Determine if this is a function.
I did the vertical line test, but I'm still a bit confused.
Answer: This is not a function
Why not?
The input x = 2 leads to more than one output. In this case, it leads to y = 20 and y = 40 simultaneously. This is the reason why we don't have a function. A function is only possible if each input x leads to exactly one y output.
Put another way: we cannot have x repeating any values if we want a function.
Side note: We could have y repeat however. So it's possible to have a function with the two points (1,5) and (3,5).
Elise randomly surveyed students at her school to find out their favorite music. the table shows the results if Elise’s survey. if there are 400 students at Elise’s school, how many can she predict will like pop the best?

Step-by-step explanation:
Read the scenarios and decide which type of interaction (absorption or transmission) took place between the wave
and the object.
People are able to hear footsteps because the sound made by a foot hitting the floor travels through the air to reach
their ears.
When light from the sun hits the sidewalk, the sidewalk becomes warmer.
Answer:
transmission absorption
Step-by-step explanation:
This is because the sound of the foot striking the floor is being transmitted through the air. The sun's light is absorbed when it strikes the sidewalk.
What is absorption and transmission?
Absorption is the process or action by which one thing absorbs or is absorbed by another.
The act of sending something, such as a cold or a message, or the component of a machine that transfers power from the engine to the moving parts is known as transmission.
Which process is represented by the given statements?Because of the air pressure, people can hear when their foot strikes the ground. In a similar manner, when sunlight strikes a sidewalk, it warms up as a result of absorbing the heat.
Therefore, the first statement is transmission and second statement is absorption.

There are two ways of finding the volume of a pyramid.

[tex]\tt V=\frac{lwh}{3}[/tex][tex]\tt V=\frac{(4in)(2in)(5in)}{3}[/tex][tex]\tt V=\frac{40in}{3}[/tex][tex]\tt V={13.33^3}[/tex]Therefore, the volume of a pyramid is 13.33in³
2. [tex]\large\tt V = \frac{Bh}{3}[/tex]
Where [tex]\longrightarrow\tt B = l \times w[/tex]
[tex]\longrightarrow\tt B = 4in \times 2in[/tex]
[tex]\longrightarrow\tt B = {8in^2}[/tex]
[tex]\tt V = \frac{Bh}{3}[/tex][tex]\tt V = \frac{4in^2 \times 5in}{3}[/tex][tex]\tt V = \frac{40in}{3}[/tex][tex]\tt V = {13.33^3}[/tex]Therefore, the volume of a pyramid is 13.33in³

Suponga que el monto promedio de compras por cliente de una empresa es de $128.45 y una desviación de $18.26
Answer:
Asumiendo que la distribución de las compras sea normal, tenemos:
_
x = 128.45
σ = 18.26
a)
x = 100
Normalizamos:
.......... _
z = (x - x) / σ
z = (100 - 128.45) / 18.26
z = -28.45 / 18.26
z ≅ -1.56
Buscando en la tabla de áreas bajo la curva normal tipificada (de 0 a z) obtenemos que para z = 1.56 la probabilidad es de 0.4406 = 44.06%. Esta es P(-1.56 < z < 0) = P(0 < z < 1.56).
Como preguntan P(x > 100), tenemos que
P(x > 100) = 0.5 + P(-1.56 < z < 0) = 0.5 + 0.4406 = 0.9406
La probabilidad de que un cliente compre más de $100 es del 94.06%.
=======
b)
x = 150
Normalizamos:
.......... _
z = (x - x) / σ
z = (150 - 128.45) / 18.26
z = 21.55 / 18.26
z ≅ 1.18
Buscando en la tabla de áreas bajo la curva normal tipificada (de 0 a z) obtenemos que para z = 1.18 la probabilidad es de 0.3810 = 38.10%. Esta es P(0 < z < 1.18).
Como preguntan P(x > 150), tenemos que
P(x > 150) = 0.5 - P(0 < z < 1.18) = 0.5 - 0.3810 = 0.1190
La probabilidad de que un cliente compre más de $150 es del 11.90%.
=======
c)
x = 120
Normalizamos:
.......... _
z = (x - x) / σ
z = (120 - 128.45) / 18.26
z = -8.45 / 18.26
z ≅ -0.46
Buscando en la tabla de áreas bajo la curva normal tipificada (de 0 a z) obtenemos que para z = 0.46 la probabilidad es de 0.1772 = 17.72%. Esta es P(-0.46 < z < 0) = P(0 < z < 0.46).
Como preguntan P(x < 120), tenemos que
P(x < 120) = 0.5 - P(-0.46 < z < 0) = 0.5 - 0.1772 = 0.3228
RESPUESTA:
La probabilidad de que un cliente compre menos de $120 es del 32.28%

