Simply plug 3 into the equation.
[tex]f(3) = 3(3)^2+2(3) = 3(9) + 6 = 27 + 6 = 33\\\\\\f(3) = 33[/tex]
Answer:
Step-by-step explanation:
Plugin x = 3 in the function
f(x) = 3x² + 2x
f(3) = 3*(3)² + 2*3 {3² = 3*3 = 9}
= 3*9 + 6
= 27 + 6
f(3) = 33

Find all solution(s) of the quadratic equation x2 – 100 = 0.
Answer:
10 and -10
Step-by-step explanation:
difference of two squares:
x² - 100 = 0
(x + 10)(x - 10) = 0
x + 10 = 0; x = -10
x - 10 = 0; x = 10

A gross refers to a group of 144 items (a dozen or a square dozen, 122). A great gross refers to a group of 1728 items (a dozen gross or a cubic dozen, 123). A small gross or a great hundred refers to a group of 120 items (ten dozen, 10×12).
if a×b=2a=b, evaluate 4×3 do not answer with a link,photo,file.
If you are comparing a*b=4*3, a = 4 and b = 3.
This would mean that 2a = 8.
If a×b=2a=b, evaluate 4×3 , Based on the given equation, the result of 4 × 3 is 12.
To evaluate 4 × 3 using the given information, we substitute the values of a and b into the equation.
An equation is a mathematical statement that shows the equality of two expressions or quantities. It consists of an equal sign (=) placed between the two sides of the equation. The expressions on each side of the equal sign are referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation.
Equations are used to represent relationships and solve for unknown values. They can involve variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The goal is to find the value or values of the variable(s) that make the equation true.
Given: a × b = 2a = b
Let's assign a = 4 and b = 3:
4 × 3 = 2(4) = 3
Simplifying the equation:
12 = 8 = 3
Therefore, based on the given equation, the result of 4 × 3 is 12.

Answer:
LA = 20π square units
SA = 36π square units
V = 16π cubic units
Step-by-step explanation:
The value of the radius is needed before any area calculations can be done. It can be found from the Pythagorean theorem:
r² + 3² = 5²
r = √(25 -9) = 4
__
The lateral area is given by the formula ...
LA = πrs . . . . . where r is the radius and s is the slant height
LA = π(4)(5)
LA = 20π square units
__
The surface area is the sum of the lateral area and the base area. The latter is the area of a circle of radius 4.
SA = πr² + LA
SA = π(4²) +20π = 16π +20π
SA = 36π square units
__
The volume is given by the formula ...
V = 1/3πr²h
V = 1/3π(4²)(3) = 16π
The volume is 16π cubic units.

Problem 4: Price-fixing Litigation(5 points) Background: Multiple regression is sometimes used in litigation. In the case of Cargill,Inc. v. Hardin, the prosecution charged that the cash price of wheat was manipulated in violation of the Commodity Exchange Act. In a statistical study conducted for this case, a multiple regression model was developed to predict the price of wheat using three supply- and demand explanatory variables. Data for 14 years were used to construct the regression equation, and a prediction for the suspect period was computed from this equation. The value of R2 was 0.989. Problem: Cargill, Inc. had priced the wheat at $2.13. Their legal team needed to demonstrate that the price was not artificially depressed. For purposes of this project, suppose the sample size was 100. Requirements: 1.(2.5 points) For the relevant case, the fitted model gave the predicted value $2.136 with standard error $0.013. Based on this, determine the 95% prediction interval for the price of wheat. 2.(2.5 points)
Answer:
[tex]Critical\ value=1.66039[/tex]
Step-by-step explanation:
From the question we are told that:
Sample size [tex]n=100[/tex]
Mean price of wheat [tex]\=x=2.136[/tex]
Standard error [tex]S_e=$0.013[/tex]
95% prediction interval
Generally the equation for 95% confidence is mathematically given by
[tex]\alpha=1-95\%[/tex]
[tex]\alpha=1-0.95[/tex]
[tex]\alpha=0.05[/tex]
Generally the degree of freedom [tex]d_f[/tex] is mathematically given by
[tex]d_f=n-1[/tex]
[tex]d_f=100-1[/tex]
[tex]d_f=99[/tex]
Generally the critical [tex]t_{\alpha,df}[/tex] value is mathematically given by
[tex]t_{(0.05,99)}[/tex]
[tex]t_{(0.05,99)}=1.66039[/tex]
Therefore the critical associated with 95% predication interval is [tex]Critical\ value=1.66039[/tex]

Step-by-step explanation:
Answer:
No, 0.85 is greater.
Step-by-step explanation:
Imagine a number line, with one at the end and 0.1 at the other end. With .85, It would be closer to one, with 0.6 being behind 0.85. The only other reason that 0.6 is greater than 0.85 is if they are converted to fractions.

