describe an incident that shows how you were doing "selection" during the process of perception. Then, give your own example about a stereotype that you do.
Answers
The description of the incident is shown below
Describing the incidentOne incident that shows how selection works in the process of perception is when you are at a party and you hear your name being mentioned in a conversation across the room. In this situation, your attention is immediately drawn to the conversation, and you focus on it while filtering out other sounds and distractions around you.
This is an example of selective attention, where you choose to focus on a particular stimulus and ignore others.
As for an example of a stereotype that I have, it is that all people who live in a certain region or country behave in a particular way.
For instance, I may have the stereotype that people from a particular country are loud and aggressive.

5) ∠1 and ∠3
6) x = 10
Step-by-step explanation:
Adjacent angles are two angles that share a common vertex and a common side, but do not overlap.
Therefore, the pairs of adjacent angles in the given diagram are:
∠1 and ∠2∠2 and ∠3∠3 and ∠4∠4 and ∠5∠5 and ∠1Vertical angles are pairs of non-adjacent angles that are formed when two lines intersect. Vertical angles are congruent,
Therefore, the pair of vertical angles in the given diagram are:
∠1 and ∠3As ∠1 and ∠3 are the same measure:
⇒ m∠1 = m∠3
⇒ (9x)° = 90°
⇒ 9x = 90
⇒ 9x ÷ 9 = 90 ÷ 9
⇒ x = 10
Therefore, the value of x is 10.

What is a rectangle?An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°).
A rectangle has equal and parallel opposite sides.
A rectangle has two dimensions—length and width—because it is a two-dimensional form.
The rectangle's longer side is its length, while its shorter side is its breadth.
So, the area formula of the rectangle:
750 = l * w
750 = x * (x-5)
750 = x² - 5x
x² - 5x - 750 = 0
Equations in the options that are similar:
(A) y(y + 5) = 750

Answers
The tax rate of a house valued at $115,000 with a property tax of $1265 is 110%. or $110 per $1,000 of property value.
What is property tax?The property tax is the levy imposed on the assessed value of the property of an individual or corporation.
Property tax is usually levied as a percentage of the assessed value.
Data and Calculations:Property tax = $1265
House value - $115,000
Tax rate = 110% [tex](\$1265\div\$115000 \times 100)[/tex]

Alg 2 graphic quadratics in intercept form
Answers
The calculated key features of the quadratic functions 1 to 6 are listed below
Completing the key features of the graphsFunction 1: y = 1/2(x + 4)(x - 2)
Expand
y = x^2/2 + x - 4
From the function, we have
a = 1/2 (coefficient of x^2 term)
p = -b/2a (x-coordinate of the vertex)
p = -(1)/2(1/2)
p = -1
q = f(p) (y-coordinate of the vertex)
q = 1/2(1 + 4)(1 - 2)
q = -5/2
From the function, we have
x-intercepts = (-4, 0) and (2, 0)
This also means that the axis of symmetry is
x = -1
The quadratic function opens up because the coefficient of the x^2 term is positive.
Next, we have
Vertex = (-1, -5/2)
For the y-intercept, we have
y-intercept = f(0)
y-intercept = 1/2(0 + 4)(0 - 2)
y-intercept = -4
Slope to a point one unit from the vertex can be found by taking the derivative of the function:
f(x) = x^2/2 + x - 4
f'(x) = x + 1
At x = -2 (one unit to the left of the vertex), the slope is -1
i.e. f'(-2) = -2 + 1 = -1
At x = 0 (one unit to the right of the vertex), the slope is 1.
i.e. f'(0) = 0 + 1 = 1
When the above steps is repeated for the remaining functions, we have the following results:
Function 2: y = 1/2x(x - 8)

The state of Colorado is 4 centimeters long and 2 centimeters wide on a map. A cartographer wants to use a scale factor of 3.5 to enlarge the map. What is the area of the enlarged map?
98 cm2
42 cm2
28 cm2
8 cm2
Answers
Answer: 98 cm²
Step-by-step explanation:
When a cartographer enlarges a map with a scale factor, both the length and the width are multiplied by the scale factor. In this case, the scale factor is 3.5.
Original dimensions of Colorado on the map:
Length: 4 cm
Width: 2 cm
Enlarged dimensions using the scale factor of 3.5:
Length: 4 cm × 3.5 = 14 cm
Width: 2 cm × 3.5 = 7 cm
To find the area of the enlarged map, multiply the enlarged length and width:
Area = Length × Width
Area = 14 cm × 7 cm
Area = 98 cm²
The area of the enlarged map is 98 cm².

