7.Which equation is a quadratic model for the data set?
A) y=1.1556x^1.9375
B) y=11.6018*1.2207^x
C) y=20.9330x-93.8918
D) y=1.2246x^2-5.0511x+24.288-
The quadratic model for the data set is y = 1.2246x² - 5.0511x + 24.288
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
Polynomials are classified based on degree as linear, quadratic, cubic etc.
The standard form of polynomial (of degree 2) is:
y = ax² + bx + c
The quadratic model for the data set is y = 1.2246x² - 5.0511x + 24.288

Diana y Juan están considerando abrir una cafetería. Semanalmente ellos gastarian
$1.348 en costos fijos de utilidades y mantenimiento. Cada almuerzo tiene un costo
de producción de $3.50. por lo que piensan vender cada almuerzo en $8.
a. ¿Cuántos almuerzos deben elaborar semanalmente si desean obtener una
ganancia de $775 para cada uno?
Answer:
Unidades a vender= 644 unidades
Step-by-step explanation:
Dada la siguiente información:
Costos fijos= $1.348
Costo unitario= $3,5
Precio de venta= $8
Ganancia deseada= 775*2= $1.550
Para calcular el número de unidades a vender, debemos usar la siguiente formula:
Unidades a vender= (costo fijo + ganancia deseada) / contribución marginal unitara
Unidades a vender= (1348 + 1550) / 4,5
Unidades a vender= 644 unidades

Subtract 8 from me. Then add 21. If you divide me by 4 and add 21 you get 29. What number am I?
Answer:
19
Step-by-step explanation:
x - 8 + 21 ÷ 4 + 21 = 29
x - 8 + 21 ÷ 4 = 29 - 21
= 8
x - 8 + 21 = 8 x 4
= 32
x - 8 = 32 - 21
= 11
x = 11 + 8
= 19
Therefore the number is 19. A bit confusing to me at first but I solved it :)

The age of a cat 2 years or older can be approximately converted into human years by multiplying by 4 and adding 16. Complete the table to represent the relationship between cat age and human years.
Answer:
Step-by-step explanation:
If the age of a cat is represented by 'x' and human years by 'y', relation between the age of cat and human years will be,
y = 4x + 16 [multiplying cat's age by 4 and by adding 16]
Now from the given table,
If x = 2,
y = 4×2 + 16
= 24
If y = 3,
y = 4×3 + 16
= 28
If x = 4,
y = 4×4 + 16
= 32
If x = 5,
y = 5×4 + 16
= 36
If x = 6,
y = 6×4 + 16
= 40
Cat age 2 3 4 5 6
Human years 24 28 32 36 40

Write an equation in point-slope form and slope-intercept form for
each line.
the line passes through (4, 7), slope = 2
Answer: y=2x-1
Step-by-step explanation:
Equation of a line that passes through (a,b) and have slope m is given by :-
[tex](y-b)=m(x-a)[/tex] [point slope form]
Given, Point = (4,7) , m= 2
Equation in point slope form : [tex](y-7)=2(x-4)[/tex]
To write in slope intercept form (y=mx+c) , we need to simplify it
[tex]y-7= 2x-8\\\\\Rightarrow\ y-2x=-8+7\\\\\Rightarrow\ y-2x=-1\\\\\Rightarrow\ y=2x-1[/tex]
Hence, y=2x-1

A casting director wishes to find one male and one female to cast in his play if he plans to audition seven males and eight females in how many different ways can this be done
There are 7 males and 8 females out of which we 1 male and 1 female is to be selected.
Number of ways to select 1 male from 7 are [tex]^7C_1[/tex].
Number of ways to select 1 female from 8 are [tex]^8C_1[/tex].
So, number of ways to select 1 male and 2 female is :
[tex]n = ^7C_1 \times ^8C_1\\\\n = 56[/tex]
Therefore, total number of ways are 56.
Hence, this is the required solution.
Claim: Fewer than 92% of adults have a cell phone. In a reputable poll of 1207 adults, 85% said that they have a cell phone. Find the value of the test statistic,
Round to two decimal places as needed
Answer:
- 6.547
Step-by-step explanation:
Given that:
Sample size (n) = 1207
p = 0.85
p0 = 0.92
The test statistic :
Z = (p - p0) / √(p0(1 - p0) / n)
Z = (0.85 - 0.92) / √(0.92(1 - 0.85) / 1207)
Z = - 0.07 / √(0.92(0.15) / 1207)
Z = - 0.07 / √0.0001143
Z = - 0.07 / 0.0106926
Z = - 6.5465446
Z = - 6.547

Item: Pipe
Model: Length: 5 ft
Actual: Length:___ft
Answer:
75ft
Step-by-step explanation:
Hello There! With the information given in the problem we can set up a ratio in order to help us solve for the actual length that the model is scaled upon.
This ratio can be written as:
[tex]\frac{1ft}{15ft}[/tex]
From this we just set up another ratio in relation to the original. In this one we will be solving for x.
[tex]\frac{1ft}{15ft}[/tex] x [tex]\frac{5ft}{x}[/tex]
After solving for x we find that the actual model should be roughly 75ft.
Hope this helps!

The width of a piece of paper is 8.5in the length is 11in and the thickness is 0.0037inches there are 2700sheets sitting in a cabinet by the copy machine what is the volume of occupied by the paper.
Answer:
934.2 in³
Step-by-step explanation:
The following data were obtained from the question:
Width (W) = 8.5 in
Length (L) = 11 in
Thickness (T) = 0.0037 in
Number of paper = 2700 sheets
Volume occupied by the 2700 sheets of paper =?
Next, we shall determine the volume of 1 sheet of paper. This can be obtained as follow:
Width (W) = 8.5 in
Length (L) = 11 in
Thickness (T) = 0.0037 in
Volume (V) =?
Volume = Length × Width × Thickness
Volume = 11 × 8.5 × 0.0037
Volume = 0.346 in³
Thus, the volume of 1 sheet of paper is 0.346 in³
Finally, we shall determine the volume occupied by the 2700 sheets of paper as follow:
Volume of 1 sheet of paper = 0.346 in³
Volume of 2700 sheets of paper =?
1 sheet of paper occupied 0.346 in³.
Therefore, 2700 sheets of paper will occupy = 0.346 × 2700 = 934.2 in³
Thus, the volume occupied by the 2700 sheets of paper is 934.2 in³.

What is Place Value?In math, every digit in a number has a place value. Place value can be defined as the value represented by a digit in a number based on its position in the number. For example, the place value of 7 in 3,743 is 7 hundred or 700. However, the place value of 7 in 7,432 is 7 thousand or 7,000.
Given here: The number 56
To convert it to 506 we must add 506-56=450
∴ we must 45×10 to 56 to convert it to 506
Hence, 45 tens must be added to get 506
