In the figure below, angle ABD measure 41°. what is the measure of angle ABC?

The process of grouping and assigning values to various responses from the survey instrument is called

adoni [48]

The term used to describe the process of assigning values to responses in a research instrument and grouping them is called: coding.

<h3>What is Coding in Research Analysis?</h3>

In data analysis, before raw data can be processed, the researcher groups and assigns values to each response in the research instrument for easy collation and analysis.

This is referred to as coding, in research analysis.

The function p(x) = _2(x _ 9)2 + 100 is used to determine the profit on T-shirts sold for x dollars. What would the profit from

Valentin [98]

Answer:

Option (b) is correct.

The profit from sales if the price of the T-shirts were $15 a pieces is $28.

Step-by-step explanation:

Given : The function $p(x)=-2(x-9)^2+100$ is used to determine the profit on T-shirts sold for x dollars.

We have to find the profit from sales if the price of the T-shirts were $15 a pieces.

Consider the given profit function $p(x)=-2(x-9)^2+100$

For the profit, if the price of a t-shirt is $ 15

Put x = 15, we have,

$p(15)=-2(15-9)^2+100$

Simplify, we have,

$p(15)=-2(6)^2+100=-2\cdot 36+100$

Also, $p(15)=-72+100=28$

Thus, we get, The profit from sales if the price of the T-shirts were $15 a pieces is $28.

In the figure below, a shaded polygon, which has equal sides and equal angles, is partially covered with a sheet of blank paper.

Zepler [3.9K]

Answer:

The polygon has 9 sides ⇒ D

Step-by-step explanation:

This is a tricky question

∵ The shaded figure is a quadrilateral

∴ The sum of the measures of its angles is 360

∵ Its angles are x, y, and two vertices of the polygon

∵ All angles of the polygon are equal in mesures

∴ x + y + m of 2 vertices = 360°

∵ x + y = 80

→ Substitute the value of x + y above by 80

∴ 80 + m of 2 vertices = 360

→ Subtract 80 from both sides

∴ m of 2 vertices = 280

→ Divide the two sides by 2

∴ m of 1 vertex = 140°

∴ The measure of each angle of the polygon is 140°

The sum of the measures of the interior angle and the exterior angle at any vertex of the polygon is 180°

∵ m of interior ∠ + m of exterior ∠ = 180° ⇒ at any vertex

∴ 140 + m of exterior ∠ = 180°

→ Subtract 140 from both sides

∴ m of exterior ∠ = 40°

∴ The measure of each exterior angle is 40°

The sum of the measures of the exterior angles of any polygon is 360°

∵ The measure of each exterior angle of the given polygon is 40°

∴ The number of the angles of the polygon = 360 ÷ 40 = 9

∵ The number of the angles of the polygon = the number of its sides

∴ The polygon has 9 sides

Mike and talia each make a scale drawing of the right side of their house. The scale of the side of the actual house to Mikes dr

Nutka1998 [239]

The width and height of Talia's Scale drawing are :

Width = 4.35 in
Height = 5.7 in

We can obtain the actual length of the side of the house from Mike's drawing :

Mike's scale = 3 ft to 1 in

Actual measurements:

Scale ratio × model drawing
Height, h = 9.5 × 3 = 28.5 feets
Width, w = 7.25 × 3 = 21.75 feets

Measurement of Talia's Scale drawing :

Talia's scale = 5 ft to 1 in
Actual measurement ÷ scale
Height = 28.5 ÷ 5 = 5.7 in
Width = 21.75 ÷ 5 = 4.35 in

The width and height of Talia's scale drawing are 5.7 and 4.35 respectively.

If the difference between a number and 21 is divided by2, the result is 4 times the number. What is the number

Ostrovityanka [42]

(n-21)/2=4n is the equation

First, divide what is in the parentheses by 2
0.5n-10.5=4n

Then, multiply the whole equation by 2 so we have all whole numbers
n-21=8n

Move N so that it is with 8n
7n=-21

Divide 21 by 7
n=-3

Solution: The number (n) is equal to -3
