Answer:

Definition: Scaled Drawing. A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount

Example

Example #1:

Suppose a problem tells you that the length of a vehicle is drawn to scale. The scale of the drawing is 1:20.

If the length of the drawing of the vehicle on paper is 12 inches, how long is the vehicle in real life?

Set up a proportion that will look like the formula above picture

A scale drawing proportion

Do a cross product by multiplying the numerator of one fraction by the denominator of the other fraction

We get :

Length of drawing × 20 = Real length × 1

Since length of drawing = 12, we get:

12 × 20 = Real length × 1

240 inches = Real length

The real length of the vehicle is 240 inches.

2)Circumference of circle: The distance around the circular region is called its circumference. The ratio of circumference of any circle to its diameter is constant. ... Area of circle: The measure of the region enclosed inside the circle is called its area.

Answer:

a)Both X and Y can be well approximated by normal random variables.

Step-by-step explanation:

For each individual, there are only two possible outcomes. Either they are right-handed, or they are left-handed. This means that we can solve this problem using concepts of the binomial probability distribution.

Binomial probability:

Probability of exactly x sucesses on n repeated trials, with probability p.

The binomial probability can be well approximated by normal random variables, using the expected value E(X) = np and the standard deviation \sigma = \sqrt{np(1-p)}

Let X be the number of males (out of the 100) who are left-handed.

n = 100 and p = 0.13. Can be well approximated.

Let Y be the number of females (out of the 80) who are left-handed.

n = 80 and p = 0.11. Can be well approximated.

The correct answer is

a)Both X and Y can be well approximated by normal random variables.

A company designs a logo using a kite figure around the letter t. The logo is 12 centimeters wide and 16 centimeters tall. What
Temka [501]

Answer:

96 sq. cm.

Step-by-step explanation:

A "kite" has 2 diagonals, which are the "width" and "height" of the kite.

Using diagonals, the area of a kite is given by  A=\frac{pq}{2}

Where

A is the area

p,q are the width and height, respectively

From the problem given, p is 12 and q is 16, so the area is:

A=\frac{pq}{2}\\A=\frac{(12)(16)}{2}\\A=96

Thus, the area is 96 sq. cm