What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2pir.
The area of a circle is πr².
We have,
if a tangent and a chord are drawn from a point outside a circle, and the point of intersection of the tangent and the circle is labeled as point P, then the length of the tangent squared is equal to the product of the lengths of the two segments of the chord:
Now,
From the figure,
(2x - 9)² = 27 (2x + 2)
We can start by simplifying the left-hand side of the equation:
(2x - 9)² = 27 (2x + 2)
4x² - 36x + 81 = 54x + 54
Now we can move all the terms to one side and simplify:
4x² - 90x + 27 = 0
Next, we can use the quadratic formula to solve for x:
x = (-b ± √(b² - 4ac)) / 2a
where a = 4, b = -90, and c = 27.
Plugging in the values:
x = (-(-90) ± √((-90)² - 4(4)(27))) / 2(4)
x = (90 ± √(8100 - 432)) / 8
x = (90 ± √(7668)) / 8
x = (90 ± √(447)) / 8
x ≈ 11.16 or x ≈ 1.09
Rounding to a whole number.
x = 1
Therefore,
The value of x in the circle is 1.

Answer:

Step-by-step explanation:
Bob wants to invest his $3000 in an account that gets 3.4% interest rate compounded monthly, how much money will he have after 12 years? (round to nearest whole number)
Answer:
After 12 years Bob will have $ 4,508.80 in his account.
Step-by-step explanation:
Given that Bob wants to invest his $ 3000 in an account that gets 3.4% interest rate compounded monthly, to determine how much money will he have after 12 years the following calculation must be performed:
3000 x (1 + 0.034 / 12) ^ 12x12 = X
3000 x (1 + 0.0028333) ^ 144 = X
3000 x 1.0028333 ^ 144 = X
3000 x 1.502932 = X
4,508.80 = X
Therefore, after 12 years Bob will have $ 4,508.80 in his account.

Answer:
66 cm²
Step-by-step explanation:
The area of the polygon is the sum of the areas of the triangle and the rectangle it sits on. The dimensions of the triangle can be found by examining the top/bottom dimensions shown and the left/right dimensions shown.
The width (base) of the triangle is the difference between the lengths of the bottom and top horizontal lines: (12 -9) cm = 3 cm.
The height of the triangle is the difference between the lengths of the left and right sides of the figure: (9 -5) cm = 4 cm.
The dimensions of the rectangle are shown a the bottom and the left sides of the figure.
triangle area = 1/2bh = 1/2(3 cm)(4 cm) = 6 cm²
rectangle area = LW = (12 cm)(5 cm) = 60 cm²
Total polygon area = 6 cm² + 60 cm² = 66 cm²

A Pew Research study finds that 23% of Americans use only a cell phone, and no land line, for making phone calls (The Wall Street Journal, October 14, 2010). A year later, a researcher samples 200 Americans and finds that 51 of them use only cell phones for making phone calls.Set up the hypotheses in order to determine whether the proportion of Americans who solely use cell phones to make phone calls differs from 23%.
Answer:
We accept H₀ sample does not give evidence to support that the proportion of Americans who solely use cell phone differs from 23 %
Step-by-step explanation:
A pew research finds that 23 % ( μ ) of Americans use only cell phone
Sample Information
sample size n = 200
x₁ = 51 then p₁ = 51/200 p₁ = 0,255
and q₁ = 1 - p ₁ q₁ = 1 - 0,255 q₁ = 0,745
Sample big enough for the approximation of the binomial distribution to the normal distribution
p₁*n = 0,255 * 200 = 51 > 5 and q₁*n = 0,745* 200 = 149 > 5
Test hypothesis
Null hypothesis H₀ p₁ = μ = 0,23
Alternative hypothesis Hₐ p₁ ≠ 0,23
Is a two tail test. We choose CI = 95 % then significance level is α = 0,05 %
α = 0,05 as is a two tail test α/2 = 0,025
from z-table z(c) = 1,96
To calculate z(s) = ( x - μ ) /√p₁*q₁/n
z(s) = ( 0,255 - 0,23 )/√0,255*0,745/200
z(s) = 0,025 / 0,0308
z(s) = 0,81
Comparing z(s) and z(c)
z(s) < z(c) 0,81 < 1,96
Then z(s) is in the acceptance region: we accept H₀
