rs. 1500.

d. The red line represents the cost function and the blue line represents the revenue function.

The break even point is the point where the two lines are meeting.

The area below the break even is the loss area and above it is the profit area.

Answer:

vendor sold 90 sodas and 45 hot dogs

Step-by-step explanation:

Let x = number of sodas sold

Let y = number of hot dogs sold

We have x = 2y (1)
( The number of sodas sold was two times the number of hot dogs sold)

We also have x + y = 135 (2)

( sold a combined total of 135 sodas and hot dogs.)

Substituting x = 2y we get

2y + y = 135

3y = 135

y = 135/3

y = 45

Therefore x = 135 - 45

x = 90

Therefore vendor sold 90 sodas and 45 hot dogs

92 Square inches is the area of the shaded region shown below

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Given a rectangle, that has a length of 12 inches and 9-inch width

Since,

Area = length * width

Area of the given triangle = 12 * 9

Area of the given triangle = 108 square inch

There is also one square inside this rectangle of side 4 inch

Since the area of square = side * side

Thus in our case,

Area of square = 4 * 4 = 16 square inch

As we can see in the figure:

Area of shaded region  = complete area of rectangle - area of square

Area of shaded region  = 108 - 16

Area of shaded region  = 92 square inch

Step-by-step explanation:

Let's put this into an equation:

Note that 5 less than 4 means I take 5 AWAY from 4, not 5-4.

Most people would go about this straight across, doing 4-5, -1, and then times 7 which would be -7.
BUT if there are no parentheses around 4-5, we do 5 times 7 first.

Why? In PEMDAS or order of operations, you multiply before subtracting.

That means I do 5 times 7 first. That is 35.

Now I subtract 4-35. That is -31.