from the attached question ;
for smoking
1 = smokes , 0 = do not smoke
For Independent variable
1 = ban at workplace , 0 = not ban at workplace.
sex : male = 0 , female = 1
a) Assuming Mr. A is not subject to a workplace smoking ban
P ( Mr. A smokes ) = 15.15%
b) Assuming Mr. A is subject to a workplace smoking ban
determine effect on P ( Mr. A smokes )
The effect on The probability of smoking is that the p( smoking ) will reduce from 15.15% to 11.70%

The surface area of the prism will be equal to 366 square meters.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any object is called the surface area.
Given that:-
A triangular prism has a height of 9 meters and a triangular base with the following dimensionsThe surface area of the prism will be calculated as:-
Surface area = Sum of the area of all sides
There are three rectangle faces and two triangular faces in the triangular prism.
Surface area = 3 ( area of rectangle) + 2 (area of triangle)
Suraface area= 3 ( 10 x 9 ) + 2 [( 1/2)(16 x 6)]
Surface area = 270 + 96 = 366 square meter.
Therefore the surface area of the prism will be equal to 366 square meters.

The prism below is made of cubes which measure 1/3 of an inch on one side what is the volume
Answer:
Volume of rectangular prism = 10/9 inch³
Step-by-step explanation:
Given:
Size of each cube = 1/3 inch
Find:
Volume of rectangular prism
Computation:
Length of rectangular prism = 2 x [1/3]
Length of rectangular prism = 2/3 inch
Width of rectangular prism = 3 x [1/3]
Width of rectangular prism = 3/3
Width of rectangular prism = 1 inch
Height of rectangular prism = 5 x [1/3]
Height of rectangular prism = 5/3 inch
Volume of rectangular prism = Length x Width X Height
Volume of rectangular prism = [2/3] x [1] x [5/3]

Fatheya and Fatema, along with 30 other people, sign up to audition for a talent show. Contestants are called at random to perform for the judges. What is the probability that Fatheya will be called to perform first and Fatema will be called second?
So there's 30 people or slots. The odds that Fatheya will be chosen to perform first is 1/30. But now there's one less slot.
Now with Fatema, there's 29 slots, so there's a 1/29 chance. Then combine these values by multiplying them:
1/30 * 1/29 = 1/870

Step-by-step explanation:
<2=48
<3=93
<2 and <4 are equal to each other because they are alternate interior angles
93+48=141
180-141=39
Answer:
∠5 = 39º
Step-by-step explanation:
∠1 + ∠2 + ∠3 = 180
∠1 + 48 + 93 = 180

5 lbs. of organic red potatoes cost
$6.00. What is the price per lb?
Answer:
0.83333333333
Step-by-step explanation:
5 lbs. of organic red potatoes cost $6.00. The price per pound of organic red potatoes is $1.20.
To find the price per pound of organic red potatoes, we can divide the total cost by the weight in pounds.
Price refers to the monetary value or amount that is assigned or charged for a product, service, or commodity. It represents the cost or value that a buyer is required to pay in exchange for obtaining or acquiring something.
Given that 5 lbs. of organic red potatoes cost $6.00, we can set up the following equation:
Price per pound = Total cost / Weight in pounds
Price per pound = $6.00 / 5 lbs.
Dividing $6.00 by 5 pounds gives us:
Price per pound = $1.20
Therefore, the price per pound of organic red potatoes is $1.20.
