The program calculates the number of helium balloons needed to lift an object based on its weight by formulas for the volume of a sphere, the lifting capacity of helium, and the number of balloons required.

To calculate the number of helium balloons needed to lift an object, we can use the given equations. First, we find the volume of one balloon using the formula for the volume of a sphere: V = (3/4)πr^3, where r is the average radius of the balloons. Next, we determine how many kilograms one balloon can lift by multiplying the volume (V) by the conversion factor 9.958736 * 10^-7.

To find the number of balloons needed (N) to lift an object with weight M, we use the equation N = 1.0 + M / (V * 9.958736 * 10^-7). It is important to add 1.0 to account for the calculation of full balloons, rather than partial balloons.

In summary, the program will prompt the user to enter the average radius of the balloons (in cm) and the weight of the object being lifted (in kg). It will then calculate the volume of one balloon (V) in cm^3 using the sphere volume formula. The program will display V and the number of balloons needed (N) to lift the object. Finally, it will show the total volume of all the balloons by multiplying N and V.

The program utilizes the given formulas to determine the number of helium balloons required to lift a given object based on its weight, providing the necessary output for each step of the calculation.

After solving the equation, the number obtained is 4/3 and its reciprocal will be 3/4.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the data mentioned in the question,

Let the number be x.

Then the sum and reciprocal of the number is 25/12.

So, the equation will be,

x + 1/x = 25/12

(x² + 1)/x = 25/12

12x² + 12 = 25x or,

12x² - 25x + 12 = 0

Now, find the roots:

D = b² - 4ac

(-25)² - 4× 12× 12

D = 49

Then,

-(b ± √D)/2a

Therefore, the degree of the resulting polynomial is m + n when two polynomials of degree m and n are multiplied together.

What is polynomial?

A polynomial is a mathematical expression consisting of variables and coefficients, which involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and can be of different degrees, which is the highest power of the variable in the polynomial.

Here,

When two polynomials are multiplied, the degree of the resulting polynomial is the sum of the degrees of the original polynomials. In other words, if the degree of the first polynomial is m and the degree of the second polynomial is n, then the degree of their product is m + n.

This can be understood by looking at the product of two terms in each polynomial. Each term in the first polynomial will multiply each term in the second polynomial, so the degree of the resulting term will be the sum of the degrees of the two terms. Since each term in each polynomial has a degree equal to the degree of the polynomial itself, the degree of the resulting term will be the sum of the degrees of the two polynomials, which is m + n.

The probability of winning exactly 21 times is 0.14

Binomial probability refers to the probability of exactly 'x' successes on 'n' repeated trials in an experiment which has two possible outcomes (commonly called a binomial experiment).

Probability 'P' = ⁿCₓ (probability of 1st)ˣ x (1 - probability of 1st)ⁿ⁻ˣ

For example:

What is the probability of getting 6 heads, when you toss a coin 10 times?

In a coin-toss experiment, there are two outcomes: heads and tails. Assuming the coin is fair , the probability of getting a head is 1/2 or 0.5 .

The number of repeated trials: n=10

The number of success trials: x = 6

The probability of success on individual trial: p = 0.5

Use the formula for binomial probability.

¹⁰C₆ (0.5)⁶ x (1 - 0.5)¹⁰⁻⁶

Simplify.

The probability of winning exactly 21 times is 0.14 when the probability of winning the arcade game is 0.659.

We know that binomial probability is given by:

Probability (P) = ⁿCₓ (probability of 1st)ˣ x (1 - probability of 1st)ⁿ⁻ˣ

We are given that:

Probability of winning on an arcade game = P(A) = 0.659

So, the Probability of loosing on an arcade game will be = P'(A) = 1 - 0.659 = 0.341

Number of times the game is being played = 30

We have to find the Probability of winning exactly 21 times.

Here,

n = 30

x = 21

P(A) = 0.659

P'(A) = 0.341

Using the binomial probability formula, we get that:

Probability of winning exactly 21 times :

P(21 times) = ³⁰C₂₁ (0.659)²¹ x (0.341)⁷

P( 21 times ) = 0.14

The probability of randomly selecting the chair and the ranking member is 1/105 or approximately 0.0095.

There are 15 members of the Senate Committee on Homeland Security and Governmental Affairs, two of whom are selected to serve as the committee chair and ranking member. Each member is equally likely to be chosen for either of these positions.

To begin, we must first determine the total number of ways two members can be selected from a committee of 15. This is calculated using the combination formula:

nCr = (n!)/((r!)(n-r)!)where n = 15 and r = 2.

Thus,

nC2 = (15!)/((2!)(15-2)!)

nC2 = (15x14)/(2x1)nC2

= 105

Now we must determine the probability of selecting one member to be the committee chair and the other to be the ranking member.

This is calculated as follows: P = 1/105 or approximately 0.0095. Hence, the probability of randomly selecting the chair and ranking member is 1/105 or approximately 0.0095.

Answer:

A possible solution is she should by 6 bags of popcorn and 10 drinks

Step-by-step explanation:

The price of each bag of popcorn = $7.50

The price of each drink = $4.50

The amount Sarah has to spend = $90

The number of bags of popcorn and drinks Sarah must buy = 16 bags of popcorn and drinks

Let the number of bags of popcorn purchased be represented by x and the number of drinks purchased be represented by y

Therefore, we have;

x + y ≥ 16.....(1)

x × 7.5 + y × 4.5  ≤ 90

Which gives;

7.5·x + 4.5·y ≤ 90....(2)

Rewriting the inequalities as a function of y, gives;

From inequality (1), x + y ≥ 16, we have;

y = ≥ 16 - x

From inequality (2), 7.5·x + 4.5·y ≤ 90, we have;

7.5·x + 4.5·y ≤ 90

4.5·y ≤ 90 - 7.5·x

y ≤ 90/4.5 - 7.5/4.5·x

y ≤ 20 - 5/3·x

Please find attached, the plot of the inequalities

A possible solution is given as the value of x = 6, where y = 10

Therefore, she should by 6 bags of popcorn and 10 drinks.

The interquartile range (IQR) is a measure of the spread or variability of the middle 50 percent of the data.

The interquartile range (IQR) is a statistical measure that describes the spread or dispersion of the middle 50 percent of the data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of a dataset.

The quartiles divide a dataset into four equal parts, each representing 25 percent of the data. The first quartile (Q1) represents the lower boundary of the middle 50 percent, while the third quartile (Q3) represents the upper boundary of the middle 50 percent. The IQR captures the range of values within this middle range.

By focusing on the middle 50 percent of the data and excluding the extreme values, the interquartile range provides a measure of variability that is less affected by outliers or extreme values. It is commonly used in descriptive statistics and data analysis to understand the spread and distribution of a dataset, particularly when the data is not symmetrically distributed or contains outliers.
