What is Interquartile Range?

The interquartile range of a data set is the distance between the lower quartile and the upper quartile on a box plot.

Thus, a box plot that has a lower quartile of 3 and an interquartile range of 5 will have a distance of 5 from the lower quartile to the upper quartile.

The unit rate of discovery of the new species of marine animals are; 2000 per year.

What is unit rate?

There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.

We have been given about 4000 new species of marine animals were discovered in the last 2 years.

We need to find the unit rate of discovery.

Total = 4000 new species

Time = 2 year.

Unit rate = new species of marine animals/ time period

Unit rate = 4000/ 2

Unit rate = 2000/1

Therefore, the unit rate of discovery of the new species of marine animals are; 2000 per year.

A drilling crew dug to a height of 232 feet during their first day of drilling. On the second

bottom of the hole after the second day.
Answer using a mixed number and label your
answer.

Answers

The depth of the bottom of the hole after the second day is 425 feet using addition operation.

What is addition?

In math, addition is the process of adding two or more integers together. The terms addends and sum describe the input and output of the addition operation, respectively.

Given the depth on the first day is 232 feet.

Depth on the second day = 193 feet more than on the first day i.e. 193 feet + depth on the first day

This implies, depth on the second day = 193+232

=  425 feet

The hole's bottom will therefore be 425 feet deep after the second day.

Draw a right angle, aka 90 degree angle. Plot points A, B and D on it as shown below. Then add point C somewhere inside the rectangular region formed by this right angle. Lastly, connect a segment from B to C. This helps form angles ABC and CBD. Note how these smaller angles combine to a 90 degree angle.

Carolyn’s homeroom sold 207 magazine subscriptions. Of the magazine subscriptions sold, 28% were fashion magazines. About how many fashion magazine subscriptions were sold?

Answers

The number of fashion magazines subscription that were sold is approximately 58.

How to find the number of fashion magazine that was sold?

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100.

In other words, percentage is a fraction or a ratio in which the value of whole is always 100.

Therefore, Carolyn’s homeroom sold 207 magazine subscriptions. Of the magazine subscriptions sold, 28 percent were fashion magazines.

The number of fashion magazine subscriptions that were sold can be calculated as follows:

number of fashion magazine sold = 28% of 207

number of fashion magazine sold = 28 / 100 × 207

number of fashion magazine sold = 5796 / 100

number of fashion magazine sold = 57.96

Therefore, about 58 fashion magazines were sold.

B. Number of possible outcomes with red at least ounce in 4 spins: 175.

C. Number of possible outcomes with red at least ounce in 5 spins: 781.

How to obtain the number of outcomes?

The outcomes are obtained in two ways, as follows:

Combination -> Item a, as it is an arrangement with repetition, which is equivalent to combination.Fundamental Counting Theorem -> Items b and c.

Combination

The combination formula calculates the number of different combinations of x objects from a set of n elements, according to the equation presented as follows:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

From item a, there are 5 outcomes with 3 and 2 repetitions, hence the number of results is obtained as follows:

[tex]C_{5,3} = \frac{5!}{3!2!} = 10[/tex]

Fundamental Counting Theorem

It states that the number of outcomes of n independent trials is given by the multiplication of the number of outcomes for each trial.

For item b, we have that:

There are 4 spins.Each with 4 outcomes.

Hence the total number of outcomes, without considering the restriction is:

Total = 4^4 = 256.

With no red results, the number of outcomes is:

Total no red = 3^4 = 81.

Hence the number of outcomes with at least one red result, considering complementary events, is:

256 - 81 = 175.

Item c follows the same logic, only with 5 trials instead of four, hence:

4^5 - 3^5 = 781.

Assume that Chris is not a housekeeper for anyone else. Assume that Angel paid $2,250 in wages for the fourth quarter of 2021. The social security tax is $1,116, Medicare tax is $261 and FUTA tax is $42.

How to find the social security , Medicare and FUTA tax?

Social security  =12.4%

Medicare = 2.9%

FUTA = 0.6%

a. Social security tax

Yearly salary = $750 × 12 months

Yearly salary  = $9,000

Social security tax  = $9,000 ×12.4%

Social security tax = $1,116

b.  Medicare tax

Yearly salary =$750 × 12 months

Yearly salary = $9,000.00

Medicare tax = $9,000×2.9%

Medicare tax = $261

c. FUTA tax

Yearly salary = $750 × 12 months

Yearly salary = $9,000

The first $7,000 will be  subject to FUTA tax.

FUTA tax = $7,000 ×0.6%

FUTA tax = $42

The Solution of the equation y = C₁e⁴ˣ + C₂e⁻ˣ

Derivatives:

The derivative of a function is a function that indicates how quickly another function is changing. Differentiation is a term used to describe the process of finding a derivative. In an equation, it is shown as the dependent variable with respect to the independent variable. A value's derivative is a change in value relative to its input. The symbol for a derivative is f'(x).

           

Here we have

d²y/dx²-3(dy/dx) - 4y = 0

As we know (d/dx) = D

=> D²-3D - 4 = 0

=> D²- 4D + D - 4 = 0

=> D(D - 4) + (D - 4) = 0

=> (D - 4) (D + 1) = 0

=> (D - 4) = 0 and (D + 1) = 0

d)what is the maximum height the shell reaches and when will it occur? show your work.
E)when should the shell splash into the river? show your work
F)at what height was the shell when it was tossed off the cliff? show your work

Answers

a) She has three quadratic equations as one is the standard form, the other gives the roots, and the other gives the vertex.

b) If the distributive property is applied and the like terms combined, all the equations will have the same result.

c) The most helpful equations will be given for each point.

d) Maximum height of 64 feet after 1 second from h(t)=-16(t-1)^2+64.

e) The shell splashes into the river after a time of three seconds, from h(t)=-16(t+1)(t-3).

f) The shell was at a height of 48 feet when tossed into the river, from h(t)=-16t^2+32t+48.

What is the meaning of each quadratic function?

In standard format, the quadratic function is given as follows:

h(t) = -16t² + 32t + 48.

From this, the relevant information is the initial height from which the shell was tossed off the cliff, which is the c-coefficient of 48 feet.

The roots of the equation are given from the rule presented as follows:

h(t)=-16(t+1)(t-3).

Hence the shell splashes into the river at the positive root of h(t), that is:

t - 3 = 0 -> t = 3.

Expanding the equation, we have that it is equivalent to the first one, as:

-16(t + 1)(t - 3) = -16(t² - 2t - 3) = -16t² + 32t + 48.

The vertex-form quadratic equation is given as follows:

h(t) = -16(t - 1)² + 64.

Meaning that a maximum height of 64 feet was reached after one second.

Expanding the equation, we have that:

h(t) = -16(t - 1)² + 64 = -16(t² - 2t + 1) + 64 = -16t² + 32t - 16 + 64 = -16t² + 32t + 48.
