What is square and square roots?The square root of a number is the part of the number that, when multiplied by itself, produces the original number. Squares and square roots are examples of special exponents. The portion of a number that yields the original number when multiplied by itself is known as the square root of the number.
Examples of special exponents include squares and square roots. Think about the number 9. Nine is the result of multiplying 3 by itself. This can be expressed as either or 3*3. We refer to this as a square since it has a 2 exponent. When the exponent is now 1/2, the integer's square root is being discussed.
An integer or number (not a fraction) multiplied by itself produces a "Square Number," which is the result. For instance, 3 x 3 = or 3 squared is the result of 3 times 3.
Given:
√x+11 = 0
√x = -11
can be written as
x = -11²
x = 121
The value of x that best represent the expression √x+11 = 0 is 121.

At a sale this week, a sofa is being sold for $173.60. This is a 72% discount from the original price.
What is the original price?
The original price of the sofa before the discount is $241.11.
What are percentages?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Let the original price of the sofa be x.
Given that 72% of the original price is $173.60, this can be written mathematically as follows:
72/100 × x = 173.60
72x = 17360
x = 241.11

a fictional country has a population of 5 million people and a net immigration rate of 1 person per 1000 people. the population is only increasing due to immigration. how long will it take the country's population to double?
The time it takes for the country's population to double is 1000 years. The total population would be 10 million people.
How to calculate the population growth?We can calculate the population growth by
P = P₀ × r × t
Where
P = population growthP₀ = current populationr = growth raten = number of periodsSuppose that immigration is the only factor of population growth. We have
Net immigration rate, i = r = 1/1000The current population, P₀ = 5 million peopleFind the time that takes the country's population to double!
To make the country's population double, the population growth should be also 5 million people.
The formula would be
5,000,000 = 5,000,000 × 1/000 × t
t = 1,000/1
t = 1,000 years
Hence, the country's population will be double after 1,000 years.

Claire has no more than $45 to spend on a new dress. If x represents the amount Claire can spend, which inequality represents the possible prices of the new dress?
The possible prices of the new dress must be any value less than or equal to $45.
In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.
The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. Finding the x numbers for which the inequality holds true is what we are most interested in.

Answer:
24 days = 1500 tables
25 days = Fewer than 1500 tables
Step-by-step explanation:
So we have the inequality of < which is fewer than. Let's start by labeling all the numbers given.
What we want to find is how many days, so we'll make days = x
2100 is the initial and they sell 25 a day... 25 a x.
Combining them all we get a basic inequality of:
2100 - 25x < 1500
Let's get X alone.
Subtracting 2100 from both sides gives you
-25x < -600.
We have negatives on both sides. For me, if I see that, I make both of them positive;
25x < 600
Last step is to divide the 25 out of the X which means you'll divide 25 by 600 also
X = 24
Which means day 24 will be exactly 1500. We wanted fewer though, so adding a day gives you an answer of 25 days.
if she needs to allocate her waking time of 15 hours between these two activities, how much studying is she going to do per day?
She would be doing 9 hours of studying per day and 6 hours of other activities. This is because 15 hours divided by 9 hours of studying and 6 hours of other activities would equal the same amount of time allocated to each activity.
The amount of studying she is going to do per day is 9 hours, and the amount of other activities she is going to do per day is 6 hours. This means that she will be dedicating roughly 60% of her waking hours to studying and 40% to other activities. This is a good balance between the two activities, and it will ensure that she is able to adequately focus on both her studies and other activities.
This balance will also help her to stay motivated and not become overwhelmed by her studies. Having a set amount of time for both activities will also help her to organize her day and stay on track. It will give her a sense of structure and allow her to plan her day accordingly.

For the given similar triangles, the value of x = 5.
What are similar triangles used for?Similar triangles share the same associated angle measurements and proportional side lengths.
Due to their similar shapes, two figures that are not always the same size can appear comparable. We might claim, for instance, that all circles are equivalent. Squares and equilateral triangles share similar characteristics. Although similar figures need not be congruent in order to be comparable, congruent figures are always comparable.
Despite having the same shape, similar triangles have different diameters. In identical triangles, corresponding angles are equal. In analogous triangles, the ratio of the corresponding sides is the same. Any pair of equivalent sides' squares and any comparable triangle's area have the same ratio.
As the given triangles are similar,
the sides are in same ratio,

the proportion of defective electronic items in a shipment has the beta distribution. find the probability that at least 30% of the items in the shipment are defective (round off to second decimal place).
The probability that at least 30% of the items in the shipment are defective is 0.7360.
The beta distribution with parameters (3,3) is the conjugate prior for the binomial distribution with a probability of success of p, where 0<p<1.
The binomial distribution is a probability distribution that describes the number of successes in a fixed number of Bernoulli trials. A Bernoulli trial is a random experiment with two possible outcomes: success or failure. In the context of the problem you presented, success would be a defective item, and failure would be a non-defective item.
To find the probability that at least 30% of the items in the shipment are defective, we can use the cumulative distribution function (CDF) of the beta distribution. The CDF of the beta distribution is given by:
F(x;a,b) = (x^(a-1) * (1-x)^(b-1)) / B(a,b)
where x is the proportion of defective items, a and b are the shape parameters, and B(a,b) is the beta function.
We want to find P(X >= 0.3) where X is the proportion of defective items. Substituting the values for a, b, and x we get
P(X >= 0.3) = 1 - P(X < 0.3)
= 1 - F(0.3;3,3)
= 1 - ((0.3^(3-1) * (1-0.3)^(3-1)) / B(3,3))
= 1 - ((0.3^2 * 0.7^2) / (1/6))
= 1 - ((0.09 * 0.49) / (1/6))
= 1 - (0.044/0.1666)
= 1 - 0.2640
= 0.7360
Therefore, The probability that at least 30% of the items in the shipment are defective is 0.7360.
