The number in question is 28.

To make solving this problem easier, we need to consider the number.

Let the number is ab.

So that,

4 × a = b

4a = b

We spread the numbers on the options.

28

(4 × 2 = 8) → True

32

(4 × 3 = 2) → False

15

(4 × 1 = 5) → False

25

(4 × 2 = 5) → False

We prove what number of 28 is when the digits is reversed to be greater than 54.

28 ⇄ 82

It is proved that the number 82 is greater than the number 54.

So, the number in question is 28.

A system of equations in standard form to model this scenario include the following:

2x + 10y = 74.

x + y = 17.

In order to write a system of linear equations that could be used to model the situation and determine the number of small boxes shipped and the number of large boxes shipped, we would assign variables to the number of small boxes that were shipped, the number of large boxes that were shipped respectively as follows:

Next, we would translate the word problem into system of linear equations as follows:

Since x small boxes weigh 2 pounds each and y large boxes weigh 10 pounds each and  all the boxes she ships is 74 pounds;

2x + 10y = 74.

Additionally, she is shipping 17 boxes altogether;

x + y = 17.

a must be the least upper bound of S because it satisfies both conditions: it is an upper bound of S, and any other upper bound b for S must be greater than or equal to a.

What is the difference between the least upper bound and upper bound?

An upper bound of a set S of real numbers is any real number that is greater or equal to all numbers in S. A lower bound is any which is less than or equal to all numbers in S. A least upper bound is an upper bound that is less than or equal to all upper bounds.

To prove that a is the least upper bound (LUB) of the set S, we need to show that a satisfies two conditions:

a is an upper bound of S, meaning that for every element x in S, x <= a.

If there is another upper bound b for S, then a <= b.

First, we already know that a is an upper bound of S because it is given that a is an upper bound of the set S.

Next, suppose there is another upper bound b for S such that b > a. Then, since the sequence xₙ converges to a, there exists a positive integer N such that for all n >= N, xₙ is arbitrarily close to a, meaning that |xₙ - a| < (b - a)/2. This means that xₙ < b for all n >= N, which contradicts the assumption that b is an upper bound of S, since xₙ is an element of S and xₙ < b.

Therefore, a must be the least upper bound of S because it satisfies both conditions: it is an upper bound of S, and any other upper bound b for S must be greater than or equal to a.

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

The value of f(-7) from the graoh is 1/128

Exponential function typically refers to the positive-valued function of a real variable, although it can be extended to complex numbers or generalized to other mathematical objects like matrices.

From the given graph, we need to determine then value f(-7). The function f(-7), is the equivalent value on the y-axis if the value of x is -7.

The standard exponential equation is y = ab^x

Using the coordinate points (0, 1) and (-2, 4), the resulting equations are:

1 = ab^0

4 = ab^-2

From equation 1, a = 1

4 = b^-2

b^2 = 1/4

b = 1/2

Step-by-step explanation:

We can find the rental cost for each movie and each video game by dividing the total cost by the number of movies and video games rented, respectively.

For the movies:

Rental cost for each movie = Total cost of movies rented / Number of movies rented

= $33 + $24 = $57

= $57 / 6 = $9.50 per movie

For the video games:

Rental cost for each video game = Total cost of video games rented / Number of video games rented

= $18 + $24 = $42

= $42 / 4 = $10.50 per video game.

Answer: To find the distance fallen after 1.6 seconds, we simply plug this value into the function and solve for h:

The amount of commission Yemi gets is, ₦51

Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".

Given that,

Yemi sold 100 books at ₦4.25 each,

So,

the total sales revenue is,

⇒ 100 x ₦4.25

⇒  ₦425

The publishing company gives a 12% commission on sales,

So, Yemi's commission would be,

⇒ 12/100 x ₦425

b ) 1445 cm far beyond its natural length will a force of 30 N keep the spring stretched.

