Approximately 68% of data lies between 0 and 1 standard deviation in the standard normal curve.

The area under the standard normal curve is equal to 1. It is divided into four sections: below 0 standard deviation, between 0 and 1 standard deviation, between 1 and 2 standard deviations, and above 2 standard deviations. Each of these sections has an area of 0.25, or 25%. The area between 0 and 1 standard deviation is 0.25, or 25%, of the entire area under the curve, so 68% of the data lies within it.

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 missing side of the first triangle is 125' and the angle is 20.61°.

the missing side of the second triangle is 117' and the angle is 69.39°.

Having three edges and three vertices, a triangle is a three-sided polygon. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.

Given the two triangles are congruent,

Triangle congruence: If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. These triangles can be turned, flipped, rotated, and slid to create an identical appearance.

we can compare both the triangles and the remaining dimensions of triangle 1 are side = 125' and angle = 20.61°

and dimensions of second triangle are,

side = 117' and angle = 69.39°

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.

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.

In mathematics, a translation is the up, down, left, or right movement of a shape. Because the translated shapes appear to be exactly the same size as the original ones, they are consistent with one another. Just one or more directions have been altered. There is no change in the shape because it is simply being moved from one location to another.

Answer:

m = 50kg

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]

Replacing in the expression for the calculation of the weight:

980 N= m× 19.6 [tex]\frac{m}{s^{2} }[/tex]

Solving:

[tex]\frac{980N}{19.6\frac{m}{s^{2} } }[/tex]

The dynamic range for a 9-bit magnitude PCM code is 3072 dB.

The dynamic range for a 9-bit magnitude PCM code is the difference between the maximum and minimum representable amplitude levels, which is calculated using the formula:

Dynamic range = (2^n - 1) * 6dB

where n is the number of bits used to represent each sample in the PCM code.

For a 9-bit magnitude PCM code, n = 9, so the dynamic range is:

Dynamic range = (2^9 - 1) * 6dB = (512 - 1) * 6dB = 3072dB

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).
