What is the area of a circular region whose
diameter is 12 centimeters?

Answers

Answer 1

Answer:

A circle of radius = 12 or diameter = 24 or circumference = 75.4 cm has an area of: 4.524 × 10-8 square kilometers (km²)

Answer 2

The area of the circular region will be 113 square centimeters.

What is an area?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.

The formula to calculate the area of the circle is given by:-

A = πr²

Given that the diameter of the circular region is 12 centimeters. The radius will be half of the diameter.

r = d / 2

r = 12 / 2 = 6

The area of the region will be calculated as below:-

A = πr²

A = π x ( 6 ) x ( 6 )

A = 113.09 square centimeters

Therefore, the area of the circular region will be 113 square centimeters.

Identify the angles , solve for x

Answers

Answer:

Consecutive interior angles ; x = 20

Step-by-step explanation:

These are known as consecutive interior angles. This means they are equal to each other. Knowing this, we can set up an equation to solve for x.

4x - 30 = 2x + 10

2x - 30 = 10

2x = 40

Function A and Function B are linear functions. Compare the two functions and choose all that are correct. Can someone help?

Answers

Answer:

(b) and (c) are true

Step-by-step explanation:

Given

Function A and B

First, calculate the slope of A

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{24 - -21}{8- -7}[/tex]

[tex]m = \frac{45}{15}[/tex]

[tex]m =3[/tex]

The equation of function A is:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 3(x - 8) + 24[/tex]

[tex]y = 3x - 24 + 24[/tex]

[tex]y = 3x[/tex]

The general form of a function is:

[tex]y = mx + b[/tex]

Where [tex]m = slope[/tex] and [tex]b = y\ intercept.[/tex]

This implies that:

[tex]Slope = 3[/tex]

[tex]Y\ intercept = 0[/tex]

For function B:

[tex]y = 4x - 3[/tex]

[tex]Slope = 4[/tex]

[tex]Y\ intercept = -3[/tex]

Answers

Answer:

So equation will be 4x = 10

A 10 ounce container of chocolate chips can be used to make 4 desserts.

Each desert has the same number of chocolate chips

Let number of chocolate chips in each dessert = x ounce

Therefore, chocolate chips in 4 deserts = 4x and total chocolate chips is = 10 ounce.

A large operator of timeshare complexes requires anyone interested in making a purchase to first visit the site of interest. Historical data indicates that 20% of all potential purchasers select a day visit, 50% choose a one-night visit, and 30% opt for a two-night visit. In addition, 30% of day visitors ultimately make a purchase, 10% of one-night visitors buy a unit, and 50% of those visiting for two nights decide to buy. Suppose a visitor is randomly selected and is found to have made a purchase. How likely is it that this person made a day visit

Answers

Answer:

0.2308 = 23.08% probability that this person made a day visit

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Visitor made a purchase

Event B: Made a day visit

Probability that a visitor made a purchase:

30% of 20%(day visitors)

10% of 50%(one-night)

50% of 30%(two-night)

So

[tex]P(A) = 0.3*0.2 + 0.1*0.5 + 0.5*0.3 = 0.26[/tex]

Probability of a purchase with a day visit:

30% of 20%. So

[tex]P(A \cap B) = 0.3*0.2 = 0.06[/tex]

How likely is it that this person made a day visit?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.06}{0.26} = 0.2308[/tex]

0.2308 = 23.08% probability that this person made a day visit
