The call center received a number of calls between 3:00 PM and 4:00 PM is 350.

A call center (Commonwealth spelling) or call center (American spelling; see spelling differences) is a managed capability that can be centralized or remote that is used for receiving or transmitting a large volume of inquiries by telephone. An inbound call center is operated by a company to administer incoming product or service support or information inquiries from consumers. According to this question,

The call center received 40% more inquiries between 3:00 PM and 4:00 PM than the 250 inquiries received between 2:00 PM and 3:00 PM.

So, if 250 inquiries were received between 2:00 PM and 3:00 PM, 40% of that is 250 * 40% = 100.

And the total number of inquiries received between 3:00 PM and 4:00 PM is 250 + 100 = 350.

Therefore, the call center received a number of calls between 3:00 PM and 4:00 PM is 350.

The height of the Public Park entreence in smaller scale is 7.9 inches

The actual height of the Park entrence is 7.9*48 = 379.2 inches = 31 feet 7.2 inches

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Direct Variation

When there is a direct variation, an increase or decrease in one quantity will result in an equivalent rise or fall in the other. For instance, a rise in the quantity of commodities will result in higher costs.

Indirect Variation

A change in one quantity will directly affect a change in another, known as a direct variation. A rise in the quantity of goods, for instance, will result in higher costs.

Step-by-step explanation:

Here's a step-by-step explanation to find the three consecutive numbers whose sum is 42:

Let's call the smallest of the three numbers "x".

Since they are consecutive numbers, we can represent the next two numbers as x+1 and x+2.

The sum of these three numbers can be represented as x + (x + 1) + (x + 2) = 42.

Simplifying this equation, we get 3x + 3 = 42.

Subtracting 3 from both sides, we get 3x = 39.

Dividing both sides by 3, we get x = 13.

So, the three consecutive numbers are 13, 14, and 15.

When conducting a chi-square test for a 2 by 2 contingency table, the null hypothesis tested is the two variables are independent of each other.

The chi-square test is a statistical method used to analyze the relationship between two categorical variables.

Here we need to determine whether the null hypothesis can be rejected, the chi-square test compares the observed frequencies of the two variables with the expected frequencies.

If the difference between the observed and expected frequencies is large enough, it can be concluded that the two variables are not independent, and the null hypothesis can be rejected.

It's important to note that the chi-square test is only appropriate for 2 by 2 contingency tables, where both variables being studied are categorical and have only two categories each. Additionally, the sample size must be large enough to allow for valid statistical inference.

In the chi-square test for a 2 by 2 contingency table is used to determine if there is a significant relationship between two categorical variables, with the null hypothesis being that the two variables are independent of each other.

The solution to the system is (x, y) = (7, 5).

What is the linear equation?

A linear equation is an equation of a straight line. It is an equation of the form y = mx + b, where m is the slope of the line and b is the y-intercept.

The system has one solution (7,5).

One method to solve the system of linear equations is substitution. From the first equation, x = y + 2. Substituting this into the second equation, we get -3(y + 2) + 3y = 6, which simplifies to -3y - 6 + 3y = 6.

Combining like terms, we get -3y = -6, or y = 2.

Finally, substituting y = 2 back into x = y + 2, we get x = 2 + 2, or x = 4. So, the solution to the system is (x, y) = (7, 5).

The percentage change in GDP over the time period from 2010 to 2011 was 4.14%. This means that the nominal GDP increased by 4.14% during this time period.

To calculate the percentage change in Gross Domestic Product (GDP) over the time period from 2010 to 2011, we can use the following formula:

Percentage change = (GDP in 2011 - GDP in 2010) / GDP in 2010 * 100%

Substituting the values, we get:

Percentage change = ($15.1 trillion - $14.5 trillion) / $14.5 trillion * 100% = $0.6 trillion / $14.5 trillion * 100% = 4.14%

So, the percentage change in GDP over the time period from 2010 to 2011 was 4.14%. This means that the nominal GDP increased by 4.14% during this time period.

The value of x from pythagoras theorem we get as 32.45

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Let the length of the perpendicular be y , the length of the 3rd side be z

Using Pythagoras Theorem :

x² - y² = 27² , ............(i)

x² + z² = (27 +9)² = 36² .......(ii)

y² - z² = 9²   ................(iii)

The probability of rolling a die 2 times and then rolling 2 odd numbers in a row is 1/4

When rolling a fair six-sided die, each outcome has an equal chance of happening, so the probability of rolling an odd number is 1/2 i.e. 3 out of 6

The probability of rolling two odd numbers in a row is then

(1/2) * (1/2) = 1/4.

This means that, the probability of rolling a die two times and then rolling 2 odd numbers in a row is 1/4

Answer:

Step-by-step explanation:

First, you  have to know that mass is an indicator of the amount of matter that makes up a body. Its unit in the International System is the kilogram (kg).

The mass of an object will always be the same, no matter where it is located.

On the other side, bodies are subjected to the action of forces, such as the force of gravity or electromagnetic forces.

So, weight is the action exerted by the force of gravity on the body. That is, weight is a measure of how much force gravity exerts on the mass of an object.

The weight of an object is measured in Newton (N) and will vary according to the force of gravity that acts on it.

The expression for the calculation of the weight is:

P= m×g

where:

In this case, you know that:

P= 980 N

m= ?

g= 19.6 [tex]\frac{m}{s^{2} }[/tex]

True, The span of {u, v} contains both the line through u and the origin, as well as the line through v and the origin.

The span of a set of vectors is defined as the set of all linear combinations of those vectors. When u and v are nonzero vectors, the span of {u, v} is a two-dimensional subspace of the vector space that contains both u and v, and any linear combination of u and v.

Since u and v are nonzero vectors, the lines through the origin and u, and through the origin and v, are non-degenerate lines in the vector space. Therefore, these lines are contained within the span of {u, v}.

In other words, if we take any scalar multiples of u and v, such as au and bv, where a and b are scalars, the sum au + bv will be a linear combination of u and v and therefore will also be contained within the span of {u, v}.

Therefore, the span of {u, v} contains both the line through u and the origin, as well as the line through v and the origin.
