A balloon archway has been ordered for decorating the high school gym for a 1950's
style prom. The archway will contain 417 balloons, each holding 1.1 liters of helium.
Each balloon has a mass of 0.027 grams when empty, and all the string and fixings
that hold the balloons together total another 36 grams. If helium has a density of
0.1785 grams per liter, what is the mass of the entire archway.

Step-by-step explanation:

Given :

p = -5

q = 4

Putting the value of p and q in equation pq - (p + q)

=> (-5)(4) - [(-5)+4]

=> -20 - [ -5+4 ]

=> -20 - [-1 ]

=> -20+1

=> -19

https://keisan.casio.com/exec/system/14059932387562

1) Use this online graphing calculator if you do not have on ^^

2) plug in data and choose "e-Exponential regression"

3) A= 88.4385965

    B= -0.532128051

4) Round A to the nearest integer and B to the nearest tenth

5) Use the formula given "y=Ae^ Bx"

6) Leave the variables "e" and "x" as they are

A quadratic equation would best represent the data

i.e

-8x² + 93x - 56

A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.

In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.

The position of each point on the graph represents the values of both variables for that particular observation.

We have,
To determine the best equation to represent the data, we will first plot the points on a graphing calculator:

Day Snow Depth

1 47

2 29

3 20

4 10

5 7

6 5

7 1.5

Now,

Based on the scatter plot of the points, it appears that a quadratic equation would best represent the data.

Using the quadratic regression feature on the graphing calculator, we obtain the following equation:

Snow Depth = -8x² + 93x - 56

Rounding to the nearest integer, the final equation that best represents the data is:

Snow Depth = -8x² + 93x - 56

Thus,

A quadratic equation would best represent the data

i.e

-8x² + 93x - 56

Answer:

about $8

Step-by-step explanation:

Pizza at $2.95 can be rounded to $3.

Callie had two pieces of pizza, so $3 x 2 = $6.

Soda at $2.25 can be rounded to $2.

Two pieces of pizza $6 + Soda $2 = about $8

Explaination :

Let us assume the unknown two numbers as an variable. Here we are assuming it as a and b.

★ According to the question,

Sum of those assumed two numbers is 82.5.

a + b = 82.5

Also it is given that difference of both the two numbers is 12.9.

a - b = 12.9

From the given information we got two equations,

a + b = 82.5 (Equation No 1)

a - b = 12.9 (Equation No 2)

So we would solve them and get the value of a and b.

★ From Equation No 2 :

a = 12.9 + b

★ In Equation No 1 :

Substituting the value of a which we got above here,

(12.9 + b) + b = 82.5

12.9 + b + b = 82.5

12.9 + 2b = 82.5

2b = 82.5 - 12.9

2b = 69.6

b = 69.6 / 2

b = 34.8

★ Therefore,

★ Finding out value of a :

a = 12.9 + b

a = 12.9 + 34.8

a = 47.7

Minimize costs and maximize revenue best explains what the profit motive pushes producers to do. The correct option is B.

Revenue is defined as the money generated by normal business operations and is calculated by multiplying the average sales price by the number of items sold.

here, we have,

Revenue refers to the total earnings generated by a company through its core operations, such as product or service sales, property rents, recurring payments, interest on borrowings, and so on.

Net income is calculated by subtracting other costs and expenses from the total amount of money.

The profit motive drives producers to reduce production costs while increasing revenue in order to increase profits.

They can increase their financial gain and make their business more successful by doing so.

Thus, the correct option is B.

Answer: [tex]f^{-1} (x)=x^{2} -7[/tex]

Step-by-step explanation:

To find the inverse of a function replace f(x) with x and the original x with y

[tex]f(x)=\sqrt{x+7} \\x=\sqrt{y+7}[/tex]

Now we can solve for y

Square both sides so we can cancel out the root

[tex]x=\sqrt{y+7}\\x^{2} =\sqrt{y+7}^{2} \\x^{2} =y+7[/tex]

Now subtract 7 from both sides

[tex]x^{2} =y+7\\x^{2} -7=y+7-7\\x^{2} -7=y[/tex]

Now replace y with the inverse of f(x), [tex]f^{-1} (x)[/tex]

f⁻¹=x²+7

The simulation using random digits is an illustration of sample space and probability

From the question, we understand that the simulation is to determine the probability that she picks at least one green marble in her next two picks.

One of the ways this can be done is as follows:

The above ensures that the probability of picking a green marble in each selection is 0.5 and the probability of not picking a green marble in each selection is also 0.5 i.e. the experiment is fair

Next, is to run a simulation of 10 trials.

Take for instance, the result of the simulation is as follows:

00 65 36 48 55

19 34 87 13 90

The number of outcomes that has at least one of digits 0 - 4 represents the required outcome i.e. picking at least one green marble

From the simulation result, the number of outcomes is

At least 1 green marble = 7

Number of trials = 10

So, the probability of picking at least a green marble is:

P = 7/10

P = 70%

Note that there are several other ways the simulation can be done; this is just one of them
