Step-by-step explanation:
One of Natalia's professors claims that 13% of the students at their college frequently wear hats. Natalia feels that the actual rate is much lower. She selects a random sample of 100 students at the college and finds that only 9 of them wear hats frequently. To determine if her data provide convincing evidence that the true proportion is less than 13%, she conducts 200 trials of a simulation. Natalia is testing the hypotheses. H o p = 13% and Ha p< 13%, where p = the true proportion of students at the college who frequently wear hats. Based on the results of the simulation, what is an estimate of the P-value of the test?

Create a factorable polynomial with a GCF of 6. Rewrite that polynomial in two other equivalent forms. Explain how each form was created.
Answer:
Answer: the equivalent form of 6(2x+3x+10) are 12x+18x + 60 and 30x+60.
Hope this helps
Answer:
The equivalent form of 6(2x+3x+10) is 12x+18x + 60 and 30x+60.
Explanation:
12x+18x + 60 is one of the equivalent form of 6(2x+3x+10) To get another equivalent form we combine like terms.
30x + 60 is the equivalent form of 6(2x+3x+10)
A rectangular carport has area of one 50 ft.The width of the carport is 5 feet less than twice its length. Find the length and width of the carport
Width= ? feet,
Length= ? feet
Answer:
[tex]Length = 10ft[/tex]
[tex]Width = 15ft[/tex]
Step-by-step explanation:
Given
[tex]W= Width\\ L = Length[/tex]
[tex]Area = 150[/tex]
[tex]W=2*L- 5[/tex]
Required
Determine the dimension
Area is calculated as:
[tex]Area = L * W[/tex]
So, we have:
[tex]L * W = 150[/tex]
Substitute: [tex]W=2*L- 5[/tex]
[tex]L * (2*L-5) = 150[/tex]
[tex]L * (2L-5) = 150[/tex]
Open bracket
[tex]2L^2 - 5L = 150[/tex]
Rewrite as:
[tex]2L^2 - 5L - 150=0[/tex]
Expand
[tex]2L^2 -20L + 15L - 150 = 0[/tex]
Factorize:
[tex]2L(L -10) + 15(L - 10) = 0[/tex]
[tex](2L + 15) (L - 10) = 0[/tex]
Split
[tex]2L + 15=0[/tex] or [tex]L -10 = 0[/tex]
Solve for L
[tex]2L =-15[/tex] or [tex]L = 10[/tex]
L cannot be negative
So:
[tex]L = 10[/tex]
Substitute [tex]L = 10[/tex] in [tex]W=2*L- 5[/tex]
[tex]W = 2 * 10 - 5[/tex]
[tex]W = 20 - 5[/tex]
[tex]W = 15[/tex]
Hence:
[tex]Length = 10ft[/tex]
[tex]Width = 15ft[/tex]

According to Wine-Searcher, wine critics generally use a wine-scoring scale to communicate their opinions on the relative quality of wines. Wine scores range from to , with a score of indicating a great wine, indicating an outstanding wine, indicating a very good wine, indicating a good wine, indicating a mediocre wine, and below indicating that the wine is not recommended. Random ratings of a pinot noir recently produced by a newly established vineyard in follow: Excel File: data07-11.xlsx 87 91 86 82 72 91 60 77 80 79 83 96 a. Develop a point estimate of mean wine score for this pinot noir (to decimals).
Answer:
[tex]\=x=82[/tex]
Step-by-step explanation:
From the question we are told that:
Data
[tex]\begin{center}\begin{tabular}{ |c|c|c|c|c|c| } 87& 91& 86& 82& 72&91 \\ 60& 77& 80& 79& 83&96 \end{tabular}\end{center}[/tex]
Generally the equation for Point estimate [tex]\=x[/tex] is mathematically given by
[tex]\=x=\frac{\sum_x}{n}[/tex]
[tex]\=x=\frac{87 +91+ 86+ 82 +72 +91+ 60+ 77 +80+ 79+ 83 +96}{12}[/tex]
[tex]\=x=\frac{984}{12}[/tex]

What is the approximate length?
9514 1404 393
Answer:
(a) 75.5
Step-by-step explanation:
There are two ways you can work this.
Pythagorean theorem
Triangle CMP is a right triangle. CM = AC = 55. CP = CB -PB = 55 -15 = 40. Then length PM can be found from ...
PM² +CP² = CM²
PM = √(CM² -CP²) = √(55² -40²) = √1425 ≈ 37.749
The length MN is twice the length of PM, so is ...
MN = 2×PM = 2×37.349 = 75.498
The length of MN is about 75.5.
__
Using chord relationships
The products of the different lengths for the same chord are the same for the crossed chords.
AP×PB = MP×PN
We know MP = PN, so ...
MP = √(AP×PB) = √((55+40)(15)) = √1425
As before, MN = 2×MP = 2√1425
MN ≈ 75.5

In Devon's school, the morning session runs for a total of 182 minutes. The morning session
includes 4 class periods of equal length and a homeroom period that lasts for 10 minutes.
Using the variable m to represent minutes, write an equation that can be used to find the
length of each class period. Then solve for m.
Answer:
Every class period is 43 minutes long.
Equation:
(m - 10) ÷ 4

Answer:
c = 2.9 yards
Step-by-step explanation:
2c = 42.4 - (18.3 x 2)
2c = 42.4 - 36.6
2c = 5.8
c = 5.8 / 2
c = 2.9 yards

Which coordinate grid shows points and plotted at (4.3)
Answer:
B
Step-by-step explanation:
(x-coordinate, y-coordinate) and the horizontal axis refers to the x-axis and the vertical axis refers to the y-axis.
Point D is at (-4,-2) on a coordinate plane, what would be the ordered pair if
you reflected point D horizontally? How do you know?
Answer:
As such, in first quadrant, both the coordinates (x and y) are positive and both are negative in third quadrant. In second quadrant, y is positive and x is negative, while in fourth quadrant x is positive and y is negative, As (-4, -2) has both x and y coordinates negative, it will be found in third quadrant

x^2 + 3x - 9 = 0
Answer:
Step-by-step explanation:
x^2 + 3x - 9 =0
By comparing with the equation ax^2+bx+c = 0,
we get,
a = 1, b=3, c = -9
we know the formula for x is,
x = (-b±√(b^2 - 4ac))/2a
x = (-3±√45)/2
x = (-3±3√5)/2
x = (-3+3√5)/2, (-3-3√5)/2
Answer:
2 solutions. x = -3/2 + 3/2 * sqrt(5) and x = -3/2 + -3/2 * sqrt(5)
Step-by-step explanation:
Let's solve your equation step by step.x^2 + 3x −9 = 0
For this equation: a=1, b=3, c=-9
1x^2 + 3x+ −9 = 0
Step 1: Use quadratic formula with a=1, b=3, c=-9.
x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex])/2a
x = (-3 ± [tex]\sqrt{3^2 - 4(1)(-9)}[/tex])/2a
x = (-3 ± [tex]\sqrt{45}[/tex])/2
x = -3/2 + 3/2 * sqrt(5) or x = -3/2 + -3/2 * sqrt(5)

Find the area base = x+8 height x+7
9514 1404 393
Answer:
x² +15x +56
Step-by-step explanation:
We presume these are dimensions of a rectangle, so the area is their product.
A = (x +8)(x +7) = x(x +7) +8(x +7) = x² +7x +8x +56
A = x² +15x +56
