Answer:
27 > q
Step-by-step explanation:
Solving an algebraic inequality is very similar to solving an algebraic equation, one uses inverse operations. One major difference between the two is that when one multiplies or divides an algebraic inequality by a negative number, one must remember to flip the inequality sign.
55 - 5q > 4 ( 7 - q )
Distribute,
55 - 5q > 28 - 4q
Inverse operations,
55 - 5q > 28 - 4q
+5q +5q
55 > 28 + q
-28 -28
27 > q

Quadrilateral FLAG is a parallelogram because opposite sides are parallel.
Quadrilateral FLAG is only a quadrilateral because no sides are congruent and no
sides are parallel.
Quadrilateral FLAG is a trapezoid because only one pair of sides are parallel.
Answer:

Hypothesis Testing is the use of statistics to determine the probability that a given claim is true. In Part II of this project, you will choose a data set, review claims and perform hypothesis testing and make a decision. You will then complete a write-up that includes the calculations. The government logs the number of documented births, deaths, marriages and divorces; however, it is possible to have undocumented cases. In part II of this project, you are going to test claims about total births, deaths, marriages and divorces. Deliverables Choose a Data Set. Go to https://www.cdc.gov/nchs/products/nvsr.htm (Links to an external site.) In the search bar type: Births, Marriages, Divorces, and Deaths screenshot of CDC website toolbar Pick a DataSet and download the PDF document and make note of the volume, number, and date. For example you could use the National Vital Statistics Reports, screenshot of National Vital Statistics Reports webpage Pick the same month/year combination for each data set. For example, choosing September of 2009. screenshot of example dataset Preliminary Calculations Create a summary table for 1. Live Births, 2. Deaths, 3. Marriages, and 4. Divorces highlighting the mean, median, sample standard deviation, minimum and maximum values for each the data sets. You will have FOUR tables using the list of values of each state, the District of Columbia and Puerto Rico (You will have 52 numbers for each data set). Summary Table for _________ Mean Median Standard Deviation Minimum Maximum Hypothesis Testing With the information that you gather from the summary tables, test the following (you can use excel when appropriate): Determine if there is sufficient evidence to conclude the average amount of births is over 5000 in the United States and territories at the 0.05 level of significance. Determine if there is sufficient evidence to conclude the average amount of deaths is equal to 6000 in the United States and territories at the 0.10 level of significance. Determine if there is sufficient evidence to conclude the average amount of marriages is greater or equal to 2500 in the United States and territories at the .05 level of significance. Determine if there is sufficient evidence to conclude the average amount of divorces is less than or equal to 4000 in the United States and territories at the 0.10 level of significance. For each of the tests above, in your report, be sure to— Clearly state a null and alternative hypothesis Give the value of the test statistic Report the P-Value Clearly state your conclusion (Reject the Null or Fail to Reject the Null) Explain what your conclusion means in context of the data. Lastly, propose and conduct your own test of hypothesis about the Birth, Death, Marriage and Divorce data that you have been analyzing. Make sure to follow the five steps above.

Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.
GI² = IK² + GK²
=> GI² = 3² + 2²
=> GI² = 13
=> GI = √13

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

The area of a rectangular closet is 18 square feet. The perimeter is 18 feet. What are the dimensions of the closet?
Answer:
Height: 6ft
Base: 3 ft
Step-by-step explanation:
Factors of 18 are: 1, 2, 3, 6, 9, 18
18 and 9 are both two big because of perimeter...this rules out 2 and 1 because those are the factor pairs which leaves 6 and 3
Area = bh = 3*6 = 18
Perimeter is adding all the sides twice
(6*2) + (3*2) = 12 + 6 = 18
Area = 18 Correct
Perimeter = 18 Correct

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]

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

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
In a shoe store survey there are 200 customers.
Given in the table is that, people using basketball shoes, not using basket shoes and then there is also classification of people using running or non running shoes.
We have been asked what percentage of people have basketball shoes.
People having basket ball shoes = 0.18 × 200 + 0.28 ×200
= 64
