In a normal distribution, what percentage of the data falls within 3 standard
deviations of the mean?
O A. 34%
O B. 68%
O c. 99.7%
O D. 95%

Answers

Using the Empirical Rule, it is found that the percentage within 3 standard deviations of the mean in the Normal distribution is given by:

c. 99.7%.

What does the Empirical Rule state?

It states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of  the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.

Hence, option C is correct.

What is the volume of a sphere with a radius of 6.6 cm, rounded to the nearest tenth of a cubic centimeter?

Answers

Volume is a three-dimensional scalar quantity. The volume of a sphere with a radius of 6.6 cm, rounded to the nearest tenth of a cubic centimeter is 1204.3.

What is volume?

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of a sphere is given by the formula (4/3)πR³, where R is the radius of the circle. Since the radius of the sphere is 6.6 cm, the volume of the sphere will be,

Volume of Sphere = (4/3) × π × (6.6cm)³ = 1204.26 cm³ ≈ 1204.3³

Hence, the volume of a sphere with a radius of 6.6 cm, rounded to the nearest tenth of a cubic centimeter is 1204.3.

A group of students stood in a circle to play a
game. The circle had a diameter of 22 meters.
Which measurement is closest to the area of the
circle in meters ?

Answers

Answer: Choice C)  379.94 square meters

=========================================================

Work Shown:

Diameter = 22 meters

Radius = 11 meters (half the diameter)

We'll plug r = 11 into the formula below

A = pi*r^2

A = 3.14*11^2

A = 379.94

This value is approximate since pi = 3.14 is approximate. Use more decimal digits of pi to get a more accurate area value.

Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon.

Round to the nearest tenth, if necessary.

Answers

Answer:

[tex]\theta = 25.7^\circ[/tex] --- Measure of each exterior angle

[tex]\theta = 154.3^\circ[/tex] --- Measure of each interior angle

Step-by-step explanation:

Given [Missing from the question]

[tex]n = 14[/tex] --- number of sides

Required

- The measure of an exterior angle

- The measure of an interior angle

For an n-sided polygon, the measure of each exterior angle is:

[tex]\theta = \frac{360}{n}[/tex]

Substitute 14 for n

[tex]\theta = \frac{360}{14}[/tex]

[tex]\theta = 25.7^\circ[/tex]

For an n-sided polygon, the measure of each interior angle is:

[tex]\theta = \frac{(n - 2) * 180}{n}[/tex]

Substitute 14 for n

[tex]\theta = \frac{(14 - 2) * 180}{14}[/tex]

[tex]\theta = \frac{12 * 180}{14}[/tex]

[tex]\theta = \frac{2160}{14}[/tex]

[tex]\theta = 154.3^\circ[/tex]

What is Function?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.

Given, For g(x)=5 and h(x)=2x

[tex]\lim_{x \to \ a }(g(x)*h(x))[/tex]

=> lim (5 * 2x)

=> lim 10x

=> 10a

for  G(x)= X-10 And H(x)= 2x,

g(x)/ h(x) = (x - 10)/2x

[tex]\lim_{x \to \ -2} g(x)/ h(x)[/tex]

=> (-2- 10)/-4

=> 3

therefore, the value of function lim (g(x)*h(x)) will be 10 a.

y=-16x^2+174x+78
equation

Answers

Answer:

551.06feet

Step-by-step explanation:

Given the equation

y=-16x^2+174x+78

At maximum height, dy/dx = 0

dy/dx = -32x + 174

0 = -32x+174

32x = 174

x = 174/32

x = 5.4375

GEt the maximum height

y=-16x^2+174x+78

y=-16(5.4375)^2+174(5.4375)+78

y = -473.0625 + 946.125 + 78

y = 551.0625

Hence the maximum height is 551.06feet to the nearest hundredth

Identify the following as a radius or diameter and its length. segment EB

Answers

Given:

The diagram of a circle.

To find:

The radius or diameter and its length, segment EB.

Solution:

If a line segment connects the center of a circle and a point on the circumference of the circle, then the line segment is known as radius.

In the given figure A is the center of the circle and points B, C, E, D are on the circumference of the circle.

So, AB, AC, AE, AD are radii of the given circle.

[tex]AB=AC=AE=AD=4\text{ cm}[/tex]

If a line segment connects two points on the  circumference and passes through the center of the circle, then the line segment is known as diameter of the circle.

In the given figure B and E are two points on the circumference of the circle and the segment BE  passes through the center A. So, BE is the diameter of the circle.

Length of the diameter is:

[tex]EB=AE+AB[/tex]

[tex]BE=4+4[/tex]

[tex]BE=8[/tex]

Therefore, the segment EB is a diameter and length of the segment EB is 8 cm.