A spring has a spring constant k,

It takes force kx to extend the spring's length.

A spring stretched length x has energy kx²/2.

Work of 3J gave the spring energy k(53-36)²/2.

Therefore,

3 = k(53-36)²/2

k = 6/289 N/cm

Work is needed to stretch the spring from 41 cm to 45 cm

At 41 cm the spring has energy k(41-36)²/2.

At 45 cm the spring has energy k(45-36)²/2.

The extra energy is given by,

(6/289)(45-36)²/2 - (6/289)(41-36)²/2

= (6/289) * 81/2 - (6/289) * 25/2

= 243/289 - 75/289

what is perimeter ?

An enclosed line that surrounds, distinguishes, or incorporates a two-dimensional contour or a three-dimensional length is referred to as a boundary. The edge of an ellipse or circle refers to its broadest area. The perimeter calculation has many useful properties. The rim of a form is its edge's radius. Understand how to determine the perimeter by adding the lengths of such sides of various forms. You can always measure the perimeter of a shape by multiplying its side lengths. The perimeter of an object is the space around it. At your house, any enclosed terrace is one illustration. The border of anything is the area encircling it. For a 50 feet x 50 feet yard, a 200 foot fence is required.

What is Poisson Distribution?

The Poisson distribution is a discrete probability function that means the variable can only take specific values in a given list of numbers, probably infinite. A Poisson distribution measures how many times an event is likely to occur within “x” period of time.

The mean of the Poisson distribution is given by λ.

The cumative distribution function is -

P(X = π) = (e^(-λ)λ^π) / π!, where π = 0,1,2,...

a) So, putting π = 1, λ = 7 in the above formula -

P(X = 1) = (e^(-7)7^1) / 1!

P(X = 1) = (0.000911 × 7) / 1

P(X = 1) = 0.006377

Therefore, the value is P(X = 1) = 0.006377.

b) P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)

P(X ≤ 2) = (e^(-7)7^0) / 0! + (e^(-7)7^1) / 1! + (e^(-7)7^2) / 2!

P(X ≤ 2) = 0.000911 + 0.006377 + 0.022319

P(X ≤ 2) = 0.0296075

Therefore, the value is P(X ≤ 2) = 0.0296075.

c) So, putting π = 4, λ = 7 in the above formula -

P(X = 4) = (e^(-7)7^4) / 4!

P(X = 4) = (0.000911 × 2401) / 24

P(X = 4) = 0.091137

Therefore, the value is P(X = 4) = 0.091137.

c) So, putting π = 8, λ = 7 in the above formula -

P(X = 8) = (e^(-7)7^8) / 8!

P(X = 8) = (0.000911 × 5764801) / 24

P(X = 8) = 0.130251

Therefore, the value is P(X = 8) = 0.130251.

Therefore , the solution of the given problem of test statistic comes out to be rounding to two decimal places, the z-score is -0.26.

The Z-statistic, which demonstrates that the ordinary ordinary neutral hypothesis is true, has been used as the statistic for anything resembling a Z-test. Let's say you run two separate X-y tests with a 0.05 level of significance, and the variable results show that you got a 2.5 R t. (also  Z-value). The p-value for this Z-value is 0.0124.

Here,

To find the z-scores corresponding to the oldest and youngest senators of age 86% and 41%, respectively, we can use the standard normal distribution formula:

z = (x - μ) / σ

where z is the z-score, x is the given value, μ is the mean, and σ is the standard deviation.

For the oldest senators of age 86%, we can find the corresponding z-score as follows:

z = (x - μ) / σ

z = (0.86 - 0.5) / 0.3413

z = 1.055

Rounding to two decimal places, the z-score is 1.06.

For the youngest senators of age 41%, we can find the corresponding z-score as follows:

z = (x - μ) / σ

z = (0.41 - 0.5) / 0.3413

z = -0.264

Rounding to two decimal places, the z-score is -0.26.
