What is the length of Line segment B C?

The level of scale of measurements is the ratio scale for the data of the average weight of newborn babies in ounces.

There are four scales of measurement: Nominal, Ordinal, Interval, and Ratio.

Nominal scale: In this scale, categories are nominated names (hence “nominal”). There is no inherent order between categories. Put simply, one cannot say that a particular category is superior/ better than another.

Ordinal scale:  The various categories can be logically arranged in a meaningful order. However, the difference between the categories is not “meaningful”.

Interval scale:  The values (not categories) can be ordered and have a meaningful difference, but doubling is not meaningful. This is because of the absence of an “absolute zero”.

Ratio scale:  The values can be ordered to have a meaningful difference, and doubling is also meaningful. There is an “absolute zero”.

Therefore, the level of scale of measurements is the ratio scale for the data of average weight of newborn babies in ounces.

What is a sequence?

an arrangement of two or more things in successive order. the sequential arrangement of two or more things The chronological order. a list of things or ideas that are related in some way. an action or event that follows another or others.

Given that, a₁ = 3 and a₃ = 192.

The sequence is increased rapidly. Thus it is geometric progress.

Assume that the common ratio of the geometic sequence is r.

The nth term of the sequence is [tex]a_n =a(r^{n-1})[/tex]

=[tex]3r^{n-1}[/tex] since a is the first term that is a = 3.

Putting n=3 in the sequnce:

a₃ = 3(r)²

Putting a₃ = 192 in the above equation:

192 = 3(r)²

Divide both sides by 3:

192/3 = r²

r² = 64

r = ±8

When r = 8:

In a triangle one side that lies on an extended line segment,  statement about x is true, x = 62 because 147−85=62 and 85 + 62 = 147. So Option B is correct

In mathematics, the triangle is a type of polygon which has three sides and three vertices. the sum of all the interior angles of the triangle is 180°

Given that,

A triangle, which has one interior angle 85° and one exterior angle 147°

Another exterior angle x = ?

It is already known that,

Sum of complementary angles are 180

So,

⇒  Y + 147 = 180

⇒  Y  = 180 - 147

⇒  Y = 33

sum of all the interior angles of the triangle is 180°

X + Y + 85 = 180

X = 180 - 85 - 33

X = 62

Hence, the value of x is 62

The four basic properties of exponents are the negative exponent property, the product of powers property, the quotient of powers property, and the power of a power property.

The properties of exponents are a set of rules that allow us to simplify terms that contain exponents.

Negative exponent property states that when a negative exponent is present, the base and the exponent are switched and the sign of the exponent is changed. For example,  x-2 = 1/x2.

The product of powers property states that when two terms with the same base are multiplied, the exponents are added together. For example, x3 x4 = x7.

The quotient of powers property states that when two terms with the same base are divided, the exponents are subtracted. For example, x6/x2 = x4.

The power of a power property states that when a term with an exponent is raised to another power, the exponents are multiplied. For example, (x3)2 = x6.

These properties can be used to simplify expressions that contain exponents. For example, the expression (−2m−2????4) 3 can be simplified using the power of a power property by multiplying the exponents. The expression simplifies to −2m−6????12.

Answer:

m∠EPA = 68°

Step-by-step explanation:

Angle EPA is adjacent to angle PAC in parallelogram PACE.

As adjacent angles in a parallelogram sum to 180°:

⇒ m∠PAC + m∠EPA = 180°

⇒ 112° + m∠EPA = 180°

⇒ 112° + m∠EPA - 112° = 180° - 112°

⇒ m∠EPA = 68°

Therefore, the measure of angle EPA is 68°.

The volume of a sphere with a radius of 16cm is approximately 17157.28 cm^3

The volume of a sphere can be calculated using the formula

V = 4/3 * π * r^3, where V is the volume, π is approximately 3.14, and r is the radius of the sphere. In this case, the radius of the balls used by the stock person is 16cm. Therefore, we can substitute this value into the formula to find the volume of each ball.

V = 4/3 * π * r^3

V = 4/3 * 3.14 * (16cm)^3

V = 17157.28cm^3

So, the volume of each ball is approximately 17157.28cm^3.

It is important to keep in mind that the volume of a sphere is dependent on the radius of the sphere, so if the radius of the balls were different, the volume would also be different.

If earth days merely 2 hours long, which means the rotation period of the earth is 2 hours, your weight will become 1/144 of your actual weight.

The weight or gravitational force on a mass can also be considered as centripetal force.

The formula for the centripetal force is:

F = m v²/R

In this case,

m = your mass

v = tangential velocity or earth's rotation speed

R = earth's radius

Recall that speed = distance / time. In the problem, the distance is the circumference of the earth and the travelled time is the rotation period.

v = C/t

t₁ = 24 hours

t₂ = 2 hours

Since the units are the same, we do not need to convert the unit when comparing them.

Notice that the centripetal force is directly proportional to the square of rotation speed.

F ∝ v²

Hence,

F₁ : F₂ = v₁² : v₂²

But v is inversely proportional to rotation period. Hence,

F₁ : F₂ = t₂² :  t₁²

F₁ / F₂ = (t₂ /t₁)²

F₁ / F₂ = (2 /24)²

F₁ / F₂ = (1 /12)²

F₁ / F₂ = 1/144

Hence, your weight will be 1/144 of your actual weight.

The probability that a sample taken from the site will have water content above 12% and below 16% is 0.6102.

To calculate the probability that a sample taken from the excavation site will have water content above 12% and below 16%, we need to find the proportion of the normal distribution that falls between those two values.

First, we need to standardize the values by subtracting the mean and dividing by the standard deviation.

The value of 12% will be standardized as (12-14.2)/2.3 = -0.9565 and,

the value of 16% will be standardized as (16-14.2)/2.3 = 0.7826.

Using a standard normal table, we can find the probability that a standard normal variable is less than -0.9565 and 0.7826

The probability that Z < -0.9565 is approximately 0.1687

The probability that Z < 0.7826 is approximately 0.7789

Therefore, the probability that a sample taken from the excavation site will have water content above 12% and below 16% is:

P(12 < X < 16) = P(Z < 0.7826) - P(Z < -0.9565) = 0.7789 - 0.1687 = 0.6102 or 61.02%

Domain and Range. The domain of a function is the set of values that we are allowed to plug into our function.

Range and Domain. The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Important values that aid in defining a relation include domain and range. The collection of input values is the domain. These values are graphed on the axis of a coordinate graph and are represented by the independent variable. The collection of output values for a function is known as the range.

An further method to determine the domain and scope of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

To find the domain and range of a function without a graph is to use algebraic methods.

What is domain in function ?

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

One way to find the domain and range of a function without a graph is to use algebraic methods. For example, if the function is defined by an equation, you can solve for the variables to determine the domain and range. You can also use inequalities or interval notation to express the domain and range.

Another way to find the domain and range is to examine the function's definition and identify any restrictions on the input or output values. For example, if a function is defined in terms of a square root, the input values must be non-negative to avoid a complex output.