Answers
Answer:
[tex]f(x)=-3x^2+5[/tex]
[tex]f(2) = -7[/tex]
Step-by-step explanation:
Given equation:
[tex]y+3x^2=5[/tex]
To solve the equation for y in terms of x, simply subtract 3x² from both sides of the equation:
[tex]\implies y+3x^2-3x^2=5-3x^2[/tex]

if triangle ABC is translated 5 units down, the image's coordinates are A′(1, 7), B′(9, 7), and C′(5, 3).
The x and y coordinates of each of a triangle's vertices must be added to or subtracted from to translate the triangle on a coordinate plane.
Triangle ABC must be translated five units lower in this situation. Thus, we must deduct 5 from the y coordinates of each of its vertices.
A(1, -2) changes to A' (1, -7) B(9, -2) changes to B' (9, -7) C(5, 2) changes to C' (5, -3)

Answers
Answer:
we need to add the money Andy earned to the negative balance he had. So, we have:
-$45 + $30 + $25 = $10
Therefore, Andy now has $10 in his checking account.
Answer:
Andy now has $10 in his checking account.
Step-by-step explanation:
Andy starts the week with -$45 in his checking account. When he gets paid $30 for mowing the grass and $25 for vacuuming the house, his total earnings for the week are:
$30 + $25 = $55
To find out how much money he now has in his checking account, we need to add his earnings to his starting balance of -$45. Adding a negative number is the same as subtracting a positive number, so we can write this as:
-$45 + $55 = $10
Therefore, Andy now has $10 in his checking account.

A)calculate the FPCF for this sample
B)Should the population be considered effectively infinite
DO BOTH A AND B URGENT
Answers
A) The FPCF for this sample is 0.899. B) The sample size is about 12% of the population size, which is relatively large.
A) The FPCF (Finite Population Correction Factor) is used to adjust for the impact of a finite population on the sampling distribution. The formula for the FPCF is:
FPCF = [tex]\sqrt{((N-n)/(N-1))}[/tex]
where N: size of the population and n: size of the sample.
In this case, the population size is N = 199, and the sample size is n = 24. Therefore, the FPCF can be calculated as follows:
FPCF = [tex]\sqrt{((199-24)/(199-1))}[/tex] = 0.899
So, the FPCF for this sample is 0.899.
B) In general, a population can be considered effectively infinite when the sample size is no more than 5-10% of the population size. In this case, the sample size is n = 24, and the population size is N = 199. Therefore, the sample size is about 12% of the population size, which is relatively large.

The federal government has developed the body mass index (bmi) to determine ideal weights. a person's bmi is directly proportional to his or her weight in pounds and inversely proportional to the square of his or her height in inches. (a bmi of 19 to 25 corresponds to a healthy weight.) a 6-foot-tall person weighing 177 lb has bmi 24. find the bmi (to the nearest whole number) of a person whose weight is 176 lb and whose height is 77 in.
Answers
The BMI of a person whose weight is 176 lb and whose height is 77 inches is 21.
First, let's use the given information to find the constant of proportionality in the BMI formula:
BMI = k × (weight in pounds) / (height in inches)²
When the 6-foot-tall person weighing 177 lb has a BMI of 24, we can plug in the values and solve for k:
24 = k ₓ 177 / (72²)
k = 24 ₓ (72²) / 177
k ≈ 9.94
Now we can use this value of k to find the BMI of the person whose weight is 176 lb and whose height is 77 in:
BMI ≈ 21
BMI = 9.94 ₓ 176 / (77²)
Therefore, the BMI (to the nearest whole number) of the person is 21, which falls within the healthy weight range of 19 to 25.
